Weird Temp Readings

[Collek]

Good day everybody.
I was wondering if a 39 degree Celsius reading is normal for a NON OVERCLOCKED Celeron 667?
I recently downloaded Motherboard Monitor 5 and this is the temp readout - (default 667Mhz) 39 Celsius (idle)
48 - 51 Celsius (full load)

I managed to get to 800 Mhz@80/40 with the default 1.65 voltage but i get a 52 celsius under full load! So i brought it back to its default 667 Mhz speed.

I think there is some kind of problem with the temp. sensor because that is not (i think) the normal temperature for a non overclocked cpu, especially when Intel recommends that i dont exceed 45 degrees celsius?

My rig - Celeron 667 Mhz
Original Heatsink and Fan (No modifications whatsoever)
Asus CUV4x-C with PC 133 128Ram (one stick)


Thanks for any opinion or suggestions you can give on the matter. (and yes, Im a newbie!) :D

Well, you're in the Philippines. :) You have to remember that the biggest factor in your CPU temperature is your ambient temperature. Even with some kick ass heatsinks like a Thermoengine with a Delta or a Glaciator, a CPU will never go below the ambient temperature. Good case air flow can break even the absolute best heatsinks.

And I thought Intel said that their procs shouldn't go above 70 or something like that. I could be wrong, though...

Well, im sitting here in my room and its around 31-32 degrees Celsius. The temp reading is now 40 degrees celsius and all im doing is typing a document and listening to a cd!!!! :)
And did i mention that i removed the case cover? just in case something goes up in flames i can douse it with the fire extinguisher. he he he . ahhh the things people do for a few more fps ........:D

It's 70 or 80°C that's the max for the celerons. But, if you even hit 50° I'd be worried. The Intel's can really take a beating in the heat department, but it's not exactly good for them. Cooler is always better. I would definately try a new heatsink. Lapped is even better. Replacing the thermal pad with some quality themal grease would do wonders too. I ran my cell 800 up to 996 with a lapped Intel 933 heatsink, with the fan off of a 1Gig Intel. Do yourself a favor and get a good HSF, and use some really good thermal grease (Arctic Silver II, is what most people around here use).

Thanks for the advice.
So you mean that the readings are correct?
I looked at the heatsink and the cpu and it seems that only a small portion of the cpu actually touches the heatsink! (DUH!)
the middle part of the cpu has a raised square portion that touches the heatsink and this is where i should apply the thermal grease? thanks for the advice. ill go scouting for a good fan and paste tomorrow.

There's a way to calibrate the thermal diode of your processor to make it as exact a measurement as possible...http://www.arcticsilver.com/diode_calibration.htm
