Hello,

I'm looking for a DC Axial cooling fan that is 80mm x 80mm x 25mm (could be 30 or 40mm too, the thickness isn't as important). The voltage could should be 12V, although 5V or 24 would work too.

One of the criteria is that the fan be constructed of all metal. This includes the frame of the motor as well as the blades/impellers.

Does anybody know of a source for these type of fans. I have tried Evercool, but have not heard back from them as their headquarters are in Taiwan I believe.

Thanks Mike

Why metal? Screen both ends for the frequencies you're worried about; Metal parts won't stop emp/emi/etc. If you're worried about thermal effects....open an "all metal" fan and enjoy the various polymers inside (wire insulation, baffles, stringers, spools, etc., etc.)
