I gave these a try. I can't tell you if they are helping much or not, but since I was building a new system, I thought I'd give the Older Noctua 140mm fans a bit of help.



- Soft, quality silicone - The numbered notches are a nice touch and ensure uniform mounting - Flush mounting



Fit and installation was nice and easy looks great at the corners

-it's the only one -I didn't realize how much is going on with the fans mounts etc and SSD bay which is nice for case mods. -nice heavy gauge metal.

Were these necessary? Not sure. But they are cheap and any noise reduction is probably worth it. They fit in place and work fine on most noctua case fans.

I bought this screws in 2/8/2016 to use on my new 6 TB Western Digital Blue hard drive in my HP desktop computer. It fit just fine and match! Great quality! No problems with it! I'm happy with it! I would buy again when I almost running out of screws.



They're slot covers, what more could you possibly expect? Painted black is a major plus The design is the one I need for my case (more on that)


Price was reasonable, Perfect fit and finish, A good backup cover in case the glass one.



Stops dust. Has magnetic edges in case you can't bolt it on. I just use the magnets on the metal screens which cover my fans.
