Use a can of compressed air to clean the dust from the all case filters and fans. Blow out all dust from all the heatsink and fans, especially those on the CPU.
Next, run the computer with the case opened. Observe the CPU fan. Is it making all the noise? Is it struggling? If so, maybe it's time to replace it. What are the temperatures now?
There are many factors that influence temperature, but in a room temperature environment, the P4 should idle well under 50
My computer has always seemed to be running at high temperatures as I can feel the room heat up and the fans always running so loud.
I downloaded Speedfan as i needed something to adjust the fan speed as the sound was getting unbearable.
My "Temp2" sometimes reaches 75C and my HD 45C.
Are these temperatures normal? What is a safe temperature for my computer to be running at?
System is as follows:
Pentium 4 3.0GHz CPU
Seagate 80GB harddrive
1GB DDR RAM
