This dose depend on the position of everything of course, fan infront of the motor in the direction of travel needs to be blowing, fan behind the motor needs to be sucking.

I'd like to see pics on how that was accomplished, but (like many such temp lowering propositions) it seems be a rather drastic change that seems rather unobtainable. 10 degrees just seems like a huge variation.
But, being as most rc company's fans are designed to blow on items, it makes sense they'd know what they're doing (maybe not
).
Yet it also seems that a lot of people use fans as a fix to address overheating, despite them being more of a bandage, as I was always taught to get your temps to an acceptable level before adding a fan.
