Well compared to my old cooler that I use on my Toshiba there is almost no difference but the price. The Cooler Master was twice the money of the old one. As I said,its quite cool under the laptop but thats not the point. And I don't think I should replace the TIM, the laptop is 3 weeks old but I'm going to change the thermal paste after the warranty is off.
Long story short, the U2 cooler (and all other there is) can't "cool" your laptop alot, 5 degrees is probably the optimal limit of it. Also I didn't know that the U2 actually blows air into the machine and thats not what I wanted....

Dear Kostadin... but that's the whole point of it... the laptop fan sucks air into the machine and
the cooling pad must blow in the very same direction (into the laptop) to help increase the airflow.
Otherwise a sucking cooling pad would fight the build-in fan with the result of no cooling airflow at all.

I'm not entirely sure about that because as I said my old cooler is sucking the air and it does the same job(the cooling is almost the same). Also the main reason why I did not want the cooler to blow the air into the machine is dust. I think that this will make my laptop dustier no matter how often I clean the table beneath it.

Kostadinbal I agree with you about the dust. The U2 cooler doesn't help alot but I have to clean my laptop more often now because of it. But sucking the air out would be helpful only if you had the "sucking vents"(hah funny^^) on the side grill where the air blows out. Otherwise the laws of physics would be on Zehnsteins' side It would nullify itself or perhaps even go the other way and it would mean that the default laptop fan would be totally useless.

I just remove the "user removable" fan cover which is held in place by 6 screws. Then I take an air compressor and spray some air in from about 40cm away. While doing that, I hold the fan in place so it doesn't overspin the fan and make it useless. I do it about every 3-5 weeks and I still can't believe how much dust my U2 fans get into my laptop. Oh and if you would like to clean it even more thoroughly, unscrew the 3 tiny screws that hold the fan in place. Take the fan out and clean the grill with an air compressor or just blow any dirt off. Then just replace the fan back to where it was(try not to lose the 3 screws from the fan as they are extremely small and they tend to get lost pretty fast), then just close the cover which is over the fan and tighten the screws(not too much though) and voila, that's it btw, I heard that vacuuming might really damage the pc, don't know why or how because I don't vacuum it(because I got and old loud strong vacuum hah).

A friend of mine who works as a maintenance specialist cleans them with a vacuum so thats why I do it like this. I'm a bit scared to open the laptop because I migh loose the warranty ( don't know if it is true but...) Do you think there is a way to decrease the dust flow into the machine? I clean the glass table beneath my laptop twice a day but it is in a busy room so there is always dust flying around.
Thanks for the info Zit.
