So I just built myself a new computer (the first time building it myself) and I'm having a few issues with CPU temperatures. I'm using one of the 2nd gen Core i5s (2500k) with the stock intel cooler. I'm fairly sure I fucked it up a little when I was installing it the first time (I accidentally lifted the heatsink after pressing it on the first time), it was working however. At this point it was usually idling at about 37 degrees in Coretemp.
I figured I really should re-do it as the fact that I messed it up initially was always in the back of my mind, so I bought some thermal paste (the cooler comes preapplied). Before I did it I ran some tests to see what kind of max temps I would get before and after (prime 95) and I was getting 71 degrees at 100% load. So I've reapplied it now, and I'm getting temps pushing 80 degrees at 100% load. I read a lot about proper application/cleaning and I'm confident I did it right, so I don't know how to explain it.
Now I've read that thermal paste can have a burn in period, but it can't make that much of a difference surely? I've been running stress tests on and off for the past little while and have seen a slight reduction in the max temperatures, but does the extra increase suggest I have screwed something up putting it back in the second time?
Help out a computer building newb?
Did you apply more more thermal paste in addition to the layer of paste that comes pre-applied with the cooler? Too much thermal paste can't be good for the heat transfer.
The last time I checked, my CPU temperature came close to the 60 degree C zone in the BIOS/EFI settings, which makes sense as I have a small case where the heatsink area is known to get hot. It's been running completely stable for over a month, though.
