Dear dipzy!
I know what you mean mate.
I had a server in a little server room just near my storage room in the apartment (see pictures below) that run 24/7 with 17 HDD in
A fan was attachet to the fresh air intake at the wall and connected to the computer so at wintertime when the temperature was bellow -25° Celcius I had 0° on the motherboard and 7° on the CPU, no
condensation at all.
