Wanted to put this out here. I have the HAF-X Nvidia and the fan is FREAKING LOUD. I'm not sure if it's borked or just that loud, but it's able to be heard over my SLI GTX 470s at 80%! I can't take it, and with fermi I have a HUGE noise threshold, but this is too much. The fan in question is a 120mm Blade Master. (Specs: http://cmstore.coolermaster-usa.com/...roducts_id=380)
I'm looking to replace it with one that is a little quieter but around the same CFM. My question is, the BM is pretty thick for a fan, will any regular 120mm work in the HAF-X VGA duct?
On a side note, if I added a blue Megaflow to the top, would this help cooling, or would it reduce the positive pressure (more exhaust) and lead to my case sucking in dust?
I suspect there is some kind of design issue with the VGA Duct.. you can try lower the RPM, it most likely will help a lot.
by the way i removed mine as i don't see any difference.
