Hello, I'm wondering why my boot temp on my cpu is so high. I have an xp 2000 slightly o/ced to 1750 MHz. When I boot up, my "cpu temp on die" is at 52 C. Is that normal? My "external cpu temp" is only 36 C on boot up. I've tried upgrading my stock hsf to a volcano 9 and still the same problem. I'm thinking of getting another hsf, but is the hsf really the problem with a high boot up temp? Does a good hsf combo with AS3 boot with a high temp and then the temp gets lower? Or is it supposed to boot up at a low temp and stay pretty low? I've got a soyo kt400 dragon ultra platinum. Thanks

the volcano 9 is almost overkill. use your BIOS to check CPU temp after it's running for about 5 min. it should be around 40C and under load when you check it in windows it should be about 50C any higher than that and you have cooling problems somewhere 1> case ventilation 2> improper thermal grease application 3> ur cpu fan speed is set low-depending on what method u control it by.

Thanks for the reply. I do use my BIOS to check my cpu temps. At boot up, the cpu temp on die readings is at 52 C, but the cpu external temp is only around 34. I don't think it's a ventilation problem cuz I've got 4 case fans right now and my mainboard and other temps are all very low (in the 30's). I've tried re-applying the AS3 3 times now and still the same temperature at boot up. Does anyone know if this is an issue with this mobo and cpu combo? Or maybe even just something with the mobo itself?

1st of all, thermal paste, especially AS3 is highly overrated...don't get me wrong, a thermal transfer material is definitely necessary with modern CPU's, but if you think it's gonna lower your temp by more than a few degrees C, you're wrong. If you check the Arctic Silver website, they claim 2-5 degrees C...& it may take several days before you see that temp drop because it takes a while for the paste to settle in. Here's a clip from their website: "Due to the unique shape and sizes of the silver particles in Arctic Silver 3, it will take a minimum of 72 hours, and as many as 200 hours to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink.) The CPU's temperature will drop as much as 2C to 5C over this "break-in" period." I would suspect case cooling to be your problem. Even though you have 4 fans, they have to be working together, not fighting each other. Your internal case temp should be as close to room temp as possible. Average room temp is about 20C (68F)...IMO, your case temps should be in the mid 20s. If you can accomplish that, the CPU temp will take care of itself.

Hey Jam, so ur telling me that case cooling actually does effect the temperature at boot up??? R u sure about that? Cuz it doesn't make sense that my case cooling would do anything at boot up. But if ur right, how should i place my fans? Right now, I've got 2 intake fans, 1 in the front and 1 on the side. Then I"ve got 2 exhaust fans, 1 in the back and the other on the top of the case. My most powerful fan is the intake on the side. What's the best way to arrange these fans to increase airflow???

die temp is the REAL cpu temp measured right in the middle of the core itself. the external temp is measured under the cpu and almost ALL socket A mobos have the that kind of meausrement(which is terrible inaccurate). Your ondie temp isn't bad. its by far the only accurate temp measuremtn in the computer.

As 666 said, 52c isn't a bad temp. I guess I'm a little confused by what you mean by boot temp though. Do you mean you're booting a cold system, where all the components are at room temp? Then you boot up & immediately check the CPU temp & it's at 52C? If so, what is you're normal CPU temp & your fully loaded temp? As long as you're under 60C, you have nothing to worry about. Even though AMD says you're safe up to 90C, the general consensus around here is 60C or less. As for your fan arrangement, they should be in balance...CFMs in should equal CFMs out...or as close as possible. Warm air rises, so exhaust fans should be placed as high in the case as possible, intake fans should be placed down low.
