Hi everyone, after many years of custom builds with AIOs, I'm finally jumping into a custom loop because I got an EVGA notify queue pop for one of the 3090s with the hydro copper block preinstalled. Yesterday I transferred my build into a Meshify 2 XL so I'd have more room for the loop and rads. I'll also be cooling the 9900k in the system. With the case I have, I understand that I can run a thick 420 rad on the top or front but not both at the same time. You can however run a 360 rad on the front and a 420 on the top, which is what I think I'll go for. There's the ability to mount a 280 on the bottom in the PSU shroud but it's really pretty crowded down there and I don't think it's a great option. There's also the 120/140 rear exhaust fan area, obviously a 140 rad isn't going to be life changing but I'm wondering if it's worth just doing anyways since I'll be using soft tubing and it doesn't seem very hard or expensive to add. Here's a photo of the case now. Just a stock photo of the case. So I'm appealing to the thread's expertise. I've always watched some content around water cooling and had a couple friends do it but really a long time ago. Is EKWB still the go-to? I'm in Canada and their local distributors are out of stock on everything and probably won't restock for months. I'm paying 15-20% duty charge on anything imported to Canada from the states. A summary of my questions The things I'm cooling: 9900k (overclocked) 3090 XC3 Ultra Hydro Copper (overclocked)
Any input is welcome. e: I'm thinking I should buy this kit from ekwb which comes with everything needed for a CPU loop and the 360 rad for the front of the case, and add the EK-CoolStream CE 420 rad for the top + the required fittings. Good idea? That kit comes with enough concentrate to make 1L of coolant. Should that be enough? e: Playing with mocking up components. Does this make sense? e2: if anyone wants to draw me a loop feel free: VelociBacon fucked around with this message at 01:37 on Jan 9, 2022 |

BurritoJustice posted:EK is ok, but their QC is a bit spotty and you pay for the name. Thanks. I should have mentioned that I'm based in Canada so it's hard to find a lot of this stuff. HWLabs is on our amazon.ca but nothing in 420 seems to be on there. I filled a cart on EKWB tonight and then was hit with 80 bucks shipping on top of the 20% duty I'd have to pay, which kinda made me hesitate. I wasn't expecting to have to pay what now comes to 800CAD to set up watercooling. Kinda don't know what to do now, my cart is still full so maybe I'll sleep on it. The Canadian distributor is canadacomputers which is one of the least useful businesses in this space.

BurritoJustice posted:I really would look at 480 instead of 420, it's more total raddage and 140mm fans kinda suck right now (no 140x25 or T30-140) Thanks, I can't fit 2x 480s in my case and I don't mind the 140mm noctua offerings already in my PC. It's really overkill anyways since I only have a 9900k and single 3090 in the loop. I could probably get away with one 360. I looked around at that page but couldn't find what I was looking for. Here's the list but I just put the order through (I double checked it with a couple people already): List: I'll flush the rads out aggressively

Indiana_Krom posted:Want to throw in I have a 9900K (stock except unlimited turbo power) and a EVGA 3080 Ti FTW3 (also stock) on a custom EKWB loop with only a single 420 radiator up top. It works fine, ~500w load gaming, max coolant temperature in a comfortable room is about 43C which translates to ~52C GPU, ~60C CPU. The CPU just sits at 4.7 all core turbo forever when gaming, and the GPU settles around 1950-1965 MHz boost forever. Two radiators are not strictly necessary, although having a second one wont hurt anything, it just may not actually help by a measurable amount. Interesting, I never thought to use a plug like that but it makes a lot of sense. Does everyone use BIOS settings to control their pumps and fans or do you use software for the pump?

I already actually have a full complement of noctua 140s so I should be alright. I like the arctic stuff though. Do you guys vary your pump speed in BIOS as well? If not, where do you leave it set to in terms of PWM? VelociBacon fucked around with this message at 21:00 on Jan 9, 2022 |

Indiana_Krom posted:I run my pump at 35% PWM (~1875 RPM). Its a D5, they are insanely fast at 100% which is entirely unnecessary and excessive. Less wear and tear plus it renders it totally inaudible. I can override to 100% with some fan control software, but multiple tests checking it between 35% and 100% showed no observable difference in load temperatures on either the CPU or the GPU. Fast enough is fast enough. Yeah I kinda plan on just setting it to 40% at first, although I think mine is a DDC pump?

I can have the store do installation, but I just read the first page of this thread and the last two pages of this thread and I understood nothing and now it's kinda making me scared. You almost certainly don't need water cooling, I don't know where to start and I bet 4-5 other goons are writing and erasing replies right now because it's one of those like... yeah. There's so much here but yes you were upsold on something that is going to be an expensive hassle for you that almost guarantees future expensive headaches down the line. Why do you think you need water cooling? What problem are you solving? So water cooling isn't really 'better' than not water cooling, especially if you're the kind of person who doesn't know anything about it. All of us here are overclocking, spending $30 per fan, checking our temps and all that kind of thing. We're spending hours and hours and hours tinkering with stuff to get an extra 4-5%. The bottom line is that air coolers are 100% fine and can absolutely have that system running at peak performance. If THEIR OWN PREBUILT can't cool itself (it almost certainly can) you should be asking for a refund and not giving them more money...

