Top 3 fan brands?

[Ocean Spray]

Top 3 fan brands in terms of pricing and quality.

Also, can you guys tell me the difference between a fan such as http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065

compared to

http://www.newegg.com/Product/Product.aspx?Item=N82E16835103055

I know the second one is clearly better but what really differentiates the pricing and is it really much of a huge difference? Also, how many fans do you think a gaming computer should have? I'll most likely run my computer 20/7 or just long periods of time with 8GB ram and an i5 2500k processor.

It will depend of the temperature from your cpu and gpu how many fans you'll need. You need at least 2 fans.
The fans you posted are cpu-coolers. If you are choosing between this 2, take the hyper 212 plus.

Top three brands are probably Scythe, Noiseblocker, and I guess Cooler Master

Not saying its the one you should or shouldn't get but the Hyper can have a fan on each side for push/pull to increase its already good performance.
As well as feedback, here's some comparisomes.

What case is it?

I use only Noctuas..

Not the cheapest, probably not the best but they are quiet enough for me and do the job!
