5820k running hotter than expected - Page 3

post #21 of 32

1.35v on my 3570k had my temps in the 70s easily. The solder on this chip brings that down so I'm liking this chip. Glad I didn't go Skylake.

I'm at 1.38v with HT enabled on air.. I'm maxing 64-67c after extended 100% load encoding, never seen over 45c in a game. I'm not delidded.

There are a lot of people saying this and bad things about Skylake TIM, you have to realize it's about 20-25c cooler than Haswell even with bad TIM.

Anyways im pulling my hair out with this 5820k. It seems to prefer lower input voltage especially when its hot.

Your Sig shows you have an I5 3570k, and yes you are correct the 5820k does have solder between the IHS and the die.

So, last night I ran a quick benchmark on AIDA that tests the GPU and CPU and on the last test the temps shot up from 78c to 95c almost instantly then dropped back down to 80c after a second or two before I could stop the test. bigeyedsmiley.png

I think I'm done fiddling until get that cooler off. The pucker factor is just too high. Hopefully I didn't do any irreparable damage to my CPU.

I doubt you did any damage, the CPU will throttle, and if it has to, shut down the computer before you do any heat damage to the CPU. I'm wondering if you have some air pockets between your cooler and IHS, that could cause the spike and drop you saw.

The CPU will throttle at TJmax (PROCHOT) and shut off about 20C above TJmax (THERMTRIP). The PROHOT throttling can often be disabled, but a shutdown at THERMTRIP cannot be bypassed.

It's certainly possible for heat to accelerate damage/degradation over protracted use, but a few seconds with a mild current load that only reaches several C below TJmax is not going to harm anything.

The temp spike was likely just an unusually demanding portion of the test. Most of AIDA64's stress test are very light weight, but a couple of the FPU tests are more demanding. The GPGPU FPU tests qualify; double precision Mandel is much more strenuous than any of the other tests in that benchmark.

That happens with changes in load on the CPU. Haswell and Skylake are extremely vulnerable to that with certain specific loads since their power usage (heat output) rockets up when high performance avx2/fma3 code is ran for any sustained amount of time.

Aida has several tests in their stability test thing alone, one of them is an FPU stress test that abuses those instructions. If it's enabled alone, temps go way up

ASUS "changed" what they monitor good few years ago which caused this, can't remember if it happened with Z68 or Z77 but what they changed is exactly this 10 degree difference. You want to use HWInfo etc which all match vs. ASUS.

Reseat your cpu cooler,and apply TIM a small pea size.but for high TDP proccesor a 240mm AIO would be a better choice

Both HWmonitor & AIDA are reported core temps while AI Suite is reported CPU temp using the motherboard/BIOS sensor. The AI Suite CPU temp should be equal to HWmonior CPU temp (under motherboard >> Temperatures >> CPU). With Intel processors, core temps are the ones you want to monitor.

My favorite is small "X" or "+" in the middle especially CPU with large heatsink like 2011 processors. However, your issue is most likely the heatsink is not seated properly rather than bad TIM job.

Yeah I'm guessing op is doing the FPU test. That test will cause x99 processors to hit 100c even underwater, let alone air.

Try something like occt instead, it uses linpack and doesn't get as hot.
