Yeah Racing 40x40x10mm Tornado High Speed Cooling Fan
Surprised at all of the negative reviews, mines been great, only ran at 6v. Quieter than my 30mm at 7.4v - that thing screams and moves less air. 30mm fans are really pointless unless you don't have the space for a 40mm.
I've been using this for 4 months, no issues whatsoever yet, maybe it only likes 6v.
The people who had bad luck, why not return it?

Works as described on 8.4 volts Moves alot of air for it's size.

I'm glad I'm not sitting next to it while operating. it's very loud. I wont be able to hear it over the sound of my 700 class helicopter, but it's going to keep my ESC cool, that's for sure.

Yeah Racing 40x40x10mm Tornado High Speed Cooling Fan
Unfortunately, I bought 2 of these. The first one, the fan blades shattered themselves. Thinking it was my fault, I put in the second one (backup fan) and the same thing happened. These blades are junk. I usually don't like to write bad reviews but because of the money wasted, it was warranted.

Installed one on my RC car, ran great for about 30 seconds and quit. Emitted an odor like melting plastic.
Should have known better. Other Yeah Racing products I have purchased have failed prematurely.
