Cooling Fan

To exchange the bluetooth device, I went to the shop again today.
At first, hesitated jugak nak exchange dengan ape.

• Laptop skin (RM23)
• Cooling Fan (RM21)
• Laptop carrying case (RM21)

I was confused which one I need the most and eventually I exchanged with the cooling fan.
Is it necessary to use it? Or is it just a waste?

Ade a bit problem with my lappy but maybe gonna "hospitalized" my lappy tomorrow. Hopefully its not gonna take that long. Really need it once sem starts.
By fetched Yu Full and George to remove his stuffs again. And then Yu Full said that I've been cheated pulak.
I can cheaper one. Hurm ntah la. Redha je la.
