**#**Caution you may destroy your device if not done correctly. It requires coretemp and applesmc kernel modules to be loaded. It only uses the temperatures from the processors as input. This enhanced version assumes any number of processors and fans (max. i have done this before 2years ago and it is hard really hard. mbpfan is a daemon that uses input from coretemp module and sets the fan speed using the applesmc module. If you have that much technical knowledge and you are comfortable with this much details then repasteing with a good thermal compound can solve this issue. Sometimes processor fan gets clogged and makes noise Sometimes the processor thermal compound gets dried up so it can’t transfer the heat efficiently it may cause this issue As your laptop was not sounding that before so Custom: Allows the fan speed to be customized based on processor temperature, minimum duty cycle, and duty cycle increment (see Other Fan Control Settings, below). Options are from 20 to 100 percent in 10 percent increments.

Watch the noise you are hearing is maybe due to overheating you can monitor the temperature of your cpu and if you think it is getting hot so your device fan gets rammed up like crazy. Option: Description: Fan Control Mode: Fixed: Allows the fan speed to be set at a fixed speed and never change.

You can kill that and see if issue resolves and give us feedback. If issue is that your processor getting hot that is why fan makes noise and you artificially slow down that fan it can lead to bad performance and thermal slowdown and may underperform your cpu.Īnd also monitor the applications if something is taking more than usual amount of resources like cpu.
