Frightening northbridge temperatures.

Hello

I just replaced a pentium D 925 running on my Asrock N7AD-SLi board with a E7400 I got off ebay (Second hand, but with very little use). When I was runing the Pentium D with 800mhz FSb the system was running very well, all temperatures ok.
After putting the new CPU in things have started to go crazy, the higher 1066mhz fsb is frying the northbridge for some reason, temperatures running at 78C at idle(!), this is causing random shutdowns and alot of problems. This has made me think I've got a faulty board, since it should be able to handle the new CPU fine, the board having a 1600mhz fsb rating. I'm going to RMA the board and try again. The only thing I wanted to check was that the crazy increase in NB temps couldn't be due to the new CPU being faulty, since I don't want to try again and have the same result. The CPU seems to be performing fine, good temperatures and fast processing. So it's gotta be a crappy board, right?

Any help appreciated.

Cheers guys.

Nforce chipsets do get hot but not that hot.

Also as your CPU is 45nm you might want to update your BIOS to the latest revision.

Also try to go into the BIOS and do "load bios defaults" as you might have some old settings that are causing it to go hot.

Hi
I flashed the bios with the latest version and reset defaults, no change! :(

Thanks for the suggestions anyway mate. I sent the board back yesterday.
