Can a case fan be used for HSF?

My AMD 2100 XP HSF was starting to drop below the minimum RPM thresholds and the CPU heated up during these time. I was starting to get instablity when the CPU hit 64 C.

I have never replaced a heatsink before so I wanted to try and just replace the fan and see how it goes. The heatsink fan size was 60mm, the only 60mm fan they had at my local computer store was a 60mm Case fan.

I put it in and my CPU temp is a steady 40C idle and 2 or 3 higher when under load.
The RPM of the fan do not seem to be regulated by the MB even though I have attached it to the CPU fan header on the MB. The fan is a steady 4800 RPM or so.

Question - is there anything wrong with what I have done? Should the fan RPM be regulated by the MB?

Kind of green.

- thanks

Is the fan 2 or 3 wire? Your bios should have an option to control the fan speed according to CPU temperature...

Most motherboards don't support fan adjustment natively. You might try SpeedFan to accomplish this, however.