Hey so I posted awhile ago about my build, it's a 9900k and 3090, with two 420mm rads. I've really been waffling on orientation of the fans on the rads, which will be front and top. I've always had my rads exhausting to the outside of the case, but I worry if I do that with this setup I'll have a pretty serious negative pressure/dust issue in the case. Here's the mockup again but with the non-radiator fan locations marked in purple, and to clarify, the basement plate above where the two bottom fans are will be removed anyways for the radiator so there's nothing really blocking them: So if I set the rads up as exhausts, there are 3 140mm fan locations available for intakes. So I would have like... 6 exhaust fans and 3 intake fans. Even given that the exhaust fans are pushing through radiators, and won't need to be ran very fast due to the amount of radiator I'm running, and I could run the three intake fans pretty high speed without hearing them (Noctua), it just feels like I'll still be negative pressure. If I set it up so air is being pulled through the rads into the case, I only really have one good exhaust fan option, the rear top one. The two fans in the basement area will not really be getting a lot of hot air and probably wouldn't be great as exhausts. I also don't love the idea of keeping every single component in the case warmer than necessary, especially as I still have two HDDs in there. What would you do and why? e: All the fan locations are filtered, even the back 140mm fan has a filter.

BurritoJustice posted:Personally, I would go front intake, top exhaust on the radiators, then just gave the rear 140 on intake. The bottom two slots will just mess with the flow, I feel. You'll also run into space issues with the max size rads and a decent PSU trying to fit bottom fans. I thought about this but thinking about the hot air from the front rad going right up into the top rad makes me feel bad + gross. I agree that the bottom fan location kinda sucks. You might find it interesting, I use the barometer in my S9+ to check things like the pressure level inside negative/positive pressure room in the hospital. It's a sensitive enough ... sensor that just raising the phone from the floor to the level of a desk changes the pressure. I put the phone inside my case and looked at it through the panel and basically I'm dumb as hell because the PC case has all sorts of areas where air flows in and out to reach pressure equilibrium. So I guess if I was really curious I'd light a shishkabob stick and blow it out and watch what that smoke does when I move it around the exterior of the case. e: I should also add that the case can take bigger rads, I'm using 420mm rads but it can actually take 480mm rads so there's a fair bit of room to move things around.

https://i.imgur.com/9gzLVNx.mp4 Hope the link works, I'm on my phone in bed exhausted after building the custom loop for the last 4-5 hours. (The PC isn't turned on during that video, just powering the fan hub with a spare PSU, I guess the fan hub feeds back into the mobo somewhere, it's a fractal thing) I took my time and had some dinner and cat petting in there but it definitely took longer than I expected, but super fun. Took at least an hour just removing the existing stuff and swapping stock fans back into the AIOs, putting the old GPU into a box (2080 to hybrid --> 3090), trying different rad/pump configurations, learning how to use the fittings, etc. Total loop volume is around 1.5L with the two extra thicc 420 rads and 250 res. Still have to wire the pump and fans properly now that I've more or less bled the system, and make the fan curves. And add a thermocouple to monitor ambient temps since those rads are both intakes. Oh yeah gotta add an exhaust fan too actually. Anyone have a decent fan curve based on coolant temperature that they want to share? I wonder how quiet I can run it with this much radiator.

Double posting a couple days later to show the completed build. Thanks to everyone in the thread who contributed their experience and knowledge to help me along with the build. Happy with it. I have my fan curves set up so the pump is at steady state 65% speed (I didn't appreciate any differences from 50% to 100% speed and it's audible over 70%), and the radiator fans spin up to keep max load coolant temps at 40C. Playing God of War in 4k with everything maxed (and DLSS on quality) gives me ~90fps and the GPU never goes over 55C. CPU is spikey by nature (9900k) but I was able to drop my vCore a tiny bit after the custom loop and that's also working really well.

AutismVaccine posted:Set your D5 at max 35% and your fans to 600rpm or so. Should be plenty as long your components arent too restrictive I'm running a 'EK-Classic Pump Reservoir 160 SPC' which is a PWM driven DDC pump. I get up to around 500-550w and yeah temps on the gpu never break 60, the cpu temps under synthetic tests can still spike basically to tjmax since it's bottlenecked by the solder TIM on my 9900k. Loop temps max at 40C.

It's doable... but I would probably get an AIO for the cpu and leave the GPU air cooled. I don't think you have the radiator space for a decent cooling solution for both so why add complexity with no benefit.

Shipping was fast and no issues with anything from them. I have to say, it sounds like if you just undervolt your GPU you'd solve every problem you're experiencing. You might not even lose performance and I'm guessing actually that you'd gain FPS over what you're limiting to and have a quieter card. I'm no expert on undervolting but if you look around online there are some great resources.

