bios update did indeed fix the problem. why is this shit so damn finicky? anyway, everything seems stable, started running layered stress tests and nothing blew up
I ran into one more problem with this build! so I got this 4070ti super, right. I knew the card worked fine, because I dumped it into my old build for a while because I hate building computers more than I hate anything else in life except maybe fascism, so I wanted to play around with the card before I fully committed to pain. anyway I build this computer and hammer out all the issues, including the expo shit. it takes forever, but I do it. so I’m like wow lets play some video games on this video game machine, as a treat. so I fire up a game, and immediately the GPU fans go ape shit, full fucking blast on frame 1. in my old computer this thing was very quiet, I was very impressed! now it is murdering me before anything even happens, even though the card is at like 40c. I investigate. msi afterburner isn’t reading the fans at all, they show 0%. fan control, however, will show me a fan, with another greyed out. I’ve never used the program before so I’m like whatever I guess it just does that. I start maxing that fan out in the program to see what it sounds like, and it doesn’t sound nearly as bad as what I’m getting in any game/furmark. I max every single detected fan in my entire system. it still doesn’t sound as bad as I get in game. a mystery fan! how intriguing! I’m like what the fuck, I built this computer one entire day ago, I paid for everything in it that spins, what fucking dimensional rift dropped an invisible fan in my case
I keep playing around with different fan settings in different programs. I learn that the fan detected by fan control is detected everywhere else, including in afterburner (afterburner will correctly report it’s percentage but not the RPM, because I guess afterburner sucks. this fan appears to behave normally, it ramps up over time as I run shit and the temps rise, I can hear it spinning up in the background layered behind the cacophony that is beginning to trigger me. I’m like maybe something happened, like a wire loosened somehow and now one of my GPU fans magically isn’t PMW anymore, so it’s just going from 0 to 100.
this was the last thing I wanted to check, because it involves maybe taking my computer apart. now, I can’t really see into this thing, the case is fucking monstrous and it’s on the floor in a weird somewhat inaccessible spot. I’m the kind of idiot that would rather investigate on the internet for 2 hours than pop that bitch open. but I half-ass it, I spin the computer around so I can kind of see in the case, because this PMW idea seems promising. can I see the fan wires? who knows, I guess I gotta check. and guess what I see! one of the stray fucking 8pin plugs hanging off one of the split cables powering this fucking card fell in some fucking angle good enough to jam it straight into the middle fan of my card. only I can’t figure out how to plug in the computer legos without doing something fucking stupid like this. my builds always look like a fucking disaster. anyway, I’m still not exactly sure how this caused my problem. I guess the card sensed that one of the fans was out of commission and compensated by cranking the shit out of the third? and fan control could only access one of them because of the sensor flipping out? and afterburner would register the fans as operating at 0rpm permanently because one of them, in fact, was? idk man, it works now, I’m fucking tired.
