How are these temperatures on a new custom loop?

[eismcsquared]

So I finally decided to venture into custom water cooling. I have the following parts:

• Case: Phanteks Evolv X
• CPU: Ryzen 3700X @ 4.3 GHz 1.35v
• GPU: EVGA RTX 2080 Ti Hydro Copper @ ~2115 MHz core, 8000 MHz memory
• Rads: Corsair XR5 280mm & 420mm
• Fans: 5xEK Vardar Evo 140mm @ 1200m (typically) on radiators, 1xCorsair ML140 Pro at rear of case
• Res/Pump: EK XRES-100 Revo D5 combo (~60% speed)
• Tubing: EK Duraclear 10/13mm
• Fittings: EK-ACF
• Blocks: EK-Velocity RGB, EVGA Hydro Copper block

This is the first time I've set up a custom loop and after spending many hours bleeding and leak testing, the results I get aren't exactly the greatest. My CPU hits around 76 C on a sustained 30+ min Cinebench R20 loop which isn't too bad since I know for this type of CPU a custom loop doesn't make a huge difference vs an AIO. My GPU though hits 53C overclocked and my water temps are 30 C at idle and 41C full load. If I open up my case I get around 38C load on the water temps and my GPU drops down to 50-51C. My ambient temp is ~24-25C (as measured by my thermostat). I'm running the front 420mm rad as intake and the top 280mm rad as exhaust.

 

I've read that for a custom loop like this I should be expecting a <10C delta on the water temps at load but I'm getting closer to 15-16C delta. Also I was hoping for the GPU to stay below 50C. I don't currently have a flow meter connected so I can't check the flow but it seems pretty decent when I was filling the loop. I'm fairly ok with the temps as is since it's the summer time and my ambient temp is higher than typical even with AC but I feel like the water temp/GPU temp could be lower. Are these temps about what I should be expecting or should they be better? Also suggestions as to improve temps/airflow would be appreciated as well.

 

I've attached a picture of my loop as well.

You can't get 10c delta because you only have 2 rads, and these are not XE rads are they?

 

I am running 3 x 480mm thickest rads from EK and my GPU doesn't go past 39C when not overclocked and 42C when overclocked.

Yes, I needed this many rads to get there. I am sticking another XE rad and Revo D5 pump but the rad is only 240mm because that's the only thing that will fit so I can maybe shave off another 3 degrees of my GPU. 

 

Also, where's the 480mm rad? I can only see 1x 240mm and 1x 360mm.

 

I'd summarise that you're getting excellent temperatures considering the loop you have. Lower TDP of the Ryzen contributes to this for sure.

I have a 420mm rad in the front, and the top is a 280mm rad. They are 30mm thick rads (16 FPI according to Corsair). I guess in the future I should go with at least 45mm rads, but I was hoping that since I'm only running a single GPU, I would be ok with 30mm thick rads.

Yea, go with thicker rads.

 

Also, Hybrid GPU would achieve the same temps. My 1080 Ti SC2 hybrid was achieving 50C when overclocked with 120mm AIO attached to it, slightly faster fan speed but it would work and GPU would be cold.

 

Your temps are really good though, and fans are not spinning ultra quickly I am assuming.

 

I'd be happy. Good temps. But to improve, more and thicker rads. My pump runs at 2000 RPM (40% or less?) and I get 39C on my GPU.

 

I haven't tested running it at 100% actually....

I have the fans spinning at 1200rpm usually (around 60%), at full blast (2000 rpm) they are way too loud. Also I thought about getting a hybrid 2080 Ti to go with the H115i Pro I had on my CPU but I've been using dual AIO setups for so long that I didn't want to deal with the noise/cable mess anymore. I guess should probably switch the case in the future as well since I don't think I'll be fitting 45/60mm rads at the front or top very easily inside the Evolv X. The top 30mm rad with a fan in pull is already getting close to the motherboard VRM heatsinks.

 

BTW I have a fill port at the top which I've attached a piece of tubing that then attaches to the top of my rad. Would the fact that I have air inside this tube affect my loop at all? Would I be better off just removing it and closing the top of the res with a plug instead?

I blast my HD120's to 1900 RPM and they're not loud at all weird.

 

I do take care with my 3000 RPM fans though they're loud, but when they are loud temps go down quick...

 

Usually if the speakers overwhelm the PC noise I'm happy (most time that's the case).

 

But yea, more rads = more surface area = longer for liquid to heat up = more fans = more cooling = lower fan speed to keep same temp.

What's your temps after the loops been heatsoked. Load means nothing.  I would let 3d mark loop for about an hour and 1/2 and then check your temps. 

 

 

 

Thicker is not always better. I got some thin xpsc rads that outperform 50mm rads. Thick rads really need a push pull set up. Of you can do that a thinner rad is better most of the time.

Hi @eismcsquared, I can't really contribute to your conversation about how the temperatures are for your loop, but I was planning a build similar to yours (420mm + 280mm rad, in the same case), and I was wondering what vertical GPU mount did you use? Did you buy the phanteks one, and if so where?

Your temps aren't bad, but your DeltaT is pretty high for a custom loop. I Figure it would come down a decent bit though if you turned up the fan speed. My only suggestion would be to play with fan speed to get it to the max speed you can at the volume level you want. Typically I aim for a 5-8c Delta T in my loops, you are sitting at about 16. So assuming you got that down to 8c your CPU and GPU temp would drop as well. That would put your cpu around 68c and your gpu around 45c. Which IS pretty good temp wise.

 

I mean there isn't a problem where you are now. If you are happy with the noise and temps it is perfectly safe, but if you want to increase them just try tweaking your fan speeds. You should have plenty of rad surface area to still get the deltaT under 10c.

I'm using the Phanteks PCI-E Riser card (bought from Amazon) but I'm wasn't actually using the vertical mount bracket (the one that attaches to the PCI-E riser card) at the moment since I didn't have it when I built the loop (misplaced it somewhere but it does come with the Evolv X by default apparently). I have since gotten the mount (apparently Phanteks will sell you one if you e-mail their support). At the time I was just using a piece of foam under the card so that it would be at the proper height of the mounting bracket and it worked just fine.

Yeah I turned up the fans and pump to 100% and also opened up all the panels on my case so it would run just like open-air and I was able to get the temps down by about 6-7 degrees compared to running everything at 60% with the case panels closed. I also hooked up a thermometer to get a better measure of the actual ambient temps in the room where my PC is (instead of what my thermostat shows) and it looks that that works out to be about 7-8 degrees delta between water and room temp. So it looks like the combination of lower fan speeds and the Evolv X not being the greatest case for airflow are contributing to higher temps. Still I'm fairly OK with max GPU temps that generally don't go above 50-51 C during gaming and I'm guessing moving to a better airflow optimized case would be a good idea in general. Still I love the look of my Evolv X and I think the temps are good enough.
