NH-D14 is one of the best cooler in the market, great quality and performance, I've upgraded from Zalman 9900 Max: difference is huge, so it worth its price.... it is better even than some water cooled kits.
Noctua NH-U9B SE2, absolutely great value (cooler + NT-H1 Thermal Paste + two NF-B9 fans) and it's not too big/heavy, which for me is really good. It's also extremely quiet and the cooling performance is WAY better than the stock Intel cooler. I even used one of the fans as rear exhaust for the case to save money (the second fan mounted on the cooler only shaves a couple of degrees off the CPU temperature, according to the manual). It also comes with several cables to choose your fan rotation speed (I have it at minimum of course).
XIGMATEK Gaia SD1283 120mm Long Life Bearing CPU Cooler with Arctic Silver 5. Used Xigmatek for the the last 6-7 years at least through my builds. Very similar to the 212 Evo. As I type this in a hot room my CPU sits at: 2 cores at 26º, 1 at 25º, and 1 at 24º. I am good with that. The cores never go much higher than the high 30's even when gaming. Have seen 50ºC once when I was actually encoding and jumped into a (highly un-optimized) game with my friends.
Custom built LC system bought mostly from frozencpu:
XSPC RX360 Extreme radiator, XSPC EX 140mm radiator, Swiftech MCP655 variable speed pump, Raystorm X99 Variant (CPU block), EK waterblocks and backplates for R9 290X, Bitspower Quick-Disconnects for the GPU's, some Phobya connectors/angle joints, some XSPC high flex tubing, and some Primochill Pure coolant. That's at least the basics of my system.
