I'm looking for some input from owners of the MSI 645 Ultra motherboard and
P4 Northwood CPU.
I am running the 645 Ultra with the latest BIOS 1.5, and I feel that my
Northwood CPU (1.60a) is running abnormally hot. In Windows I am seeing idle
temps of about 42-44 degrees C. Under full load I am seeing temps as high as
55-57 degrees C. From what I have read from other Northwood users, this
seems a bit hot for this CPU and it's clearly a lot hotter than my old
Athlon XP1600. I was overclocking the CPU to 2128 MHz (133x16) and thought
at first that this may be the cause of the thermal issue, but it runs at
almost the exact same temps at 1600 MHz (100x16) than it does at 2128 MHz. I
read something a few weeks ago about the MSI BIOS for the 845 misreporting
the CPU temps. I am wondering if there may be a similar issue with the 645.
My case is a mid tower and relatively organized, all the cables are tied
back and I've tried to maximize airflow as much as possible. I am running 2
HDs and 2 CD ROMs but this seems to be fairly normal for PCs these days so I
don't think that is a major contributing factor. I am using the retail intel
heatsink and fan, an replaced the thermal pad with Arctic Silver thermal
grease. I've made sure the heatsink and fan are securely fastened.
Interetingly enough, the heatsink is not very hot the touch.
I'm wondering what kind of temps other 645 users are seeing, and
specifically which BIOS they are using.
Thanks for your input.
