Hi, my main dev rig has started to misbehave. Nothing has changed on the machine but a few days back it popped up an alert from the Asus monitoring software "warning CPU temp 86 degrees" which I ignored as assumed the software was reporting incorrectly. Few minutes later the PC locked up and hung - which it never does.
Restarted and all was good until I started an encode in Handbrake - same again. Can replicate this each time something intensive like video work is run.
I can only think of:
A) Asus software reporting wrong temp, this was disproved by the way the machine actually crashes after a few mins of intensive work.
B) Cooler fan packed up - visually checked this and fan is running fine. Checked reported speeds and again fine. Set fan to more aggressive profile in BIOS and speed increased but temp issue persisted.
C) Cooler unseated somehow - checked and appears seated fine, is solid and no changes had been made inside the machine prior to this.
Chip is 2600K with a very mild overclock on Asus Z68 board and cooler is a decent-ish Freezer Pro one, not a stock cooler.
Any ideas where to look next, beyond replacing the cooler? Gaming works fine and it'll happily run games all day but I guess that's not really pegging the CPU?
