Adequate aftermarket fan for my build

hello everyone

before i give you the background info, my main question will be as to any advice you can give me concerning aftermarket fans


so i chose parts for my first build. i had already placed the order, but couldn't help looking back over them online a few times in anticipation.

well, its looking like my cpu order doesn't include a stock fan. this was admittedly a newb oversight on my part, but having caught it before i started to assemble anything i'm not too worried. and i suppose it's just as well that i need to buy a fan, here's why:

the cpu i chose is -- AMD Phenom II x4 925 Deneb 2.8GHz

low clock speed for any of you enthusiasts out there i'm sure, and even as a beginner i'd like to see how much higher i can safely OC it, which i assume will be best done with some form of aftermarket cooling.

now, my case is a Rosewill Blackhawk, which is supposed to stay pretty cool, and i have a modular psu so the unobstructed airflow should help with that.

BUT -- i read a couple reviews of my mobo (ASRock Extreme3 970) which worry me a little bit if i want to OC.

1. "Chipset thermals are very high"
2. "Gets really hot for some reason... my north bridge is like on fire."

So now that anyone still reading gets a gold star, I'm wondering what sort of cpu fans I should look at that will work with all the above information. I'd like to find something pretty inexpensive that will still serve my mobo and oc needs. any advice on what factors to keep in mind?

thanks!
