Solutions for overheating if your CPU heatsink is clogged

You can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides if your CPU heatsink is not clogged with dust and lint completely. As a precautionary measure, however, this may not work if your laptop already has a problem and the heatsink is completely clogged.

  1. For having access to the CPU fan and the heatsink open the laptop case. You can have access to the heatsink in some cases through the latch on the bottom of the laptop. While in some cases you have to open the laptop case all the way down.

  2. You have to remove the fan by carefully disconnecting the fan cables on the system board. We recommend you to replace the fan if it is making an unusual sound when it spins such as a grinding sound.

  3. With the help of compressed air, clean the fan and the heatsink.

  4. We would recommend you apply new grease for better heat conductivity by removing the old thermal grease from the CPU.

You can also use a vacuum cleaner to suck out the dust accumulated on the fan and the heat sink. We would also recommend you use a powerful air compressor instead of a vacuum cleaner. You can fix the problem at no charge from Toshiba Authorized Service Provider if your Toshiba Laptop is under warranty.
