Watercooling pumps getting hot? Just watercool them...

[@suhbatshugan3721]

P - The P is Silent I know this comment is a joke and quirky but that's what pumps actually do. they dump heat into the loop.

[@JamesRobinson01]

yo I heard you like water cooling so I water-cooled you a water-cooling loop which is water-cooling the water-cooling loop water-cooling your water-cooling loop

[@Scoobydcs]

for that setup to work properly you need to n2o cool the whole loop!

[@Xyphren]

Jay, it looks like the Housing touching the PCB was the issue. NOT the pinched wires. so metal housing grounded a contact point either on the PCB or on the power leads into the PCB and then that touched something somewhere else on the PCB.... a Short on the power input wires would not have damaged the Pump... Electrical theory says: Path of least resistance means the input power to the metal case to the PCB created a melted IC

[@kraylthunderhorn7891]

With regard to your Green dye making the tubes Red: some organic dyes are sensitive to their environment. A green dye may be green when it is in an aqueous environment (water) but may be red when in a hydrophobic environment (like absorbed into the plastic tubing). I work in a lab for instance and we have a common dye that we use for protein gel staining. It is dark red when completely dry or dissolved in oil, but turns bright blue when in water. Just a thought.

[@ianciti]

was hoping someone would offer an answer on that. thank you.

[@GotrekGurninsson]

Fierce grape gatorade... made your poo neon green... lol

[@thealmightytoad117]

It's "tube burn". You see it inside older hot tubs. Hot water flowing against the plastic for long periods of time will cause a dark red/brownish stain. The purple color probably has something to do with the green dye...

[@YoloVib3s]

Jay why not grab a dremmel or file and make the opening bigger to release the pressure on the wires?

[@Jayztwocents]

I actually did that on the plastic one, but I will do that on the metal one and reuse it later. Just didnt have the right size bit.

[@YoloVib3s]

JayzTwoCents gotcha .... this video was very insightful though. I always love getting that notification of a new upload from any of my Cali tubers.

[@squatchhammer7215]

I'm surprised they didnt have a rubber grommet to fit that section where the wires are supposed to go.

[@An9eL_C]

Was about to post the same reply till I read yours... "Fortunately I have a ton of these pumps laying around" damn that hurts...

[@Xyphren]

JAY, take a better look at that Housing before you do. the power leads may be making contact at the solider points to the casing this may be the cause of the damage to the electronics. pinched wires that are fully sheathed wont cause an issue IF they have not broken the sheathing.. your issue seems to lie in that metal housing and the contact points that are causing a short.. there may even be a chance of this happening again... if the wires were shorted at that Pinch point, the PSU would have kicked off when it detected a short. Remember: Electricity wants the path of least resistance.

[@gottagift]

At times, my experience with fire protection systems involves the use of anti-freeze. When the piping is composed of Cpvc, we MUST use glycerine based antifreeze as opposed to polypropylene glycol.

[@somethingstuff8946]

If someone's already mentioned this, then ignore me. Pinched wires would not create a short, it creates high resistance or even possibly an open circuit if the wires inside the sheathing were pinched hard enough to cut them . A short would be if the wires were exposed and contacted a surface that's connected to ground or other exposed wires. Either way, love the vids, been out of the pc building game for over a decade and you've helped me get back up to speed on things!

[@Hitokiri_Ace]

Hopefully he addresses this, because you are correct. Since the wire is stranded as well, the likelihood of it causing an open (aka breaking all the strands) is highly unlikely. (The old pump could have, after many bends back and forth.. the new pump however.. nah..) My guess is that the metal chassis cover itself was shorting to the PCB. Glad someone else pointed this out too. :)

[@Mythricia1988]

Yeah, definitively not the cables. Hard to tell if the chassis could be shorting the solder points or something on the PCB, but to me it almost looked like fluid damage. I've seen and repaired water pumps (not PC cooling ones) with water damage before, and it looks a lot like that. But that would be weird, if it was water, the blue smoke would have escaped long ago - I'm thinking a short was causing the original problem, and then during disassembly a tiny water droplet made its way onto the PCB and dealt the deathblow. Else it'd been smelling magic smoke all day in that room.

