Tornado Plus Aluminium Case High Speed Cooling Fan 30 X 30mm / Yeah Racing/YA-0472BK

Update: After having used these for a bit now I can say they are high quality worth ever penny 30mm fans that lowered my motor temperature by 50F. The ability to run it on a high voltage BEC is great and necessary. High quality aluminum housing to boost the heatsink and 2 of these on my Yeah Racing 1/8 twin fan motor heatsink using HV bec has changed my average motor temp from 160F to 110F and has allowed me to gear up my arrma kraton 6s several teeth if I want to. Went up to 19t on 6s and WOT the whole 5Ah graphene in a giant grass field. Topped at 165F at the end. Was only a 6 minute run because I was pulling 90amp average and up to 195.4 amps max. The HRB 6S 5000mAh graphene 100C came back the warmest it ever has after that run, 120F most runs it's never near that hot. Most regular lipos would have puffed or came back burning hot after that

Well built. Great fan. Moves a lot of air. Quiet too.

best fan Ive ever had ! Last a long time
