Low output and elevated hotspots observed.
I recently acquired this used ASUS TUF 3080 for a friend's upcoming project and began testing. The performance doesn't look quite right... The 4070 Super should only improve by about 9% compared to the 3080, yet it's clearly underperforming. Videos show other 3080s reaching around 135fps, which aligns with that estimate. The heat signatures and VRAM usage seem off, possibly pointing to thermal issues or hardware defects. The previous owner replaced the pads but reported no problems, though they mentioned it didn't resolve the issue. Other TUF users seem to agree on these observations. The latest temperature readings are for playing Genshin and PUBG. (Current / min / max / avg) Tomorrow I plan to check the frames per second in-game. It would be a mistake to swap them out again tonight. Any suggestions for fixing this? Options like underclocking or using Nvidia's automatic overclock? I also heard about replacing the pads with thinner versions since the standard ones are thick. Operating system: Windows 11 Pro 24H2 x64. System age: 3 months. OS installed 3 months ago. CPU: Ryzen 9 7900X. RAM: ADATA XPG Lancer Blade RGB, 32GB, DDR5, 6000MHz, CL30. Two video cards included: ASUS TUF Gaming Nvidia GeForce RTX 3080 OC Edition 10GB / Zotac 4070 Super Twin Edge OC. Motherboard: Gigabyte B650 EAGLE AX. Power supply: Corsair RM850x (2021). Laptop or desktop build.
Use Heaven Benchmark to mimic game rendering, observe the temperature changes, or simply launch a game to monitor performance and heat levels, especially with unlocked FPS settings.
The buyer was a friendly Ukrainian man who was raising his son and wife. He also mentioned he cautioned about the high temperatures and attempted to fix things by swapping out the thermal pads, though nothing seemed to change. He was selling this car because he upgraded to a 4070ti.
I'll check the pads and swap out the thermal paste if necessary. It's not the simplest step, but with a tutorial and attention to detail, you should be able to complete it. You'll need some specific items for the process.
Here are some photos. The cards aren't looking great from both my and my dad's perspectives. I plan to bring the card to a repair shop nearby tomorrow to find out what they recommend and the cost. I don't want to handle it myself—it's not my card, but mine is a friend's, so it's up to them.
That’s completely reasonable. When I disassembled the card, I wasn’t particularly calm, but as long as everything was placed correctly, it was functioning properly. You’ll notice during the repair if the technician examines the pads and paste—especially if they haven’t dried out or if there’s sufficient amount left.
