| Platform | Gigabyte 965-S3 / IT8718F sensor | OS | All xp32/xp64/vista/win7 | ||
| Product Version | 4.42 | ||||
| Summary | 0001768: Behavior of IT8718F. (Pwm1 + 3) = Speed1 | ||||
| Description | My Hardware: This motherboard Gigabyte 965-S3 (rev C2, F14 bios) using the IT8718F sensor, and motherboard has fan headers in FAN1 & FAN2 only (FAN3,FAN4,FAN5 are unused in this revision). It has speed sensors detected in SpeedFan of PWM1 PWM2 PWM3. Bug: This is something that was driving me crazy. I could hear my computer making a different sound when I adjust PWM3, but there was no fan header or 3rd fan! It turned out PWM1 and PWM3 both affect My Fan1 speed. So I figured PWM3 is unused, but actually: Fan1 speed ~= (Pwm1 + 3 combined) So, PWM1 and PWM3 both affecting Speed01. Like a Fan speed multiplier. So Is it how the hardware was made or is a software bug? | ||||
| Steps To Reproduce | 1. install motherboard with i8718f on gigabyte 965p-ds3 2. adjust pwm1 and pwm3 speed 3. ????????????? 4. Fan1 RPM adjust from both! | ||||

I encountered the same behaviour on a Gigabyte P67A-UD3; I tend to think it's by design. My guess is that it's intended to give you a 'finer' adjustment of the processor fan speed. Details here: http://www.bugtrack.almico.com/view.php?id=1741 |
