I have recently updated my build by gutting a 1 year old Alienware x51 with i7 2600 onto a new MSI Z77A-G43 mother board. Boot up is fine but the upon BIOS launch the CPU fan kicks into overdrive and stays that way. Even running idle the fan is comparable to jet turbine and running speed fan states the CPU temp at 49C-50C which is a lot higher than I was expecting. I have not even tried to run anything more demanding than google chrome but the diagnostics report the CPU is fine and not in danger. I would like very much to not buy a new CPU but I fear that something is wrong internally that I am not able to diagnose. Any suggestions?
