GOT THIS FOR A 4TEC 2.0 VXL WITH HIGHER GEARING & USING 3S LIPOS. NICE DESIGN, THE ADJUSTABILITY OF THE FAN MOUNTING HOLES & PLATE IS GREAT FOR PLACMENT ON THE MOTOR. THE FAN ON THE OTHER HAND IS NOT REALLY THAT GOOD, I REPLACED THE FAN WITH A "YEAH TORNADO FAN". IF U GO WITH A DIFFERENT FAN THE SCREWS ARE M 2.5, I WOULD PURCHASE THIS AGAIN---!!!
I can’t believe how well the tiny heat sinks hold on the the motor, I figured they would pop off on the first roll or hard jump but they held fast. The fan cools really well I installed it on my Lasernut stock motor that I am running on 4S because the motor heated up the aluminum chassis pan to a point that it was uncomfortable to touch. The motor was even hotter. With these two little heat sinks and the fan the stock motor was no longer uncomfortable to touch after a 45min run and the chassis was just a little warm to the touch MUCH BETTER! 4 stars because they did not include enough screws, they only give you 2 screws to mount the fan bracket to the heat sinks, it needs 4. If you look at the picture you will see only two little tapered head screws are included it is designed so that each heat sink has 2 holes that can be used to secure the bracket. The screws are 2.5mm you will want to have some on hand unless you don’t mind using one screw per heat sink.
The fan and the heatsink work well for a good while and did amazing for cooling. The problem is the fan has no protection therefor debris got in it and broke it. Then burned it up
Reviewers generally report that the clip-on heat sinks grip the motor well and that the fan cools effectively, with one reviewer measuring a noticeable drop in motor and chassis temperature on a 4S setup. The mounting plate and fan holes are praised for adjustable placement. The main recurring complaint concerns the fan: one reviewer found it weak and replaced it with an aftermarket fan, noting the M2.5 screw requirement for alternatives. Another reported debris entering the unprotected fan, which led to failure. One reviewer felt the included screws were insufficient, saying only two were supplied for the fan bracket where four are needed. Reviews are few, and all concern the blue variant.
