Default here's mine

This is the other version of the 3Racing Fan. I connected mine to the "BAT" of the reciever which also gives 7.2 volts.

People here are reversing the waythe fan moves by re-soldering the (+) and (-) wires, vice versa in the fan so it blows in air, as opposed to sucking air.

No need to reverse polarity when soldering.... just turn the fan upside down...

Anyone know where these are sold in the US? I found their HK site but was wondering if a US on line shop had them?

If you had black or Purple I'd say sure. Blue wouldn't look too good with the purple on the Mi2EC Thanks anyways.

Hey guys which one is better the one on the side or the one heatsink directly above it? I would think the heatsink and fan that are standing up would be better becuase heat travels UP wouldnt it have a better effect?

Should the fan be directed at the air vents of the can, or just any other area will do? Should the fan be blowing onto or away from the can?

From my understanding...the fan should be BLOWING into the comm, rather than onto the can.

Cheers

Default Here a pic of mine.

Is there suppose to be a gap between the motor and the arch of the heatsink. Just wondering. Thought maybe so the air could move through it.

Side-version vs. top-version - neither is better, it just depends which fits your car better. Top version is better for most people.

Air gap - If there is an air gap it isn't deliberate, it is just an effect of clipping the motor onto motors that are of fractionally different diameter. The heat is transferred by conduction (contact of the motor to the heatsink), and the air is then drawn through the slots in the heatsink. This is a heatsink with a cooling fan, not just a fan support.
