Great fan system. My motor used to get hot to the touch. Now its barely warm. Easy to install and great quality. I recommend buying this.

Burnt out fan on first run with a 6s battery. The mount works great for the ARMA 40mm fan set though. So it makes the typhon able to use kraton parts.

Plug is not compatible with new Spektrum smart battery plug.

Stopped working after 10 minutes. I hope I can get a replacement fan.

What reviewers say

Reviewers report mixed experiences with this blower motor cooling fan kit for the Arrma 6S 1/8 6 Cell. One verified owner found the motor much cooler and said installation was easy. Others reported problems: one fan burned out on the first run with a 6S battery, another stopped working after about 10 minutes, and one reviewer found the plug incompatible with a Spektrum smart battery plug. One reviewer noted the mount fits the ARMA 40mm fan set and could let a Typhon use Kraton parts. Reviews are few and the reported failures are inconsistent, so long-term reliability is unclear.
