You can buy a integy heatsink which has a strip of aluminium attached which points the fan at the endbell to cool.



might pick one up

Integy also makes another one like this, but with the mounts on the top. They are very nice...you can even mount two fans on them if you want. Once you change to an aftermarket fan, they are perfect!

One last question: Is it better to have a fan facing the heatsink or the endbell? Or both.
Good feedback, big help.

Best place for the fan is blowing air into/at the endbell.

you are talking about different types of fans, heatsinks...

But think about: Where does there air go in the motor? Where does it leave the motor?

I think, the air goes in at the endbell and leaves the motor at the can. Am I right?
So than you should blow air in the endbell and help them escape from the can...

I think, 2x40mm fan will be the best...

The heatsinks made of alu are not the best. Is there any heatsink of copper?

Sucking air away from the endbell is very inefficient without a shroud. So blowing is better....

Yes copper is better for heat transfer, but what about the weight difference. Hence aluminium is better and the heat transfer isnít that bad with this material....

Yes the GTB fans are a joke, but I think the Novak ones we're talking about ehre are the black plastic ones. Slightly smaller diameter but thicker. They are heaps better than the GTB ones.

The AE one looks the same, but it comes with the Rx connector already fitted. They're nice.

Now I use a 40mm cooling fan and boy this baby can blow some air. I used a 3-racing heat sink take those crappy fan out and just use one screw to hold the 40mm cooling FAN works like charm.

When you buy a fan, are buying a 5v or 12v fan?
