Best Overall Air CPU Cooler – Noctua NH-D15

For best overall, there was of course, a lot of factors to consider. All of the factors, actually. When all was said and done though, the behemoth, Noctua NH-D15 came out on top. Though it will set you back a cool $85.88, you are essentially getting two full CPU coolers built into one. This beast features a dual NF-A15 PWM 140mm fan setup, sandwiched with a dual radiator design. The fins are fed heat with 6 direct-contact heatpipes, and the entire array is built with an asymmetrical design for better compatibility with motherboards and components. It comes standard with Noctua’s pro-grade SecuFirm2 multi-socket mounting system for easy AMD and Intel mounting, and if you weren’t impressed with their name brand alone, they back their hardware up with a 6 year warranty, showing they have full faith in their elite-grade product.


Best Mini ATX CPU Cooler – Cryorig-CR-C7A

Cryorig R1 Ultimate Dual Tower Heatsink for AMD/Intel CPU - Black

Check Price

If you’re building a Mini-ATX rig, finding a cooler that will fit a small-sized case, while still offering top-notch cooling can seem like a daunting task. Luckily, Cryorig has exactly the sort of cooler you need, with the Cyrorig CR-C7A Top Flow Heatsink. Costing only $29.99, not only will this cooler not break your budget, but it comes ready to cool with features usually found on full-size coolers. Like many other options, this features 4 all copper heatpipes, unlike many of the other coolers you can buy, this comes in an incredibly small 47mm height profile, able to fit in even the smallest of HTPC of mini-ATX cases.


Quietest CPU Coolers

Nothing can kill the thrill of a new rig faster than loading your first benchmark or stress testing software to find that under load the cooling sounds like a vacuum cleaner or jet engine. There are three coolers that stand out for being EXTRA quiet, if finding a nearly-silent system is what you’re aiming for. First, the Noctua L-Type Premium Quiet CPU Coolers, including the NH-L9, and NH-L9x65 (nearly the same, besides a height difference, to suit micro or mini sized cases). They boast not only top-quality fans, but a form factor that promises no RAM overhang.

A second option, if space is not as much of an issue, is the Thermalright HR-02 Macho. This beast of a cooler boasts 6 cooper heatpipes, and a Thermalright TY-140 Utra-low noise 900~1300RPM PWM-Fan, which runs silently, if at all. The huge size of this cooler cannot be ignored, but with so much metal for cooling, the fan barely needs to spin up to keep it nice and cool.

The last good option for finding the quietest cooler option is the Cooler Master Hyper 612 Ver.2. This is the ‘just right’ of our ‘Goldilocks and the 3 coolers’ story, falling in between the two other options in terms of size and cooling. It still offers a full 6 copper heatpipe cooling solution, and with the intelligent 120mm PWM fan, never spins any faster than it absolutely has to, leaving you with no more noise than absolutely needed.

Best CPU cooler for i7 6700k

For cooling the new i7 6700K there are two real options to consider. If you need the absolute best cooling option without any compromise, you aught to look at the ‘be quiet!’ brand Dark Rock Pro 3. This beast of a CPU cooler not only looks like an obelisk, it combines cutting edge cooling technology with hardcore metal aesthetics. The manufacturer designed this cooler with their proprietary dynamic wave-contour cooling fins that feature small dots on the surface to increase air circulation and contribute to high convection efficiency.  It has 2 120mm fans included, and clips for a 3rd for hardcore air cooling.

Of course, if you’re looking for a cooling solution that won’t run nearly 90 dollars, you may be nearly as happy with the performance of the Cryorig H7 tower cooler. Though this only comes with 3 heatpipes, the company still provide its’ proprietary Hive Fin System for airflow optimization, air turbulence reduction, added heat dissipation area, as well as the Jet Fin Acceleration System. Not only adding top notch cooling (for a very reasonable 35 dollars), but stability for vertically mounted systems.


Best CPU cooler for i5 6600k

If your rig is running on the i5 6600K, the cooler for you is the Noctua NH-D15. Noctua has a good reputation for quality coolers, and this cooler is no exception. This cooler has a 6 heatpipe dual-radiator design, allowing each end of the heatpipes their own radiator to dissipate heat.  It comes with a pair of NF-A15 PWM 140mm fans, which not only provide excellent cooling, but do so nearly silently. The asymmetrical design not only looks sharp, but allows for easier hardware compatibility with ram heatsinks and north or south bridge heatsinks. With a lot of features, and a really nice look, this is an excellent cooler for the i5-6600K

The i7 770K CPU is a great piece of hardware, and to cool it you want something reliable and efficient. The Noctua NH-D14 fits both of those criteria, looks good doing it, and won’t break your budget. It’s got a pair of 120mm fans that keep the dual-radiator design nice and cool without using much spin. There are 6 total heatpipes, allowing for amazing heat dissipation, with each heatpipe having each end in a different radiator. The cooler features beige and crimson fans, and a silver heatsink that looks great in most any build.

