Looking for 140mm Fans

Hey! I'm looking to purchase two 140mm fans from Microcenter, so make sure any options you give me are Microcenter. First and foremost, I cannot have sleeve bearings. These are being horizontally mounted. I'd also prefer to not purchase any Corsair fans.

Here's what is confusing me: the different bearings. I know ball, double ball, rifle, and FDB. But then you have hydraulic, hydro dynamic, long life, and other weird bearings. Microcenter has a ton of Hydraulic options: http://www.microcenter.com/search/search_results.aspx?Ntk=all&sortby=match&N=4294966926+23+4294929697+4294929700+4294958544+4294929690&myStore=true

I'm not sure what to get, though. I'll pay probably up to $25 for each fan. Any assistance? Thanks!
 
Solution
If you must order from Micro Center, then probably the Aerocool Shark fans. The H.E.C. COUGAR Vortex Hydro Dynamic Bearing 140mm Silent Cooling Fan looks pretty good too.


I think I'm going to hold off on the fan or maybe look at other options like Amazon. I agree, the Aerocool were what I was looking at, but I constantly have a poor experience with fans that I want to make sure I get some nice ball bearing fans from Be Quiet or Noctua.
 


That's probably what I would do too. Buy once. Be happy.
