Hi everyone,
I’m looking for some advice about my Sapphire RX 6900 XT Nitro+ SE temperatures and hotspot.
I’ve attached HWiNFO screenshots with all the sensor data.
Current undervolt:
• 2409 MHz @ 1090 mV
(Stock is usually around 2509 MHz @ 1175 mV)
Stress test: 3DMark Steel Nomad
In games, the hotspot still reaches similar temperatures, around 107°C.
I already replaced the thermal paste with Arctic MX-6, but it didn’t really help.
Temperatures were slightly lower for the first few weeks, then increased by only a few degrees and stabilized at the current levels, pads are still stock.
I’m considering using Thermal Grizzly PhaseSheet PTM.
In your opinion, would it be better to:
• Replace only the paste
• Replace pads and paste
• Or further tweak the undervolt
Any feedback would be appreciated. Thanks!
