That shouldn't be the problem with the Turion though. A ML-40 does not generate more heat than a ML-30 by design. Just check the AMD link I posted earlier. They have all the same TDP.
The cooling system of the 4402 is designed to handle the TDP of the ML series, and therefore should be able to handle all ML and MT series CPUs.
The Mobile Athlons are a whole different league, these chips have a TDP of 60 Watts and more, and I never would try to put them in a notebook that was designed for a Turion.
Of course the BIOS support could be a problem, not sure if the 4402's bios is recognizing the faster / newer chips. Might need a BIOS update.
Again, I am just stating facts that are on the official product website, and theoretically it should work. It might not though.
Of course Acer will tell you that you can't do that, because they want to sell you a better notebook.
