A simple under clock experiment

I have one computer in a closet. It is a server that is always on. I did a little experiment to see how under clocking the CPU would affect temperature and power consumption.

The CPU is a AMD Atholon 3500+ that clocks in a 2,2 GHz. During the test I had 2 Gb of memory and one Samsung 80 Gb, 2 platter 2,5 inch hard drive (a notebook hard drive).

Speed		Power consumption	Temperature (high fan speed)	Temperature (low fan speed)
2,2 GHz	Load	36 W	52	60
	Idle	26 W	39	40
1,8 GHz	Load	35 W	46	53
	Idle	25 W	37	39
1,0 GHz	Load	30 W	42	44
	Idle	25 W	37	39

I did not modify the VCore anything during these tests, I let the motherboard decide that. My guess is that with more tuning of the VCore I would have gotten better numbers.
