I bought a "broke" Toshiba Satellite A105-S2101 laptop off ebay that would freeze on the bios loading screen, bought it and found out it was just a bad DVD drive, replaced it and all is well. Except it overheats and shuts off after like 15 min.

It has a Intel Celeron M 420, its a Socket M, the fan works of course, the heat sink is clean, the thermal paste was pretty dry so I ordered some, it'll be here in a few days, but if it still acts up after new paste, would one of the other socket M CPU's better as far as staying cooler, doesn't necessarily have to be faster?

According to cpu-world these are the available Socket M cpus,

  • Intel Core Solo
  • Intel Core Duo
  • Intel Celeron M 400 series
  • Intel Celeron M 500 series
  • Intel Pentium Dual-Core Mobile
  • Intel Core 2 Duo Mobile

I read on a yahoo answers post that Celeron M's are known for getting hot, and even a Core Duo would run cooler?

But the info on the Xpress 200M chipset says it supports "Intel® Pentium® M, Intel® Celeron®, Celeron® M and Intel® Pentium® 4 processors"

THEN a guy at this link says he bought a Core Duo CPU and put it in a similar laptop with the same chipset and it worked, so I dont know what to think? Notebook Review Post

Anyone have more knowlege on this?

I would like to get a Core Duo T2300E if it would work, and if it would run cooler, they have them less than $10 all day long on ebay. I just going to resell the laptop after I get the overheating problem fixed

Make sure you have a BIOS version which supports the new CPU. –  Hennes Oct 2 '12 at 16:03
    
Your choices on a laptop are limited to the point the aftermarket on cpu coolers does not exist. Your limited to laptop coolers with fans that blow air into the case ( depending on air vent placement ) or cooling pads. –  Ramhound Oct 2 '12 at 16:43