"Dammit my pump died... Alright I guess I'll have to use one of the other 30 Pcs I have laying around." - Jay

[@HappyfoxBiz]

Jayz, here's a really good tip for you if you are wanting custom antifreeze. Get yourself some ethylene glycol (but keep it locked away, seriously...) Ethylene glycol is clear like water, you colour it with dyes as much as you like then you fill it with demineralized/distilled water 60% water to 40% ethylene glycol. If you don't do the mix in that ratio, the ethylene glycol will boil faster than water (it actually does...) Now, be sure to shake, pour and clean up thoroughly, if it's clear, treat it like ethylene glycol and wipe it down with all purpose cleaner. Enjoy your custom antifreeze build

[@zephyr424]

Your comment is a good one and made me look into this further. Water boils at 99.3 °C, Ethylene Glycol at 198 °C. A 1:1 solution of ethylene glycol and water boils at 129 °C. Ethylene glycol is completely miscible with water in all proportions. Therefore, once mixed, the glycol will not separate from the water, ever.

[@shodid]

you're a genius. i have a ddc pump and turned my computer on on monday... heard my fans going nuts and checked my temps. my CPU was up to 55-60c. checked the pump and sure enough, the pump was dead so i ordered a d5 pump the next day. today, i watched your video and thought i'd play around with the wiring and.... voila! thank you sir!!!

You learn the hard way so we don't have to :P. I'm not a water cooling guy, but years of Jay and I'm a lot more knowledgeable than I was 2 years ago. Thank you for always being transparent about your products, findings, faults, etc. You're humble enough to admit a wrong and thrive to make it right or find a way to fix it. I've always enjoyed that about your videos. Honesty is the best policy, because you know we'll find out otherwise! lol. Thanks again, Jay.

[@genemetz24]

I love how you grow along with your videos. The end was breathtaking. I was not expecting this level of passion. Deeply appreciate that you take the time and effort to share it with me and all of us that watch your videos. Do what you love to and we will keep enjoying the ride.

[@EvilJ069]

Uh, how would that cause a short when the wire insulation wasn't punctured?

[@jckf]

Yeah, the conclusion seems a bit flawed, although there is obvious there was a short when you see the fried electronics. I'm thinking the exposed part of the wire, where it meets the PCB, was touching the casing, which in turn was grounded.

[@EvilJ069]

+Jim C K Flaten That was my thinking as well

[@jckf]

That would cause heat at the break, not burn out an internal component.

[@madjimms]

Not true Jim C K Flaten, Super low voltage can indeed damage components.

[@jckf]

The problem there is not the voltage itself, but the increased current draw to meet the power requirements of the components. If this was the case, there would be even more heat developed at this hypothetical break in the wire.

[@vencibushy]

I have no idea why people keep buying those DDC pump heatsinks. What you're trying to achieve is to transfer the heat from the top layer of the PCB(where the hot components are) through 1.5mm of FR4 laminate which has thermal conductivity of around 0.25 W/mK. Any electronics engineer would tell you that this is complete and utter fail and bullshit. If you want to have your pump cool and long lasting just run it at 9V. The start-up voltage is around 8V so 9V is completely fine. It will draw around 5W @ 9V.

[@Mythricia1988]

This.

[@NVMDSTEvil]

better yet let the PCB and components breathe by making some air holes in the casing

EVGA FTW2 and SC2 1070 and 1080 is my guess.

[@KaineTube]

Awesome to see the humble ddc getting some love. I've been using one for years, and it's been a super reliable little trooper. They can punch well above their weight in pressure and are very quiet. The new impeller design is interesting, at first glance it looks like it might be designed to work better with a low restriction top inlet like in this setup, rather than the stock parallel barb configuration.

[@Mythricia1988]

That impeller looks a lot like the one on a D5, with the shrouded "top" surface.

[@stykytte]

Jay, when you swap the impellers over between pumps, you should do a "do what I say not as I do" too. Dropping the impeller onto the bearing can damage them, I learned the hard way they can chip real easily.

[@Xedhadeaus]

You ever thought of being a science teacher? you sound just like one... Like you probably know what's wrong, but just love your job so much that you can tease around what you think for an extended amount of time. And still keep everyone entertained.

[@OrbiterElectronics]

Coolant shouldn't effect the electronics even if it did escape past the seal as the PCB and components are covered with a conformal coating which protects them.

