High temps, not enough rads / wrong case?

[Bacon?]

Hey all

End of last summer I got round to building my first watercooled system with a custom hardline loop. Specs are as follows:

Ryzen 2700X @ 4Ghz 1.45V
Nvidia 980Ti (left at stock)
Fractal Define C (non mesh)
1x 280 & 1x240 radiators

I switched to water because I wanted to dabble in some higher overclocking but predominantly because I wanted to make the system as silent as possible since it sits within 2 feet of where I game / work. For that reason I chose the Define C over a water cooling optimised case.

However even with everything running pretty much at stock I think the temps are pretty high. I should note the 280mm is at the front, and the 240 on the roof both in a push only config and the 240 only has a single 120mm fan as the second one cant fit due to space.

I've uploaded a pic in the spoiler below

The kinda temps I see during regular gaming use are along the lines of water temp mid system @45 degrees, CPU@ 64+ degrees, and GPU maxes out around 50 degrees.

I'm thinking those are some pretty high temps given the lack of a proper overclock in the system. Do you think it's due to not enough radiators and a different case would be better or something else I'm missing.

Cheers guys

I'd say the temps are pretty much as expected, especially with that vcore on the processor (which I wouldn't want to run at long term).

I've had to fiddle with my bios settings cause it would go higher than that, so it's restricted and boosts up that much. It'll boost to about 4.2ghz at 4.4v otherwise it sits at 1.37v at 3.9ghz. I can try and fiddle it again but it's not going to get much lower without dropping the clock speed. Leaving it to full auto settings makes the v-core bump real high at max boost.

I would suggest that's about right. You have one fan removed which will lose most of the benefit of that radiator section, probably 20% of the overall cooling capacity.

I have 360mm+120mm capacity with an i5-4690k and GTX 1070. So with your 980 Ti is probably 100W more heat than my setup. I get GPU temps about 53° at stock clocks and CPU around 60-65 depending on overall load, heat soak etc. To be fair it doesnt stay there long, so water temp is probably around 45-50.

This is a pretty quiet setup though - I can turn the fans up but temperatures only drop a few degrees for considerably more noise.

Water cooling is good but not magic unfortunately, as I learned!

What setup (ie case, rads and overclock) do you run? Cause I figured mine was unusually high and I could get it drop to pretty good with a larger case and more rads. I have the system setup with an Aqaeuro device to shut down if the water temps exceed 50 degrees and at 45 degrees the fans are running at 100%, so its petty loud (though still quieter than the gpu on air)

even throwing a 360 in there your only going to get 5-10 deg lower. the temps are fine for the size of the system .
as has been said the missing fan and the res position will be losing you a bit of cooling .. you could always cut a hole next to the psu and put you pump or res in there

It's a very small case (on purpose I move somewhat frequently and can't always fit a large case in) as you can see in the photos and the setup I have is the maximum size possible.

Dropping 10 degrees at load would be massive cause I could run the fans a lot slower than currently (maxes out ATM at 1400rpm). That's why I'm wondering if I swapped to a case like the 0-11 with triple rads would I see an improvement or are the temps I'm seeing fairly universal anyways.

Unfortunately that's not possible, that photo is the best one I had to hand but the final setup is a bit different cause I had the input and output the wrong ways round on the pump and I have other bits taking up space below the graphics card. I'm just wondering if it's worth switching case for more rads that'd lead to a temp / noise reduction

Don't remember off the top of my head but I think the 2x 140s are noctuas

I'll have a fiddle with the bios tonight, see if I can fiddle with the voltage some more as I didn't think that 1.4v was that high to be honest. And I have a fan curve set with my Aqauero device based on inline water temperature

Fiddled with the BIOS again, looks like the settings got reset actually as the clock speed and voltage was set to auto with pbo enabled.

Dropped the voltage down to 1.35v and all core speed to 4.3, will have a further fiddle later to see if I can get it to single core boost higher but the temperature now has dropped from around 68 degrees to 52 during gaming so that's a nice drop.
