I have just installed an Athlon XP 2500+, and upgraded the BIOS, from ver. F2 to F7. The mb is a Gigabyte GA7N 400L1, with nForce2 chipset.
I have a copper heatsink with a fan, all the thermal grease, and 2 80mm fans--one pumping out the top back of the case, the other sucking in from the bottom front of the case. And of course the power supply, which pulls from the back, not the bottom; bottom being better as I've read, so I have a small issue there.
Anyway, prior to upgrading the bios, I had a cpu temp of 48 C under heavy load. After upgrading the bios, it's now 75 C. This concerns me, but I've got to think it's a mis-reporting by the new bios, since after the upgrade, I made sure to go back and double-check the bus speeds, voltages, etc, and they haven't changed, all fans are still running, and nothing else other than the bios was changed.
Is anyone aware of this particular Gigabyte bios having such an issue? Also, in EasyTune, prior to the upgrade there were 2 cpu temps listed--CPU A and CPU B (this is a single processor board)--and now it's jsut one. So I'm wondering if in the older version one was core temp and the other might be the temp ambient to the cpu? The previous temps for A and B were roughly 48 and 30 C, respectively, and I'm wondering if these are added together for the new bios?
Thanks for any insight,
