The third wire provides feedback on the actual RPM of the fan. Fans with 4 wires are controlled through pulse width modulation (PWM), in theory a more efficient way of controlling the fan speed. See Lm_sensors for generic details.įans with 2 or 3 wires may have voltage regulation: higher voltage (typically up to 12 Volt) results in higher rotation per minute (RPM). AFAIK there is no way to do this via BIOS etc, since the GPU temp readings come from an expansion card, not something directly placed on the motherboard. Specific hardware may have specific needs with respect to kernel configuration. Fans that allow their speed to be controlled.A motherboard capable of regulating fan speeds.A BIOS that allows users to control the fan speed.

Higher temperatures cause more wear on the electronics, resulting in a shorter lifespan.Ĭontrolling fan speed is not supported on all computers.

What if the program controlling the fans fails? The computer could overheat and parts could be destroyed. Stream Processors 6144 Compute Units 96 CU (with RT+AI Accelerators) Infinity Cache 96MB Ray Accelerators 96 Memory Size/Bus 24GB/384 bit GDDR6 Memory Clock 20 Gbps Effective Displays Maximum 4 Displays Resolution HDMI: 7680×4320 DisplayPort 2.1: 7680×4320 Interface PCI-Express 4.

There are two risks when manually controlling fan speeds: It is generally considered more safe to have the BIOS or dedicated hardware control the fans.
