Heyya,
So I took the dive and delidded my 8700K (mats: Dr. Delid tool, Thermal Grizzly Conductonaut and Kryonaut, some clear nail "coating"/polish for the 4 small contact points near the die, Victor Reinz's Reinzosil high temp sealant).
I am curious if I did this correctly though, as this is the first time I try it. I mean, the temps look fine, I think, but I'm unsure if more could have been done. Could use somebody with a delidded 8700k willing to either run it at the same voltage, or maybe tell me their voltage and a modest OC (my VRMs are shit, I don't wanna drive more than 150W through them if possible).
My test(s): 5GHz without AVX offset, +0.040V adaptive offset (it puts the CPU at 1.344V in AIDA64 so for static voltage that should do, if you wanna replicate this), CPU/FPU/Cache/memory stresstest for 10mins). Temps peaked at max 73C/core and around 130W were drawn. I'd say that 66-70C temps were the "average".
Another test: prime95, AVX turned off, inplace FFTs 1344K, power draw was higher, around 140W, temps were maybe 5C lower though. I assume AVX from AIDA64 was responsible for the increased temps.
Kinda afraid to use AVX2 or AVX inside p95, would likely require more voltage and also maybe even fry my shitty 4phase VRM. So please not that test, thanks!
Edit: oh yeah, the CPU cooler (D15S from Noctua, 120mm fan in front) didn't really break a sweat, I think the 140m fan topped at around 666RPM and the 120mm fan at around 1K rpm. The max is 1500rpm for the 140mm and 2000rpm for the 120mm. The case fans also ran at kinda 50%. Just putting this here as additional info.
