Learn About Laptop Coolers

What is it?

It is a part that takes the heat off the laptop CPU & GPU. CPUs & GPUs operate at a certain range of temperatures. If it is too cold (-40 Celsius) or if it is too hot (+150 Celsius), CPUs & GPUs can't work, and they might get permanently damaged from such extreme temperatures. Normally, CPUs & GPUs operate in room temperatures (23 Celsius), however, when active and underload CPUs & GPUs generate a lot of heat, which can take them very quickly to very high temperatures. As a result, CPU & GPUs need something to take off the heat from them to keep them running at full speed sustainably. This is where the laptop cooler comes in. It is designed to take the heat off the CPU & GPU to make it run at maximum performance for the longest period of time.

How does it work?

Laptop coolers work by doing the following (over simplified) steps:

1. Take heat off the CPU & GPU
2. Dissipate heat into the air

Look for

• Performance

  Check how the laptop cooler performs at your normal workload

• Sustained Performance

  Check if the laptop cooler can sustain performance at an acceptable level

  Laptop coolers can lose performance if they were under load for longer periods of time.

• Noise Levels

  Make sure the laptop cooler has acceptable noise levels

  This is directly correlated with power consumption and cooling headroom. You need less power consumption and more cooling headroom to reduce noise levels.

Avoid

• Type Comparisons

  Avoid comparing laptop coolers based on type, instead focus on performance

  Vapor chamber laptop coolers can perform better than air based ones, but it is not always the case.
