Default Question about cooling fans

Do most of you use your fans to blow cool air on the motor or do they pull air away from the motor, meaning the don't blow on the motor they blow the opposite direction.

blow on to the motor

Inside a computer case, there's enough negative pressure to do it the other way around. But in RC application, there's not enough negative pressure.

Well then that brings another question, the Associated dual fans I purchased are blowing the wrong way then. I can't just turn them over because that would pinch the power wires that run into the fans between the fans and the mount. Could I switch the wires in the servo plug to reverse them, I have a spektrum reciever?

No, you cannot wire them in backwards to have them run the other way. The fans use brushless motors and the control circuit in the fan will not function properly. In fact you might even destroy the fan.

Use servo tape to mount them. What you can do with the wires is put a strip of tape from outer edge of fan 1 and make it go accross that base and accross fan 2 base to the outer edge. Then cut out a small gap in the tape so you can run the wires. This will make the wires sit below the fans, but not being pinched by the chassis plate and the fan base. This is assuming your running the fans beside each other like this {}{}

Thanks for all the suggestions guys, I ended up laying a thin bead of black silicone all the way around the mounting surface of the fans and setting them in place. After the silicone set up I put some maching screws and nuts to hold them down. Good suggestion with the tape too, I just have a hard time holding everything on these "luxury" touring cars with double sided tape! LOL!

I have a question, do you use a 25mm or 30mm fan for the motors?

Sup joey, this setup would be the cheapiest and probably the most efficient for 19turn. http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN%3AIT&rd=1

Here's the air scoop I told you about: http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN%3AIT&rd=1 I really can't use them on my LCG, b/c the RX sticks out too far. I'll give you one for free if ya want to try one out. It weighs almost nothing and is clear.

I just ordered on of these double fans from Cool Can Fans. I saw some at the Reedy Race and they looked really well made.
