Hi,
unfortunately have the same issue with 4530s.
I recently bought this device. It's really cool laptop, but this fan thing drives me crazy 
But thanks God I found this thread, I am not alone with this problem.
I tried your program and it works well for me too, but the fan is not off.
I noticed my laptop's temperature is 40 - 45 C without loading any hard soft and if I run something harder it raises up to 50 - 52 C . I think there is the problem with temp sensors or something like that. The normal range of temp for this type of CPU should be 30 - 35 C without loading.
So, I would like to ask you to write a new version of yours program when the fan starts buzzing from > 48 C and everything lesser than < 48 C the fan is OFF. If the temp more then > 48 C then it starts in a slow mode and so forth.
Thank you very much. I appreciate what you do.
Did some quick testing to see what the thresholds look like.
I can't get the fan to be at 128 state (the most silent) by itself. I even disabled one core and booted from a cold laptop. After a few seconds of booting windows, temp is 35C and the fan starts at the 82 state. I could not get it under 35C for a few minutes to see if it will drop to 128 or even 255...
Then started prime to see what are the exact temps where it starts to ramp up.
At 50C, we get the first increase in speed. From state 82 goes to state 74.
Enabled second core in bios, as i was wasting time waiting for more heat. At 60C, fan state 74 goes to fan state 65.
At 70C, fan state 64 jumps to fan state 59.
And finally, at 80C, fan state 59 goes to fan state 49.
I had to put TPFC in bios mode to get 128 state and block the vent with my hand for 30 seconds or so to get it to 80C. DSDT takes over once manual mode is selected and fan state 49 was set. Temp dropped fast as it was breathing well.
The drop points are like this:
-80C - fan state is 49
- Drop to 70C ---> fan state 59
- Drop to 60C ---> fan state 65
- Drop to 50C ---> fan state 74
- Drop to 40C ---> fan state 82
That is that.
Now if only there would be a way to just change the temps at which a fan state gets activated....
Trouble is i haven't seen the 128 state activated ever by the DSDT. I just have to put TPFC in bios mode and 128 state is locked in.
Where do we go from here?
