In a screen before these settings list a dependant variable under PECI Mode called Offset to TCC Activation Temp that is currently -68. Smart Fan Start Offset (-) Default 44 (Range 10 to 127)įan 1 Slope PWM Value/1Unit I Default 5 (Range 1 to 15)įan 1 Full Speed Offset (-) Default 23 (Dependant variable) Smart Fan Start PWM Value Default 28 (Range 0 to127)
I have searched all over the net for the descriptions of the Smart Fan settings without success.Ĭan you please describe (in simple terms) what each of these controls does and what direction change does what: Drivers & Downloads You could download / install latest Dell Power Manager Service from your Drivers & Downloads page and then use the application to see if it will help with the heating problems. (With the fan at full speed, the temp never reaches above 46) I want a happy medium. It is used to resolve fan noise, overheating, and performance- related issues of the system. Even with Prime95 running both cores at 100% bringing the cpu temp to 62 degrees doesnt change the fan speed at all. When Smart Fan is enabled with the default settings, the fan runs at ~300 rpm regardless of the load. When Smart Fan is disabled speedfan registers the fan at 2200 rpm (full speed and a little loud).
The mobo has a feature called Smart Fan to adjust the CPU fan speed as necessary, however I do not understand the settings. In an effort to reduce CPU fan noise in my ECS G31T-M Motherboard (AMI bios v2.59), socket 775 e8400 Intel Core 2 Duo (Not OC), I replaced my very loud Thermaltake with a much quieter Scythe Shuirken SCSK-1000 that supports PWM (Power Width Modulation) adjustable fan speed control.
