Hello everyone. I’m not fluent in English, so I’ll do my best. I recently bought a new PC about 6-7 months ago and noticed some water inside the 3/4 case fans. Several people on Reddit and other forums suggested that this kind of leakage is normal because they use more oil than recommended, which can cause problems if it builds up. I’m wondering whether I should take the PC to a repair shop or keep using it. I’ll share some photos—I see the PC looks dusty, possibly because the seller used some unnecessary stickers, and opening it might erase free diagnostics. The PC seller said they’d fix it, but the sales manager from the case manufacturer said she had never seen such an issue and that they don’t use oil in their products. I’m not an expert, but I’ve never seen a hydraulic bearing without oil, and I’m curious if that’s what’s happening. My case is from Croatian manufacturer Bit Force, model Voltron RGB-4, and I paid 75€ for it. From the pictures, each fan seems to have leaked a different amount of oil. Thank you in advance!

Here’s a clearer version:
The images show different fans in various positions—top case, front mid, front bottom, and back. Sorry for the unclear English.

In the initial image, you notice dark lines resembling oil. The first leak was minor, while the third and fourth images show darker, shiny marks. The second picture shows no visible marks since there was no leak. Under each fan sold, the label mentions hydraulic lubricant, suggesting it should be used for lubrication. I checked to confirm if this is indeed oil. I used a Q tip and collected some liquid from the leak in the latest photo—it appears to be an oil or lubricant type. Watching videos from GamerNexus with a Noctua technician confirmed they use lubrication products, and the video is about five months old. I believe you don’t need to replace new fans or fans with oil, as sealed lubricants are available online with many examples of leaks.
