Christian AndersenVerified owneron Hot Racing Clip-On Two-Piece Motor Heat Sink w/Fan (Red)

Kind of goofy to set up. Screws didn’t seem to be the right length. You have to be cautious where you mount it in your motor as it’s metal and you do t want it to touch the motor wires. In order to fit it on my pan car , the fan hangs 1/2 way off the pinion end of the motor due to motor wire placement. Not sure how efficient that is…

Fan works great and is easy to install with this mounting hardware. Fan has lasted me almost 2 years.

Hot Racing Clip-On Two-Piece Motor Heat Sink w/Fan great for on road.

Travis BarnsdaleVerified ownerMay 17, 2024on Hot Racing Clip-On Two-Piece Motor Heat Sink w/Fan (Red)

Alright so to be clear here, I am giving it 5 stars because of the quality for the price. If you are looking for a basic motor fan, this thing is great! It clips on pretty well and looks sharp. Defiantly recommend!

What reviewers say

Four verified owners rate this red clip-on two-piece motor heat sink with fan, with ratings of 3 to 5 out of 5. Reviewers generally find it good value and easy to clip on, with one owner noting it has lasted almost two years. The main recurring issue is installation fit: one reviewer found the included screws the wrong length, and another had to mount the fan hanging partway off the pinion end of the motor because of wire placement on a pan car. Reviewers also warn to position the metal heat sink so it does not contact the motor wires. One reviewer questioned its cooling efficiency without giving measurements. Sample size is small.

  • + Good value for the price
  • + Easy to clip on and install
  • + Durable over long use
  • − Screws may be the wrong length
  • − Fan may hang off motor end depending on wire placement
  • − Metal body must be kept clear of motor wires
  • − Cooling efficiency questioned
