Hardware

I've recently started to unpack some of the boxes from my last move. In there I found an older Booksize PC, an ASUS Pundid-R350. It's not the nicest system I've ever had, the fan is incredibly noisy and it's constantly switching to full speed when the system is loaded. I guess I should swap the fan for something much quieter, but haven't had the time yet.

It took me some time to figure out the correct settings to have lm_sensors running on the device as there's been no template configuration to be found on google. To rectify this omission, I'm dumping mine on my blog:

# Asus Pundit-R350
chip "it8712-∗"

# Voltage monitors as advised in the It8705 data sheet

    label in0 "VCore 1"
    label in2 "+3.3V"
    label in3 "+5V"
    label in4 "+12V"

    # Seem not to be connected on the Pundit-R
    ignore in1
    ignore in5
    ignore in6
    ignore in7
    ignore in8
    ignore cpu0_vid

    compute in3 ((6.8/10)+1)∗@ ,  @/((6.8/10)+1)
    compute in4 ((30/10) +1)∗@  , @/((30/10) +1)

# Set some upper and lower limits

    set in0_min 1.4 ∗ 0.95
    set in0_max 1.4 ∗ 1.05
    set in2_min 3.3 ∗ 0.95
    set in2_max 3.3 ∗ 1.05
    set in3_min 5.0 ∗ 0.95
    set in3_max 5.0 ∗ 1.05
    set in4_min 12 ∗ 0.95
    set in4_max 12 ∗ 1.05

# Temperature
    label temp1       "CPU Temp"
    set temp1_type 3
    set   temp1_max   75
    set   temp1_min   15
    label temp2       "M/B Temp"
    set temp2_type 2
    set   temp2_max   55
    set   temp2_min   15
    ignore temp3

# Fans
   set fan1_div 2
   set fan1_min 2500
   ignore fan2
   ignore fan3

With this configuration written to /etc/sensors3.conf the freshly installed fedora 9 system correctly shows some sensible sensor readings:
