Thanks for getting back to me so quickly.
First, to be fair to Noctua:
I emailed them Dec 9. I immediately got an automated reply. And I now see that they sent me a full reply in under 24 hours. I just somehow missed it in my mailbox (I think I got a ton of mail that day and it must have gotten marked "read" without me noticing it).
Here was their reply:
First of all many thanks for choosing a Noctua product.
We are very sorry to hear that you are having issues with your NF-A9x14 fan.
Please send us a proof of purchase (screenshot, scanned invoice, etc.) for your CPU cooler as well as your full shipping address. We would like to send you a replacement fan as it is very likely that your fan is affected by a manufacturing defect.
I'm looking forward to hearing from you.
Noctua support team
I just sent them a copy of the invoice, so it looks like they'll be taking care of that.
(It was very, very hard to find the right place to contact them. And the one I found was a page in German and it kept staying in German even when I clicked English, so that was annoying.)
You're right, I have the other fan around here somewhere. But I have to remove the heatsink and redo the thermal paste too right? (It would be so nice if the other fan happened to fit on top of this heatsink.)
Just so I learn something more: Why would those 2 fans I pointed to not work? Is it because they're too big for the Antec case? (one of them goes on and on in the description about how it fits almost any case)
At least I have a temporary solution and
now a final solution too.
Another question entirely:
There's no problem adding another SSD drive to this system right? I have a Samsung SSD 500 GB on it now. I'm thinking about moving that on to my laptop and gettting a 1 TB SSD on this system. But for a while I'll probably leave both installed on my desktop. It looks like this ASROCK board as perhaps 6 ATA spots for drives. Right now 1 is taken up with my current drive and 1 for the front port. I seem to still have 1 black ATA 6G cable left too (or do new drives tend to come with their own cables anyway?).
The power supply to the new drive appears to be more of an issue, but I see one that piggy backs from the current drive, so that should work.
