The fix involves either switching back to horizontal mounting or using a recessed aftermarket bracket like the Cooler Master Universal Mount B3 that moves the GPU 2–3 inches away from the glass. Beyond thermals, cheap PCIe riser cables also introduce signal integrity issues that can silently downgrade a GPU to lower PCIe bandwidth, causing stutters unrelated to heat. ## Full article daily.dev links to this article rather than hosting it.
