Firstly, I'm dumb. I removed a fan from my PSU to oil it, not expecting to be able to fix it. So I didn't pay close attention to the direction the fan was installed. I thought I installed it the way I removed it, but I'm not sure.
My PSU looks like this as it's from 2010 - https://i.ebayimg.com/images/g/ZhIAAOSw8gdd8BuY/s-l960.jpg
I thought on older PSUs, the fan blew outward (sucks air in through the PSU vents and blows it out the PSU fan - out the back of the computer case). But I installed it the opposite way - sucks air in from the outside and blows it out the vents in the PSU - blowing it out into the computer.
Looking at pictures of my model PSU (ATX0300D5WC Rev. B) on eBay, all the pictures show the fan oriented so it blows out, I installed it so it blows into the PSU.
Does anyone know which way it's supposed to blow air? It's possible my cousin may have worked on it around 2012 and installed it backwards. I have no idea. Should I install it the same way as in the pictures?
If my cousin installed it incorrectly when he worked on it, that could explain why the GPU keeps overheating as warm/hot air from the PSU is blowing downwards on it. I would think the fan blowing out (like in the pictures) would be better because the PSU would be sucking air up from the GPU and blowing it out the PSU and out the computer. The case fan is at the bottom of the computer, under the GPU. The PSU is at the top of the computer.
