My Phenom II 965 CPU uses a max. of 124W, and usually uses 117.60W under load according to CPUID HWMonitor (even thought that's probably not accurate). This seems like alot of electricity as it is, but then I found out that the CPU fan actually uses a fair bit of juice too, mine states "Maximum Cooling Capacity 90 Watts". Does that mean that I'm constantly using 214 Watts on my processor alone? Seems expensive.. Can someone explain how this all works and any tips you have on saving power.
** BTW my computer's usually running BOINC, working on distributed computing projects, I want to continue using it, but don't want it to use too much power..
No it means the cooler has the capacity to effectively cool a 90W cpu.
Since your cpu is actually a 140W cpu your cooler is undersized.
The stock AMD hsf probably cools better.
PC fans use little power like 5W max.
Unless you have a really crappy psu and an old crt monitor i doubt your using more then 150W when browsing the net.
My main rig uses between 117-126W when browsing the net and listening to music with a discrete soundcard and high powered 2.1 speakers.
My case has 8 fans going as well.
I know this to be true because i'm hooked up into a ups that has power consumption software.
