ElphaPex DG1 DG1+ 4-in-1 Fan Speed Simulator for Crypto Miner Spoofer

ElphaPex DG1 / DG1+ 4-in-1 Fan Speed Simulator | Quad-Channel Spoofer for Water Cooling, Oil Immersion and Silencer Conversions

The ElphaPex DG1 / DG1+ 4-in-1 Fan Speed Simulator is the advanced version of the DG1 fan spoofer, featuring four interfaces that simulate four fans simultaneously. When converting an ElphaPex DG1 or DG1+ miner to water cooling, oil immersion or external silencer systems, the miner firmware expects tachometer signals from all four fan positions. Without these signals, the miner enters thermal protection and halts mining. This 4-in-1 spoofer provides all required fan signals from a single compact device.

The DG1 platform uses four fan positions. If your miner requires all four fan signals for full operation, the 4-in-1 version is required. If only two fan positions are monitored by firmware, the 2-in-1 spoofer is sufficient — check the miner's error logs after removing stock fans. The 4-in-1 spoofer ships with a built-in power voltage regulation circuit for stable operation across the DG1's fan-header voltage range, and connects plug-and-play to the existing fan headers without firmware modification.

When to Use the DG1 4-in-1 Fan Simulator

• Water cooling conversion on a DG1 / DG1+ — replaces fan tach signals after stock fans removed for hydro plates.
• Oil immersion deployment — same fan-signal spoof requirement, the DG1 firmware expects tach signal even though the miner is submerged.
• Silencer integration — external silencer system replaces stock fans, spoofer keeps the miner happy.
• Fan failure alerts on positions 3 and 4 — your firmware monitors all four positions, you need the 4-in-1 spoofer to clear the alarms.
• Multi-miner deployment — single SKU handles all DG1 / DG1+ units in the fleet.

FAQ — DG1 4-in-1 Fan Spoofer

Q: How do I choose between the 2-in-1 and 4-in-1 spoofer?
A: Check your DG1 firmware logs after removing stock fans. If you see fan failure alerts for positions 3 and 4, upgrade to the 4-in-1. If only positions 1 and 2 are monitored, the 2-in-1 is sufficient — and cheaper. When in doubt, the 4-in-1 covers all cases.

Q: Does the spoofer require firmware changes?
A: No — installation is plug-and-play. The spoofer presents valid tach signals to the miner controller; the firmware sees normal "fans running" and skips the thermal protection halt.

Q: Can I use this spoofer with a stock DG1 still running its fans?
A: The spoofer is designed for replacing fan signals when stock fans are removed. Running both creates conflicting tach signals on the same headers, which can confuse the controller.

Q: Bulk pricing for fleet conversions?
A: Yes — email contact@lys-sz.com with your DG1 / DG1+ count and we'll send case-quantity pricing.
