Slower and Louder GPU Past Year

[MonkeyOfPeanuts]

About in the past year my GPU feels much slower and louder. When I play certain low demanding games like Roblox, Minecraft, SuchArt, or my editing software you can hear the fan constantly going “up and down” and in SuchArt the fan sounds like a jet engine. I believe it also now has coil whine, it makes a buzzing noise when I play sometimes. Turning on Vsync or capping the frame rate doesn’t help.
Any video editing software that I use such as Sony Vegas Pro 14 is significantly slower and nearly unusable (also within last year). You can hear the GPU (or at least I think is the GPU) ramping up whenever I do something such as moving a video clip and it is noticeably laggy to move it. The viewer in the corner lags a whole lot too.

Is this the fault of my GPU, memory or anything else. I don’t know much about computers, what should I do?

Thank you

gut reaction would be to take off the side cover and blow out all the air vents, fan blades and heat sinks of dust build-up with an air compressor.
canned air will work in a pinch but they cost a lot, run out in about 30 seconds and aren’t all that powerful.
get out your Dad’s air compressor, hold the fan blades still as you blow each one, and you’ll get it cleaner than fresh fallen snow.

I know a lot of people balk at using such high powered devices on dainty electronic gear, if you are one of those, fair enough, stick to the canned air process. all I can say is I have used home air compressors over 25 years on numerous PC’s (well over 500) without any ill-effects. but each to their own!

next you could look at the thermal paste on the GPU, after a year, it could have gone off, that is, lost it’s thermal load properties.
each card varies in construction so consult the manual on how yours can be maintained.