[@JaimeRosario884]

well, its 50% and 50% water, so it would affect electronics if they werent coated, and maybe the coolant and even the water itself can wear out the coating

[@lachlan6497]

Water cooling with milk. Yum

[@anythingwithplanes]

Jay. Just for fun. I have a thermal take water 2.0. The rad spring a leak so I soldered it shut. The loop lost almost all the water and had some growth in it. I replaced the liquid and cleaned everything. It now is running windshield washer fluid. I've gotten better results than with the stock liquid. Funny thing is they smelled the same...

[@mattsmechanicalssi5833]

@JayzTwoCents Two things 1: Anti-freeze/coolant is more viscous than water. A 50/50 mix might be to hard on the pump. 2: Anti-freeze is very electrically conductive. Much more than water. Thanks, Matt PS - Like the vid!

Cool video Jay. I love the purple, It's a very similar colour to what I'm running in my rig at the moment. Although I think you should have put the antifreeze back in because I'm interested to see how long it can be in there before it actually does cause some damage.

[@FawziBreidi]

[@rhaacke]

Some of the old Cray supercomputers used to be filled with flourinert, a nonconductive clear liquid. There was even a "waterfall" in the middle of them. My jaw dropped when I first walked into the computer room at Lawrence Livermore and I saw the waterfall in the middle of the computer. It dropped even further when I saw that the entire interior of the Cray, which was covered in clear plastic, was also full of the fluid.

Nathaniel Smith It was never made for PC watercooling, it is a pump from a German company. They pretty much made it as good as it gets with their performance/silence/power usage for its size so we still use it today

[@nazarethrift1019]

As for the antifreeze debate, I built my first water cooled system when Age of Conan came out. When I asked the tech guy about the coolant, he told me then it was just 50% distilled water and 50% antifreeze, I have been using it ever since. 5 years ago I rebuilt the system using the same cooling system save the reservoir, as I cracked the old one by over tightening a fitting. It still has the pump CPU block, radiator and lines with no signs of degradation.

[@larrygall5831]

[@johnsmith-yy7xf]

2 notes. 1: Love you have a z, I've got a 280z and 300z. 2: Brother did a clear see through piping for his 68 camaro's coolant system. Over time, the lines turned a redish brown, and then full brown. Not sure what type of lines he used though since it was about 15 years ago.

[@TheBabbage78]

That's why I just stick to a high quality air cooler, the only point of failure is the fan and is usually very easy to replace.

[@Hitokiri_Ace]

.. not to mention you still have a good deal of heat capacity, even if the fan dies. Not so hard on equipment that relies on it.

[@TheKratoKiller]

Just as easy to replace as a pump with a dodgy housing

[@Hitokiri_Ace]

How much cooling does a dead pump offer, compared to an air cooler with a dead fan? : |

[@somedude2492]

John Dowty a normal disipator does not work as a passive dissipator, the same as a dead pump.

[@NECRONEZUM]

That's why I'm scared to do a custom water loop. Do we at least have warranty if something like this happens?

[@TheAtqthe30th]

NECRONEZUM usually not, They'll more than likely blame you if something goes wrong. Had 4 QD fittings from Koolance completely fail in under 6 months and wouldn't honor it

[@TheAtqthe30th]

Arrow I know some people like to lower the rpm of the pump to lower the noise of it.

[@link_jumper2632]

Arrow ever heard of overclocking?

[@seb8276]

Link_Jumper Ever heard of beefy air coolers or AIO liquid coolers...

[@link_jumper2632]

Yes I have but, with a custom loop you will get better temps so, potentially more headroom for overclocking. Which could be a performance benefit making Arrow's statement not true.

[@JustanOlGuy]

Jay, I ran Rhogard boiler antifreeze in my last custom loop. It actually worked really well. I had it in it for over a year with no sludge build up. It had aluminum core so this was my best choice. This was on an old Q6600, EVGA 680 MB with 3 way EVGA 8800 Ultra's.

[@anthonyc4033]

[@joshuacox1046]

that little over sight by the builder would kind of piss me off a little. i didnt think it was the pinch part i was looking at the unprotected solder connection touching the bottom corner of the lower housing. i hope there is some kind of warning telling you that the pump is malfunctioning other wise that could have been much worst.

[@Hitokiri_Ace]

I agree with your diagnosis. The pinch wouldn't short unless it bares the wire. The housing was likely shorting to the PCB/solder points.

