Positive and Negative Airflow Testing / be quiet! Pure Base 500DX (w/ timelapse build)

[@KitGuruTech]

we will be here at 2pm UK time to chat with anyone who has any questions they need help with !

[@Oranskyyy]

@KitGuruTech Hi, I have a question. So if I put 2 shadow wings 2 140mm (slightly worse then silent wings I believe - at least cheaper :D) as an intake on the front and 2 shadow wings 2 120mm as exhaust (rear and top) will I have a positive pressure then?

[@icedmiko]

Hi. I have a question. i would put the 3 fans included in the case as exhaust ( 2 at the top and 1 at the rear), then purchase 3 120mm pure wings high speed and install them at the front as intake. Am i right? ( silly question but I have only one chassis fan header available on my motherboard... should i purchase some kind of PWM splitter?) Thanks a lot for your video, very interesting stuff

[@NebulaTraveler2956]

Would it make a difference in the end result (slightly positive fan setup) if you would use the dust covers in front and top?

[@handlealreadytaken]

Starting to like this channel a lot more than some of the other PC focused sites. No wallowing in sarcasm or stupidity. Just straight forward content and sticks to the message.

[@KitGuruTech]

we are a tiny channel compared to the big guys, but its nice to read something like this. the team try hard. appreciate you taking the time to post your thoughts

[@KitGuruJames]

Thanks for the positive comment. It really is nice to hear.

[@spacecy]

Yeap! i love this channel.

[@lemonsmemes5856]

Thoughts on Gamers Nexus?

[@Csubakka1]

The cable management is one of the best i seen in build videos. Good job! Also i agree, the build turned out to be beautiful. No flashy bling stuff... Nice mid-range config too, most of us would be happy to have something like this at home. If i had to write something negative (splitting hairs) there is a tiny bit of gpu sag, and the 750w psu is an overkill :D Thanks for the content!

[@MLife1972]

This answered every question I had about airflow before I upgrade my PC. Thanks a million.

[@BongManCSGO]

Appreciate the time and effort that you guys put into the making of this video. And James is one hell of a PC builder. You absolutely nailed the cable management part

[@BobMotster]

Interesting tests. Do note that setting intake and exhaust RPMs to be equal does not warrant balanced air flow. In order to achieve perfect balance, front and rear mesh holes have to be of the exact same size. Every square millimeter of material matters.

[@Rinsii-y6k]

I have always used a positive pressure config so really good to see results that make my decision a good one.

[@DavideGranato]

Gorgeous build , if I was you I'd give myself a compliment more , it's not just one of the best looking builds in ages , also one of the neatest cable management ever. Well done and may the (slightly) positive (pressure) Spirit win!

[@KitGuruJames]

Thanks! I like to try my best with the available components. 😁

[@DavideGranato]

@@KitGuruJames A pleasure! Just a curiosity of mine , btw. Will you test also 3 fans front/intake + 1 or 2 fans exhaust ?

[@duncanshaw6342]

Hey thanks for the effort. I just got the Pure Base 500DX case after hours of research. Three 140mm fans included non arbg from Amazon. Subscribed. Just transferring my old comp to a new case. Bought it used for $300 US bucks but it came with a Sapphire Tri-X R9 290X OC and by the way it does play games like BF3/Bf4, Cod,Fortnight just fine. I do appreciate your innovative tests. Next time just start with the stock stuff then test. Helped me much and I am not a "Gamer". Thanks and good luck.

Excellent video, the build looks terrific and the information was clear and concise. Thank you very much for posting this and sharing your thoughts.

[@revnto7k]

I have a pure base 500 original with 2 140's up front and 1 140 in the rear, pretty standard config. System is happy unless really heavily stressed. (fans are pure wings 2 900 RPM)

[@christiangruber5824]

Looking at doing positive pressure on my new build. Gonna be nice to see an updated video about it.

[@bunch8]

Thank you for the clear hardware specs nicely laid out in bullet points. Thumbs up !

[@AsphyxGr]

I have the same case with a Ryzen 3900X and the monstrous BeQuiet cooler with the two fans. Even though I don't have issues I decided to improve thermals if applicable, thanks for the very informative video and your overall effort, helps a lot.

