upgrade celeron M to Pentium M for acer aspire 3620???

Thread Starter 
I have an acer laptop aspire 3620 with a celeron M processor. The CPU runs hot and the fan keeps running.

I wonder if it is possible to replace the celeron M with a pentium M processor?

You should have no problems putting a P-M in there. Though you will most likely need to get a 400fsb Dothan for it to work. I believe all the Celeron-M's work at 400fsb and the chipsets do not support the 533fsb Dothans.

EDIT: After a quick glance at the 3620's specs and looking up the Intel® 910GML chipset....it looks like you ARE stuck with a 400fsb CPU. The chipset specs can be found here.

Hm...I was looking to do the same thing, but have already bought an Intel 730 (1.6mhz 533FSB).

Are you sure the chipset doesn't work like RAM? Like how if your computer only supports 400mhz DDR2, but you put in 533mhz DDR2, it'll just run at 400mhz?

I'm pretty sure CPU's don't work like RAM. Even if they did, it would be kinda stupid to put a 533mhz P-M in a motherboard supporting only 400mhz CPU's. First of all, if you bought a 2Ghz P-M, it would run at 1.5ghz. You can get a 1.6-1.8Ghz 400fsb P-M for considerably less and it would be faster.

However, the older 400fsb Dothan's can be pinmodded to run at 533fsb because they run cool and are easily overclockable.

If you put faster ram in your computer (as long as its of the same type) it just gets downclocked.
The same will happen to the cpu, instead of running at 533fsb it will run with 400 fsb (as long as the mobo only supports 400 fsb, which i didn't check), this will lead to an 1.6ghz(533) P-M running at 1.2Ghz with 400 fsb - not really a nice solution - for sure undervoltageable like hell, but also not really what you want if you at least sometimes need computingpower.
