If you can successfully OC the CPU but keep the bus speed the same, it shouldn't make a difference to the GPU. Whether or not a too high fps is a root cause is as-of-now just a theory proposed by Igor. Running stress tests and benchmarks can help you determine the optimal settings for your GPU. I've written an extensive GPU overclocking/undervolting guide as there's a lack of proper guides. This is not a gpu undervolt but I do undervolt my cpu on my laptop.

Undervolting can make a healthy difference, especially on AMD gpus. Unfortunately undervolting on laptops is sometimes just not possible. Good performance, sits at around 65c and doesn't draw ridiculous power (310w). All owners of an AMD Radeon graphics card should have access to Radeon Wattman, located within the Radeon Control Panel. My settings are currently stable at: GPU: 2700 / 2800MHz. If you want to save power and gain performance you need to cap the clocks lower than stock, but higher than they normally run, then undervolt. 9v and my temp gone from ~75c to ~68c (I have an 1080ti). For me undervolting a GPU it’s a must, I’m currently using a 6900XT XFX 319 MERC BLACK EDITION with 2 saved custom profiles but one proved to be more stable than the other in all games and I’m getting better temps, high or higher fps and low power consumption in games like forza horizon 5, rdr2, metro exodus enhanced edition at high … Good find! Never had a GPU with bad coil whine but it's nice to know it can possibly be eliminated with undervolting. If you would like your GPU to stay at a low frequency, use a kernel manager with an auto-apply feature.

Step 2: Drag the whole voltage curve down to the core clock you want to run your card at. There is a "proper" way to flatten the curve too - limit the clocks with Nvidia's command line utility.
