Cooling the server area - Peltier way - the idea

Time ago I did buy a Peltier unit cooling contraption.

There are many different types on the market, I think mine is a 50W unit already assembled with 3 fans, two for cooling down the
hot" side, and one to push the cold air.

Cooling the server area 2.0

Years ago .. almost 10 !!! I did set up a cooling system for the server area, basically a under stairs area in garage. 

Is time to try to improve the system.
