I'm going to start overclocking my i5 2500k and need to know which heatsink I need to replace the stock intel heatsink. I have an MSI p67a-gd65 mobo with gskill ripjaws RAM. My case is HAF 922. My first choice was the the hyper 212 evo but I read it wouldn't clear the RAM heatsinks. So now I need to know which heatsink will have sufficient cooling for an overclock somewhere around 4ghz and be able to clear the RAM heatsinks. Any help is appreciated.

The Evo will be fine.
I have a 212+(basically identical dimensions) with Ripjaws all 4 dimms filled.
Had to slide the dimm side fan up maybe a quarter inch.

Okay, when you say you had to slide the fan up, do you mean just move where it's located on the heatsink? Sorry if that's a dumb question, I've never worked with aftermarket heatsinks before. Also, are there any other heatsink recommendations for a 4ghz-ish overclock?

Depending on your price range I recommend the CM 212+ for $25-$30...don't get EVO its not worth the extra money. This is good for 4.5ghz at 1.35v...temps won't exceed 70C. Make sure you add a 2nd fan for push pull. They include the mounting for the 2nd fan already

You might even find a good deal on the corsair A70...both have fairly similar performance for same price depending on who has a deal going.

for $60 get NZXT havik...this will allow close to 5ghz...with same temps..don't exceed vcore beyond 1.38v no matter what...its not good for 24/7 use.

for $75-$80 get noctua NHD-14..this thing will let you overclock till 5ghz without issue (temps above 70-75c)..as long as you don't increase the vcore beyond 1.38v. The main thing with this one is that its probably the most silent cooler on the market with this level of performance. Similar coolers are phantex 140mm cooler and thermalright silver arrow.

The Noctua is a bit more than I wanted to spend, was looking to keep it under $70, preferably less. Out of the other ones listed though, would any of them clear the RAM heatsinks or would they all have to be adjusted? Also, will I have to buy extra fans with the heatsink or will they come with all the fans I need? Sorry if that's a dumb question but again, I've never worked with an aftermarket cooler.

Yeah the fan just slides up the heatsink to clear your closest ram stick.
The Evo is worth the extra $5 imo and will cover overclocks to 4.5GHz no problem.

Spending more then $50 on a cooler for a 2500K is a waste of money!

Yea all the coolers I listed clear the ram. Infact the NZXT havik may not even get close to the ram at all. checkout the latest video on overclock3d.net.

Thanks for all the input everyone. I decided to go with the EVO because it sounded like the best bang for the buck.
