I've been running TPFC on dozens - if not hundreds - of ThinkPads over the last several years, never had an issue. It works better on some than the others, and one would be well-advised to test different versions.
Since the program can be modified by user, warnings simply must be there since one never knows who might start playing with it, and what damage can be incurred in the process... TPFC was never meant to deal with downshifting the CPU, just with optimizing the fan operation. The most expensive PATA drive will run you less than $100, which is a starting point for a good tested T4x motherboard, not to mention labour and inconvenience of having to swap the board. To me personally, the choice is simple. As always, YMMV.

It also comes with dire warnings that it's experimental, may corrupt embedded controller etc. But mostly it doesn't seem to perform the function I'm looking for - downshift the CPU speed at a lower temp than the factory overtemp setting. Leaving the machine on leaves the HD on, plus... at 25c/ KWH even 30 watts x 750 hrs/month is about $50-ish a year. ----- Re - Regarding T4x temp control First and foremost, to avoid the GPU problem, always lift the machine with both hands. If possible, never and I mean NEVER let it go to sleep or shut it off, just turn the LCD off when not in use. You can also try ThinkPad Fan Control, a lot of users are quite happy with it. Hope this helps. Cheers, George in reply to- Regarding T4x temp control There is a set temp at which the system will cut CPU speed, and a slightly higher temp at which it shuts down. Mobilemeter reports these are 88.5 and 93 C, respectively. Is there a reasonable way to reset these? I'd like to lower the first temp to stay clear of the T4x GPU issue and keep the machine a bit further from accelerated aging.
