AMD Radeon RX 7900 XTX RDNA3 Reference Design Features Fan Intake Temp Sensors, ARGB LEDs


AMD Radeon RX 7900 XTX reference design graphics card features an innovative new real-time monitoring feature, the Fan Intake Temperature Sensors. The reference-design RX 7900 XTX cooler has the ability to report individual fan-speeds to software (which isn’t new, given that each fan will independently connect to the PCB); but what’s new is that each of the fans has a temperature sensor that can detect the temperature of the air as it’s being drawn in, before reaching the heatsink.

The temperature measurement of the fan intake sensors should give you a fair idea of what is the ambient temperature inside your case. At this point we don’t know if the feature is exclusive to the AMD reference design, or if the company has shared the know-how with its add-in board (AIB) partners to add to their custom-design products. This sensor should be accessible by AMD Software, the utilities included by AIB partners, and we will try to add ability to read from this sensor to TechPowerUp GPU-Z. The reference RX 7900 XTX cooler also features addressable RGB LEDs, first ever for a reference-design graphics card (they’ve had single-color lighting).
