Hey guys, I'm having this weird problem after i applied my thermal paste and everything is okay i started the PC and the CPU temp was perfect, after i shut it down and try to turn it on again the CPU goes to a crazy level that i have to remove the cooling unit , re apply the thermal paste and start it again.

the problems keeps repeating 

any solution ?

 

My PC specs are :

CPU :Intel I7 5960X (i didnt overclock it yet)

RAM :64GB Corsair Vengence 2400mhz

Graphic Card: Nvidia TitanX

I suspect you are not getting proper seating of the CPU heatsink and it is "cooking off".  There should be very little clearance on top of the CPU and the heatsink, only a small teardrop sized dab is needed and spread very thin.

Perhaps too much thermal paste?  Just a wild guess...too much is akin to too little when it comes to system cooling, IMO.

The only way I see this happening as described would be that the heat sink and CPU surfaces are not flat or there is a gap between.  This would allow the paste to heat beyond its ability to remain stable and it cooks off.  The thing is, while running, the fans keep it cool enough but when shut down, the residual heat is cooking the paste.
