Not the only one with that problem:
I also have a soyo P4VTP board, P4 Northwood 3.0ghz, 512m pc3200 ddr ram, with the whole thing running at 800mhz FSB and I was getting the exact same temperature readings as the original poster. 44C on the motherboard when booting (in the bios temperature reading), and sandra reports 75C on processor 1, and 22C on processor 2. Of course there aren't actually 2 processors -- it's hyperthreaded. I have occasional instability, which makes me believe that the heat is getting to my machine. But only occasionally, and only when reeally pushing hte machine in 3d games. Windows itself runs fine.
I wonder if perhaps the hyperthreading is the cause of the heat? I migrated my disks from my old machine, running XP pro. My understanding (now, and I'd love to be corrected) is that you should install XP again if you have a multiple processor (or hyperthreaded) machine, because XP can install a multiple processor support. Otherwise you're spinning cycles for nothing. Anyone know anything about this?
I am dubious about the 75C reading from the mobo sensor too, because the heat sink is cool to the touch. Sandra also warns that the cooling system thermal resistance is 0.64C/W, which is too high. I removed the wax that came with the boxed processor on the heatsink, and put in some arctic silver on the CPU, as per the instructions on the artic silver site. I lost 1 degree for all that, bios now idles at 43C. I do however notice that the chipset heatsink is VERY hot. So perhaps thats the sensor that is giving me these crazy numbers? You'd think though that the bios that came with the MOBO would have the right sensor for the temperature. Is there an easy way to externally check the temperature a processor is running at?
Soyo apparently does not allow hyperthreading to be disabled in the most recent version of the bios, I've got an email into their tech support. I'll report back what I hear from them.
Thanks all,
Dan
