Don't buy these kids toys, I made a serious mistake buying 6 of these to replace the failed fans in my add-on assemblies, I have an hour spent cutting, soldering and installing the fans, to my unpleasant surprise one of the 3 worked as expected on the first build, the 1st spun perfectly, the 2nd spun and dropped the blade after 30 seconds and the 3rd stayed just stand, it goes if i give it a PPL, but otherwise it stays, so 1/3 of them work, poor quality control, don't do it, find something better. I have just ordered 2 5 pack arctic fans.
