My mini NZXT H1 PC is so loud… Let’s fix it.

Since shrinking the studio’s gaming system with the NZXT H1 case everything has been going great except the level of noise. The NZXT H1 is a great case but due to it’s fan configuration it’s not always the quietest of systems so today we are going to fix that, with a little help from our friends at Noctua.

[@TechLabUK]

Big thanks to Noctua for supporting this project and saving our ears... again. Definitely check out their fans next time you are looking for some and they make some of the best quality ones.

[@GamingOnArc]

For that cooler, i would have used the stock fan under the heatsink then added a NF-A12x25 type fan on the top of the fin stack for a push pull config.

[@TechLabUK]

That's a great idea. Will take a look at it again and see what I can rig up.

[@GamingOnArc]

@@TechLabUK doing this would allow for identical cooling potential at lower fan RPMS. You could also increase the RPM’s a bit to increase cooling while still having acceptable fan noise. There should be an extra set of fan clips in that cooler kit.

[@TechLabUK]

@@GamingOnArc it’s a great idea.

[@deanos1993]

Great idea - I think I might do this if the aio pump fails. Do you think it will cool better than the stock aio?

[@johannespaschold2453]

@@deanos1993 does it have enough clearance to mount the 12x25 on top?

[@helloukw]

That's weird. I have NZXT H1 v1 and I can tweak the AIO fan from the BIOS. I modded my case by adding 2 120 mm Arctic fans on the back, outside of the case, since they align perfectly with the grid, one for the intake and top for exhaust and the system runs pretty much quiet.

[@MrKranky90]

I will do that too these days, thanks! How much cooler are your temps now?

[@helloukw]

​@@MrKranky90 Yes, its an easy mod. Not sure, but I'd say around 10 degrees or more since before was really loud and quite hot and now 7800x3d is around 42 in idle and around 60 in gaming, while being quiet. The GPU is around 69 at max TDP (150W), the same, while being quiet.

[@helloukw]

@@MrKranky90 Update on NZXT H1: I've noticed the bottom part of the case, GPU side, gets hot during long period of gaming, so I decided to use both Arctic 120 mm fans as exhaust and the temps are even better and now the whole case is cold to the touch. Now its even better dust wise, since the back doesn't have dust filter like sides do. CPU and GPU 52 - 60 degrees now during a game like Days Gone in 1440p, CPU 35 W and GPU 150 W no matter how much I play.

[@alexriley4891]

How did you manage to do this? There is no room at all for 2 extra fans in the case? Or are they outside of your case?

[@helloukw]

@@alexriley4891 I mounted them on the outside.

[@SoulRollerFIN]

Would've liked to see the noise comparison on the video. I'm definitely switching to the aircool mod once the pump fails. The PC runs quiet enough with the hot rod fan mod on the back panel though. I have 2 noctua slims back there, running at low RPM. The only thing keeping this PC a bit louder right now is the failing thermal paste. I need to figure out why it keeps failing. Maybe the AIO is not isntalled on tight enough?

[@rugby187gaming]

Yeah I'd go push/pull on that CPU cooler. If you use the stock and the Chromax, maybe double check RPM on them as may be different. I changed the brown fan on the L12 Ghost S1 Edition for a Chromax and the Chromax was a higher RPM (2000 rather than 1600 on the original). Obviously you can always balance out in BIOS if on seperate headers too if required. Nice mods though, how are the temps on the 12700K now?

[@TechLabUK]

They seem fine at the moment but haven’t pushed it too much yet. Will know once it’s getting fully used lol

[@Amaan_OW]

This is the setup I am running now. BeQuiet 140mm silent wings pro 4 at the front (exhaust) and stock noctua B9 pushing through at the bottom. The L-12S is taller than the ghost edition though, with the L-12S the top fan would have to be slim, not 25mm. I think there is clearance for 26mm worth of fan with the ghost edition as my arctic p14 would not fit right. When I am able to, I am going to replace the stock noctua fan for the A9 and move the stock B9 to the back.

[@dimitron5124]

I own this case and was considering doing the same type of thing with mine… This video is exactly what I was looking for, thanks!

[@TechLabUK]

Well worth it tbh, only issue is now I have to check to make sure fans are working because it's so silent lol

[@mikep9418]

It's a pity that it needs any modding to run quiet - NZXT really missed the ball there. However, once done it works and looks great. Well done for the video.

[@TechLabUK]

Turned our really good tbh, so quiet now. Need to tweak the curves a little hear and there but that's about it.

[@mikep9418]

@TechLabUK I used Fan Control software to produce a mixed curve for the psu fan. That way if either the cpu or gpu are under load the fan will ramp up.

