For the Fans, try
Introduction to fan controlling for Macs
datcu-andrei-2.gitbook.io
Ive had a try at mbpfan ..first one on the list on my iMac 10,1
That link has wot must be the best instructions Ive read for a while. (The author assumes the reader knows very little, and writes accordingly.) So every thing worked according to the instruction..(oh except for something that was already sorted..so not really a fault.)
However the limitation the limitation is still there.. At the final stage one can access the bpfan.config file and set the fan speeds accordingly. But on my iMac,10 I get this:
----------------------------
"# see
https://ineed.coffee/3838/a-beginners-tutorial-for-mbpfan-under-ubuntu for the values
#
# mbpfan will load the max / min speed of from the files produced by the applesmc driver. If these files are not found it will set all fans to the default of min_speed = 2000 and max_speed = 6200
# by setting the values for the speeds in this config it will override whatever it finds in:
# /sys/devices/platform/applesmc.768/fan*_min
# /sys/devices/platform/applesmc.768/fan*_max
# or the defaults.
#
# multiple fans can be configured by using the config key of min_fan*_speed and max_fan*_speed
# the number used will correlate to the file number of the fan in the applesmc driver that are used to control the fan speed.
#
#min_fan1_speed = 2000 # put the *lowest* value of "cat /sys/devices/platform/applesmc.768/fan*_min"
#max_fan1_speed = 6200 # put the *highest* value of "cat /sys/devices/platform/applesmc.768/fan*_max"
# temperature units in celcius
low_temp = 53 # if temperature is below this, fans will run at minimum speed
high_temp = 56 # if temperature is above this, fan speed will gradually increase
max_temp = 76 # if temperature is above this, fans will run at maximum speed
polling_interval = 1 # default is 1 seconds"
(Note: Ive lowered those temps already by 10degrees.)
I do not get anything like this included:
[general]
min_fan_speed = 1299 # default is 2000
max_fan_speed = 6199 # default is 6200
..where one can change the fan speed setting..so not an option on my iMac 10,1. Have yet to try on my iMac 5,1 (but even less likely.)
By the way - that tutorial gives a good explanation about changing the settings:
I will try doing this again...in case I missed an important step.
There is also another option to try in your link,Tomcatrr - so big THANKS for that!!