I’m in Toronto and have a trip to Ottawa planned for next month, so that could work out well. You basically just look at the case you're using and see what will fit. If you look at my posts on this thread you'll see I screenshot a pic of the inside of my case and scribbled on that in mspaint to figure out what I'd be doing. Sounds like you might be compromised on case cooling/airflow if your GPU is that hot at 50% load. Is the GPU getting up to 80c+ when you hear fans? I'd try to isolate exactly which fans you're hearing. Lots of people have their case fans on curves attached to CPU temps and it's not a great idea, for example.

Subjunctive posted:I got Argus Monitor so that I could anchor fans against the worse of CPU/GPU temps, but I might not have set it up right. I’ll check the temps after I play for a bit next time, since I don’t remember off-hand what the GPU settles at. I think Argus can tell me if the GPU is throttling due to thermals? Maybe it was another program, but something can. Its fun but you're looking at like 1200+ CAD to get the whole thing done and a lot of time, not to mention future headaches. I only did it because I got a factory EVGA waterblocked 3090 at MSRP. All these GPUs are automatically overclocking themselves based on thermal state so they're constantly 'throttling', but in both directions. Do you have a thermal probe you can use to monitor your case air temp near the GPU inlet? That would be super useful. I have my case fans (non radiator intake) on a curve based on my case air temp. If you find your case temps are high that might be the solution. What case do you use?

Sorry I'm on my phone but I would try to get the GPU AIO in exhaust config on the top and the cpu AIO to intake config on the front. Use the bottom fans for intake and keep the exhaust fan. Scale the intake fans on the bottom and that rear exhaust fan to a thermal probe for case temp and scale the AIO rad fans to their respective coolant temps if you have that information accessible. Leave the pump speeds on the aios around 50% imo if you don't feel like playing with that. I suggest finding the audible floor of your fans and setting all of them to just below that level at baseline. My reasoning for the positioning is the tdp of the GPU and therefore the energy it is turning into heat is better dispersed directly out of the case than the cpu heat load, which is less.

PoizenJam posted:I agree with parts of this in principle, but placing the GPU at the top of the case is not (physically) possible with my current setup, and would also place the pump at the extreme top of the GPU AIO loop (i.e. the pump is in the RAD, not the water block). But also, isn't dumping the warmed air from the CPU RAD into the way-warmer GPU RAD going to just decrease the effectiveness of that GPU AIO? Ah sorry I missed the part about the pump being on the rad. And yeah it's not ideal but with two radiators and that configuration you can't do all of them as exhausts. I tried! See my posts earlier in the thread. I'm not convinced that pump speed helps cooling and I believe there is actually a performance falloff at both ends - too slow and too fast. You might want to try not scaling your pump speed and see if you get better results. I'm nearly certain that 100% pump speeds are worse than 80% for example and that somewhere is a sweet spot from 50-80%.

Indiana_Krom posted:IMO if you have two radiators they should either both be on intake or both be on exhaust, I experimented with my own two radiators and both on intake kept my coolant about 1-2C lower at load compared to various intake/exhaust/mixed configurations. I settled on both as intake because my case has filters for the locations where I have my radiators mounted so I could minimize dust intake by making my case positive pressure and drawing in all the air passing over my radiators from outside. As a result my case has 5 fans on intake (280MM + 420MM radiators) with only a single fan in the back on exhaust that barely needs to exist at all because the positive pressure is so high. But it works and quite well at that, when my system is at load you can easily feel the heat blowing out the single exhaust fan in the back. Have you looked at your temps for other components in the PC? When I had both radiators drawing air in my HDDs were getting into the 50C+ area. Yes I have a few local HDDs in addition to a variety of other storage.

Nolgthorn posted:Akasa SOHO AR AK-FN108-KT03 120mm - x3 I think the best process for fan speed stuff is to set them all flat %s, start turning it up, and see where it's actually audible to you in a quiet room. Make a note of that % and then keep going up, make another note of the % at which you consider it louder than you would tolerate while gaming or rendering or whatever. Set the floor for the fan speed 5-10% below the audible level, and set the max to just before the point at which you consider it too loud (or have it plateau there). Have the morphology of the fan curve however you like in there, probably an increasing arc like y=x^2 kinda thing because you do want to let the coolant heat up to a point - it makes the transfer of heat to the air more efficient (requires less fan speed/noise). Looking at your fan curve, I would experiment with making it a little more of an aggressive ramp up but it's really not that big of a deal - figuring out the acoustic preferences like I mentioned I think is more important. Myself and the buddies I know who run custom loops target around 40C for the coolant temp, allowing it to go higher in synthetic tests, usually not really much higher than that 44C you mentioned. The threadripper does change this of course, I don't know the TDP or the max recommended temp but for sure with that single radiator and that CPU you'd expect to have the temp exceed 40C under extended time at full load. I would guess that the temps you described in your earlier post (80s and dipping into the 90s) are perfectly safe. The fans blowing air in 'weird directions' in the case shouldn't matter too much so long as your net intake is sufficient and your GPU isn't exhausting somehow right into the CPU radiator (it isn't). e: Looked at your photos again - I have a fractal case also and my front fans are moveable up and down, like where you screw them in is actually a vertical channel on each side; if you can I would drop the fans so that the top fan (of the two front fans) isn't blowing as much into the side of the top radiator and rather is able to push cool air across the surface of those radiator fans.
