HobbypowerAlloy Heatsink w/ 5v Cooling Fan for 1/10 Car 540 3650 Size Motor Purple

The design could be a lot better on this but it does help. The first issue is that the fan is pretty weak. The second issue is the spacing of the fan to the heatsink. I put a good fan on this but the air flow was still poor. The fan needs to be spaced farther away in order to get a good volume of air flowing. There is a huge improvement by spacing the fan another 4mm away from the heatsink. You will need longer screws and some spacers. I had some extra 4mm spacers and longer screws laying around.

Chinese fan, works well for the $6 I paid lol

Both arrived with only one mounting screw in the fan not even tight. Only 2 mounting holes line up with the fan. Very very cheaply made. As far as keeping the motor cool it works good. My motor was about 10-20 cooler. The only issue if your jumping/bashing it pops off. Running it on a castle 1/8 2200kv motor in a traxxas emaxx 3906

The media could not be loaded.  A real great buy at the price couldn't beat it not only that is a real great product I bought it A1/10 scale and I use a 1/16scale traxxas erevo 4×4 brushless vxl3m I bought it bigger so you can squeeze it to fit snug tight and then add glue

It works well keeping motor cool, I own a 2wd slash. The motor is a castle creations 5700kv and gets quite hot when punching the throttle. I can run 2 packs back to back no problem fitment is an issue and took some finegaling to get it to seat right. There about 1/4" of the motor that isn't covered due to transmission case. With a metal hop-up transfer case it would fit no problem.

4 solid days of running the fan is starting to make noise

Little fan works! Missing 2 screws on the housing though.

The only thing I don't like about this heatsink is it is very loose fitting on every motor I tried. If you buy this, you will need to shim it with aluminum foil, or epoxy it to the motor.

静かに回るので良いですね効果はまあまあですが無いのとじゃ違いますねかって損はなし

安いんでどんなもんかと半信半疑で購入取り付けにはやや緩いアールでしたので手でちょいと曲げます、受信機の空きチャンネルにコネクター繋げば静かに回ります。これで冷却に効果有るならコストパフォーマンス最高ですね、もう一つ欲しいくらいです、最購入しようかなぁー、あとは耐久性だけです。もしかしてコレ買いかもしれません。ブラシモーターお使いなら540、スポチュンクラスのモーターにジャストフィットします、お使いのユーザーにオススメかもしれませんこのまま壊れずに作動するのを祈るのみですねリピートしちゃいました！こちらの商品は受信機電源ですのでファン自体のパワーは７Ｖ〜以上のファンに比べると風圧が少ないのが難点だと思いますが、冷却効果にその差が出るのかわかりません。しかしないより断然良いのは間違いない、しかし現在値段上がったようですね、残念です。

ファンが全く動きません。ファンを外してアルミのみで使っています。

商品自体はいいです。色を選んだのに違う色が届きました。自分はピンクを選んでブルーが来ました。糞です。
