water cooler fan in my computer room

Question

Is using water cooler fan in my computer room HARMFUL for the internal parts of the computer system?

Answer 1

An evaporative cooler can be if it causes the humidity to rise too high (above 60% or so). If humidity is not too low in the server room (20% will cause static generation to increase) then you should consider using refrigerative cooling instead.

Remember, if you start controlling humidity -- very low humidity can cause static-charge related problems too. And a fluctuating humidity might lead to condensation related problems.