[@MrScart35]

this is the correct answer

[@joshuacox1046]

Not sure why jay would think pinching a wire would cause a short. No ones perfect right? Looked like the solder connections on the one he smoked were a little larger. I think that's why the second one actually burned out.

[@jesondag]

I ran antifreeze for over 3 years on a thermaltake cheap pump, and it was alright. Just one piece of anecdotal evidence, but just tossing that out there.

[@matthewsykes4814]

Quick tip with o-ring seals, grease it. Not crazy like packing a bearing but a bit of light duty grease in the o-ring bed keeps the seal in place and adds a bit of extra sealant. Or silicone sealant

[@VladPayne]

I had a few pump fails and a leaking rad after a few years of service. Pumps were DDC as well and they always die that way, it's the "bearing" wearing off or the coil no longer outputs the power needed to start the impeller. Loosing up the top works sometimes. the When I had to replace the motherboard + cpu - gone Sandy Bridge to Skylake, I decided that enough is enough and went full air from full water. Never regret it. WC is overrated IMO. CPU temps even dropped, as I had a single loop and that GTX 1080 was a killer on overall water temps. The GPU got 10c warmer, but still below 73c with full OC (soft mod + hw mod).

[@sienile]

2 minutes with a rotary tool, problem solved.

[@Arek_R.]

Or small piece of capton tape.

[@taiiat0]

+Arek R. if pressure from low clearances is the problem, pray tell, how would adding tape to the area - which increases the physical size of everything - solve the problem?????

[@TheFallenAngel13524]

because the pinched wires aren't the problem. If the strands broke from pinching they'd just stop working but wouldn't jump through insulation to another wire and short out. The sides of that metal cover aren't insulated. couple that with the stupid amount of insulation missing off the wires at the solder point and you get shorting to the case via exposed wires. Adding tape to the exposed wires or case would insulate and stop shorting.

[@taiiat0]

Alex Jennings the exposed ends could be the cause, but if the issue is around the pinched region, more material isn't going to help.

[@Arek_R.]

The problem is that wires are shorted by metal case and adding hard insulating tape would protect from shorting the wires.

[@theripper121]

Ali Abbas Two quite contradictory statements.

[@Yeahboii1]

a lot of people see a question in the title as clickbate, I believe this stems form them noticing the link between questions and open ended statements and clickbate videos/articles and somewhere along the lines they come to the conclusion that all title with questions are clickbate

[@RetroBoxRoom]

I'm not saying it's not the pinching causing the problem - but it doesn't seem a clever design to have bare solder points so close to a metal case and not have at some Kapton tape on them. Especially on something that has moisture so close by. I wonder if there was direct contact after a ding across the bottom or some condensation, after being put in the garage. It all depends on the clearance. Either way that's one hell of design flaw for the pinching it does do, and having exposed solder points like that.

[@Intrepid17011]

That's cool about the pumps and all but I just wanna say I'm loving the new purple on the wetbench.

[@bragielsbagels]

[@Saiyamoto42]

Jay, I actually ran into almost this exact problem once. I fried a DDC pump I had due to my own negligence, so I ordered a replacement PCB for it from Hong Kong. Soldered everything up, it worked great until I added the PWM circuit to it, at which point the Alphacool housing shorted something out and fried my second circuit board lol. I have D5 and Jingway pumps in my rigs now...

[@djad332104]

there's no short in your pump. aquarium pumps work the same way, just blades on a magnet that spin when it has power. I've notice my pumps stop pumping water, i take out the pump while it's still connected, tap the blades and it's starts spinning again. doesn't take much to keep it from spinning, just need to tap it to get it back on the sweet spot of the magnetic cycle. Your second pump looks toasty......... Fan of the channel. Thanks for the great information and recommendations you've given

[@ijd92123321]

is the metal case plastic on the inside. because if not maybe one of the traces or solder joints is shorting on the metal case.

[@ptock2]

Really enjoying the B roll footage. I know it is extra work but it is greatly appreciated.

