In a moment of weakness, and mania, I bought a 8086k in the quest for 5ghz stable. My 8700k only did 4.8ghz at reasonable volts with my AIO cooler. That 8700K was delidded, ran at 4.8ghz 1.36v, and maxed in the low 70's C in general. Before delid, it would peak well over 85C and programs would shut down due to temp limit.
The 8086k on the same Artic 240AIO cooler couldn't do 5ghz like so many reviews and reports suggest. Temps would get out of hand above 4.8ghz and 1.25v set in bios. At least this chip would do 4.8ghz at MUCH lower voltage. Attempts at 5ghz needed 1.3v to start stress testing, but temps would immediately spike to 85-90C and programs would shut off due to temp protection.
Over the course of a weeks use, and back at 4.8ghz and 1.25v just to keep temps more normal, I started to notice my temps going much higher. At 4.8ghz just loading 3d Mark would spike 2-3 cores over 85C for a split second and at the end of the run, all cores had seen 80C+. I rechecked/applied TIM to the cpu/AIO block a couple of times w/out help.
I got around to delidding the 8086k last night. Popped it in tonight, same AIO cooler, and at 5ghz I'm maxing in the mid/high 60's right now. My rad hasn't totally heatsoaked yet, so I'm sure this will go up over time. But I'm 10 mins in and with the stock Intel paste/TIM it would immediately spike to >85C and shut down OCCT before I pulled it for delid.
Inspecting the TIM interface during the procedure, I could tell about 2/3 of the cpu had a very THICK application of the paste which I assume was causing the high temps and as temps seemed to be getting worse over the past week, I'm assuming the TIM was cooking and not as effective. Intel should really be ashamed to have pushed this cpu as some special edition. I know I'm a tool for spending so much, but what can I say. I wanted 5ghz, and thought it was my best chance when buying a wild cpu.
