Northwood 1.6A heat

[home skillet]

I just finished building a system for my brother with a P4 1.6A and Shuttle AS40GT SiS 645 mobo. I use the stock cooling fan that came with the CPU (retail box).

Everything went fine. Win XP installed fine and its still running good w/out any crashes so far. However I checked the CPU temp in the BIOS and it said 45 deg celcius. This was after the comp had been on a few hours and I rebooted.

That seems a little high to me. The CPU fan is only spinning at 2400 rpm. I checked the installation and it looks good. I installed the heatsink exactly according to the instruction that came w/ the cpu. I am not too worried cause everything is running fine but now I am very reluctant to try overclocking it.

Is this normal? Do I maybe have a defunct heatsink or fan? The case is an Antec SX830 and gets good airflow from case fans. Thanks

Hey same here.

I got a 1.6A and an Asus P4S533 motherboard. I'm using the retail heatsink/fan that came with the processor because I heard it performs quite well for a stock.

Accorinding to Asus probe my temps are 40c (for cpu) and 30c (for mb) and the cpu fan runs anywhere between 2400-2600 rpm.

I was wondering if that's normal?

It should be normal the fan will scale up and down up to arround 4000 rpm as your cpu get's hotter.

Anything ~40-50C is about right with the stock cooler

Draser have you updated your ASUS probe l8ly? because the version that ships with the mobo doesnt work it locks the CPU reported temp @ 40C Still if you have got the newer version your getting some good temps for stock cooling

Here's an idea...mod the fan a little bit. Instead of drawing the power from the 3pin header, give it juice directly from the 12VDC line on a molex connector. If you got an extension piece 4 pin molex, this mod is a breeze. All you gotta do is cut the red wire near the 3pin connector, leave the black and RPM wires untouched. Then, splice the red wire you cut, onto the yellow 12V line of the molex. That will deliver full power all the time + you still got RPM monitoring so you don't have to worry about the fan failing...

Noise does become a consideration at 4000rpm though, if it scales up that high. IF THE FAN IS AT MAX SPEED AROUND 2600RPM, IGNORE THIS!

What's the latest version? I check Asus website and downloaded version 2.14 something, but when I got home I saw mine was 2.16 something. So I believe the one that came with the mobo was the latest unless someone can point me to where I can get it?