[@d.oconnor4047]

​I'm hoping that this shows optimal configs for dust accumulation also. I didn't buy the lancool mesh because it has no dust filter so I went with the phanteks p600s instead, beautiful case. ​I have two 140mm fans in the front and two 120mm fans in the back. I would like to see tests looking into optimal fan RPM configs for different airflow setups. I'm not sure how well two 140mm and 3 120mm fans replicate neutral airflow.

[@KitGuruJames]

Your setup sounds ideal to me, slightly favouring positive pressure so good for thermal performance and dust as long as your front fans are filtered.

[@123cez123]

Subscribed. Love your content and reviews. Keep up the good work.

[@joelwallenius2877]

Thank you very much for this! I have this case and was just wondering what the best fan config is, now I know... you made my heart lighter :-]

[@namesbinge3073]

It's better to achieve positive than negative but the best is balance

[@lecutter9382]

Thank you very much for that excellent review. Exactly what I needed to know. I think most people - gamers at least - are always looking out for the best combination of performance and quietness in a system and/or case. For me I think the DX ticks all the boxes on both of those things. I could do without the LEDs at the front and glass side as I don't care about RGB - can you turn the LEDs in the case off when it's running? I'll probably just tint the glass really dark.

[@johnprosser2142]

I would love to see the Acoustics added into this video and see what the dba was with each configuration.

[@ucrjedi]

I’m glad that you did this video but it was not a fair comparison. One setup had four fans used while the others had only three fans. You bet that’s going to affect the temperature. I’m surprised that this was not noticed prior to filming.

[@qrogueuk]

Currently running positive air flow on my R6 (no window) 3X140 + 1x120 intake and 3 x140 exhaust

[@masmur]

just the thing i want to know more about, what a coincidence :XD

[@bennu9343]

Would it be fine to put two 140 mm stock fans on the right side and one on the left

[@harrisonbanda4921]

Your cable management is soooooooooo clean daym

[@Toadyru]

The case makes it easy.....I bought one. Best cable management build in a long time.

[@Dennis-vh8tz]

I'd probably setup this case with 2*140mm or 2*120mm exhaust and 3*120mm intake.

[@michaellovejoy5299]

Same. I’d use three Phanteks t30-120’s @ performance for intake and two Phanteks t30-120’s @ hybrid for exhaust.

[@marcosad2]

thank you so much for this video!!!

[@sharthakghosh970]

In the negative setup, where was the intake fan placed ? Ideally should be below so the hot GPU air can easily travel to the top

[@Virosaa]

one of the best cases for the money

[@taomahNEGEV]

Should have also tested the thermal effects of the installed filters.

[@Norasthaine]

Hello @KitGuruTech, Thank you for this video, I have only just discovered it. I am loyal to be quiet! brand. I have the same 850W power supply and 4 Silent Wings 3 140 mm fans: 2x High Speed for the front and potentially 1x rear and 1x at the top. If I understand correctly (I'm French frog ^^), the best configuration is with 3 fans in positive pressure: 2x front, 1x rear? The 4th fan at the top, does not do better in the end? And the whole thing would make more noise in the end? On the other hand, to cool a Ryzen 7 5800X processor, do you recommend a Dark Rock 4 or Dark Rock 4 Pro cooler? Depending on the cooler, do you recommend adding or removing the top cooler? And last stupid question, which rubber wedge mount (2 positions, S and L) do you use depending on the location of the Silent Wings 3 fans? S for intake fans (0 spacing) and L for exhaust fans (a small space)? The instructions are not clear... Thank you, have a nice day!

[@lchanceiv]

What do you think of 3x120mm front intake(silent wings pwm) and 3x140mm(stock fans) exhaust? This should create positive airflow.

[@bentracey8324]

Thank you for this video

[@KitGuruTech]

My pleasure

[@Dioramarama_Collectibles]

When I first got this case, I had 1 140 up front, 1 140 in the rear and 1 140 up top and everything thing seemed fine. Then I added another 140 in front and something seems off. Is this a case of "less is more," do I not need a 4th fan and should I move the top one to the front to have just 2 in front and 1 in back?

