939 CPU Fan Replacement Question

Vario · Jan 5, 2007

What size fan do I need to replace my 939 cpu fan?
I dont want to replace my heatsink, as my cpu idles at 27*c, but I do need a new cpu fan as it is making some crazy noises.

err...what cooler has it got on it, if not sure can you post a picture

Its the stock AMD 64 Venice one. I ended up ordering some $5 Coolermaster fan+heatsink combo, hopefully the fan will mount on the existing heatsink to save me some effort.

The stock 939 heatsink fans are 70mm. The $5 Coolermaster heatsink has a 80mm fan. A difference between the stock and the $5 sink is the cut of the fins. The stock one will flow air out of the sides of the socket while the other will flow air out the top and bottom of the socket. With my board the air flow of the stock cooler is best imo, espically since I installed the heat pipe which needs the side out air flow. I know Coolermaster makes a few 939 coolers, but the less expensive ones have air flow like this.
