For those who deal with their stage,can you recommend some serious stage fans ?

Hi Guys ,

If I solved recently my laptop overheat, I m now looking for some cooling solution when we are on stage.
My band and I play in the caribbean and temperature is sometimes going off the roof and we are looking to invest in some fans that will help us to stop sweating like maniac.
of course, I need something quite transportable, not too expensive and not too noisy.
Something also too powerful might be a problem if something blows too much in our direction.

So a lot of conditions but I m sure one of you will be able to come up with the right solution.

Thanks in advance,

Bviman