[@samirsalkunic5321]

Hey, this is kinda the vid i was looking for, as i'm having a bit of a problem with my 500DX. So yeah, i got it, and i am using the three stock coolers provided with it (Pure Wings 2 140mm), and when i am playing something a bit more new (Sniper Elite 4, Expeditions Viking lately), basically when it is under the load i can totally feel the hot air bouncing off the wall behind my pc table and reflecting back into my legs and generally creating quite a temperature beneath my pc table. It's not much of an issue now, but i am dreading the thought of it happening when the summer comes, my balls are gonna sweat off. I am not using the case in the default configuration, the one on the top cover i have had moved as a second front intake cooler, so i am having a 2 140mm set to intake on the front panel, and the third 140mm set on the back panel of the case. The case is sitting in the bottom right side beneath the table, and the table doesn't have the typical 4 legs, but it's more like two plank sides protruding from the top plank, and there is like a plank in the middle reinforcing the left to right side (legs as it may).The case is moved to about 25 cm from the wall behind, with the reinforcing plank of the table being somewhat obstructive halfway there narrowing the distance partially to about 20 cm maybe. It would be really easier to just be able to show the picture of the setup but that's basically it. The exhaust fan on the back panel is totally killing the temp beneath the table, so if you cguys would have an advice, it would te appreciated.

[@benadkins7695]

Just because you used a certain amount of fans for either the exhaust or the intake doesn’t mean the chassis is positive or negative, there are numerous other factors such as RPM that have to be taken into play. Also, you sort of neglect showing the actual performance of the case by not having the tempered glass on or the filters. I understand that’s a factor that will vary by case to case, but that’s far more realistic than having a completely open case. Regardless, this was a solid video mate, hope to see more.

[@elazul1986]

Hello there. This was almost exactly what I have been looking for. First of all, 12 hours testing, thank you for your contribution for those who want to know about the outcome of these tests. I would like to go with Balanced pressure but unfortunately the case comes with 3x140mms and I don't want to put those 140mms aside and buy new 120mms. I was wondering what kind of a big change would I expect if I were to use 2x140mms in the front as intake and 2x140mms exhausting fans one being on top and the other being in the rear. Basically I just want to add one more 140mm to the front. How different would it be than the balanced pressure as it was the outcome of 120mms instead of 140mms? Thanks.

[@a-sway-shuriken600]

does it have it's own fan controller and led controller (if yes can it support lian li fans?

[@licustoms]

I didn't see any mention of fan orientation for the power supply. Did you pull air from outside of the case into the power supply and out the back of the case, or did you pull air from inside of the case and out the back? I suspect you had the power supply with the fan pulling in air from outside of the case and out the back of the PC but just thought I would ask because it does make a difference even with a power supply shroud.

[@En3rg3t1c]

Hello, I have a pure base 500 dx case, I planned to put LIGHT WINGS fans, the question is where and what to put, I mean 120-140mm with what speed, since I don’t understand well, put 3 on the front panel 1 on the back and 2 on top or 1 on top please advise

[@olafweyer859]

I have the same setup now, also non-pro Dark 4. But... it's all supposed to cool a Ryzen 5800x (it was only 60 Dollars more than the 5600x here in Costa Rica, so, no-brainer). Gonna see if I need to BIOS it into an quasi-5700x, it's not exactly cold down here (and that's probably the "why" of the price difference).

[@johnprosser2142]

How do you think this case would go with 2 140ml the front, 1 120 ml in the back and some sound deadening material on the inside of the roof for quietning and no air going up through the top?

[@IHyperGun]

Hi James, I want to build in this case and want to use the stock fans and a freezer 34 esports duo cpu cooler. Where should I put the 1X 140mm intake fan? At the top of the front? Or should I leave it in the middle? Thanks in advance.

[@Naes3D]

Hey, I'm building a similar setup and I'm wondering if Dark Rock 4 Pro version would fit in there? It looks a bit crammed as is, so I'm not sure if additional fan would squeeze in there. Great video!

[@JOAFINDICHJOA]

It fits without Problems

[@blaisebinu3642]

I really like this case...but unfortunately it’s not available in our area

[@casualonemmo-player2167]

Ive found it usefull to buy cheap incent sticks and then used them all over the case, to see if i got smoke leaking into the case, where it shouldnt... (99/100 times those small areas arent dustfiltered....): then simply adjusted the speed of a fan or two, untill the smokes blows out.. = problem sorted. And less dust. I clean my filters once a month (all intakes have filters). Never had to clean the inside.

