i use a coolermaster x3, but i also spend 70+ hours week with the laptop on my lap for work, for me its made huge difference over the past 7 years, i used to get burns on my lap/lower abdomen, never owned a hard core gaming laptop either just vaio sz, z1, and then se 15. aside from the physical burns there would be times my laptops would overheat and shutdown because i had forgotten to turn on or plug in the cooler, but never had that happen with it on.
