IS-F08 Thermal Control Board — User Manual

Step-by-step installation, jumper settings, alert reference and troubleshooting for your IS-F08 thermal control board.

Installation
  1. Connect the IS-F08 to a standard Molex 4-pin power connector from the power supply.
  2. Mount the board using the 4 supplied screws. If installed outside a 19" rack (e.g. a standard PC chassis), insert the supplied plastic sheet between the board and the chassis to avoid short circuit.
  3. Connect your 3-pin clock-type fans to the fan headers. The detection IC will automatically identify the number and position of connected fans at power-on.
  4. Attach the flat-head temperature sensors (S1, S2) to the components you wish to monitor using tape. Each sensor wire is 72cm long.
  5. Set the temperature alarm threshold for each sensor using the jumpers (see table below).
Jumper Temperature Settings
ThresholdRecommended UseSensor
50°CSensitive components — early warningS1 and/or S2 (independent)
60°CStandard equipment — general useS1 and/or S2 (independent)
70°CHigh-performance components — max toleranceS1 and/or S2 (independent)

S1 and S2 can be set to different thresholds. Incorrect jumper setup may trigger false alarms.

Alerts & Troubleshooting
Alerts & Normal Operation
  • Fan LED On (Steady): All connected fans are functioning normally
  • Fan LED Flashing + Buzzer: One or more fans have failed — replace, same connector position
  • S1/S2 LED Flashing + Buzzer: Sensor detected overheating — address cooling immediately
  • RESET Button: Silences the buzzer temporarily — fault must be resolved to stop LED flashing
Troubleshooting
  • Fan failure alarm: Press RESET to stop the buzzer. If the LED keeps flashing, replace the faulty fan and reinstall it in the exact same position — changing positions will trigger a new alarm.
  • Temperature alarm: Press RESET to stop the buzzer. If the S1 or S2 LED keeps flashing, improve cooling for that component or review the jumper threshold setting.
  • System not functioning: Check for a power shortage, a malfunctioning fan, or a faulty temperature sensor.
Important: Always power off the system before moving the control board or unplugging the 4-pin Molex connector. Hot-unplugging can damage the IC or the circuit board. Fans must be 3-pin clock type — other fan types are not supported. Never relocate a fan while the board is powered on.
