CPU Temp too high!

[JEDORI]

I have a Mach Speed X-Caliber VIA Socket 478 ATX MB and a P4 2.8 GHz CPU w/heat sink and fan mounted. PC freezes during OR ofter POST, definitely heat related. Changed out the PSU and RAM a few times. CPU starts @ about 70C and goes up rapidly. Any help? Need a better HS?


Thanks!

Sounds like either the heatsink is not seated fully on top of the cpu, or there is no transfer compound between the cpu & the heatsink.

Heat Sink had a yellow transfer sheet on it but I put some transfer compound on it. I have tried setting the HS both ways on it.

Remove all paste/tape and reapply a small amount to the top of the die. The heatsink only goes on one way if you can't tell which way is correct get someone that can. DO NOT run it the wrong way, it only takes seconds to destroy a CPU.

Hola,

do what was suggested by Franklin (as the TAPE you mentioned is mostlikely the shipping cover of the heatpad and by no way should be left on the HeatSink)... btw, on a Socket478 the HS-Fan fits either way (if it's one from Intel itself)... if this then alleviates the problem, then it's good...

if it doesn't, then take a look at your RAM module(s) if they are OEM's replace them with known good one (like from Infineon or Samsung, etc.)... as I've come across a few OEM's that seemed to be ok (ran three diff RAM testing Progies on them - all said RAM is OK), but after a few minutes would lock up the PC...

If it works don't fix it! If it doesn't use a sledgehammer...
