I took it apart by removing the Antec sticker on the fan that held a rubber plug in place to retain the grease.
The fan spindle was held in place with a Teflon retaining washer. I removed it by using a x-acto knife to spread the washer wide enough to clear the spindle. This washer had a break in it where I was able to insert the blade.
After it was removed there was a o-ring at either side of the spindle to retain the grease further.I removed the fan blades and spindle from the body.
As I inspected the fan I saw long har wrapped around the spindle and a little dust. I removed the hair removed the dust with compressed air and then a soft rag. To re-esemble it I used a little synthetic grease I had, I probably should have used dielectric grease, but; since I was just tinkering and did not have any on hand. I went with the synthetic because I knew it was good for high rpm lubricant, and it is a fine grease compared to say wheel bearing grease. I put everything back as it was snapped the retaining washer on the spindle. I needed to secure the rubber plug, but; the Antec stickers adhesive was not up to the task anymore. I used the Antec sticker as pattern grabed a vinyl sticker and cut out a new one to retain the plug.
