I have an A45-S150 that suddenly started running VERY slowly because of 
overheating.  I did pretty much what you did but it didn't help.  The local 
Toshiba service center opened it up and said the motherboard wasn't 
communicating with the fan, and that a new board would be required (board + 
fan + labor = $500).

I bought a Thermaltake Mobile Fan II External USB Cooling Fan from Amazon 
for $16.50 and used Velcro and duct tape to stick it to the bottom of the 
case.  I use Motherboard Monitor to keep an eye on the CPU temp, and the fan 
does a fine job of cooling.  It's in the way a little bit and I can't use 
the computer on battery power, but the fan will get the job done until I can 
come up with the bucks for a new computer.
