Another possibility is to reduce the voltage of the fan from 12 v to 7 =
or 5
volts, I=B4m using stock fan with 2 hd (2.5=94, 10 and 160 gb) on a =
single
adaptor connected to the Qube IDE with no overheat and very little =
noise.

I have my Qube on my room and I can sleep with no problems.

You definately *do* need a fan if your qube is doing any serious work. I =

no messages on the console. After an hour's googling I finally thought =
to=20
check the temperature of the HDD with smartmontools (it's the only temp=20
sensor in the qube). It was 65 degC.

I installed a 2.5" HDD (only one screw holding it, and you need an =

and replaced the fan with a generic 4cm one; it was still too loud so I =

one of those variable fan speed regulators between the fan and the MB. I =

set it to the lowest setting that the fan would still spin up at when=20
booting the qube.

It's almost inaudible now, can be stressed at 100% for weeks and the HDD
never goes above 35 degrees.
