Thanks man Being able to test stability quicker is pretty valuable, I'll definitely try it out.

Yeah, and considering it was actually running all core 5Ghz I think I'm gonna try and reach 5.2. But this time manually instead of the machine doing it by itself.

Sorry for the slow response, was kinda busy. I did however take a wild gamble after remembering a post I saw a while back mentioning that if unlucky, the block might not be properly flat. So I went and bought a new cpu block and quickly installed it today (the xc7 again of course, need the aesthetic of using the same brand) And now the max temp it reaches is 70-75c when running the torture test in Prime95 (mind you the room temp is around 27c). I do still see a little bit of spiking, but not in the same way. I also checked the bios, and it is running with MCE on. I can also see that the package is reaching a max of 150w in CPUID, which also suggests it has been overclocked. All in all I think it's pretty acceptable. Might try reducing the voltage and see if that will make the temps better whilst still running stable. And thanks a ton for the help guys, I appreciate it.

It's a completely new build And unfortunately I didn't check thermals when I tested the hardware with air coolers prior to installing HydroX.

I use the criss cross method too so that I can be sure that the thermal compound is spread evenly. And when I've removed the block I've checked if it's spread evenly, and it has been every time. It also covered the whole cpu. This is why I have a hard time figuring out what's causing the high temps.

If by vCore you mean the voltage the CPU is running then it's 1.306V currently when looking in HWMonitor.

The asus rog strix z390-e, which is on the compatibily list.

I just recently built a system based around hydro x cooling. Problem is the xc7 has stupid poor cooling performance for me. I use a 9900ks (stock settings so far, cant oc with these temps). The temperatures spike a ton when idling/doing simple tasks. Opening google chrome will make it spike to 60c. And it's much worse when I try to benchmark. Running prime95 I'll be lucky if I stay at 80c, but in most cases I'll reach 100c instantly and the computer then freezes if I dont stop it. I've tried using different thermal compunds: Arctic Silver 5, Thermal Grizzly Cundoctonaut and Artic MX-4. All with the same result. I've also looked at how the Silver 5 and MX-4 spread across the IHS, and it seemed fine and even. I also use the XG7 on a 2080ti, and the temps there are much better, as it stays under 45c when running timespy. After disassembling the cpu part of the loop 5 times I'm not sure what to do. Does anyone else?
