Hi,

I recently decided to replace the cooler in my Fuloong 6014, which had
been running almost continuously for > 2 years.  The original cooler had
started to make strange grinding noises and the housing was also getting
quite hot recently.

I successfully used this part as a replacement:

Datasheet here (name of part: GM0503PFV2-8)

As this part came without any plug, I cut off the wires of the original
fan and soldered the old plug to the new fan.  The yellow wire was not
provided by the sunon fan so I left it unconnected.

The new fan makes quite some high-pitched noise, sounds like much more
than the 20dBA on the product specification (maybe hitting a resonance
with the fuloong enclosure?).  I won't recommend it for anyone who has
to sit near the Fuloong for longer periods.  Though the cooling is now
very efficient.  Harddisk temperature went down from 50 to 41 Celsius
with the new fan (recent weather changes may be a contributing factor
:).

For a less noisy solution maybe it'd be better to purchase the Sunon 12V
cooler (e.g. GM1203PFV1-8) which will then run much slower on the 5V
provided by the Fuloong's fan connector (but might overheat?).

cheers,

David
