Depends what you mean by "in contact", the aluminium motor can will be in direct contact with the motor mount, which in *some* cars will be directly screwed to the chassis, so there will be some cooling effect (DEX410 for example).
A DEX210 has no direct, metal to metal, contact between the motor and chassis (unless the motor is resting on the chassis, because its (slightly) oversized) mine has a ~1mm gap between chassis and can. So cooling the chassis will have little effect. AFAIK, most transverse motored buggies are like this, the motor plate is mounted to the gearbox (plastic) and the gearbox is bolted to the chassis. A stand mounted fan also won't do much to the ESC as there is a nice piece of insulating tape between it and the chassis!
Another benefit of the loose fan is that not only will it cool your motor, it'll also cool your ESC and (in the case of my DEX410) the centre props (which get quite hot) and the slipper..........
I have actually looked at slotting a spare chassis on my 410 to help with motor cooling in hot weather, this would make the stand mounted fan work quite nicely. But i haven't got around to it yet.