[@KitGuruJames]

Yes ive used a fog machine and vape to look at the airflow in the past.

[@branko28]

Beautiful build! I have one question, since I have Be Quiet Dark Rock 4 - how did you manage to mount the cooler and all 4 ram sticks? 😀

[@LucLK]

Hello, I have purchased recently a pc with a be quiet 500dx case, and I have 1 fan at the back, 2 at the top, and 2 at the front. but the ones at the front, do not spin, i never seen them spin so far, are they suposed to be like that, and only start when pc overheats? or maybe is it something that has to do with the fans configuration? I am clearly not a pc expert, thats why I am asking if anybody knows to answer. Cheers !

[@ivanvolchek1187]

It's very cool 👍

[@sceptical4961]

would it possible to mount a sensor display inside the case

[@MrStodderkonge]

Can anyone tell me how the airflow and temperature would be, with a water cooling radiator in the front panel, on this case. Hope to get some answers, been looking around and been unable to find any.

[@laszlosarkozi1385]

Does not make sense to do tests with 120mm fans. This case comes with 3 x 140mm fans. Buyers are more likely to buy some more 140mm fans for this case(that's what I did) because of better airflow and lower noise. Why not use the included fans for test when most people will just use those? I watched this video because I wanted to know which configuration of the originally included three pure wings 2 fans (plus two I bought) gives the best cooling result, but there is nothing about that in the video. Buy the way, currently I use 4 intake and 1 exhaust at the back, I find that configuration good enough.

[@theonlyredspecial]

I use 120mm fans in mine - makes perfect sense for me. Im pretty sure they don't have time to cover every possible configuration. Regardless, the negative and positive positions they used will apply to larger fans.

[@BenK12345]

I see James is building a system, I click.. that's just how it works :D

[@god-lightbulb]

How would the results change if we instead used the Silent Wings 3, non-high-speed to achieve less noise? The non-high-speed Silent Wings 3 are significantly quieter, but have less airflow.

[@KitGuruJames]

We tested with the fans running at 1200RPM so I would expect similar results with the standard Silent Wings 3 fans.

[@TheLateral18]

Hi there That's the same card i have. Does the RGB on it can be changed? Awesome cable management skills there!

[@andreleong1774]

hello, i am using the same case, with a asus maximus impact VIII mobo i realise the mobo does not have a rgb header, can i still get the case lightning to work?

[@weerdtd]

Did the Dark Rock 4 not block the 1st Ram?

[@PP-nu8kz]

Heatsink Dark rock 4 can change the fan from 135 mm. to 120 mm. Other brand fan ? Please check for me. Thank you

[@maxderman447]

Does this case come with 3-pin or 4-pin PWM fans?

[@god-lightbulb]

Would there have been a problem using RBG memory, with its higher physical profile, if the larger Dark Rock Pro 4 had been used? For more powerful CPU's such as the 3950X would you say that the Pro cooler would be advisable rather than the non-Pro version?

[@KitGuruJames]

For higher TDP processors I would go with the DRP4. Fans are adjustable so RAM height shouldn't be too much of an issue.

[@donkeysunited]

@@KitGuruJames Just check how much space the case has - if it has room for 166mm HSFs and you get a 165mm HSF and raise the fan 10mm higher, you're going to have a problem. If you have that limitation, look for a HSF with an offset fan (I got an Alpenfohn Brocken 3 for that very reason but it may not be suitable for high TDP processors).

[@ragemydream]

great work guys

[@firecrackersgreece8665]

Front fans was 140mm or 120mm?

[@bloo_110]

here’s a question, a lot of new mesh cases can come with 3 120mm front rgb fans. If i were to add an exhaust (3 in 1 exhaust), would that be too much positive pressure? (obviously have front fans lower rpm)

[@KitGuruJames]

If you adjust the RPM of the front fans it should work fine.

