Antminer S19 S19k Pro S21 T21 Temperature IC Replacement Module – Gold Quality

Antminer Temperature IC Replacement Module | Immersion Gold Sensor Repair Module for S19 / S19 Pro / S19j Pro / S19XP / S19k Pro / S21 / T21 Hashboards

The Antminer Temperature IC Replacement Module is the drop-in sensor module for restoring failed temperature sensing chips on a broad slice of the modern Antminer lineup — S19, S19 Pro, S19j Pro, S19XP, S19k Pro, S21 and T21 hashboards. When a temperature sensor fails, the miner controller loses thermal feedback from the affected board and typically throttles the entire miner as a safety response. Replacing the sensor module restores accurate temperature reporting and clears the throttle.

Built with an immersion gold finish for enhanced conductivity and long-term reliability under sustained mining duty. Each module covers one sensor position per hashboard — straightforward repair with minimal downtime. Cost-effective alternative to full hashboard replacement when the only fault is the sensor IC.

When to Replace the Temperature IC Module

• Temperature sensor fault flagged in the miner dashboard — specific board reports missing or erratic temperature.
• Miner throttling despite normal hashboard temps — bad sensor reporting a false high reading triggers protective throttle.
• Post-repair restoration — sensor module damaged during hashboard rework, replace before reinstalling.
• Fleet refurbishment — proactive sensor module swap on aging hashboards before redeployment.
• Visible damage on the original module — burn marks, lifted pads, surge damage.

FAQ — Antminer Temperature IC Module

Q: How do I identify which sensor on which board is the failed one?
A: Check the miner dashboard — temperature readings should be roughly consistent across boards under load. A board reporting NaN, 0°C, an obviously low value, or an extreme high value is the candidate for sensor replacement. Confirm by running the board on a test fixture if you have one.

Q: Will the module work on the older S17 / S19 Hydro / S21 Hydro hashboards?
A: The listed compatibility covers the standard S19 / S21 air-cooled generations. Earlier S17 and the Hydro variants may use a different sensor module — verify against the part marking on your original module before substituting.

Q: Does the immersion gold finish matter for reliability?
A: Yes — immersion gold (ENIG) finish resists oxidation and gives better long-term contact reliability than standard tin-plated finishes, important for sensor signals where high contact resistance would shift readings.
