izzit my system temp normal??
idle 40C, load 44C.
and how to prevent dust in my case and fan because my com power 24hr per day for bt dl.

Your system temperature good.
Use fan filter lo.

Threadstarter, mind to tell us what kind of system are u using?

well this is not bad

my system spec is p4 3.0 prescott.1 gig ram dual channel.1 seagate 300G and 1 seagate 80G hd.onboard sound. 1 dvdrw and 1 cdrw.graphic card ati 1800xt. all at stock and none overclock. psu coolermaster 430w.

and where can i get 120mm fan filter??

Pentium 4 3.0 prescott, is that LGA775 or Socket 478?

By the look on you're gc, i think it's LGA775 right?

The processor, what model number?

530?
531?
630?

If 530 using stock heatsink, then the temperature is considered good already loo...

prescott 530 LGA775 using coolermaster hyper6+.

If it's prescott 530 using hyper 6+ at 40celcius idle, then that's hot...

I also have one Pentium 4 530 rig in my room, and it's also using Hyper 6+, but i've managed to get 36celcius in idle...

Maybe u should recheck on how did you fix the heatsink on the processor...

Or, maybe u should change the thermal paste to Arctic Silver 5...

Ohh, and before i've forgot, my 530 in full load with using hyper 6+ is only at 40celcius...

no no shawty. wat i means is my chassis temp.
my pro also 32 at idle and 40 at full load.
hehe. u misunderstand wat i means. summore i got 1 120mm fan intake and 1 120mm fan exhaust.

Then the temperature is normal, if you want lower temp you can use a better intake and outtake fan.

thanks for the help guys.
