Can I fix Vastarmor RX 9070 XT VRAM overheating in Marvel Rivals?
It's a joke that this 'super alloy' cooler actually lets the card overheat. The default fan profile on the Vastarmor RX 9070 XT is way too conservative. During heavy ability spam, VRAM temps hit 98℃, forcing the core clock to throttle down to 1200MHz. I tried dropping the resolution to cope, but the image looked like a pixelated mess and only dropped temps by 4℃—total placebo. I went into the Radeon software and set up a stepped fan curve, cranking it to 100% once it hits 70℃. GPU-Z showed the VRAM peak dropped from 99℃ to a range of 82 - 88℃, and the lagging stopped. The fans sounded like a jet engine at first, so I dialed back the 85℃+ speed to 80% for some sanity. Core temps are now 65 - 71℃. Exported the logs for my records. Thermal parameters are finally sorted.
