The Zalman F3 might be the best fan you'll find locally. It comes with silicone mounting pins and a voltage reducer that gets it down into the reasonably quiet range. The package should be under $10. Other than that you'll find more Antec and store-brand no-name fans (may be something good but you really will need to know your fans to be sure you're not getting junk as what's actually in the box can change whenever they get a better deal from a new supplier). The big box stores tend not to carry anything that has not been pre-marketed (familiar brands, etc.)... So you may find some Cooler Master too, but the more exotic brands you can forget.
