I have a pavilion-g6 laptop ....... an the other day I bought a cheap cooling pad for it................
just wanted to know that the laptop has some vents at the bottom and a side vent...............while gaming hot air blows out of the side vents..................so what does the other bottom vents do?.................do they suck in air???.....if they do so then shouldn't my cooling pad help those vents to suck n air .......rather than blow out air from them.................because I feel it doing so........................and if it does so.......am I disrupting the air flow by creating an opposite one???????...............is there any way of determining the air flow direction of a cooling pad or a vent????

Hi
Normally cooling pads blow cool air onto the bottom of the laptop.
The vent in the bottom is almost certainly air intake and the cooling pad needs to blow air to assist this.
To test if its an intake have laptop working hard then separate a tissue into a single ply then tear a thin strip off it and hold to vent,if it sticks to vent then it is intake if it blows away from vent then it is exhaust.
