CPU fans at 100% on S5500BC in "other" chassis

Jump to solution

Hi,

I recently bought a S5500BC on ebay and its doing its job well. But the fans are allways at 100% and i would prefer a little bit more silence. I have updated my firmware (incl. BIOS) and nothing changed. I found a post about fan speeds in non-intel chassis ( ) but if i look in my BC_BMC.sdr i cannot find 100% aka 64h settings. Does anyone knows what i need to change in my config?

//=========================================================================//

// Chassis Fan Control Domain 1 with profile 6,7 for Minimum

// For Other Chassis (Medium ramp)

// Fan Control Domain Number # 1 (PWM0: Processor1&2 Fan)

//====================================================================//

_SDR_TYPE C0

_SDR_TAG 'OTHER_MR'

_REC_LEN 001F

// Sensor Record Header

00BD // Record ID

51 // SDR Version

C0 // Record Type

1A // Record Length

// Record Body Bytes

570100 // Manufacturer ID

0C // Record Subtype Value (Fan Speed Control SDR Record, rev 2)

// Temperature Fan Control Record

01 // Record Version

01 // Fan Control Domain Number # 1 (PWM0: Processor1&2 Fan)

14 // Normal Control Value (14h = PWM 20%)

FF // Boost Control Value (FFh = use boost sub record)

01 // Ramp Step (1=1%)

02 // Scan Rate (2 Cycles)

C0 // Fan Profile Support = 11000000

// Stepwise Linear type Temperature Sensor Sub-record

20 // Sensor Owner ID

20 // Temperature Sensor Number -- (BB Amb)

64 // Temp Sensor failure control Value (64h = PWM 100%)

00 // Sleep Control Value

41 // [7:6]-Supported in S1 (1=yes); [5:3]-Reserved; [2:0]-Control Type (001b=Stepwise linear)

10 // Temperature Info [7]-Reserved; [6]-Domain Maximum=0; [5:3]-Negative Hysteresis=2; [2:0]-Positive Hysteresis=0

//------------------------------------------------------------------//

04 // Count of Temperature/Control Value Pairs (04h=4)

00 // Temperature 1 0c

33 // Control Value 1 (Percentage) (33h = PWM 51%)

14 // Temperature 2 20c

33 // Control Value 2 (Percentage) (33h = PWM 51%)

1E // Temperature 3 30c

33 // Control Value 3 (Percentage) (33h = PWM 51%)

3C // Temperature 4 60c

64 // Control Value 4 (Percentage) (64h = PWM 100%)

Also i am not sure which entries to alter and which not. Would appreciate any help,
