Liquid Cooled PC: Weird CPU temps

piccoevo · Dec 9, 2013

Hello,

So today, I installed a waterblock for my CPU and GPU.

i7 3770K - XSPC Raystorm CPU block
EVGA GTX 780 Superclocked - EK SC Titan Waterblock.
1x240mm Rad
1x120mm Rad

GPU - 22C min - 37C (gaming max) @ stock speed
CPU - 35C min - 60C (gaming max) @ 4.5GHz O.C.

Am I wrong in thinking these temps are weird? (CPU only). The GPU runs so much better than I expected, but do the CPU temps seem off? I was running a corsair H50 liquid cooler before and the temps seemed better. I also remounted CPU block several times and tried different thermal paste application methods with no success. Please give me your advice. Thank you.

Well, where are the radiators at in the flow for the water? I mean, does the water go from Cpu to 120 rad., to video card, to 240 rad?

Depending on voltage and which rad you are using, no. Seems average.

My setup goes:
[pump/res] -> [240mm rad] -> [CPU] -> [120mm rad] -> GPU -> [pump/res]

60C is normal i think its very good at O.C because my friend have this processor and they hits 80c but 60 is normal.

Check out this link http://ark.intel.com/products/65523
In Package Specifications section you will see 67.4C is normal

I would easily expect that at 1.2 or 1.3vcore. I'm not a water guy but a friend of mine has a 4x 140mm rad and his i7 4930k @1.35vcore@4.8Ghz hits 55c on average gaming.

True, so I guess it isn't much of a problem. Im just curious, why does my GPU run so cold? When I would game, it would go to high 60s low 70s. Now with an EK block i get 37 - 39 max? Shouldn't your GPU run hotter than your CPU when you game?

I do not know why, but GPUs get massively better temps under water, as you've seen. Try for a bigger overclock!

Yes, I agree. I will probably O.C. it till it gets to 60. Based on temps, that will take a huge O.C. to get to 70 or 80. Does voltage shorten the life of a GPU, or is it mostly temps? Because if I have a huge O.C. with good temps would the voltage not be an issue?

You are adding a lot more heat to the system from your Gpu, so your Cpu will run hotter than when you just had the h50 by itself. Because the water setup is more efficient than just the stock cooling for your Gpu, you'll get much better temps for that part though.
