Having trouble finding replacement fan for this case

[SmartSpot]

I have an Antec 900 case. It's been working great except the fan on the top now rattles. I took it to the store but they said they don't have any fans the right size or shape. The case has been discontinued, however I found this fan on Amazon Will this fit? Can I use this fan as a replacement?

How can a fan be the right size but still not work?

The one you've linked to is the correct replacement fan. Here are Antec's guides for replacing the fan:

Read the hardware specs for your case, since you need a 200mm fan.

Start off with aero cool fans for that one, I had these in the past with my old aero case.
As a few reviewers mentioned it will hold out for 3 to 5 years.

This is optional for the front and side of your cases.

Yes Higher RPM means better airflow with cooling and it does benefit the cpu heat sink fan.
