I gave my Hyper 212+ to the guy I sold my X58 platform to, simply because it wasn't worth the hassle of taking apart and such. I also figured that if I can afford a new CPU cooler, why not go for it
I do plan on OCing, but not to extremes (probably just over 4GHz), and I'd like to spend in the ballpark of $50-75. I'd rather put together a LC loop but it's not worth it just to do the CPU.
I'd also like some recommendations on better fans if you guys have any.
I'm about to suggest getting another Hyper 212+. I'm sure a lot of other people here will, too.
But since you have a bigger budget this time around (and I assume you haven't completely lost interest in LC solutions), I put forth the Prolimatech Megahalems/Megashadow, Scythe Mugen-2 Rev.B, and the Corsair H50/H70. The Corsair ones are LC, the rest are monstrous tower air coolers.
I'm not sure it's worth getting a H50/60/70, everything I've heard is that the high end aircoolers like the Megahalems or Mugen are just as effective. Like gracefully said, and I agree, a Hyper 212+ is plenty for a i5-2500K. Sandy Bridge CPUs run quite cool, and don't have nearly as high cooling requirements as the LGA1366 CPUs. I've heard of people overclocking up to 4.8+GHz with a Hyper 212+ with no major heat issues.
The NH-U12P SE looks pretty decent, and same with the Thermalright MUX-120. I just wish coolers came in more colors than just metallic
I had the Fenrir before the 212+, and I actually experienced a performance increase with the 212+. My fan clips also broke (they were like bobby pins), and couldn't find new ones so that forced me to buy a new cooler.
As for the Frio, I found one on Anandtech's forums for $45 shipped, and figured if it would fit, I would get quieter fans for it. I just need to get my motherboard so I can check the heatsink height.
