Need a fancy CPU cooler or a sound card? You've come to the right place. This is where we talk about components that, while not always strictly necessary, can improve a build in very real ways.
Since Intel's Core i5-6600K and Core i7-6700K don't ship with stock coolers, you'll want to pick one from our selections below. Haswell-E builders will need to pick out a cooler, as well. Be careful to note your case's maximum CPU cooler height before buying a large tower cooler, as those huge heatsinks need a lot of space.
Cooler Master’s Nepton 120XL and Nepton 240M were taken off the market by a patent lawsuit a few months back. We've picked out some of Corsair's liquid coolers as replacements, but Corsair's products include relatively noisy fans that some TR contributors haven't liked.
Because of those challenges, we've turned to large, tower-style air coolers for the majority of our recommendations. In the past, we shied away from these coolers because of potential compatibility and clearance issues. Companies like be quiet!, Cryorig, Phanteks, and Noctua have all made living with these enormous coolers easier, though, and these modern heatsinks can often dissipate the heat of a heavily-overclocked CPU without any more noise than a closed-loop liquid cooler. Even better, they dispense with the noise of a liquid-cooling pump at idle, potentially making for a quieter system overall.

As far as entry-level coolers go, it doesn't get much better than Cooler Master's Hyper 212 Evo. This classic cooler is a very popular choice among builders. It boasts over 6,000 five-star reviews at Newegg.
A more effective option for those looking to overclock might be Phanteks' PH-TC12DX, which comes with twin fans. The reviewers at TechPowerUp found that the TC12DX has substantial cooling power for its size—it held an overclocked Sandy Bridge-E chip to just 65° C under a Prime95 load. It also tops out at just 47 dBA with its fans spinning at maximum speed. Those are quite respectable numbers for this cooler's $50 price tag.
For cases that can't swallow the Hyper 212 Evo or the PH-TC12DX, consider the Cooler Master Hyper D92. It's much quieter under load than the boxed heatsink that ships with Intel CPUs, and its 5.5" (140 mm) height works well with many microATX and some Mini-ITX cases.
The high-end tower cooler market is crowded with excellent options. If you're going to drop more than twice the price of a Hyper 212 EVO on a cooler, we think Noctua's NH-D15S is an excellent choice. This cooler is packed with clever design choices that make it easier to live with than the average hulking tower heatsink. Its offset heat pipes and cut-outs at the base of its cooling towers mean it shouldn't run into large memory heatsinks or expansion cards in the first slot of most motherboards. Its single 140-mm fan is nestled between its towers for more clearance, too.
TweakTown found that the NH-D15S can hold an overclocked Core i7-4770K to about 70° C under load at 4.5GHz and 1.14V, and its single fan only produces 33 dBA at full speed. Going by that site's considerable roster of CPU cooler test results, the NH-D15S is among the best coolers around of any type.
Big tower coolers can't fit into mini-ITX enclosures, though, and for extreme small-form-factor builds, liquid coolers like Corsair's H60, H80i GT, or H105 may be in order. Just be prepared to replace the relatively rough-sounding fans Corsair includes with a premium high-static-pressure spinner or two. Noctua's NF-F12 appears to be a favorite for that purpose.
A lot of folks are perfectly content with their motherboard's integrated audio these days. However, each time we conduct blind listening tests, even low-end discrete sound cards wind up sounding noticeably better than integrated audio. That's with a pair of lowly Sennheiser HD 555 headphones, too, not some kind of insane audiophile setup. If you're using halfway decent analog headphones or speakers, a sound card is a worthwhile purchase.
It's fine to stick with motherboard audio if you use digital speakers or USB headphones, since those handle the analog-to-digital conversion themselves. That said, even with digital speakers, the sound cards we recommend below will do things that typical onboard audio can't, like surround sound virtualization and real-time Dolby multi-channel encoding.
|Asus Xonar DSX||$53.99|
|Asus Xonar DX||$89.99|
The Xonar DSX and Xonar DX can both drive analog headphones or 7.1-channel speaker setups (either analog or digital). In our blind listening tests performed with analog headphones, these two cards sounded very similar. The DSX is the more affordable of the two, but the DX gets you Dolby Headphone virtualization in exchange for a small price premium.
