Lately I'm hearing a lot of noise from the home dock's fan. I tried unsuccessfully to blowing out stray dust with a can of air aimed into the back opening. Looks like a replacement fan will be needed. I was hoping to have one on hand before cracking it open. From what I can tell I'll need s 40x10mm, 12v fan. Somewhere I found (and then lost) a higher quality copy the last photo here:

Unfortunately that exact fan is no longer produced. Should this one do the trick, or is there a better choice?

That Noctua model is at least as good as any. I have a couple of the original fans here, but postage alone would be more than that one from Amazon.

Thanks for the details and confirmation that the Noctua fan will work.

Perfect replacement. Nice and quiet.
