you *need* the external air, as you say you leave the windows closed and it
gets far to hot, you need to change that hot air out with external cool air,
so you need some sort of secure way of doing that
in winter the problem will still be there really, your machines should be
able to take the beating though
i run 2 machines in my attic, which can get reallly hot, i havn't had any
probs as yet though
pure number of machines in 1 room is enough to overheat it all
for my own pc i got pissed off with fans fans and more fans, so i went out
and bought some plastic air ducting and an extracter (the kind you get in
toilets) i basicly stick the fan on my window sill and pull in cool air, the
other end of the tube points at my cpu, no cooling problems anymore 
downside is more noise, and a silly looking tube, the fan isn't noisy
really, not copmared to my pc, and i made the tube nice and tidy down the
back of the desk and such, out of sight mostly

Thanks Morgan,
Underclocking is going to be one of the things I will try then (although I
am a bit unwilling to do it
You are right that it is physically impossible to have cool ambient temp if
I can't get rid of the build up of heat in the enclosed space somehow. The
energy has to go somewhere! I am also thinking of water cooling my most
noisy and hot rig (Dual Athlon MP) but I think the water will still dump the
same amount of heat back into the room, the heat just won't magically go
away with better CPU cooling scheme as they still have to go somewhere.
I guess one of the "Out of the box" solution may be to try to install
security windows grills so I can have windows open all the time.... but then
I will get funny creatures sneaking into the flat as I am facing the street
on ground level.

I think one of my second option is to put some small 12" desk fan around the
cluster so even they will be recirculating and blowing hot air but the air
will still be cooler then the heatsink and I hope they will bring the core
temp down by a bit. as at the moment the hot air around the cluster isn't
going anywhere too far without air flow. But that won't solve my problem of
sweating like a pig , I think I will somehow think of a way to keep the
windows opened securely

been there done that, washed the t-shift.....
it does help the pc's a bit, better than nothing i must say
