I've searched the bowels of the internet but can't seem to find an answer to this problem. I'm getting some fan noise from either one or both of the fans on the top of my PC-P50 lian li case. I'm attempting to oil the bearings, but after peeling back the sticker, much to my dismay, I discovered that the usually-right-there black piece of rubber which leads to the bearing is actually completely covered by plastic, which extends out to all four corners of the fan, as seen here . I can't figure out how to get to the bearing. Although there is a little indentation / plastic circle directly over the bearing that looks like it may be able to be taken out, I don't actually think it can be.. any suggestions? Do I have to completely take the fan off the case (which involves completely removing my CPU from my MB, and possibly the MB itself?
