notebook cooler is just a marketting crap ....
the laptop/notebook works fine even without the notebook cooler or whatever it's called ...
in fact, the notebook cooler does not benefit the laptop/notebook at all
if you want some elvelation for better typing it's best you get a children's table, their height is good ...
believe me, no matter how fancy is the notebook cooler is, whether they are made from steel, aluminium or even gold ..... the back of our laptop is PLASTIC .. and the heat transfer rate is insane! you can burn the plastic from 1 end to another and you cannot even feel the heat ...
if you really want to make your laptop cooler, send your laptop to the technician and replace the cooling fan with a higher power, change the thermal paste .. only by tweaking internally, that things can improve ...
if you want to cool through the plastic, that's a waste of time
so, is it true? some say it works some don't. i think the guy replying don't know what is physics.
the cooler i heard the most is zalman, cm and table fan, lol.
