If you run a laptop without a fan, it may run (Not all laptops, though, only in certain models that have optimized CPU and GPU), but you will face the lag, freezing screen, immense slowness, and other outcomes.

Your laptop CPU and GPU get more than 100°C while it is working, And that heat increases rapidly if you do not use a proper cooling system. Till now, an exhaust fan is the most efficient way for laptop cooling. So, without it running a laptop means killing your laptop with your bare hand.

That is why you have to check if the laptop fan is working or not. A possible sign of a faulty fan is the slow-running laptop or getting unusual disturbance while using it.

So, a laptop can run without a fan but not for a long time. At least it is not an ideal suggestion to use a laptop without a fan.

  • If the laptop is connected to a charger, unplug that too.
  • Then, use that screwdriver to open the back part of the laptop.
  • Now, you will see the fan on the side of the laptop. Usually, you will see it beside the processor, but it depends on the laptop model. Eventually, you see it anywhere in the back.
  • Let’s look for the connectors of that fan.
  • There is a chance that it is not visible above.
  • So, you have to open the plastic cover or other parts that are covering the fan connector.
  • After unscrewing any part, make sure you remember everything and put the screw in a safe place for later use.
  • When you find the connector, carefully disconnect it.
  • Now, reassemble the parts that you have opened earlier.
  • Finally, put the battery back on and turn on the laptop.
