What does INTEL say the safe temps are for a 500e??

[Hardware911]

just wondering what they say are safe for cumines...does anybody know??

idle and at 100% load

i know the lower the better but what do they say

[PrOLiNe]

I read somewhere around 75 - 85 celcius. Dont recall exactly offhand. Download PDF format spec sheet at intel site.

Should be some info here...

I thinks that means safe temperatures for the CPU not to melt. I doubt the thing would actually run stable at those.

Hey, does anyone know the wattage on a p3? I have a 500E and kinda would like to know, for physics class. I've got my professor helping with the equations and such...

well they say use 1.6 on a 500e thats what mines at never had to raise it even at 750...i think im gonna lower it and see if it will reduce the heat and stay stable....

should i do it??? can it hurt it?

so does this mean they say its safe to run at 85c well....i must be reading this wrong...i can melt my gold blocks in there...

am i reading it right?

[PrOLiNe]

I surfed through the PDF. They stated to make sure manufacturer provides adequate cooling to ensure proper opreating temps for the highest wattage chip even if they do not plan on using it to stay within the tolerances.
I do not like the idea of 85 celcius either, but think about the electronics located under the hood of a car. I am sure overclockability would be non-existant.

[Hardware911]

so my peaks of 50 to 52 at 750 arent as high as everyone says they r? at 500 i still get peaks of 42 to 44 so at 750 thats not much higher should i run it that high???

[FS]

Just remember that that's the temp on the silicon. The temp on the surfacec/heatsink or where ever the termal probe is located won't be that high. So if you're actually reading 80°C from your BIOS then start praying...

anyone got any ideas why i cant get my 500e at 667 stable? with my globalwin on it it stays at 28-32 oC, but every time i get into win 98 it finds registry errors and reeboots my machine then it runs registry checker on startup every time i restart, so i cant get into windows...any ideas
I am using a p3 500e on a TMC ti6vg4 mobo with 128 megs of ram running at 100Mhz (host clck -33)

FS: The temp diode for the Coppermines is on die.
So a MB monitor reading of 80c would translate to 80c silicone temp.

Most manufacturers design systems to run at spec-speeds around ~50C.

Any thermal solutions guide I have seen that floats around large resellers and OEMs say you should reckon with ambient case temperatures of 40C - 45C.

They need to be able to guarantee that everyone putting their machine in a "normal" environment (15C - 35C, 5% - 95% humidity, up to 10000/3000 feet/meters altitude) can run their machine at spec speed. The good manufacturers of PC Components generally give warranties ranging from 12 to 60 Months, most of them 36 months (3yr), with memory being the only notable exception (lifetime in some cases).

So you can run chips at higher temps than people here have them at - we overclockers tend to cool our chips a LOT more than a regular user does.

Take the 200 odd PII/PIII PCs we have here in the building - they run at temps of around 40C with a room temp of 20C - 22C, and its winter. In the summer the room temp in some rooms hits 30C when they are facing the sun, on top of that the PC sits in the sun - that CPU is gonna reach 55C, as much as 65C if someone is running SETI (*innocent*) or working actively (fat chance).

But any large office is more worried about the monitors, which cost more than the PC, and a LOT (x6, or x20 for TFT) more than the CPU.
