Virtualization enabled every laptop to act as a Super Computer. Very efficient but what about overheat problem due to less efficient cooling system of the laptop. Low-cost cooling pads can work for 5-6 Degrees only. More than that need costly ones.
If you have purifier like Mi Air purifier you can use it as an excellent external cooling system for your laptop.
How to use Mi Air Purifier as an external cooling system to reduce 20 C temperature?
My Dell 7490 holding Vmware, Virtualbox with 32 GB RAM and cheap cooling pad unable to reduce as expected. So on weekend, I tried using Air Purifier as a cooling fan for my laptop.

So now result of using Air purifier as external cooling system

Above result achieved by keeping mode 3 of purifier which is noisy. If you keep Auto mode, you can reduce 15-20 degree C without any noise.
In this way, we can use Air purifier as an external cooling system for laptops which are overloaded with Virtualization tools.
The result is good but I am not aware of side effects on the laptop board with this air blow. Please leave your comment.
