I'm having trouble with my PC water loop—it's not circulating at all. I tried to set it up based on a diagram I found online, but something's clearly off. Does anyone have any ideas or troubleshooting tips?

Are you using a custom loop or an AIO system? If it’s a custom loop, make sure everything is properly connected and that there are no leaks. Sometimes a little repositioning helps too!
If you need to show us what you’re dealing with, you can upload your setup photos to Imgur and share the link here. It helps a ton to see what’s going on!

First off, is your pump plugged in properly? Sometimes it's the simplest things! If the pump is on and you can hear it running, then that’s a good sign. Next, check for any kinks in the tubing that might be blocking the flow.
It’s definitely running, so maybe consider checking the reservoir for air bubbles. They can cause a blockage.

Yeah, it’s a custom loop. I just can’t figure out why it isn’t working.
