Damn that's pretty good. And your battery life is good? What kind of profiles you got set?

Kinda funny. They both are merely accessing the power/cpu settings built into the linux kernel. I posted a long time ago either here or alldroid (too bad all that good info is gone) a link from IBM talking about all this, what the various governors do, advanced settings like power bias, threshhold...etc.
personally I'd go with setcpu. I don't use the widget, it's stupid to think you can see realtime cpu speed.... but that aside it's just a nice gui for configuring basically the same thing pete is starting to do, plus I like having profiles for various situations. I think the setcpu dev should change how they work though. let us add custom profiles as many as we want, with a number (for priority) a function (battery%, heat, time...etc) and a cpu speed governor setting.
The Cpu is actually rated for -30 to 105 C (2 to 221F) at least the last time I checked the tech manual, sgx(taz said it) and there was a post that was from an engineer from TI that basically confirmed it as well. But thats the extreme limits and def not what the surrounding chips as noted can tolerate. I think 60-65c (140 to 149F ish) was about as high as one should go and even then only for small time periods. (pretty close to what you said)
Just something to toss out there, the battery has a rated max of 60C at least my orginal one im still using says it on the sticker. Knowing this and the fact that my cpu can take much more than the battery can I just let setcpu use the battery temp as a failsafe at about 55 56c. seems to work ok. I've been noticing at least for my phone that with the newer kernels like bekits .084 series and the new 507.1 CM rom that I seem to run much cooler. Can't complain about that.
My profiles are:
Main: 1.2Ghz max, 550 min, ondemand, set at boot, advanced: 62500, 70, 0, 70
Charging: 550 max, min, ondemand
Sleep/Standby: 550 max, min, ondemand
Power <35%: 1000max, 550min, ondemand
Power <25%: 800max, 550 min, ondemand
Power <15%: 550max, 550min, ondemand
Failsafe: >47.8 (118F): 550max, 550min ondemand
Again, I don't know if I'm just getting inaccurate readings, but I'd imagine i'd feel some heat if i was. But I don't. Runs cool 65-105F always.
I've deleted the "overclocking" lines in the pete script and just have the "task manager" lines. BB is a great ROM, but for me at least, setCPU is a must.

Thats our cpu info I copied it from a thread on this site while ago and pasted i in notepad so thats whyit looks like that...im sure its still in the thread somewhere but everyone seems to post specs for the cpu that our cpu is closley related to. this was a heated discussion and this was the facts from our cpu there was also a link in that thread to this info i's sorry i didnt save the link or the thread. the info posted for the closley related cpu had 2 diferent sets of temps and there was to debate on which one was which then this info was poseted. it says 0-70c
Ive seen a few people say there getting results almost the same as the "never goes over 100F" post. Ive had 3 droids so far, the all ran in the 130 range when overclocked to 1100+. bad luck on my part or good luck on yours =) who knows.
as far as the question about adding a script that can lower the clock speed when a failsafe temp is met. no, its not doable. the script only runs ones on boot. once it runs its done. it just tells the phone, this is what the cpu should run at. its not activly running in the background to make changes on the fly when temps get high.
from what I can tell by all the posts on this, the over all agrement is there is no overall agrement lol. it depends on the phone, type of user and clock speed. for me, I just removed the cpu script and run setcpu. it what worked for me with v1 so why change what wasnt broken
