I decided to open up the unit and get more info on this new fan.
Not surprising that Panaflo is the manufacturer of yet another quiet fan. With the vented fan housing and hydro wave bearings, this is one quiet fan.
What exactly is a hydro wave bearing? It's Panasonic's answer to the problem that plagues most sleeve bearing type of fans, axial friction. The hydro wave bearing (HWB) system uses a thrust plate that floats on top of a circulating layer of oil. This greatly reduces the amount of friction, which in turn greatly increases the life of the bearing itself.
Since I had the fan off, I decided to take off the metal housing also. The picture above shows the weird two holes on each corner. Not sure why this was done, maybe TT is re-using left over covers from another application.
Doesn't it look like a Thermalright SLK-800A heatsink, minus the middle cut-out channel for the holding bracket? Either way, this designs seems to work well, so let's stick to it.
A shot of the thin fin design. I moved the heatsink over a black screw to give you a better idea of the whole thing.
I tested this unit on my AMD 2000+ XP running at 1.9Ghz, using BuffaloTech 512MB DDR. At load, it was a nice and even 45C. This was completed after running about an hours worth of Prime95 on torture. At idle, a cool 37.5C, with a room temperature of around 27C.
These numbers are fine and dandy, but the real selling point is how quiet this thing is. The hard drive is louder than the fan in my test rig! Kudos to TT for picking the right fan for the job, I'll be keeping this in my test rig until another unit can top this.
Thanks to Nick from CrazyPC for sending us this sample, give them a holler if you need one! Tell him we sent you and he'll give you extra packing peanuts :P
