2600k Very high temps @ 4.5 GHz

post #1 of 28
Thread Starter 
I currently have a stable OC @ 4.5 GHz, 1.32 vCore, LLC 1 (Highest LLC on my board), 250 short/long term power duration. Yet my max temps in Prime95 blend are hitting 86-87 after 2 hours of testing.

I reseated my CM Hyper 212+ numerous times, applied arctic silver 5, but still can't get the temps down.

Any help is much appreciated.

CPU Core i7 2600k
Motherboard And BIOS Version ASRock Extreme4 Z77 1.30
Memory G.Skill Ripjaws 8 GB (9 9 9 24 N2)
Power Supply Corsair 650W
Graphics Galaxy GTX 460
Case And Cooling CM Storm Sniper/ Hyper 212+

What are your ambient temps?

What speed is the 212+ fan running at, if stock should be in the 2000 RPM range I believe.

What is your vcore in windows (CPU-Z reading) under load?

Thanks for the response.

Ambient temp is ~ 60 F.

212+ Fan is running @ 1904 RPM.

vCore is pretty much holding steady @ 1.32 volts with a high of 1.34 volts.

Did you apply your TIM like this:

450

and when you took it off was the coverage good?

450

At 60 ambient and the fan at full speed you should have much lower temps at 1.32 volts. I would suspect TIM or mount pressure is the issue. Other possibility is flow through your case, try running with the side door off and see if that helps.

My guesses:
1) Terrible case flow stagnates hot air - open case when it's running to test
2) Find a different program to read temps. Maybe whatever you're using is messing up.
3) Check your cooler for problems.. did they put the fans correctly? When you re-applied TIM, did you scrape off the old stuff with a razor? Is there a bump on Hyper's surface that prevents it from seating correctly? Does it wobble if you try to move it?

It sounds like you know what you're doing, so chances are it's either something very simple that you're overlooking, or you just got a very very bad piece of silicone.

Hmm, I applied the Arctic silver as shown in your pics silvrr. j0zef, there doesn't seem to be anything obstructing the base of the heatsink. I also verified the temps in CPUID Hardware Monitor and they matched Realtemp's.

I ran an hour test at stock clocks and vcore, and the max temps were low 60's.

Can't figure out what might be causing the temps to skyrocket @ 4.5 GHz. Maybe the board came with broken temperature sensors?

EDIT: These high temps only seem to start occuring after the first blend test passes at around the 15 minute mark. I'm also hitting high 80's, even low 90's @ 4.3 GHz and 1.29 vCore.

EDIT2: Running another test now. 4.3 GHz @ 1.25 vCore. Still seeing max temps of 73-82-84-78. frown.gif

@silvrr Did you mean in your picture that I should only apply the TIM to the heatsink and not the processor's IHS? I did both, would that be too much? But even so, I still shouldn't be getting such high temps right? I hit the high 80's on 1.25 vCore @ 4.3 GHz.

I'm starting to think I need to RMA something, but not sure which is the culprit...

On my 212+ I just put a small line like above, nothing on the processor. It will spread out when you mount the cooler. Make sure the cooler is snug on the processor, mine could twist side to side but didn't move easily once fully mounted. You may have to much TIM, it just needs to fill small voids not make a new layer between the IHS and your cooler.

I had a 212 and it really sounds like your heat sink isn't fully mounted. Even at stock you shouldnt be hitting the 60s.

I guess I'll try reseating everything again, although I'm not too optimistic as this will be the 4th time. Is it unlikely that this is just a bad chip?
