I have a Li-Po battery charger that comes with its own cooling fan which, like most of the cooling fans, blows hot air out of the charger to cool the charger down.
I have a spare fan and I was wondering whether it should blow ambient air towards the charger or draw the hot air away from it?
It will be an external fan outside the casing of the charger. Charger itself is roughly the size of a normal Wi-Fi Adapter and the auxiliary fan has ben taken from a computer casing.
I know it does not really make much of a difference but was just curious as to which setup will perform better in order to dissipate the heat generated a little better.
If I had 2 extra fans would it be better if one was blowing air towards the charger and other was drawing away or both should be doing the same thing?
