DIY coolers basically enables the user to place the fan at the appropriate (hot places/vents).... U2 does exactly that with the removable and adjustable fans, why not?
Anyway, you won't be able to reduce 10 degrees+, its not possible for a normal cooler pad

yes i know that u2 fans can be place at the hot places and vent..
but is is power by 5v usb..
while d.i.y cooler can be powered by 12v adapter and more power fan..
i really need the powerful fan because my room quite hot ...
my friends tell me that i shold buy table fan but i need portable cooler.
huhu
thanks for the help [PF] T.J...

For Acer's 4820TG what's the best cooler that suit her? Budget less than 150

Cooler Master U2 is good, Rm60-70

U2 compare with infinite?
but 1 more thing is, how about the sounds? cause I not sure whether how loud is 15dba-20dba..=.=

dont matter la if the cooler is silent or not..
the main thing is we want to cool the laptop..
hehe

What about an elevation on the laptop? Like from a battery, like the Dell 9 cells? I've heard it's the best way, but it's awkward to add a cooler to an elevated laptop.

Yup elevated laptop helps a few degrees I guess

Here's my cheapest solution. I get this from my friend 3 fan cheap laptop cooler, the fan is dead and he wanted to throw them away so I take then, remove the fan and rotate them as such



The 4 legs acts as a lifter to the laptop so it will give sufficient air to the bottom of the laptop to allow it to breathe. I use it as such (because its on my bed I pointing it upward from behind)



Pictures quality aren't so good but you get the picture. This are my best solution that don't use any money at all. Easy, free and noiseless and no vibration whatsoever. My laptop is cool to begin with so I quite happy with it

Creative and environmentally friendly bro
Anyway, neck won't pain ar if use like that?

Why? It facing me. Its the same idea as sunken hinge, it makes the screen faces you, in this it makes the laptop faces you. Try it.

Okay okay, I think I get what you mean already
But usually I won't last long sitting on the bed like that, legs will become numb really easily

I played a lot of games on my acer 5750G and always recorded heat upto 70-75C.Is this normal temps? Will it affect the components?

There is 5750G thread, you should asked there. But those temperature is fine

sifus, recommend some cooler for asus a52j? zalman nc1000 able to fit the asus n53sn ar?

NC2000 is better for 15'',
