if the cpu is indeed overheating should i be able to feel some sort of heat radiating from it? i cant...
One...keep your hand out of a running machine. Two...no you cant feel heat radiating from it, thats what the heatsink is there for to catch that heat, but beyond that, it's overheatin in 3 seconds and shutting down, thats the internal temperature of the chip and the core, that's a tiny area allbeit hot, so theres no way you'd be able to feel it. Also 'feeling the air' inside of a case is in no way any shape or form an appropriate way to check if something is hot so I really wouldn't bother trying to 'hand read it'
When I first seated the heatsink on the 64 machine I built it hit up at 70C on full load so I resat the heatsink and temps went down, so I suggest you do the same thing.
You put a dot in the middle of the heatspreader on the CPU and then put on the heatsink right? As that's the best way to do it. A BB sized dot of compound in the middle, put on the heatsink and twist it each way 1 degree...mind you 1 degree is about a hairs width so I'm talking BARELY twist it, it's supposed to get out all gaps and bubbles to make perfect contact. Personally I think those heatspreaders seem to be causing more troubles than they do at solving heating issues as it seems it'd be better for the heatsink to simply make contact with the actual core and not have to go through a heatspreader, compound, THEN the heatsink, but eh what do I know, I'm not AMD Scientist
