Should CPU fan be set to PWM or auto?

A PWM fan works by pulsing voltage to the fans, more pulses faster the fan, less slower. Saying that again select the type that is correct for the fan, 3 pins are DC/Voltage and 4 pin are PWM controlled. In most circumstances you can just leave it on AUTO which automatically sets it to the correct mode.

What mode should my CPU fan be?

Standard = middle of the road, balanced. Silent = noise paramount, keep fan at its slowest speed, may throttle cpu down sooner to keep temp in check.

Do PC fans adjust automatically?

Champion. Yes, you can run your machine for a long time. As far as cooling goes, the automatic fan control systems constantly check temperatures and adjust fans accordingly.

How do I set my computer fans to auto?

Look for a System Configuration option, navigate to it (usually using the cursor keys), and then look for a setting related to your fan. On our test machine this was an option called ‘Fan Always On’ which was enabled. Most PCs will give you the option to set temperature thresholds when you want the fan to kick in.

Should I turn off smart fan mode?

I always use Smart fan control when available. You can usually tweak the profile if necessary (i.e set it to ramp up at different temperatures). This means that where the CPU temperature is low (like when idling), the fan can run at a low speed for less noise.

How do I manually regulate my fan speed?

Use the arrow keys on your keyboard to scroll through the BIOS menu to the “Monitor,” “Status” or other similarly named submenu (this will also vary slightly by manufacturer). Select the “Fan Speed Control” option from the submenu to open the fan controls.

How does the fan speed increase in manual mode?

The Manual Duty Cycle parameter is used to control this. Fan speed increases by this percentage for each degree over the minimum temperature. This parameter is only visible when the Control Mode is set to Manual.

How does auto control work on a fan?

In Automatic (Auto) control mode, the fan speed will vary automatically based on thermal conditions and configuration. The Minimum Duty Cycle, Maximum Duty Cycle, Primary Temperature Input, and Secondary Temperature Input parameters are used to specify the configuration for this mode. In Manual control mode, the fan spins at a fixed speed.

How to turn on automatic mode in SpeedFan 4.51?

This manual is outdated. To activate automatic mode in SpeedFan 4.51 go to “Configure” –> “Fan Control” (new tab) –> “Add” –> type your name –> Double click on an entry –> select fan (CPU0 in my case) –> select CPU and all cores. If I select “MAX of speeds” fan speed jup up and down between 51% and 100% even if computer doing nothing.

What are the options for fan speed control?

Fixed: Allows the fan speed to be set at a fixed speed and never change. Options are from 20 to 100 percent in 10 percent increments. 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).
