My old Celeron Toshiba laptop ("the celery") kept overheating - a persistent problem. Toshiba addressed the issue with a firmware update which helped some, but shutdowns persisted all summer. I finally sold it at Ebay, making the celery the next guy's problem.
For work I use an old Intel Macbook with a faster processor, yet there is no fan noise and it never overheats. It also cost a lot more. In my view, overheating = cheaply made.
I never use a laptop without a base that lifts it off the desk for air circulation.
