Note that the temperature values are not in Celsius as I already mentioned, but in duty cycles of a PWM pin input. So after checking a dump from 8740w, the pre-defined look-up table looks like this: And this is something I don't want to be responsible for. For low fan speeds, the minimum fan speed should be kept at 1000 RPM, while the maximum fan speed should be 2000 RPM.I can think about adding some simple option to fix an issue, but giving the users too much control over the Temperature/Fan LUT (Look-Up Table) would be a bit complicated to implement and if not properly configured could cause damage. This will result in throttling and system crashes and may damage the CPU. What If CPU Fan Speed Is Decreased Too Much?ĭecreasing the fan speed to an extremely low RPM rate will cause serious overheating since there would not be enough air to dissipate the heat generated by the CPU. The recommended safe minimum fan speed is 3000 RPM, while the maximum safe fan speed is 4000 RPM. Increasing the CPU fan speed beyond safe limits will result in loud noises, overheating and, eventually, damage to the CPU. What If CPU Fan Speed Is Increased Too Much?

For instance, a gaming laptop should be kept at 100% RPM at 70☌ and 50% RPM between 50☌ and 55☌. Furthermore, this may be different from what purpose the computer serves. For instance, a large fan running between 1000 RPM and 2000 RPM may maintain the same system temperature as a small fan running between 3000 RPM and 4000 RPM. However, this may vary for each fan size.

This is what should be the ideal CPU fan speed. Mac Fan Control can control the fan controllers by allowing users to set fan speeds of their choice.Ī good fan speed should be between the ranges of 3000 RPM and 4000 RPM. Fan controllers are usually coupled with thermal sensors that adjust the fan speed when a temperature change is sensed. Mac Fan Control is owned by CrystalIDEA and works by monitoring and controlling the speed of fan controllers. The Pro version costs $14.95 for a macOS license and $24.95 for both macOS and Windows. Mac Fan Control has a free version and a “Pro” version available. Using Mac Fan Control is safe when used properly. Mac Fan Control helps users overcome MacBook Pro overheating problems and noise issues caused by replacing Mac hard drives, which are a few strong sides to using this software. On the other hand, in custom mode, the software controls the fans either by setting fan speeds or using sensor-based control. When set to auto mode, the program switches to monitoring while system fans work in the default mode. Mac Fan Control’s unique feature is called “fan preset,” which supports two modes: auto and custom.
