I suppose to build a small dehumidifier, but I am narrowing the question down into its logics.

I have relatively powerful computer fans, water cooling radiator and some metal tubings. With the idea of compression and decompression I think air would do the job better than the original liquid coolant in the water cooling system.

The idea is to generate pressured air flow into narrowing tubes, and have it bursting out inside the radiator. Assuming ambient temperature around 25 degrees and above 60% relative humidity. (usually around 80% in my area but let's generalize it a bit)

My question is, could this lowers the air temperature below dew point? And how effective is it?
