Hey all. I don’t know if it’s a faux pas to put help requests here, but I’ve got an issue with a basically brand new AIO cooler in the PC I just put together, and since I’d rather die than ask this on reddit, I figured I’d take a shot and ask my favorite people before throwing up my hands and sending it in for warranty service (again).

So long story short, it was briefly functional when I got it, then crapped out, so I sent it in to be “fixed”. I got it back the other day, and reinstalled it and booted up the system today. Pump came on after a minute or so, CPU was running at a good temp, and I was all ready to install my OS. But, I dicked up the BIOS settings and had to reset CMOS to fix it. After that, the pump and the radiator fans wouldn’t come on and weren’t detected by the motherboard (I should note that this is exactly what happened the first time). Tried it on every fan header on the board, nothing. No amount of fiddling with the fan settings in BIOS could get it working.

Would anybody who’s inclined to help my silly ass have any advice, or should I just insist that the clowns who sold it to me just replace it this time?

Edit: Forgot to note, the pump appears to be functioning, but none of the three fans are spinning
