try to check the thermal paste if applied well or the heatsink properly installed
The stock heatsink comes with thermal paste pre-applied so that wouldn't be the problem unless he kept taking the heatsink off and on. He probably didn't seat the heatsink right. Make sure the black male pins are all the way through the clear plastic female adapters.
Wow.. I have seen a LOT of silly things customers do in my shops but never that.....yet..lol
All the best Brett
I had a guy that soldered 3 hdd's together. He said they were easier to cool together than separate. Hope he doesn't need warranty, one of the drives was bad and he wanted all 3 sent back for replacement. lol
Also had a machine the whole inside was a bull ant nest, full of wood and straw and mud nest and when we opened it the entire tech room was under siege from about 500 bull ant's scattering everywhere, what a mess that was.
