Intel i7-3930 running at 75 degrees on idle

Hi

My CPU (see subject line) has started idling at really high temps and running a game etc causes instability, freeze up and reboots

The CPU is watercooled

Any ideas why this would start happening and what can I do?

Thanks

Not sure what type it is as unfortunately it came with the system. However, I have checked SpeedFans readings with Speccy and Asus AI Suite and Speedfan was showing 75+ degrees whilst the other 2 are showing 29 degrees so Speedfan appears to be the anomaly.

Whilst I am happy that the temp is actually normal, I am now concerned over what is causing the freezes/lock ups and reboots

I have just uninstalled and reinstalled the Graphics driver but am stumped for what else to look for?
