CPU fan always ON!!

sj1187534 · 30-11-2007, 01:10 AM

I have a DELL inspiron 6000 with Vista ultimate installed on it. I recently noticed that while the PC is up, the cooling fan (or the CPU fan?) is ON about 80% of the time, even when the CPU is at 2 or 3%. Sometimes, I see this even when the CPU is 0%.

Does anyone have any idea on what may be going on here?

Thanks!

Well, generally, laptops don't have a whole lot of room for air movement. In order to keep the components from getting too warm, they tend to rely on fans a bit more. Additionally, unlike typical desktops, the size of fans available are smaller and need to spin at higher speeds to move enough air to keep the parts at a safe temperature. 0% CPU activity doesn't instantly translate into a slower cooling fan, as they're most likely temperature controlled.

Agreed..

That depends one many things: The environment weather, the surface where its laying and many other variables.

I always use my laptop on a hard surface so that it has enough space for the airflow. and the cooling vent is not under the laptop like some laptops do. I have seen my wife's laptop (Sony Vaio) and I rarely hear any fan soung although she uses her laptop more! Mine is a DELL.