[@TechLabUK]

@@mikep9418 Good idea. I will take a look into it.

[@Petri357]

Thank you! I have replaced the original NZXT H1(V1) AIO pump with the NOCTUA NH-L12S and I got way better temps 🥳

[@rickgeller6043]

You could have at least put the panels on and turned the PC on. Be kind of nice to hear a before and after the modifications.

[@TechLabUK]

It's hard to capture the exact sound, those with the system will know exactly what the modifications will do though. It's continuous windy tunnel noise to silence basically.

[@tomtran614]

Can you use the decibel noise meter and measure the noise levels after the mod?

[@MrKranky90]

@@tomtran614 No, because it is one of the worst tech channels here on yt (another channels do it all right!)

[@michaelw2263]

With the v2 the PSU is always loud even at idol. Apparently NZXT is aware of this. I changed my fans to BeQuiet fans and now all I hear is the PSU.

[@TechLabUK]

It is a little annoying tbh, NZXT should have spotted this.

[@michaelw2263]

@@TechLabUK I agree. But I guess, it's nice to have a higher wattage PSU, all things considered.

[@TechLabUK]

@@michaelw2263 True, the 750w wakes it much more useful.

[@nosajmartinez6175]

It was great to see noctua as a sponsor but that 140mm aio is way better than the air cooler selected for this video.

[@TechLabUK]

Cooling performance seems to be about the same, the air cooler is just quieter and more reliable, these 140mm NZXT AIO's are not known for life expectancy due to the pump design.

[@nosajmartinez6175]

@TechLabUK That is really surprising. I built a 12700k h1 system for a friend, delidded, and overclocked it to 5.2 all core, e cores disabled. Some burn in loads were around 220 watts, and the AIO did ok. I don't think the low profile air cooler would be able to do the same but l haven't tested that air cooler specifically. We did upgrade the stock 140 to a silent wings 4 140 high speed fan and it was noticeable.

[@akridexd3448]

Well i bought used one and the pump was dirty,after trying to clean it i couldnt get right temps so i went with termalright full copper cooler and temps are arround 65c on load,now i just need to ad few more fans for intake since the one i had is way too loud. Overall i think air cooling is much better for this case

[@MrKranky90]

No Temps or db comparison at all! And why change the whole CPU cooler for a worse model without watercooling? Why not changing only the Fan of the CPU Radiator? This Video is so sponsored, because the integrated AIO is much better and cooler..

[@TechLabUK]

These AIO Coolers are commonly known to fail.

[@chris_hertford]

Nice upgrades!

[@TechLabUK]

Came out really well and it is next to silent so real happy with it.

[@adamblack1908]

I just bought this case and it broke the bank, maybe I'll do this someday.

[@TechLabUK]

It works perfectly fine without any mods. I just like silent PCs and wanted to tinker with it :D

[@akumatie]

Looking good, can't go wrong with noctua

[@TechLabUK]

Noctua power 🚀

[@TruSuCiO23]

How are the temps now with all the changes? I am thinking about doing this change but i had already modded by having 3 notcua fans in the back for more exhaust so maybe might just do away with the whole nzxt fan on top.

[@TechLabUK]

Temps are totally fine tbh, no issues at all. Was worried still at the beginning because the 12700K get's really hot but in this setup no hotter than a normal case tbh

[@TruSuCiO23]

@@TechLabUK that's great, definitely going to do this but I have a 5800x so might check to see which cpu coolers noctua has works great for that chip and in this case. My only issue now seems that I do not have enough fan headers in my motherboard to do the PSU fan swap 😭

[@pkymalainen]

how do you remove the smart controller??

[@TechLabUK]

It basically rotates up and then pulls out. Look at where the hinges are and they will line up with a cap.

[@thomask1424]

You could swap the PSU for one with a switch (a more expensive option, of course). Get one where the plug is in the same place, like the Lian Li.

[@Wolfoffreedom111]

You can control 92mm fan speed and 140mm fan of Aio in Cam software wtf 🤦

[@TechLabUK]

Yes you can but they are not the noisy fans in the system. The PSU one being full speed all the time is.

[@Wolfoffreedom111]

@@TechLabUK It is strange that it runs full speed. I just bought one for 135€ so I can’t complain.

[@TechLabUK]

@@Wolfoffreedom111 It is strange, no idea why they made it do this. As a normal machine it might be ok but in our studio we need things silent because of recording. I saw a lot of people saying they were loud so did this to make sure it stayed silent.

