How do intercoolers work when you're on the dyno..?

I know the air hits the intercoolers when you're moving and that cools it..But when you're on a dyno you're standing still..Theres no air coming at the car...and unlike the radiator there is no fan to cool it when standing still..

So in reality you would make more hp off the dyno in the street with the air hitting it ..right??
Also has anyone hooked up fans the intercooler..?

 

In reality they dyno is supposed to have a fan to simulaye air flow from what I have heard and seen in some articles but in real life I havent seen anyone actually use that fan ?

Yeah I know about the fan,,But some people dont have those nice fans that look like turbos that sit low right in front of the intercooler..Most people use those huge fans and point them at the motor instead of the intercooler.
