Temperature Problem

[AntmanMike]

Hello. My BIOS reads my temperature as 82F, while Asus Probe reads it as 122F.

The motherboard isan Asus P4T-E
the processor is an Intel Pentium 4 1.8A (Northwood)
I am using stock cooling.

The heatsink is level the CPU, and Arctic Silver 3 is the interface material. Windows 2000 has been crashing a lot, also. Which temperature reading should i trust? Help?

well those socket thermistors CANNOT be trusted, and as far as i know all ASUS boards, adn temp progs are way off also. Try using SiSoft Sandra

Considering i said PENTIUM 4, its not an insocket thermistor, its in-core. Lets see. The BIOS says the CPU temp is 82F, MBM5 says its 82F (And it says the CPU is cooler than the MB), Asus PROBE says the temperature is 122F, and SiSoft Sandra says its 80.6F.... I think PROBE is lying to me.

Yes it is. I do not trust ASUS Probe. ASUS is well known to be off on reading's by about 10*c. I use MBM5, and it can be adjusted.

I dont know if this would affect the temperature much, but I dont have an ATX12V compatible power supply, so i rigged up an ATX12V connector by cutting up an ATX Connector, then attaching the 12v rails and the grounds. Here are some pics:

The molex the rails come from.

When I got my 1.8a a few days ago, I took some readings with the stock heatsink just for the heck of it.(The stock heatsink is not the AVC Sunflower, but the same one you have)

With the CPU at default and the case ambient temp at 77*F

I had a temp of 82-87*(idle) confirmed with a Digital Doc 5

Running Folding@Home and Sandra Burn I got 96-105f(load)

The 1.8a puts out roughly 50watts at default.

-My case has excellent airflow-


Ive had two asus mobos and only my P3V4X reported the temps accuratly....the other I had was way off.....I'd go by the Bios if your using an Asus Mobo, maybe buy a Compunurse or a Digital doc

PS I hope my Celsius conversions are correct, I always take readings in Celsius...C'mon Mike lets start using Celsius

As you can see from my pics, im not using a case :/ I also have a Sunon 80mm on top of the stock fan. Beleive it or not, more air goes thru (i know because i can feel it.)

SilverSinkSam,

I use the P3V4X and I don't think I get a good reading on temp.
How did you check and compare your temps?
Thanks.

craig, Most P3V4X's dont report it correctly....I guess I got lucky, what I did was compare it to the Digital Doc temps....I had a temp probe bored into the heatsink itself.

You can buy a Compunurse for about $18...

You can also compare the Asus probe results to the Bios temps

Sam, even though MBM5 reports 78F on an 144mhz overclock, at 110mhz FSB, when i boot Windows 2000, everything starts crashing and recrashing continually, even though the temperatures are still minimal. I tried disabling RDRAM Turbo, and i raised the PCI Latency from 32 to 36. Help?
