Which Air Flow Direction Should A Laptop Cooling Pad Have?
You basically have two choices;
- You can blow air upwards towards the base of your laptop.
- You can suck air downwards away from the base of your laptop.
The laws of physics dictate that hot air rises – so, in any particular area, you will normally find the coolest air nearest the floor. That’s probably why most laptops have their cold air intake on the underside, nearest whatever surface it’s resting on. It also stops the surface that the laptop is placed on (which might be your lap after all) getting hotter than it needs to.
In this scenario, a fan which blows air vertically upwards directly into the laptop’s cold air intake is best.
Some laptops, probably fewer than 10%, do expel hot air from the underside of the laptop. In this situation, you would be better to use a cooling pad which sucks air away from your laptop.
How To Check Your Laptop’s Cooling Configuration
There are a couple of simple tests that you can perform to check on the cooling arrangement of your laptop and make sure that you get the right type of cooling pad. Do these when your laptop has been running for a while and has had enough time to heat up.
- Locate the vents on your laptop.
- These will probably be located at the side, on the underside and possibly at the rear of the laptop near the hinge of the display.
- Place your hand near to the vent. If you can feel warm air, then it’s an exhaust.
- Alternatively, separate a piece of tissue so that you have a single-ply sheet. Hold it flat near a vent. If it adheres, then you have identified an intake.
Choosing The Right Laptop Cooling Pad

However, the simple test above will confirm what type you need.
If you’re really not sure, you could always pick a cooling pad which allows you to reverse the air flow. There are a few of these available – and the Cooler Master Comforter is a good example.
With this one, you can just pop out the central fan, turn it round so that it’s blowing in the direction you want, and then pop it right back in again.
