Fan monitoring board for I-Star D-Storm

The iStarUSA TC-ISF08 is an internal monitoring board designed for I-Star D-Storm cases. It tracks temperature at two points and watches up to 8 fans for failures. Power comes from a single Molex connector. Selectable jumpers set the thermal alarm threshold at 50, 60, or 70 °C.

Suited for critical-temperature systems

This board fits builders who need a single summarised fan-failure signal and visual LED alerts for a multi-fan chassis. It is not for users whose case lacks the specific D-Storm mounting points or connector layout. It is also not for setups that require per-fan RPM reporting rather than a combined fault line.

Dual-sensor thermal alarm with three thresholds

The decisive spec is the selectable alarm trigger at 50, 60, or 70 °C. Two included sensors let you monitor separate zones and the board sounds an alarm when either zone crosses the chosen limit. An onboard reset switch silences the alert until the hardware issue is fixed.

Questions about this item

Does the TC-ISF08 board itself contain any moving parts or consumable components that will need replacement later?

The board is a solid-state monitoring circuit with no moving parts; the only replaceable items are the two external temperature probes and up to eight fans that connect to it.

What is the first thermal limit the board will signal during sustained operation?

The lowest selectable alarm threshold is 50 °C, set by the onboard jumper, so that temperature is the first limit the board will report.

How much heat or noise does the TC-ISF08 add when it runs continuously?

The board draws power from a single Molex connector and has no fan of its own, so it adds negligible heat and no audible noise during all-day operation.
