Abit BE6-II and P3 500mhz. Optimal Temperature?

[LW]

I just got this illy Abit board.
Just flashed it to the newest bios etc (Flashes the built in Hot Rod 66 also! Cool).

Running my P3 500 @ 550mhz.

At 500mhz the CPU reads about 90 degrees cel.
At 550mhz the CPU reads about 95 degrees cel.

What's the dangerous temp? (max temp?)

[Spencer]

I'm not certain, but I believe the last time I read the spec. sheet, the max temp. WAS in fact 90 C. Check at Intel's site. With a little hunting you can find the spec. sheet. Good luck.

I just looked at the web site and it is 90 C.

But my CPU runs at that stock.

Am I safe at this 550mhz???

I have 12 fans in my system....lol Im a freak!
Supermicro.
2- 9 cm fans right over the CPU and Vid Card.

Can someone else with a P3 500mhz tell me their operating temp? Should I stop overclocking for now to save myself some trouble? Or can these chip get hotter and not melt?

[MF]

Mine is about 35c with a simple cooling system: 1 combo on CPU, 1 hs on AGP, 1 PS.

What did you use to read temp? Are you sure about temp unit, f or c?

[LW]

My room temperature is very hot to start out with I think my room is near 85-90 degrees now, its hot and humid out here on Long Island New York.

After booting up and running for 15 mins:

I just booted back up and the CPU is now at 83.5 C. I powered on 3 more fans.

I stuck the Heat probe Sys temp 2 on the Green heatsink on the Motherboard. That reads 53 C.

The System 1 temp now reads 34.5 C.

Can this be caused by my room being real hot to start out with??? Im starting to worry now. You guys got me bugging out. The voltages are set right, then temp was the same before and after the bios flash. I transfered this chip from a Dell XPS-T500 I had, there is no fan on the P3 heatsink itself, I need to buy one quick.

I have a Celeron 300a here running at 540mhz, and I have a modified radio shack thermometer courtesy of http://www.benchtest.com/thermometer.html .

I have the thermisor placed directly behing the core of the 300a, and on full whack running RC5, quakeIII etc, it hits 52-55 celcius.

With the probe on the heatsink it hits low 30's flat out.

How hot is the heatsink to touch? If it was running at that kind of temperatures then I think it would be crashing/rebooting/etc.

I think something is wrong with your readings, but be careful before using that chip. 90 C is way too hot for a P!!!, should be well below that.

You gotta be taking farenheit readings - 100C is boiling point!

if it's 90-100 in the room then you must go through a lot of deodorant!

[Target]

OH MY GOD...... for SURE you need a fan on the PIII heat-sync!

Some Dell cases didn't have one on them, but they had a fan mounted right in the back of the case that blew cool air over the CPU heat-sync.

GET A CPU FAN ASAP!!

For sure having a hot room doesn't help, but ****, no fan on the heat-sync is absolutely the majority of your problem!

[LW]

I just loaded up Kingpin on my sisters Dell XPS-T450 P3 450mhz machine and now that **** is running real hot too, but the dells have a windtunnel over the cpu and a fan behind it suckin the air out of the case.

I just moved my dual 9 cm fans over a little and I think it's cooling off now. The cpu reads 63 degrees cel, My room is now 80 degrees F, o yeah my room was real hot cause I had my door shut I was smoking (cough cough cough) cigerettes. http://sysopt.earthweb.com/forum/smile.gif So I didnt want it to reak up the whole house.
I think I created a dead air zone around the cpu where I had the fans before.

Im gonna leave the system on for 1 hour and post and give temp readings.
They are now:
Sys 1: 33 C
Sys 2: 48 C
CPU : 64 C

It's been 1 hour.

Sys 1: 34 C
Sys 2: 49 C
CPU : 65 C

Im gonna go out tonight and buy a P3 heatsink fan. - Any recomendations?

About 20-30 buks correct?

[Target]

Almost any sync/fan combo you can get your hands on is gonna be better than what you had.

Alpha, TennMax, Golden ORB, etc.

Something with dual fans and a large sync would be good.

As it is now, 64-65C is still really hot for your CPU.

[LW]

I am using the built in temperature sensors on my motherboard.
It comes with one cable with a sensor on the end, I stuck that one right inbetween the heatsinks fins.
There are 3 temp readings:
System 1: 37 C.
System 2: 67 C.
CPU : 89 C.
Using Winbond Hardware Doctor with the Abit.
And also the bios reads the temp in C/F so it is C.

Which temp is the probe? System 2?????

[Target]

Here is the link to temp specs for all PIII CPU's.

You have exceeded their maximum temperature specifications and ARE in danger of burning up your chip!!!!
http://support.intel.com/support/processors/pentiumiii/thermal.htm

That is really REALLY hot for a PIII if your temp readings are correct, and you should NOT continue to run it even at default speeds at that temp.

Double and then triple check your cooling, the heat-sync mounting, etc., the voltage you are using, and so on. Let me repeat, if your temperature readings are correct, you are running on borrowed time.

As for the probe (thermistor) you mentioned, that should be system 2......which incidently, is also exceeding specification.

[LW]

Im gonna power down my CPU for 30 mins.

Load it up go to the bios and check the temp readings when its cold.

I think something is wrong, I doubt it is overheating.

And why is 67 degrees cel. for the temp probe hot if its sitting right on the P3's heatsink?

[Spencer]

I have the first BE6 mobo and it doesn't offer a CPU diode temp option. I do have the temp. probe between the heatsink and the P3 PCB as close as possible to the core/heatsink contact. The temp. runs right around 37-41 C (72 F room temp.) with the system temp. being 25-29 C. It could be that you have too many fans and you're not getting the heat out of the case, but actually just swirling it around. You should have a flow of air through the case. I personally have a Antec Full Tower with 4 (80mm) fans. One in the front bottom, 1 on the side blowing across the AGP/CPU, and 2 in the rear exausting. I also have a Tennmax CPU cooler with two 50mm*20mm fans. I hope this info. helps. Good luck.

EDIT- What were the temps. before you flashed the BIOS? Are they different now?

1. check your temp reading from Hardware Doctor and BIOS.
2. check your cooling system and airflow.

If nothing helps, you shouldn't use it until you can find solutions.
