How to measure fan size?

Hey, I really need a new CPU heatsink/fan, as the one I have atm roars like a lion. I measured from one end of the blades to the other end on the opposite side and it was about 68mm, but I don't know if that is correct. Do I measure the blades (both sides) or the entire thing from end to end? The heatsink/fan came with the CPU and I bought the CPU here:

Any help?

  1. The stock coolers can be quite noisy, have you got cool n quiet enabled?

    How much can you spend on a cooler and what motherboard do you have??
  2. i have this rosewill cooler on an athlon II. its cheap, simple to install, and comes with a fan controller. works pretty good for the price also

    i have the CM 212+ for my phenom II. its a tower cooler, you need to install a backplate but it works great and you won't find a better one for the price
  3. You measure one side of it. Specifically from the center of one hole to the other, on the same side. The fan sizes will typically be something like 60mm, 65mm, 70mm, 80mm, 90mm, 92mm, 120mm. In your case it sounds like you overmeasured by going beyond the holes so the actual measure might be 65mm.

    Hope this helps!
  4. And yeah, the stock coolers for AMD have recently been small heatsinks with loud fans. I would recommend getting a brand new heatsink instead of a new fan since it won't fix the fact that the heatsink is too small. Tom's has recently done a fantastic article on budget coolers here:,2788.html

    The article lists Rosewill RCX-ZAIO-92 as the best budget cooler but unfortunately it's out of stock on Newegg. The others on the list should be fine and far better than the AMD stock cooler.
