High temps?

post #1 of 10
Thread Starter 
First things first, my specs:
-i7 6700k
-2x 980s overclocked
-Asus Maximus Formula VII
-SMA8
-EK Supremacy MX
-Corsair SP120 intake to the left of the motherboard
-XSPC AX360 with 3 Corsair SP120 silent fans
-Hardware Labs Black Ice SR2 560 with 4 Corsair SP140's
-Each loop has its own XSPC Photon 170 with D5 Vario set on slightly above the slowest speed

Temp info:
-Ambient is about 71F
-CPU idle is 31c
-CPU max after an hour of Overwatch is 56c on stock clocks
-GPU idle is about 29c
-GPU max after an hour of Overwatch is 53c
I feel the GPU loop is fine

The issue?: The CPU loop contains a Photon 170, 6700k, the EK block on the motherboard, and the AX360. I feel that the CPU is running too hot. I went to overclock it a few days ago to 4.6 at 1.35v and it maxed in Realbench at 81c.

-Could the CPU radiator be getting heatsoaked? Since it exhaust out of the top of the case with about 2 inches of clearence from the bottom of my desk, could it affect it this much?
-Another thing is if I speed the pump up, I'll get bubbles. Normally this means it isn't bled right, but I've sped it up everyday for the past couple weeks with the same amount of bubbles. There are no leaks but I have no idea how air could be getting into the loop. Should I replace the pump?

If anymore info is needed, I'll be glad to supply it.

are you using the gpu rad to intake?
if you see bubbles, they need to come out. tilt n rock your case while the pump runs. it should dislodge them.

The GPU rad is in the bottom basement of the case, completely separated from the rest of the PC.

For the bubbles, I've done that repeatedly over the past weeks and nothing has changed. That's why I'm thinking the pump might not have a perfect seal (attached to the res) and could be sucking in extremely small amounts of air without allowing water to leak out.

Turn the pump speed up, I had to set mine up to around 4 to get it to move water at a decent enough rate. at 1-2 the water was barely moving at all.
This was with a single rad, res, and cpu block.

This sounds like solid advice. Just a tick above slowest speed is probably not getting enough flow through the loops. Try bringing them up to 3-4 and see if there is a change in temps.

What speed are you running the cpu rad fans? Do you have an exhaust fan at all?

Most folks set that pump to 4 and forget it. Seems to be the sweet spot for perforomance vs. noise. Just let it run and the bubbles should eventually work themselves out.

Are your gpu blocks full cover or are the VRM's still being air cooled?

Try turning the top rad fans to intake and redo the TIM.

I quess part of the problem is the tim under the ihs of your 6700K, I have the same problem, some liquid metal and delidding should improve things aswell, I`ll do mine tomorrow and let you know how much it helped thumb.gif

-The CPU and GPU rad fans are all running at near idle. If I increase the speed of the CPU loop fans (Corsair SP120 silents), they'll make a very annoying clicking noise like the bearings are shot already. GPU fans are fine to ramp up if I need them though, no clicking at all. I don't have any complaints about the GPU loop since it's doing pretty good (I feel) while being overclocked.

-I'll increase the pump speed but I want to get some sound dampening foam for this case since I'll get some (mad) vibrations (yo) and noise. I love SMA8, but it really is a giant empty metal box that amplifies sound. Any suggestions?

-They're these blocks: https://www.ekwb.com/configurator/upload/pictures/EK-FC980-GTX_NP_front1_1200.jpg , so yes they are watercooled.

-I was considering that actually since I have a exhaust fans at the back of the case.

I'm still seriously considering that but I don't trust myself. I did see a video where some (German?) guy had a metal bracket that he dropped the CPU in after taking a razor to the edges. He closed it up, turned a lever on the outside, and popped the IHS off.

Saying the fans run at idle doesn't tell us what speed they are running. What is they're RPM when the CPU is at full load getting high temps? (The fan noise isn't a concern at this point because you just need to find out why there is high CPU temp, and fans can be replaced if that's the problem).

Can't help you with the CL noise because I don't own one, but everyone says they're the be all end all and spending an entire paycheck on them you will never buy another case again and I can't imagine they have any faults, so... /sarcoff

Since they are full cover blocks then you can rule out the VRM's causing unnecessary heat i think.

Again, I would put top rad as intake and redo TIM to see if that makes a diff. I know delidding helps, but I don't think that's really your problem here, there are plenty of folks running that CPU on water with no problems.