[@tytechguy]

Hey Jay, I know this video is a bit old now but I just got a chance to watch it. I have ran DDC's in my setup for a long time and I have had major issues with them all D5's included. However, I know what your issue was to your pump problem. I had them exact same thing happen to me a few times. What happens is is if you use certain coolants (your antifreeze would do this too I'd guess) the inside of the rotor where it makes contact on the ceramic ball gets a buildup of hard crusty stuff on it and basically seizes the rotor up and it won't spin. The pump doesn't have enough power to start. It will do what yours did and try to spin up but can't due to the aforementioned problem. I take a small pick and a bright light and turn the rotor upside down and scrape the junk out of the inside where the plastic sits on the ceramic ball. If you would have looked my guess is you'd have saw exactly what I am talking about. Once I do this I clean it good with alcohol and Q-tip. reassemble and mine work flawless every time. I have to do this it seems whenever I run different coolants. I ran ThermalTake's shitty coolant once and it did this really bad. Even happened with Mayhem's. However, I've been running Primochill's new concentrate and I have yet to have an issue. I guess I should also mention my pumps run 24/7 and are powered by my 2 Aquaero 6XT's. Hope this helped you out man. Rock on with the Vid's! PS. I have a couple pics of the inside of my rotor's before cleaning if your interested

that's a sick looking setup you got there ... damn, great job ... purple tones work well with almost anything !

I'm using 10% universal green antifreeze as a corrosion inhibitor. It's been running for a year straight with NO issues. D5 pump in an xspc dual drive-bay reservoir with a 240 x 60mm rad and a 240mm x 35mm rad through a Koolance 380a water block. Run it with Vinyl soft tubing and aside from a heat kink I have had ZERO issues.

A bit of a 80's vibe at the end. Even the test bench entered a Prince phase.

7:06 it just made me shiver a lot when that turn on while dry

[@johncox9660]

Wow I picked your chan on the reck of an other tuber I like and have no idea what you said or what you do but somehow I still found your vid entertaining . you are clearly a gifted presenter.so good on ya. thanks for posting .

Open Faced vs Closed face impellers: The primary benefit to open faced is in applications that tend to clog. We used them for coolant pumps in machining due to small metal chips being introduced to the coolant reservoir. Another advantage is you can adjust them for optimal flow. The adjustment is the pump distance between the open faced impeller and the opposite facing surface. This is mostly for adjusting the recirculation, flow rate and coolant temp. Closed face are useful in just about any application that aren't prone to clogging. Advantages are reduced recirculation with in the pump housing so they tend to run cooler. They are ideal for volatile liquids. I don't believe making adjustments to the open faced configuration is possible or advantages so either if fine. The only issue with the close faced I could see is with the viscosity of the coolant as a thicker coolant would be slightly restricted in the close faced impeller. But we are talking 100% antifreeze and this is not your setup.

Honest question, why do you use the ddc instead of the d5?

[@Lordn_HighMaster]

Dremel the gap wider and put a non conductive thermal pad on the bottom the solder points could be shorting out on the metal.

Your all good with the rubber o-rings. Engine coolant runs through rubber hoses in every automobile ever manufactured. And their reservoirs are made of plastic too, although probably not glychol based. One thing I would recommend. Automobiles have very powerful pumps that move the engine coolant, where as your little, tiny pump is hardly a fraction of the power. Even a 50/50 mixture of coolant is kinda thick. I would recommend thinning that mixture down as well, say 25% coolant, 75% water. Also, I believe there are some engine coolant additives that do not contain glychol. Just check out all the stuff on the shelf and research the ingredients if they're not listed.....cheers!

Kinda related, Jay. I have a DDC pump. For some reason one day it stopped working on system power up. If I gave the pump a hard tap/"shocked" it, it would then start pumping. I took it apart, saw nothing wrong, re-assembled, and it's been fine ever since lol

[@KaptainChaos999]

yep my next build is gonna be a test bench build just love the way it looks

[@Myserieden]

Jay, I just wanted to give you some love. Your always consistent with your quality, funny, and are informative. Keep up the great work. Wanted to mention the smell of electronics reminds me of cheap pancake syrup that's been sitting out all day. It's this weird sweet smell.

My pump did the same. Found it was due to the pump housing having scratches where the bowl under the impeller was running. It was sticking to the sides before it started and put too much load on the impeller to let it begin spinning. Sometimes could get it to work by inverting the entire computer and letting it start up, the weight of all the water on the impeller combined with the scratches on the housing was too much resistance.

Never a failure, always a lesson learned.

[@INeedMoarLow]

between you and hardware Canucks, b roll got me feeling some type of way!

[@samazza453]

This Is my 4th year i have been watching your videos .. I have never been so loyal to any youtuber that much but no regret..
