Might be my ignorance of MSI Afterburner but it only seems to show me “GPU temperature.” If I run CPUID’s free HWMonitor app or TechPowerUp’s free GPU-Z app, those apps show in addition the GPU memory and the GPU “hotspot” temperatures. The worst is GPU memory, at least for the 3090 and it’s already been mentioned on the forum. In spite of reaching a memory temperature of 94 deg C (when the supposed thermal limit of the card is 93 deg C), my 3090 FE card fan was only running at about 1,100 rpm. I used MSI Afterburner to crank both fan speeds up to 2,300 rpm, which according to the MSI Afterburner curve is close to max fan speed (a review says max is 2,600 rpm). The GPU temperature fell to 53 deg C and the GPU memory to < 80 deg C. It’s a bit noisy but fits right in with the GA aircraft and helicopters I like to fly! So although in terms of sim performance it’s good to max out your GPU usage, if you have a plain vanilla FE 3090 as I do or something similar, you might want to carefully check your GPU memory and hotspot temperatures with one of the apps that I mention. My room temperature is around 28 deg C (83 deg F). The 3090 is sitting outside my computer all by itself on a riser stand so it should be getting the max possible ventilation.
