5.0GHz on the 9700K
AVX offset 3 @ 1.150 VCore - 3833
AVX offset 2 @ 1.175 VCore - 3924
AVX offset 0 @ 1.195 VCore - 4096
Why don't you try out Prime95 and see if you're still stable at those overclocks? Small FFT's would be a real test, but the large FFT's with AVX/AVX2 would probably give it a good workout.

I also got a corsair ax1200i but that one dips a bit on the 5V rail and 3V rail. not as good in my opinion.
SanAce makes much more powerful 140x38mm fans than anything Noctua sells (in both CFM and static pressure). They even have 140x38mm fans that have Al frames. The ones I've read about have PWM control too, but they're all too expensive for me.

SanAce even has a 140x51mm, 610g, monster fan that has enough static pressure and CFM it could probably stop a Noctua 140mm fan if the outputs were hooked up.

Already have one (1600 T2) and it is a very good PSU, rock solid voltages. My EVGA 1300 G2 had good voltages too until it EXPLODED. Now I am on my 11 year old silverstone that was previously in the "donate to charity" bin

I can run my chip at 5.4 daily but i'm really hesitant because temps will sometimes goto 85c during gaming. it's usually around 1.45v-1.47v load voltage for 5.4 ht off. Should I not run 5.4 because of the temps?
As far as voltage degradation, I'm not worried about it, if it happens, it happens lol. Condensation, leaks, etc. are much more of a worry. Plus my old psu literally exploded, so this whole rig is running on borrowed time It is not my primary rig and I can stomach a part loss if it were to happen. Though, I have had good luck so far. My opinion, if you can keep it below 90c max running the stress test of your choice, you are good

I have HT off as 8 cores/threads is optimal for the games I play. Right now my ram is b-die Trident Z 3200c14 1.35v set at 4600 20-20-20-40 1.5v. I left the sa and io voltages on auto, would have to check what the board gives me. CPU cooling is a very custom water loop, single HWLabs GTX 360 radiator with 3x2200rpm ek varder fans that I run at full speed, EK nickel water block, not delidded, using the crappy thermal paste that came with the waterblock (basically one step above toothpaste, lol). The water stays around 23c in the loop, cooler than it would in a case where heat builds up, so that gives me a slight advantage. I have 90% water, 10% isopropyl alcohol in the loop as a biocide. It is 24/7 stable with temps comfortably and consistently in the 80c range running prime95 smallFFT noAVX. The chip consumes around 230w.

I used to run it on a custom chiller, but took it out of service due to a mold issue. There I ran it at 5.6 GHz, 1.65V with the water at 4c. 24/7 stable as well, with the same testing as above. I could boot into Windows at 5.7 around 1.7v, but could not get anything at 5.8.

These chips can run as high as the cooling solutions allows. This chip runs ice cold compared to my 7980XE (95c at 4.3 )
