hi folks i need some to help me with this problem my lap fan
goes hot and heated up so fast although am using fan-cooler ?
what is causing it to be heated up that fast

Clean the fan labrynths and the filters.

check the processor fan. It might not working

You might need to apply some new Thermal Paste to the heatsink.

The only one to use is AS5 (Arctic Silver).

This should help your CPU run that little bit cooler. As Chris said make sure you clean out all your fans and heatsinks.

The dust is collecting which makes the fan ineffective. I wouldn't worry too much about killing the CPU and etc. Most CPU's now a days will automatically shut off after it gets to a certain temperature deemed too hot.
