Measuring temps

[w2nut]

Got an Asus P3B-F w/a 450 P3 in it.

When I first booted up the CPU, it told me the durn thing was at 98 (!) C. Ugh. The board was using the sensor mounted on the CPU, not an external one.

Shut it down immediately. Checked the HS, found that it had a pad. Removed, put on the RS HS compound, reassembled and restarted, now it is at 48C!

Still not too good, and it has a massive HS on it. When running single on a dual board, and using an external sensor, the thing never ran above 39C. Same case, too.

Am I missing something here? Are the on-chip temp gauges reliable, or do I need to adjust somehow?

Using MBM 4.17.

Thanks,

I will try the reversal

Sorry for the stupid question but what is HS and what is RS?

HeatSink & Radio Shack (I assume)

w2nut, if the system hasn't been turned on in hours then you boot up and you're getting a high reading (98c or 49c) then it would seem logical to say the sensor is malfunctioning. If you can jump right into the bios and see the temperature (after only a few seconds) then it must be wrong. It's just not physically possible for it to build up so much heat so quickly, even if it had no HS.

What kind of heatsink do you have? Does it have a fan?
I transfered my P3 500 from a Dell and it had only a heatsink. So I bought a Golden Orb heatsink/fan from http://www.plycon.com
I used RS HS compund ($1.99) and it runs about 11-12 degrees C above room temp at 535mhz.
I am happy now. http://sysopt.earthweb.com/forum/smile.gif
A good heatsink/fan is a must.

I have the same mobo and same chip as you, but I have a nice nice heatsink on it with dual fans (cant remember the name right now) and depending on the room temperature, it goes, at highest, 44c/111F . Even when I overclock it up to 558 it doesnt stray much higher than that amount. The MB temp reads at 32c/89F. My room stays pretty hot too. I am getting this all from Asus Probe, a program you should have got with your mobo.

Edit- I should add, I also have Rain running when I am doing these temperature readings.

Variable, sorry about that, OuTpaTienT is correct, HS=heatsink and RS="Rat Shack"... and I didn't exactly trust that figure either. Still, it gave me some concern, read, almost a heart attack.

chipbgt, can you imagine I forgot that I had that software on their CD? Ugh...

Anyway, I installed it. Came back telling me the CPU ran with 52C and MB at 30C. That's with the case fan in the front. And running SETI (still haven't installed the other software - yet) for now almost 48 hours straight.

I can't easily tell you what mfr. made the heat sink. It is a massive aluminum affair, with fins, splaying down in an arc from straight up at the fan to almost horizontal at the side; one central fan, recessed.

I will look into the Golden Orb...

Installed Rain, dropped temps by about 3C.