[@bloo_110]

James Dawson Yeah I was thinking to have low rpm on front fans and just a higher one on the back fans. Obviously tinker until it’s right I guess

[@donkeysunited]

Another factor is noise. If you can, go for 140mm fans and run them at a lower speed. Smaller fans have to spin faster which makes more noise. Larger fans can spin slower to move the same amount of air and are therefore quieter. Even better if you use PWM fans and use fan curves to tie their speeds to temperatures so they make very little noise when the PC is barely being used. But you can't go wrong with 2/3 in and 1 out.

[@rzymski1974]

Which case is better Pure Base 500 or Pure Base 500DX in terms of airflow/noise reduction? Or maybe you recommend other Pc cases at a similar price?

[@Norasthaine]

Hi, Pure Base 500DX if you look at the tests/reviews. I had already asked myself the question and the 500DX is better ventilated for the same noise. Better finish also apparently.

[@tigerbalm666]

You need to point the front lower under teh GPU! Any air hitting end of gpu will cause air vortex and heat build up.

[@miguelangeldominguezbriant9178]

How Was the noise level ? Im thinking on buy a case and other things specialy for that

[@KitGuruJames]

We didn't record the noise levels since this was an airflow and thermal performance test, noise wasnt critical. However, noise levels with the Silent Wings 3 high speed fans running at 1200 RPM were audible but I wouldnt say it was too distracting.

[@stanisawkowalski7440]

I have three Silent Wings 3 140mm and can tell you, it depends on the case. With my previous case (SilentiumPC Armis AR7 (not shit) + 0,5 mm thick best sound dampening material sides, top and front) I couldn't stand them running 1000 rpm during gaming (no headphones). With my current case (Define 7 Black Solid without any additions) sometimes I don't notice they turned from 300 to 1000 rpm when web browsing. Really - 13 kg of case works like that. Don't go airflow case (like DX) route, if you want more silence focused build. Airflow cases are better for overclocking, but dusty and noisy. What is unique about SW3 is the type of sound the create - that low I never heard from fans. And lower the sound is, harder to hear for us. That means decibel charts won't tell you much. I'm really into cases, fans and coolers (kinda niche I noticed), so if you need any advice - feel free to ask. I know the best options in any budget :)

[@privacyprivacy8206]

I have BALANCED, 3 INTAKE AND 3 EXAUST

[@gregorygkizas582]

What happens when you have a balanced airflow but with 3 front and 3 rear fans instead of 2? Is it actually that better, or 2+2 config is enough?

[@KitGuruJames]

2 intake and 2 exhaust is more than enough airflow for this system. 3 and 3 would give similar airflow and pressure but potentially lower temperature with more cool air entering and warm air leaving the case.

[@gregorygkizas582]

@@KitGuruJames I have p600s case with 3+3 and the dust filter in front gets filled in like 10 days, so I'm wondering if I should drop to 2 front fans. They are all 140mm so pretty massive airflow x3

[@KitGuruJames]

@@gregorygkizas582 you could try running with just two front intakes to see if it helps with the dust build up. Do you have the system running 24/7? That sounds like a lot of dust build up in a short time.

[@gregorygkizas582]

@@KitGuruJames No I don't run it 24/7. It's a lot of dust but at least the filter does its job well xD

[@paulvhs677]

What happens if you keep the normal airflow and put the fan, that’s on top of the case in the direction, so the airflow goes down? I’ve testet it with mine. 2 fans in the front, take air in, one in the back, takes air out and 2 on the top that take air in. CPU stays at 40 degrees, even on 4,6 GHz. (Got an I5 10600k) Does that make sense? I mean, it works but it does not fit into negative or positive pressure, can someone help me out?

[@paulvhs677]

All fans are btw silent wings 3 140mm

[@alexander10122]

2 on the front as intake 2 on the top as out 1 on the back as out Is it ok?

[@Wigglythegreat2]

I guess it will depend on if the specs of the fans. If they are all the same then I would run 3 front intake and two in rear out.

[@SuperFischboy]

in the video you´re putting 4 ram config , while in the video description you´re stating that you put only 2

[@usbsol]

Thanks, I think its a little bit of a shame to not use the included fans - they are part of making this case such a good deal. Also (imho) you should have used a Dark Rock Pro 4 (like me) and non-rgb-ram for more blackness/batman 🤘

[@GodSEndOMG]

Would being nice with testing with the HDD case in the box since many people would use 2x hdd for storage. Since the third fan infont would blow directly into the psu instead of the hdd case then is not "valid" test for those who use hdd. but great effort.

