Quite a high power system for a home server. Couldn't you have used a lower power, more effecient CPU?
This system was originally planned as an app server for work, where it would be shared by multiple developers. The company decided to go with an IBM server instead, and let me use the CPU, motherboard, case and RAM for building a server for myself
badge, thanks for the advice. The cooler is properly mounted, so I guess I will check the CPU on another motherboard and see what happens.
