Overheating CPU

[WolfRamAlpha12]

Hey all,

I recently had my 8700k delidded by silicon lottery. Once I did end up putting it in my system, couldn't clock it over 4.4GHz without throttling in Aida64. I figured it might be a bad delid, I sent it back to them for testing and binning. They just got back to me with sub 70 C temps while clocked at 4.9GHz in P95.

 

Their setup was (@1.36V) Maximus X Hero, Corsair H105 AIO, while I used a (@1.32V) Gigabyte HD3P rev1.0 and a Corsair H100i v2. 

 

I'm guessing there's something wrong with my cooler, right? Is there anything short of testing on a different cpu I can do to confirm this? And is there anything I should know before I RMA it?

 

Thanks!

Voltage?

so what is your setup? how hot does it get to throttle?

the respective ones are in parenthesis next to the setups (1.36 for them 1.32 for me), sorry if that wasn't clear.

I see. Does HWMonitor or something report accurate voltages while in your OS?

(@1.32V) Gigabyte HD3P rev1.0 and a Corsair H100i v2. The CPU went over 100C in about 15 seconds.

Have you removed the cooler, cleaned, repasted and remounted? This kind of sounds like an issue with your pump.

Yeah, it varied b/w 1.31-1.33v depending on the load

I did that about 4 times(pea size, line, spread with a spudger). I even got a IC graphite thermal pad to remove any chance of a poor application. Those only increase temps by 2-3C, not enough to explain the delta b/w my temps and their temps

this is the problem!! as if no cooler installed

reseat it or may be faulty pump

Are the cooler's fans connected? Sorry, I know it's a dumb question, but worth asking before you RMA something. Do you have a different cooler you can try?

Yeah, I did replace the stock fans with Noctuas, but they show up in the Corsair software with RPMs reporting just fine. I did feel the mounting surface of the cooler, and it felt uneven with several grooves along one direction. It was nothing crazy, wasn't even visible. Is that something of concern?

The corsair software shows the pump running at standard speeds, and I can game and use my PC just fine, its just that the temps reach 70C in most tasks.

kinda sounds like a bad cpu to me. I don't have mine delidded and can reach 5.1ghz hitting in the 80c but I am also water cooled.