[@Zaevia]

The actual difference in pressure is very negligible doesn’t really matter.

[@Avrelivs_Gold]

You didn't give it enough positive pressure Especially for the CPU, it just didn't reach the radiators. Try more intake next time, fans closer to the MB. It works perfectly for the best case ATM -- Fractal Torrent.

[@Dyonivan]

I'm not sure why everyone is praising this video. The information that we were looking for comes at the last 20% of the video, with the rest of this (arguably too long) video being excruciatingly monotone explanations of the testing. And the results? Not even what most of us were looking to find out. I never cared about positive or negative pressure on CPU temperatures, because all the CPU needs is air flow (and this is reflected in the results considering all three temperatures were within margin of error). I wanted to see you demonstrate how much positive or negative pressure affects air intake from parts of the chassis that aren't meant to receive air. I also wanted to see ways to change pressure depending on fan configuration / RPMs.

[@knownas6217]

WAS interesting, although as with temperature positive and negative pressure without knowing the pressure gradient from inside to outside the case, can be a little meaningless. When the gradient will affect the effectiveness of cooling. As yet Pressure sensors (unlike temperature understandably as this is the critical factor) inside a case are not provided and probably may never be as the move seems to be towards water or closed loop cooling, which in my view does not offer any real functional advantage over good air cooled systems.

[@gunawansambudi720]

The title is "testing" But i didn't see any test or experiment Why?

[@xXavokx]

You pretty much build the pc I want to do. Just little changes the b550 with x570 master and the corsair ssd with aorus sdd. I was thinking for a silent black/orange build. It really is silent at normal fan situation speed?

[@fatrick9001]

I don't know why people are so concerned about dust build up when they can simply clean it every once in a while with a pressure air cannister.... People without pets in their home could opt for negative pressure and get lower temps.

[@ouki4925]

The heat output from the hardware wasn't enough to see any difference.

[@johngamble5270]

Given the setup, why a 750W power supply? Are you assuming the possibility of upgrading to more power-hungry components?

[@KitGuruJames]

The 750W power supply was used just because it was available and as you suggest it would cover future upgrades. A 650W power supply would be more than sufficient for this build too.

[@coryandrum]

BeQuiet probably would not mind if you bought the higher watt and more expensive one ; )

[@VeX-hr8yr]

Great info but why run it without filters and front panel , no one is going to replicate this at home on a daily basis.

For the testing, we ran the case without the front and top dust filter to minimise any airflow restrictions but the front panel was fitted.

[@VeX-hr8yr]

@@KitGuruJames thanks James , I'm looking to get this case as an upgrade from my s340 elite . Looks like a great case to build in. S340 always seemed a little restricted airflow wise with there front panel so I'm sure this will be better

@@VeX-hr8yr ahh the S340 Elite, i used one of those in the past, the white version. The Pure Base 500DX is a similar size as the S340 Elite but should be an improvement if you are looking for better airflow.

Don’t even bother testing all fans filled?

[@magnusnilsson9792]

Your assumptions are flawed because the top fan is angled. Your balanced is 28800cm^2 in and 24000cm^2 exhaust. total: 52800 Negative is 14400 in and 32667 out total: 47067 Positive is 38400 in and 14400 out. total: 52800 If you were to put a 140mm fan as rear exhaust on the balanced you would be closer to actual balance with 29200cm^2 out rather than 24000.

[@ivanbrasla]

actual airflow will be lesser for the intake fans because of the impedance of the grill, so you should bias your cooling setup towards having more intake fans than exhaust fans

@@ivanbrasla Exactly, filters hamper intake fans with about 50% so 2x140mm intake and 2x120mm exhaust would be 19600 in and 24000 out, even 3x120mm intake fans wouldn't be able to match those exhausts with only 21600 effectively. The top fan are even more useless as an intake only providing 33% efficiency if filtered as is appropriate.

@@magnusnilsson9792 there are other factors that had to be considered such as the other fans in the system. Both the CPU and GPU fans affect the air pressure.
