so overall ?
suck or blow ? which one is better ?
then i need to modify my cooler
but my fan is not that fast and i cant really detect , it is sucking or blowing

Does blow air in lappy help since inside soo pack with hardware.. Try suck the air out and see the diff

Cheers.

I got a question the laptop fan is blowing the air up to cool the CPU but the laptop cooler fan is sucking the air down The air that the blower can blow up is lesser ald compare with not using cooler.(How come the cpu still  can be colder?) .(or maybe the cooler is creating an air flow allow the cpu fan suck in  fresher air. ) And pls dun forget most of the laptops bottom are without hole 1 the cooling pad is only blow  the case but not blow into the laptop.Some kind of laptop's Ram slot's lid or HD lid maybe got vent hole so maybe we can try to suck the hot air from the ram's vent hole.   If the cooler's fan is toward the part which is without hole i prefer to blow if with hole maybe i'll try suck(suck the air from the vent hole).