[@TB64_NVME]

whats a good CPU for 1080 ti again please?

[@JBrinx18]

AMD Ryzen R5 5600 will do great. In fact a 5500 would be just fine. If you want to upgrade just the GPU in the next two years, I might recommend the 7600 to give you a 20% CPU boost

[@TB64_NVME]

is 7600 am4?

[@JBrinx18]

​@@TB64_NVMEno, it's AM5. 5500/5600 is AM4 though

[@mikep9418]

@@JBrinx18 I'd recommend the 3600 over the 5500 if you can pick one up cheap enough as it has more cache and is PCIe 4 instead of PCIe 3. However, the 5600 would be even better, as you say.

[@TB64_NVME]

4070 Ti is a 1440p GPU right?

[@TechLabUK]

Yup.

[@JBrinx18]

It's pretty much a 3090ti for older games (4k+), a little kneecapped with the newer titles with high textures

[@Markjonathan]

Just ordered the PSU fan, that noise on Idle has been driving me nuts since I got the case last year! Is it not possible to just divert the existing fan directly to the motherboard? I'm assuming the PSU is the same on the V2...

[@TechLabUK]

Yeah, seems to be the same fan on the V2 or close to it. You can't re-direct the existing one to the motherboard as it only has two wires and no header connection.

[@Markjonathan]

@TechLabUK since watching your video all I can hear is my fan 🤣 it's driving me insane and I have to take an exam on it tomorrow before i can make the swap!

[@TechLabUK]

@@Markjonathan TBH I only noticed it after one of our subscribers mentioned it in the comments on the build I did in the case and once it was said it was all I could hear so I quickly contacted our Noctua rep who fully understood lol

[@Markjonathan]

@TechLabUK I've just seen that I think your amazon link is linked to the wrong fan for the psu? The link is for the 25mm depth one not the 14mm? Sorry if I'm wrong.

[@TechLabUK]

@@Markjonathan They seem correct when I click on them?

[@egomate]

Amazing! Will try to do the same with mine! Thank you!

[@TechLabUK]

It's been silent ever since and is still running great.

[@adeelio]

For an affordable option to tackle the main noise culprit, could you not just do the PSU cable extension mod using the existing fan and connect it to an available M/B FAN pin?

[@TechLabUK]

I am sure there are some forms of adaptor extensions for them but the fans in these only use two wires so wont get any form of PWM signals to be controlled from a motherboard header.

[@adeelio]

@@TechLabUK ah i see, so a PWM fan replacement is needed at the very least

[@SimplyAirborneRealYT]

I have a question what’s the maximum fans u can fit in there ?

[@TechLabUK]

By standard the ones I change in the video. Not great tbh but have seen people mod them to take more.

[@angrybobdylan]

Thanks for this video! I just did this to my h1, but I skipped the power supply mod because I'm not sure how to set the fan curve. What temperature signal did you use? I don't see any option in bios to adjust the fan speed based on the psu temperature.

[@TechLabUK]

I used the system temp and then made it more aggressive. The motherboard won't know what temp the PSU is because there's no sensor to read so an aggressive curve on system usually works fine.

[@angrybobdylan]

@@TechLabUK Awesome, thanks so much!

[@rhysbooker]

If you swap the fan to the outside as you did, was the low profile RAM still a requirement?

[@TechLabUK]

You can get away with another 15/16mm on top of the ram I used with the fan on the outside.

[@rhysbooker]

Great, thanks! Turns out my mobo won't fit the L12S, so looks like it'll be L9x65 instead.... Hoping to fit the second fan as well for that push/pull as someone else suggested

[@Amaan_OW]

if u were to use a 2 pin adapter for the new PSU fan how would it sound? Am considering doing that...

[@TechLabUK]

With a Nocua fan I suspect it will sound fine tbh. I have umped that little fan up to 100% and it's not as loud as the NZXT one so should be fine.

[@Amaan_OW]

@@TechLabUK Good to hear, thanks. I was a little worried considering that model goes up to 2500 RPM. I will try the swap and update here.

[@TechLabUK]

@@Amaan_OW If you are worried you can also install a Noctua Noise Adaptor, it will basically lower the 2500 RM down and you can get them in different sizes.

[@Amaan_OW]

@@TechLabUK That is a good idea actually, I have a spare from my CPU cooler. Is there any chance you could reply with the stock fan's model name? Or even the specs... I like quiet but I want to take caution to not let my PSU overheat either. The H1 website doesn't list the specs of the fan beyond the size.

[@Amaan_OW]

@@TechLabUK Also, does the stock fan have a micro or mini 2-pin connector?
