since running a heatsink actually makes the motor hotter by covering the cooling slots and preventing airflow, wouldn't the heat taken away by the fan be cancelled out by the heat being "generated" by the heatsink?

that is of course if you believe me when i say a heatsink makes the motor hotter... it's a matter of opinion i guess

I find it a bit silly that so many companys would make heat sinks if they dont do anything... and you would think by there name that they would work. But i guess on cars like the tc3 were airflow isnt the best they could be pretty bad, but on other cars like the losi or mission were airflow is good a heat sink could really work well. Another thing to consider is what kinda of heatsink it is. I have an integy one that has lots of holes in it so that air can still come in but the heat sink can still take a fair amount of heat away from the motor. However i think a fan is the best meathod, now i just gotta find a place that sells them...

Well, heatsinks work as long as they are in contact with the motor surface. The addition of the fan was not to cool the heatsink, but to cool the brush hood area. With today's motors and hi-po batteries, ANY helpful cooling will be benefitial.

I was told many times that the holes in the side of the can aren't there for cooling benefits, but instead to alter the magnetic field off the can. Just what I was told. I'm always a skeptic, though.

Does anyone know the natural airflow direction motors? Does it normally go into or come out of the endbell?

Speedo..... Use a "Y" connector. No big deal.

You could probably make this like the Reedy one, just atach the fan so it is hanging off of the side.

Greg, what you had seen was the first prototype that we had used at the Reedy race.


As for how they work, very well. If you are melting brushes or unsoldering them this will help out greatly!!!

Hi -

I thought I'd bring this up....

So, does anyone know of a source were I can get just the small fan without paying an arm and a leg?

It's already tough to find small fans, but in a 4-6 volt range is pretty tough...

If anyone knows of a good source please post the website here....

Regards

Dave

The Comp USA near my house had a whole box of them, old 5 volt fans that came out of discarded lap tops. The repair guyes had them. Hank also has them on HT.

I got mine from the computer store. The fan is for the VGA cards.

guys, you want to use 5volt fans, as many of your may know, ANYthing higher is basically useless. do some research on google for Sunon (the brand) 5v 40mmx40mmx10mm fans.
