Update on L-Wireless Controller & Wireless Fan Receivers

Update on L-Wireless Controller & Wireless Fan Receivers

We’ve made some important improvements to both the L-Wireless Controller and Wireless Fan Receivers — here’s what’s new 👇

🔹 L-Wireless Controller

The new L-Wireless Controller is now smaller and no longer supports internal motherboard RPM sync or USB 2.0 9-pin connections. RPM sync functionality is now managed directly by the Wireless Fan Receiver.
Instead, the controller connects to your motherboard’s rear USB Type-A port — providing a cleaner setup and ensuring optimal wireless performance.

In the previous version, users could connect the controller to an internal USB 2.0 header or use an external Type-A port for convenience. While connecting it externally may offer slightly better signal performance, using an internal connection does not necessarily cause issues under normal conditions. However, the Wireless Controller is not recommended to share a USB hub with other devices, which is often the case when connected to an internal USB 2.0 header.

By connecting the new controller directly to the rear USB Type-A port, it now operates on a dedicated USB channel, helping avoid potential interference and ensuring a more stable wireless connection.

Note: The new dongle mainly improves size and usability — functionality remains the same as the previous version. 

🔹 Wireless Fan Receivers

We’ve made key updates to enhance performance and stability:


• Removed automatic motherboard-sync timeout fallback — fans will no longer spin up unexpectedly when the signal is lost.
• Unbound wireless fans now default to 1000 RPM instead.
• Fixed excessive fluctuation in FG (tachometer) signal output, preventing erratic fan-speed readings during MB Sync mode.


You can identify the newest wireless fan receivers by checking the manufacturing date label — if there’s an “A” next to the date, it’s the updated version.
