I guess we would like to install the fan even if Actcom will install
additional refirgeration very soon.
This will give us additional "warranty".

First, what kind of fan do we need?
The disks at iglu are located in bottom of a tower box, in a following
fashiion ( sorry for a non-comprehandable diagram ):

( area marked with Ms is the motherboard )
The mirror disks are mounted vertically, very close one to another.
They should generate pretty big amount of heat.
By installing an adequately powered fan in area marked with Fs, we can
protect the system from boiling itself to death.
I checked fan prices with Excellnet. They do not sell those big fans come
usually with ATX cases, but rather they do sell small fans, appropriate for
cooling CPUS and single hard drives.
They want 22$ for a 3 fan pack, which is to be installed into a front panel
of a desktop system.
The pack is sufficient for a one high-speed hard drive.
We can opt for 2 such packs and hope that this will be enough.
However, I think that we"d better look for big ( 4+" in diameter ) fans,
that are
usually sold with server boxen. The question is: can somebody locate store
that can
sell such a fan?

Not known to me, but maybe Ilia or Guy will know.
