I'm not an extreme overclocker, but I do like to have the option to overclock if I need to, and I want a comfortably cool CPU. I've been looking at the Hyper 212+ and the EVO version since they are very cheap but I also have been considering liquid cooling as well. The new Corsair Hydro series like the H90 look appealing, but I've heard good things as well as some bad things about them. There's even the Noctua NH-D14 which is $80, but seems pretty nice. The most I'll probably overclock to is 4.2-4.4 GHz, which is moderate compared to something like 4.8 or 5.2. I'm willing to spend up to $60-80 for an air cooler and $100 if I get a liquid cooling system. What do you guys suggest?
If you are going to only o/c to 4.2-4.4GHz, then you do not need high performance air like the NH-D14 (that I use on my 2500k for 4.83GHz), and you definitely do not need water. The 212 Evo will do you fine considering you likely won't even be dealing with bumps in Vcore, where heat management starts becoming an issue with higher GHz overclocks.
For 80 dollars the NH-D14 is the best choice. The corsair hydro series will cool better but they're louder and there's the issues with the firmware that can cause grinding/screeching from the pump fans.
The hydro is a lottery, go with the NH-D14, it keeps my stock 3930k under 45C at all times(excluding stress tests) with one fan mounted on it(it comes with 2).
Hey thanks for the answer, sadly I already bought the Antec Kuhler H2O 620 for $70. It works great, though! I believe all of those lower end closed-loop water cooling systems are designed by the same company, because the Kuhler 620 is VERY similar to that Cooler Master one (And the H55/H60 as well).
Yup, most of the CLC's on the market are basically just re-branded Asetek designs. The ones that aren't (Swiftech H220) are currently being sued by Asetek for patent infringement, so that likely wont change anytime soon.
