Hi there, after about 2 years of following this forum without registering, i found that i should do it by contributing something
I made a quick test with this new firmware and the old one.
The test was made by running glxgears and watching the temperature with iStat.
I ran the test for about 10 minutes with each and these are the results:
"old" firmware: temperature reached 77º on CPU and 80º on GPU, fans didn't rev up more than 2000rpm
new firmware: same temperature and same speed.
So not a big deal here. So i though about another thing. running 5 instances of glxgears, made the CPU reach about 95% usage in both cores.
the fans only start kicking when temperature reached 95º which was pretty high IMHO. GPU temperature stayed in about 80º and not much more. the highest i've seen was 84º but it was during the fan's speeding up.
max fan speed: 6000rpm
I can be wrong but, it seems it's more the work cpu load that makes the fans rev, because it was only after i started more processes that fans went up, i might be wrong and this might not have any sense, but it's been a while since i got my MBP running without smc Fan control, and i still think that this laptop runs pretty hot.
:after 30 minutes:
fans: 6009rpm
temps: CPU 83º / GPU 81º
cpu usage: around 90% total
when i opened the cpu usage window of iStat, i made the CPU running at 100% on both cores!
fans: 6013rpm (6k rpm must be max)
temps: cpu 95º / GPU 86º
As far as i can remember and can conclude from this update, it didn't change much, fans rev in way late and it seems that are "cpu usage related" (they seem to rev in faster if there is a higher cpu load)
After this test, idle 2004rpm, temp 56º.
I hope to have been useful to someone
EDIT: after a few more minutes of testing i can conclude that fans only start rev'ing up after CPU reaches 90º. i did another test with smc fan control with fans at 4000rpm default and it only started speeding up after cpu went 90º. cpu usage doesn't have any influence after this. it must have been some coincidence
EDIT2: oh and i forgot, i think the fan speeding is still a "slow" process. it's much faster to set smc fan control to XXXXrpm's than to wait for auto. i did it and smc set fans at 5500rpm faster than waiting for the long speeding up.
