I am considering buying a fan mist cooler, but i am concerned about the moisture from it damaging my computer, Am i correct in thinking about this?

Humidity around the value that occurs naturally shoud not effect your computer. Get a hygrometer and make sure that the fan does not blow in the direction of the computer.

HTH, hillshaveeyes

You are absolutely correct! I have seen some coolers that use heat exchangers (freon based radiators). They usually are for GPUs, but I have seen them for CPUs. That would be a better option.

If you are talking about the large fan units used outside for restaurants I would never use in an enclosed area. Not only would the humidity quickly become oppressive but you have heard of legionnaires disease?

If he is talking about the small home sized units -- we used to have one and frankly, in areas of high humidity it doesn't work.

Our computers get damaged simply from the ambient humidity, but then they are right on the ocean too. We were told not to turn them off if we didn't have to as condensation forms on the mainboard as the unit cools (to which I can attest having replaced numerous sticky mainboards over the years--sticky from sea air that is)

I laugh every time I see fan mist coolers and water spraying misters indoor in Thailand. They DO NOT work because of the high humidity. We are in the tropics not the dry desert.

that is correct. however, even in dry climate evaporation coolers do not work if the air is not continously exchanged.

Thank you for educating me, so the general opinion is that a home indoor fan with a water spray is a waste of money ? I really never thought about the tropics thing and humidity hmm who do i send the cheque for the education

I lived in the Mojave Desert in Southern California for 8 years. Saw a high of 120F=49C. As long as the ambient temp was below 115F or 46C evaporator coolers or swamp cooler worked great but above 115F they were a no go and bring on the frig.

I've never heard of a cooling tower being 'indoors'. As such, Legionaires Disease is not a problem...at all!!!

It is caused by breathing mist containing the bacteria and that bacteria is apparently common in water here in Thailand per this current news report.

Below is cause as listed by NIH

Legionnaires' disease is a type of pneumonia caused by bacteria. You usually get it by breathing in mist from water that contains the bacteria. The mist may come from hot tubs, showers or air-conditioning units for large buildings. The bacteria don't spread from person to person.
