68c Maximum Reported Core Temperatures in Time Spy?

[Sturmgewehr_44]

Is this normal? I am running a stock 8700k and H100i GTX V2. This obviously refers to the CPU test.

Firestrike yields significantly lower CPU temps during the physics and combined tests.

Edit: This is likely because the Time Spy CPU test runs AVX2, whereas I assume the Firestrike equivalent does not. However, it is still pretty concerning.

sounds normal. AVX2 is a factor. Time Spy CPU test scaling to more cores is a factor.

Fire Strike CPU test is basically for quad cores. Time Spy scales well to 8 cores and somewhat up to 12-14 cores. Time Spy Extreme has by far the heaviest CPU test and is designed to scale to 64 cores.

Basically to compare CPU performance, you should run the heaviest CPU test you can (which is most likely Time Spy Extreme CPU test if you have Advanced Edition, unless the system is really low end, ie. dual core)

Time Spy Extreme CPU test temperatures yields temperatures up to 73c for me. Is that to be expected?

Since it is the heaviest test, getting ever higher temps than in Time Spy CPU test is to be expected. Sounds normal. All modern CPUs have protection that they throttle before the temperatures get risky and this is still far away from throttling anyway (I think 8700K throttles at around 95C if I recall right)

Could XMP have anything to do with it? Max temperatures around 75c seems far too high even for AVX2. It is a bit unsettling, especially since I am running a 100% stock 8700k and have never attempted to overclock it.

My RAM (16GB DDR4 in dual channel) is rated for 3200MHz so I am running it on XMP at that speed. Could that mess with CPU voltages? I do not have much experience in overclocking so I am not sure in what ways enabling an XMP profile could effect CPU voltages.

It could also be that my AIO is failing (I've had it for three years and it has been replaced since with an updated model). This rise in temperatures appears to have been gradual and I believe started after I upgraded my RAM, CPU, and motherboard in August 2018. My previous 4790k definitely ran cooler, but I think the temperature increase could be because the AIO pump is slowly failing.

I reapplied thermal paste twice yesterday, and nothing improved (I thought that maybe the mounting hardware became loose due to moving), so really I do think the problem could be my H100i GTX.

Your temps look exactly right to me, not at all worrying. I have a similar setup, 8700K with corsair H110 which I've had over 4 years now (although was originally used on an I7 4790K). I got a max temp of 68C during a time spy bench run and I have an extremely large and well ventilated case.
