Laptop running hot or fan always loud? Here's why
Why laptops overheat and fans get loud, simple things to try, and when a cleaning or fan repair helps.
A hot laptop with a fan that never quiets down is usually a laptop that can't breathe. Heat slows it down and wears out parts over time.
Common causes:
- Dust packed in the fan and vents. This builds up over a few years, faster with pets.
- Using it on a bed, couch or lap, which blocks the air vents underneath.
- Old thermal paste between the chip and the cooler.
- A program running in the background using a lot of power.
Try this first:
- Use it on a hard, flat surface like a desk or table.
- On Windows, open Task Manager (Ctrl + Shift + Esc) and look for anything using a lot of CPU. On a Mac, use Activity Monitor.
- Restart it, and install pending updates.
When to bring it in:
- The fan grinds, clicks or rattles.
- The laptop shuts off by itself when it gets hot.
- The bottom is too hot to touch for long.
What we do: we open it up, clean the fan and heat sink, and check the fan itself. You get the price in writing first, and the check is free.
