All cooling pads
do not throw air to the bottom of lappy pratyush.
You should seriously read the previous article which I told you to read. Tip: Buying a laptop cooler? Make sure you get the proper type! | dotTech
It clearly says that "If you happen to use the wrong type of cooler for your laptop, the cooler is actually hurting your laptop instead of helping it because obviously it is interfering with the cooling mechanism built into the notebook."
Or you can read this wikipedia link Laptop cooler - Wikipedia, the free encyclopedia
Read the second paragraph under active coolers.
P.S-Please don't get hyper on reading this.Try and understand what I am saying.I may be completely wrong(about U2) but I may be right too(in general).
EDIT:- I was wrong about U2,It blows cool air to the bottom.
Got confused due to the image posted on coolermaster.in.
The image showed that the hot air is sucked in,but it is actually showing the "Aluminum finish surface that allows fast and efficient heat dissipation"

Sorry for any inconvinience.
