Getting a new CPU cooler (and other related items) to OC, and I don't know where to start

[PirateGaming]

Hello, and thank you for taking the time to visit my post!

I soon plan to get a new CPU cooler and a few fans and dust filters for my case. I have a HAF 912 for my case, and an i5 2500k as my CPU. Since i plan to OC, I saw it fit to get a new air cooler and new fans to take advantage of my cases capabilities, speaking of case capabilities, mine didnt come with any dust filters, so you guys know of any decent fans with built in filters, or filters i can add independent to the fane, that'd be great!

My budget it around 100 USD, and I'll probably be buying around Christmas, so sales might influence price.

Also, here is a picture inside my case, because why not!

P.S. A link to a neat and well organized OC'ing guide would be greatly appreciated! My apologies if this is a repost and has been answered elsewhere!

The 212 Evo is the best budget cooler on the market.

Grabbing some of these http://www.newegg.com/Product/Product.aspx?Item=N82E16811993027&cm_re=120mm_dust_filter-_-11-993-027-_-Product
and adding them to some of these http://www.newegg.com/Product/Product.aspx?Item=N82E16835103061&cm_re=sickleflows-_-35-103-061-_-Product

...will work.

Just as the image describes, exhaust on the top and rear... intake on the front and sides.

Thanks a lot for your response, should i get the 212+ or the evo, seeing how one is cheaper than the other im curious as to how large the difference in temps will be.

Quick Edit: the fan filters would be the only white part in my PC and would bother me a bit, is there a version of them in black, or something similar?

This benchmark;

Shows the Evo provided a 3*C drop in temperature under load...
Worth $9 to me.
