I just put together a new PC with an AIO cooler, and everything powers on perfectly. The RGB lights on the cooler are working, but the fans themselves aren't spinning at all. I know that sometimes fans only come on when they hit a certain temperature, but I want to make sure there's nothing wrong. The BIOS shows the fans running at about 1000 RPM, but I can't see them moving. Does anyone have ideas on what could be causing this? Thanks!

You mentioned that the fans are connected to the AIO header instead of the CPU_FAN. That could be the issue! In most cases, you want to connect the fans directly to a header that allows for constant operation, like CPU_FAN. You can also try unplugging and replugging the connections to ensure they're secure. Checking the manual for your AIO could be helpful too, even if it claims to be an 'easy install.' Sometimes clues are buried in the documentation!
Typically, AIO cooler fans should spin at least a little to help cool your CPU. If they aren't moving at all, it might be a connection issue. Make sure they're properly plugged into the CPU_FAN header on your motherboard. Some AIOs have their own dedicated headers, so double-check where yours is connected. If you have the option, go into BIOS and play around with the fan settings to see if you can get them to respond. That could help identify if there’s a deeper issue with the cooler.
