Query: A Balancing Act...

I have a Dell Inspiron 1720 and the Notepal is not deep enough,front to back, for my PC to sit in it properly. It is also heavy. Especially when combined with my PC. Picture me trying to sit and hold my PC, this cooler, and do a balancing act to hold it all together without dropping the whole thing. It will keep your computer running cool. But the reason I bought it was to keep my leg from burning up while holding my laptop in my lap. The 2 fans are relatively quiet and are supposed to be good for 30,000 hours. It comes with a USB cable and needs no other power source. If you only use your laptop on a desktop then this might be good enough but lap use is precarious at best.
