I have got myself a motor fan from Much More. I must say that it's very strong. I haven't really tried it on my car as i am afraid that the amp draw from the fan will slow down my car. Is this true?

If you don't think it does anything then don't use them. Other people think they help so they will use them.
Also, your batteries are not going to dump because you run a fan.
I'm not saying don't use them me myself are using this fans but like I said the cooling effect is very minimal.

But I might try different ones like this RADIOSHACK MIRCO FAN and see what happens.

My question is not toward the MMR/3-racing FAN, But to Radioshack cooling fan that I stated above since it requires lots voltage will this drain your batteries down if you used them?

The amp draw that MMR fan is less than the 3-racing that I used I don't have any problem with it so you should be fine.

One question does the air needs to blow directly to the motor or away from the motor to dissepate heat?

So the FAN needs to draw heat out the motor?

Where can you get muchmore cooling FAN here in U.S and I'll try one?

cheers

I've seen at speedtech they have MMR FAN that measures 30mm X 30mm but it's out of stock, But this will probably fit to 3-racing heatsink co'z the
3-racing fun is measured pretty muh the same. That is if your Fan is measured like this.

That fan is 12v, so it'll never get the voltage it needs from your battery pack.

The fans will not slow down your car.

I would stick with blowing air at and over the motor. The endbell specifically, since blowing air at the outside of the can will do next to nothing. Blowing air to the endbell will help keep cooler air around it which dissipate heat.

I've read somewhere in these threads , that the cool air will be pulled into the motor at the endbell and hot air exhausted thru the vents in the can. SO, if this is true, blowing a fan at the can will actually make the motor hotter since it is impeding the natural flow of air.

nowaday you guy can used a small lipo cell to power your 1 or 4 fan in one short no matter how many fan you put it also wont suck so you battery power. you fan will be more high speed becasue lipo have higher voltage
