I found a bug, at least in my particular case. I use 2 7950s. cgminer sorts them as as they are physically installed in the system, as does HWINFO, but cgwatcher sees gpu0 as gpu1 and gpu1 as gpu0. Because of this and as my lower card is much hotter than the upper one, it tries to lower the intensity of what it thinks is gpu0, thus slowing down the real first card and of course, this doesn't help with the temp (on rare occasions my bottom card's core touches 91 or so *C, only when mining LTC). Also, using --no-adl argument if it helps.

L.E. Got more info, putting it together now.

last 40 or so hours' log: http://pastebin.com/7JCNbsKe and latest screenshot: http://imageshack.us/photo/my-images/849/screenshotjfv.jpg/

For some reason, CGWatcher also stopped logging (for) the past 12 hours (notice 7AM compared to 7PM in tray), otherwise it was responsive to menus. I'm guessing this is why the restart computer when sick/dead didn't kick in either, as set.

Furthermore, while mining the GPUs in devices tab appear as "INACTIVE", even tho respective values are reported/updated accordingly (this I rechecked after system reboot). I haven't tried clicking ENABLE while cgminer's working tho. I don't understand why I'm getting SICK/DEAD lately, parameters haven't been tinkered with for a month, and it was running 24/7 without issues since. I think after 1.1.4 these problems started surfacing, but I don't know if it's related, just an observation.

Meh.
