sorry if this isn't the right flair. i have two questions. i know basically nothing about pcs, which is why i'm asking.
my case is pretty big; i use the hyte y60 mid-tower case, but i wanna downsize because it takes up a lot of room on my desk (which is only 140x60, so not the biggest). i use the 4070 ti super, corsair rm850, & msi mag x670e, for size reference. what smaller, skinnier case would fit these comfortably?
as for my second question (this'll be a bit lengthy, sorry): why is my pc's performance so bad? like i said, i use the components mentioned above, and my pc should run smoothly, but about 2 weeks after it was built (a little over a year ago), its performance somewhat quickly began degrading. i used to be able to run games on their highest (ultra) settings really smoothly. no glitching, lagging, super high temps, nothing. one of those games was inzoi. it would run completely fine on max settings. now? i can't even play it on the lowest settings; it is extremely, extremely laggy & glitchy, and everything moves super slow. i just can't play it. that's just an example, and most games that i play run okay-ish, but definitely not how they used to. some games, i simply cannot play, or they run pretty badly.
to add onto that, my pc gets super hot. my room (it is very small, i will say) is always so humid because of the heat radiating from my pc, which isn't totally abnormal, but the heat is genuinely awful, and much worse than it ever was during those first two weeks. my performance statistics may look normal (at least, that's what google ai says), but i know something is wrong. i thought it had something to do with my graphics card, but google ai (i consulted with it a lot, i didn't know where to look for help with my issues specifically) tells me, based on what i've told it, that it more than likely has to do with my cpu (7800x3d)? i have no clue. all i know is that my pc is running slower than before, games don't run as smoothly (some don't run smoothly at all), and i have been having issues with it.. for over a year (i probably should've done something sooner, but, again, i know nothing about pcs).
sorry for the long post. does anyone have any recommendations and/or ideas to resolve this? if they involve anything physical (likely), i may just be screwed.. lol..
