Monster Pro heatsink question.
 

It says in the description that u can mount 2 40mm cooling fans on it, the problem is that i can't seem to find any fans larger than 30mm, wuts up with that?

Where are you looking? There are many 40mm fans on ebay, or at just about any computer store.

Oh, was looking at Tower and Horizon Hobby:lol:

If you don't want to do ebay - these guys sell 40mm fans for 5v, 12v and up. Click on shop, this at the bottom click F - the next page will have their fans. I'm running two of theirs and need more for another 125b I'm going to be using on a g2r.
