    During the warmer months my lappy gets hot and i need to cool it down. currently when the lappy is on my lap its on a board with holes for the air vents which are not covered. i have tried a cooling pad (not a cheapie from china) something that raises the lappy a bit, some other lappy fan and the usb flexible fan. the flexible fans work well but the motors burn out within 3/4 weeks. any ideas how i can keep my lappy cool?

    Many laptops have a modifiable internal fan speed - check your manual to see if this is the case, and how to activate if so..... Sometimes it's fn + key combination, sometimes it's in the bios settings.....

    I have found the heatsink can become clogged in laptops so if you are brave taking it apart and cleaning out the fluff can make a big difference.

    Very true - but you need to be careful with the conductive grease...... Best to google for a written explanation.....

    I put a Hoover suction tube over the air outlet from the fan. Gave it a blast at 3000rpm for a few seconds and all the dust was gone. It was a lot cooler and quieter after that.

    As others have said, get yourself a can of compressed air for the vents in the side also if you quite tech savvy whip the back plate off and where the main processer is it uses a conductive cooling paste. This hardens after time and you can purchase new stuff and just smear it over, remebering to clear the old stuff off.

    Quote: get yourself a can of compressed air for the vents

    I wopuld be careful when using a can of compressed air: if used close up, compressed air causes rapid cooling and briefly cause condensation which in theory could hit the dust and form a gloop that is harder to shift. If you use the compressed air from futher away, it probably won't clear the vents as you would wish. I would use the hoover option.

    Must try the hoover option - mine has started overheating and powering off when performing really intensive tasks (mainly when rendering previews in Lighroom), I found a quick solution which was to go in to the advanced power settings and to switch the max cpu down to 97%.

    How do you know it needs cooled down?

    A couple of months ago my Toshiba laptop started showing a window telling me there was an overheating problem. Have you seen something similar, or have you just decided it's too hot?

    In my case the cooling fan had stopped spinning. I looked at the vent to see if it was clogged with fluff. No fluff. I hadn't anything fine enough to poke through the vent, so I resorted to straightening out a paper-clip. Poked this through the vent and gave the fan a little push. I felt the tiniest click imaginable and the fan spun freely. Been working perfectly ever since. Smile

    take it apart from give it a good clean, chances are the heatsink and fan on the cpu are clogged with fluff etc. Also, make sure this intake and exhaust fans are clean too
