What to do, what to do...
I would suggest for a budget on good quality fans, Yate Loons. I use these, and they are very good for the price.
The same guy that runs sidewindercomputers runs petra's as well.

Here is a test of the medium speed yate loon, the ones I've posted are high speed and what I use, Medium speed http://www.overclock.net/water-cooling/859483-round-6-fan-testing-working-thread.html#post11219376
Also a ton of other tests of a ton of other fans if you are interested.

EDIT:
Now, whether you decide what ever fan, they are most likely going to run some what loud.
I would suggest a lamptron fan controller as they are known for good quality.

If you could find a cheaper price on a lamptron fan controller, grab it. I doubt you or your lady will enjoy the sound of a black hawk next to you or her.
