So the laptop doesn't overheat.
Because its too old LOL
Temperature gauge not moved and the fan's always are working
It is the Lenovo Fan Speed Control Driver. Current file name ID1FSC01WW6.exe is for Windows 7 (64-bit) I have an SL300 with a fan always working on Windows 8 x64 Pro. This driver installed just fine and is reported as working under device management. But I see no performance improvement or manual controls over my laptop's fan speed.
The fan inside the laptop creates airflow inside the computer case. They help to regulate the heat of the laptop's CPU and GPU.
You need to place the USB fan cooler beneath your laptop and connect it to one of the ports for it to cool your laptop.
It is upto your choice to have a fan in addition to built in fan.
Your processor might overheat and you will get a damaged processor (not working properly or not working at all) inside of your laptop on your hands.
Dell's latest BIOS for your laptop features an improvement which keeps your laptop quieter, longer. They do this by raising the temperature at which your laptop must get to before the fan turns on. It may seem like your fan never turns on, but the truth of the matter is your BIOS is telling your fan not to turn on because it simply is not hot enough yet. Rest assured, when your laptop gets too hot the fan will kick on.
Which fan is not working? Engine fan or HVAC fan?
It depends on which type of laptop fan you are asking about. There is a an internal fan inside your laptop which is very small anywhere from two to one-inch in diameter. There are external fans you can buy to place under the laptop to dissipate heat radiating from the shell. These are much larger with more throughput of air.
take that fan out and then clean it. ( then put it back in)
