Anyone know why my Mac is running hotter than usual??

I just had it professionally cleaned of dust since its an older model a couple months ago. It isn't running any unusual programs but the fan is kicking into hyperdrive after like 5 minutes now and the bottom is hot to the touch. The hot air is coming up through my keyboard too. I am very concerned since this is super unusual for it.

Sometimes Macs over-heat. It has aluminum body for a reason. They dissipate heat better than plastic.

Go to your activity monitor and see what threads (threads are not applications, but a part if it ) is consuming more memory/CPU. Sometimes add-ins to Firefox, or some other background job takes a lot of resources. Kill those threads that you don’t need.

If it still doesn’t work, you may need to consider upgrading the iOS to the laterest version.
