Hi!
A little while back i built myself a new rig and put it in a HAF Xv2 case. Everything was great and quiet for a few weeks until something started whining.. I found that the accompanying 200mm top vent fan: Cooler master A20030 was to blame. I thought perhaps there was something off with that fan, so switched it with the other identical side panel fan that came with the case, but that immediately started to whine the moment i turned it on.
Both fans are silent vertical, but whine loudly horizontally in a vent position but when flipped to draw they are silent. Thus deducing it is a bearing issue when the blades are hanging from the mount.
I'm perfectly comfortable with leaving the A20030 as a side fan and a spare (as i took the top one out), but i would like to fit some fans back into the top so my questions are:
1) Is it usual for horizontally mounted fans to wear out that quickly/whine immediately? (the A20030 apparently has the same code as the Cooler Master MegaFlow 200)
2) If 1 is yes, are there any fans with the blades inverted? Since it appears all will have the blades hanging from the mount when placed to vent.
3) Having reviewed quiet fans I was looking to get some Corsair AF140s, but cant seem to find a bracket to attach them to the 200mm socket. Unless you just use the cpu heat sink 140mm -> 200mm adapter?
Many thanks for your time
