RE: Keeping node0 cool...

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

When I built (or rather my builder built) my new node 0 in my loft
conversi=
on, I put in a large very high flow axial fan - cost around =A3400 IIRC.
(t=
his is physically quite big too - industrial sized). This has a huge
airflo=
w and is variably controlled by CBus. The extract is at high level above
tw=
o rack cabinets that house all the AV kit plus 4 servers. Inlet is from
the=
north facing front of the house under the eaves.

So far, last summer, it kept node 0 fairly cool - at least as cool as
ambie=
nt outside temp - without the huge expense of AC.

Previously, I had Node 0 in a double cupboard. Temps would soar to ambient
=
+ 20C - which caused a load of problems. I installed a standard bathroom
in=
line extract and ran it 24/7, venting to outside. This was OK and did help
=
a lot but these cheap fans just aren't designed for 24/7 running. I found
I=
had to replace it every year or so when the bearings failed a couple of ti=
mes.

Must get some pics sorted of node 0 !

Paul.
