[SOLVED] Strange liquid on case fans

[amulsingh01]

I opened my PC to clean it and found some green liquid present on 3 of my case fans (All three exhaust). It's not on anything else and I've included an image below. Could anyone have any guesses what it could be from? I don't have a liquid cooler and have never spilled anything into the PC.

This is probably bearing lubricant.

So nothing to be worried about? I can clean it and move on

Well the lubricant came from a fan. It's a leak. I would replace the fan.

Yep, that is bearing lubricant, most modern PC fans have liquid filled bearings to reduce noise, the seal can fail then while the fans are running the liquid tracks along the blades and colects on the fan surround, I see it a lot in the big server racks where I work

It's not going to damage your PC so you could clean it off but the fans will be running at reduced performance and it will continue to leak until they stop working
