Ventilation Fan - Intake or Exhaust

[johnslog000]

Just wondering if the left side vent on my laptop is an intake or an exhaust? It has what appears to be a filter on the other side of it inside the actual case, so I would assume that it is an intake, but when I put my hand up to it, I feel hot air coming out. I'm only wondering because of a cooler that I am looking at currently, which pulls air from the vent you place it on, I don't want to buy it and put it over the vent, only to find out that it's opposing the laptop's designed direction of air flow.

Fans are used to move air through the computer case. The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Case fans may be placed as intake fans, drawing cooler outside air in through the front or bottom of the chassis (where it may also be drawn over the internal hard drive racks), or exhaust fans, expelling warm air through the top or rear. 

Please refer to the below link to troubleshoot the issue.
