Signs your iMac 21.5-inch 4K A2116 needs this repair
- Fans very loud or constantly running
- Switches off without warning
- Hot to the touch
- Slows down after a while
- Rattling or grinding fan
- Overheating warnings
How we fix it
We clean dust out of the fans and heatsinks and replace dried-out thermal paste.
Worn or noisy fans are replaced, then we test temperatures under load.
How long it takes
Cleaning and fan repairs are usually done the same day or next working day.
Good to know: Keep vents clear of walls and curtains. Dust builds up faster in homes with pets.
