Adapting a 120mm fan for CPU cooling – Randy Jarois

120 mm

I wanted to overclock and still keep aircooling. I decided on a Thermaltake Volcano 7+ cooler, since it was of one piece construction. I then purchased a Sunon 120 mm fan for case air circulation.

Then it came to me: Why not make that fan my CPU cooler fan?

I pondered the thought for a while. One day while I was in the hardware store, the idea came to me: It was a 4″ to 3″ steel duct reducing funnel.

Duct 1

I got busy with my Dremel and started to hack. I am a machinist by trade, and some of the best things I have made were, well “shoot from the hip” instead of having strict plans or drawings.

Duct 3

I modified a 120 mm fan grill to attach the fan to the funnel.

The photos of my CPU fan mod speak for themselves. I am overclocked @ 3.38 GHz with stock-like temps – 43C. I am going to try pushing the MHz to see how good my “monkey mod” is.

I didn’t run any sound measures, but to me, my 120 mm fan is a LOT quieter than the Thermaltake running at 6000 rpm.
