Hello everyone.
I am probably on the right place (because i am the owner of Aspire
5745G with a i7-720QM). I have a question about
cpu fan speed on my
5745G, namely
can it be controled via BIOS ?
I spend last few days observing CPU temps (CORE TEMP) and relevant cpu fans speeds. I think that the CPU fan rotation speed is not adequate.
Example:
on start up :
cpu temp = 58 C
fan-speed =very slow (level 1)
after 2-3 minute (there is no user activity on notebook) :
cpu temp = 48 C
fan-speed =very slow (level 1)
there is light activity on laptop :
cpu temp = 54 C
fan-speed = a slightly faster than at the start (level 2)
there is moderate to heavy activity on laptop :
cpu temp = 70 C
fan-speed = a bit faster than in case of light activity (level 3)
there is extra heavy activity on laptop, all cores are on 100 % :
cpu temp = 81 C
fan-speed = very fast (level 4)
Then i started to use RW Everything and i was able to detect a bit who controls cpu fan speed (it is 50x0E, can be seen on a pic). Initial value of 50x0E is consistent with the value of 50x05 and it is value of
02. If i put the value of
13 into 50x0E, the cpu fan spins up much faster, i can say on the level 3. But, if the value of 50x05 is changing (because of cpu temp change!), the value of 50x0E is also changing (it drops) and cpu fan spins down, slower and slower, to the level 1. So, it must be manually set back to value of 13.
Now, the most important question for me is:
can you modify the BIOS so i can control the CPU fan speed from BIOS ?

Thank you in advance.
