Innovateking Motor Cooling Fan 28000RPM 8.5V 540 550 Motor Heat Dissipation Metal Cooling Fan 1/8 1/10 1/12 Scale RC Car Accessory for 540 550 Brushless Motor

The media could not be loaded.  So far would be 5 star If it was cheaper. literally moves what must be 10 times more air than the crappy hot racing fans that come with the heat sinks and esc cooling fans I have purchased. Also I just upgraded my rc and in doing so have flipped and crashed ect at least 15 times in first two runs pretty violently I might add. Getting use to the new power and handling of my new set up crashed alot as stated and so far fans working perfectly fine will update if this changes. At least these move massive amount of air only downside I see so far is they are loud but does bot bother me just like a race car the louder the better lol....You know you have some power under the hood when its loud. Fyi if your running fans you should be protecting them in some way I use a breathable mesh dust cover for my rc..if you break a blade and provided no protection from debris it's not the fans fault. If you want you can use the waffle looking dry wall tape cut to size of fan motor criss cross two pieces . A dab of silicon on each corner will hold it in place over fan acting as a cheap shiled from small debris like tiny pebbles ect or get a dust cover for your rc chassis.

After my stock fan died I bought this one and I'm glad I did. It's powerful for the size and moves a ton of air. Hopefully the internal bearings can handle that without burning up.

There may be nicer on the market.. but this thing like a mini jet engine! You can really feel and HEAR the airflow from it. The aluminium casing being cold to the touch after a 15 minute run cooling my 3s lipo powered 540 is really a testimony to the cooling power and quality of these.Only reason for 4 star is because i feel the wire being color coded is better than little markings on the plug.. I CANT READ

Only gave it 4 starts because it does NOT come with screws to hold it to the heat sink and the wire is a little short. HOWEVER, this thing sounds like a min jet and blows super cold air. Did a great job of cooling down my rc motor.

At first try the fan is awesome. Lots of power and fit perfectly on my integy heatsink. Wish it had a cover on the blades but that might restrict air. Hopefully this doesn’t risk the blades falling out. Had that happen to the integy fan. Good price, $17

Great fans. One of the best fans i have ised so far. Bash extremely hard in mostly dirt. Still no broken blades and going strong. Have never taken off to play in water and still going strong.

Don't add too many, you might turn the rc car into a quad copter

Very powerful fan hasn't bog down when you move it around not extremely loud when you can hear
