4770k custom loop temps?

[fezz0]

What kind of temps are acceptable for a watercooled 4770k (no overclock)?

 

My idle CPU temps are around 36-39c.

 

aida64 temps 60-70c

 

Prime 95 for about 10 seconds it shoots right up to 85-90c

 

When running aida or prime, if I check the voltage with cpu-z it says 1.28-1.31v

 

I've tried lowering the voltage to bring the temps down but it bluescreens.

 

I have updated my mobo bios, reseated the cpu block and temps are still really bad.

 

 

My system:

 

4770k stock

2x GTX 760 stock

8GB ram

EK pump/res

1x 240mm rad

2x 120mm rads

 

 

My GPU's never really go above 55c. I always thought GPU's were the warmest componants?

 

Any idea's why this is running so hot?

 

 

 

Forgot to mention, I'm in the UK so it's pretty damn cold here at the minute.

First of all, non-OC'd 4770K doesn't need over 1.15V voltages. Second, don't use Prime95 on Haswell or newer. It will create unrealistic loads and with auto voltage, will also overvolt to danger level. Thirdly, your idles are same as mine with air cooling. Which it shouldn't be. So either you have 10C more room temp than me or bad mount on CPU block. My room temp is 23C.

Thanks for your reply.

 

My room temperature is around 15C at the minute. (maybe less)

 

Please look at this screenshot.

I've now undervolted it to 1.15 instead of having it on auto and here are the results

 

 

60C still seems abit high does it not? considering my room temperature, it's only going to rise when the summer comes.

15 degrees room temp is pretty cold mate.

 

Also, if the room temp is good, then it means you have a problem in the loop.

Pump may be faulty, block might not be seated well, these are the first two things i'd think of.

 

Temps seem pretty high, my 8350(125W TDP) is barely going over 50 degrees(cores) in full render load, and i have 23-25 room temps. Cooler's H80i w/1200RPM fans. 

Your custom loop should be superior to my AIO..so check the loop again.

The pumps definately not faulty, both my gpus idle at around 26-27C and never really go above 50-55C.

 

I have reseated the cpu block and reapplied thermal paste twice but temps aren't any better.

I don't understand how a 84w CPU is getting hotter than 2x 170w GPU's

I've just noticed you say your H80i fans are running at 1200rpm. My Corsair SP120's on all 3 of my radiators are running at 450rpm, is this OK? The front 240 rad is in push pull configuration with 4 fans.

Well...you might have found your problem...450RPM seems a bit too less for optimal cooling. SP120s might be nice looking fans, but the performance is not out of the ordinary. They're not Noctua.

Then again, it also depeds on the loop. The 240 rad is for CPU?

If it's not a problem, some photos would be nice, to see how the airflow is and stuff.

 

ATM, due to other fans in my PC, I can't hear the SPs at 1200RPM, but the PC overall is a bit noisy, It doesn't bother me very much, since I use headphones most of the time.

 

Try to raise the RPM a bit, see if the temps go down.

For 100% load (I assume under stress test) 60C is really good with 4770K. Mine goes near 70C under OCCT stress test.
