Meh, I`d go for something that will lift the laptop about 2" off the desk b4 thinking of laptop coolers.
Flat on the desk, many HP AMDx2 based lappys get to 50million degrees just sitting there! Put em on something akin to stilts and they only reach 25million!
See if u can comfortably and strategically raise it off the flat surface and see how that goes for a bit.
Are there any that bring in air from the rear/sides then blow it upwards as bringing in air from the base doesnt sound a good idea to me..especially if its on your lap
They all seem to shave about 10 degrees off no matter what price
Kemp does the cooler operate well enough on your lap (as in does it hinder airflow going to the fans? Where does the air go once blown at the bottom of the unit?)
