9cm fan- 2600rpm, 0.17A, 48.48CFM

I tried running them on a spare PSU. They're very quiet considering it flows so much air. It's coz of the solid alu frame. No vibrations so it's nice n solid with no vibes.

After taking off the old hsf, I gave the mobo a good blast with the good ol can of air. The mobo now looks good as new n ready for the new hsf.

I get all my cans of air from Ikano ACE.  They always run out of stock though. The minute I see new stock I will sapu a few cans n keep. U can get ACE brand or Ambersil brand. ACE is rm20, AMbersil is rm40 but has twice the contents.
As for the Freezer64 Pro, it's very easy to mount, just put the thing on top n clip it on. There's a very important thing to check 1st though. U must make sure that the clips on both sides are properly seated on the 3 plastic prongs then only u pull the lever to lock it.
