How do you lower the CPU temperature of a laptop?

By dennis60439 ·
Have a Toshiba Satellite M305 laptop running Vista. According to utility software, the CPU is consistently running at 80 C.

Intel Mobile Core 2 Duo T5800 @ 2.00GHz 82 ??C
Merom 65nm Technology

No expert, but that seems exceedingly hot. Have cleaned the fan from outside, but wonder if I need to take it apart to attempt to clean the inside, or if this is "normal." Any suggestions would be appreciated.

I had similar problem my celeron started heating to 80 and 105 Celcius - afraid that the machine was already cooked I did something some say is risky I put a home vacuum machine hose over the all the air ducts about a minute at a time 3 or 4 times - machine completely off and battery removed. will you believe me now machine runs 40 to 50 C no issues even 2 days over weekend non stop.

Well I personally do not sell a NB

Without a Cooling Pad and I do not provide warranty work if the user doesn't use the Cool Pad.

NB's by their basic design get HOT nothing you can do to prevent that from happening so you need to take steps to prevent them getting overly hot.

The Cool Pads perform 2 functions they first provide lots of air and prevent the Air Intakes getting blocked and

As they have their own Fans in them they suck the air through faster than the NB can suck it in so they tend to take the bigger bits of air borne gunk away from the air intakes of the NB and prevent the CPU Heat Sink getting clogged.

I personally only use the Antec ones but you can use what you like.

Space below

In a pinch, if you don't have a cooling pad handy, often it will make a noticeable difference if you can just put something underneath the laptop to give it a little space between the bottom of the laptop and the surface on which it's sitting. Even just a couple of pencils under the corners can improve air flow enough to keep it from overheating.

Yes there is a way.

In fact what that guy did with his home vacuum machine is kind of what he had to do. It's just that it should have been done with a can of compressed air. Mostly what makes a processor to cook is the dirt that gets into the laptop, making the fan not working well. It should be done a little cautiously though because you don't want the fan to spin while you are doing that. Therefore get anything thin to delicately stop the fan and then apply the compressed air. You don't need to be afraid of doing it since its just compressed air but if your fan spins too fast it can be damaged. Also, apply a new thermal paste to the processor(a little advanced). Also you can underclock your processor IF and only IF you know what you are doing. I recommend the CPU temp to be 50C at maximum for a long lasting laptop.
