Is there a way to change my GPU to white without painting it?

Vinyl wrapping seems to be a popular method! You could also look into sublimation printing or cerakote for a more permanent solution. Just know that taking apart your GPU could be tricky.

It's a tough one—some say heating it up enough will make it glow white, but I wouldn't rely on that! Vinyl wrap or aftermarket parts seem to be the way to go.

If all else fails, you might have to sell your current GPU and buy a white one. But why not have some fun and try wrapping or using decals first?

Honestly, at this point, there aren’t many options that don't involve some kind of paint. You might be able to find white stickers or decals, but they're not going to give you that clean look you're after.

You could consider aftermarket GPU shrouds or wraps. Some users have had success with vinyl wraps that can withstand high temperatures. Just make sure it's rated for around 100°C so it won't peel off easily later on.
