Help: Fan always running in Laptop

Sunday, June 21, 2009 by G3mpi3 | Discussion: Personal Computing

Hey everyone,


It seems my fan is always running at a low speed in my laptop. My computer never gets hot and I'm using only 0-5% CPU all the time. Is it normal for the fan to just constantly run.........even though my computer isn't hot or working hard? I think I remember my fan turning off and staying off until I use a certain amount of CPU. I'm using windows vista 64 bit and I have a intel centrino dual core processor. Any help or suggestions would be appreciated. Thanks.

On my old laptop (since deceased, it was about time) the fan was always running.

I've never used a computer where the fan wasn't always on..  Maybe I'm stuck back in the ages where if there is no fan then you're cpu is good as gone within seconds.

Check ur bios settings, should be a secion for fanspeed, etc.

Chech that you have latest BIOS for your model from your laptops manufacturers site. Download a Temp measuring program from the web to be sure the temps are within normal limits.

Laptops have the worst heat dissipation on God's green earth... Be worried when the fan _doesn't_ run constantly.

Fans are good my friend, the only time I would get worried is when it is not NOT on.

If it ran slower before to the point you could hardly hear it....I would recomend opening the back panal up and cleaning it out with compressed air. it may still be getting hot even though its not under much stress.

Never use compressed air from an air compressor unless you have a filtering system that removes moisture.

Also, when blowing out a fan make sure to keep it from spinning to avoid damage from spinning it past it's max rpm.

Never use compressed air with it powered, and make sure it's dry before plugging it back in.


Moisture isn't a problem, as long as you're not a tard.  The components will be obsolete long before they corrode, even with insignificant help from the occasional water vapor.
