Hi guys:)I want to control my fans' speed relative to the higher temperature that a component has in the pc.Is it possible to do?Is it a good idea?

  • Can you provide your operating system, your motherboard model (or make + model of laptop if applicable), and any potential solutions you have already explored?

On an ASUS Maximus VIII HERO you will be able to set custom fan logic through the UEFI BIOS. When booting up, spam F9 a bunch before you get to your Windows loading screen, this should put you into the motherboard setup screen ("basic input/output system" or BIOS for short).

Poke around and look for fan controls. If you do not know what a setting does, it is wise not to change it without research into safe/compatible settings.

edit: your motherboard likely does this by default

Addtl info:

For much more granular, customizable, and robust control you can use an app like SpeedFan which allows for the ability to influence the speed of a fan given the temperature(s) of sensors other than those natively associated with the fan that is plugged into that header.

  • Yes but it does what I have asked?Does it set fans' speed relative to the higher temperature of the system?

  • Yes, it should have a graph that maps fan speed in RPM to CPU temperature. Most of them typically have a way to add points and create a curve along which the fan speed will change per temperature.

  • Something very similar to this: images.anandtech.com/doci/9729/…

  • No,i am thinking another thing.For example:I have 5 thermal sensors,I want that fan's speed will be controlled relative to the higher temperature that is detected from those thermal sensors

  • So you have 5 thermal sensors - are these external and plugged into the computer somehow?