Best CPU cooler for overclocking

If you’re looking to push your CPU to the limit with overclocking, there are two great options available, depending on your budget. For the big spender, you can’t beat the NZXT Kraken X61. This glorious piece of cooling technology boasts the world’s first integrated variable speed pump, which keeps noise to a minimum during use without sacrificing top end pump power. The water cooler has a 280mm radiator (a pair of 140mm fans included), and integrated Hue and digital fan control software so you can pick a glow that suits your rig perfectly.  For ease of installation and improved airflow, it even has extended 16″ tubing and premium black sleeved cables. A more budget-friendly option, or for those not interested in water cooling, you simply cannot beat the Hyper 212 EVO. This world-famous air cooler has a simple single radiator with 4 copper heatpipe design, and a 120mm PMW fan. Despite simple looks and design, this cooler has a reputation for being top notch when it comes to overclocking and cooling.

CPU Cooler Buyers Guide

How much does a good air CPU cooler cost?

As with any component, cost is an important factor for your cooling decision.  Air coolers, as a general rule, are usually less costly than their liquid counterparts, but can still come in very high-end costlier options too. Depending on how much cooling you need, and what chipset you’re running, you can get air cooling options as low as $15 these days, and that’s including some name brands too, not just no-name generic products. That said, if you have the cash, you can easily spend upwards of $85+ dollars on a top-tier air cooler with double-radiator designs and dual fans for massive cooling. If you’re looking to overclock, or know you’re going to be pushing your CPU long and hard, it’s probably worth looking at the top end, if, of course, you’re a die-hard air cooling fan (pun intended), and aren’t looking for a liquid cooling alternating.  For those looking for a bare-budget rig and still need decent cooling though, you still have plenty of options (ie the Hyper EVO 212). The benefit of air cooling is simplicity and how budget friendly it typically is.

What are the benefits of an aftermarket air CPU cooler vs a stock CPU cooler?

Some people, especially those just breaking into the gaming or overclocking world may wonder why bother replacing a perfectly good stock CPU cooler with an aftermarket solution. It came with the CPU right? Shouldn’t it be specifically designed to cool it? Well, the answer is actually pretty simple. Manufacturers are in a constant struggle to keep costs low, and thusly, package coolers that are the bare minimum needed to cool their CPUs. If you’re going to push it, want to enable full turbo speeds or overclock, however, it’s almost always prudent to invest in an aftermarket cooler. The benefit of zero additional cost for a stock cooler cannot be overlooked, not to mention you know the thermal grease, and mounting brackets will be pre-installed and ready to install. Aftermarket coolers, however, give you a plethora of options. You can really get the most out of your CPU performance with a quality air cooler, and despite having to shell out some extra cash, and a potential need for a bracket install for mounting, the benefits of added CPU life, and making the most of a full size (or tiny sized) case is most always worthwhile.

What to look for in a good CPU cooler

1. Size of the Cooler/Clearance of Components, etc

It’s important when choosing the best air cooler for your system to keep in mind the physical layout of your motherboard, and how the cooler might fit in with the motherboard heatsinks. With some motherboards now coming with extremely fancy and well-built north and south bridge cooling blocks, it can be important to check the clearance height of your cooler. Also, with some of the larger memory heatsinks, it can be wise to make sure your cooler does not prevent you from using some or all of your memory slots! Heres a great resource to learn more about different PC form factors.

2. Noise levels (RPM levels)

Another important factor to consider when choosing a CPU cooler is the noise it produces. It can be embarrassing to walk into a LAN party with a slick looking rig, only to power it on and have everyone need ear plugs because it sounds like a jet engine. The RPMs of the included fans with an air cooler, and whether they come with variable speeds can be a key element to keep in mind when you make your final decision.

3. Size of the Cooler needs to be able to fit in case

It does no good getting a dual-radiator 140mm beast of a heat sink, only to discover that, lo and behold, it doesn’t quite fit in your Mini-ITX case! Pay close attention to the height of your air cooler when putting together your new system. Also, note the distance between your top motherboard edge and the case’s top side. Typically they should always allow enough room, but with some of the more unique case designs, and the monster coolers available now, it doesn’t hurt to double check.

What is a liquid cooler is and how do liquid CPU coolers work?

For those who are die-hard air cooler users, or new to system building, air coolers can seem like a scary and dangerous thing (liquid INSIDE your PC???). These days though, there is no need to be mystified or afraid, and many manufacturers offer liquid cooling systems that are completely self-contained and are no more difficult to install than a typical air cooler and case fan. A liquid cooling system consists of a radiator, typically with an attached fan to keep the liquid running through it cool, a copper mounting plate for the CPU with a waterpump to keep the liquid moving through the system, and tubing to transport the liquid between the CPU and radiator. Some more intricate systems also contain a separate reservoir for the liquid, but a traditional pre-built liquid cooler will not.  Because the copper heatplate has a closed unit for the liquid to run past, and the radiator allows for the liquid to be cooled at very fast speeds, a liquid cooler allows for much faster heat dissipation than most air cooling counterparts.

What are the benefits of liquid CPU coolers?

Unlike the air coolers that come stock with most CPUs, or the aftermarket options available, liquid cooling is considered the ‘next level’ for those who are serious about cooling their systems. Although most liquid coolers still come with fans to push air past the radiators, those fans typically run at rather slow speeds, allowing for the liquid cooler to run very quietly. If a near-silent rig is your goal, it’s almost mandatory that you go this route. As for actual cooling, liquid cooling systems simply can not be beat. With options for small-sized systems as small as 120mm, and giant radiators that can take three entire 120mm slots, like a monolith of cooling power, they can be used in any system, big or small. They don’t have to break the bank either. You can get quality air cooling systems for as little as $60, which can usually be squeezed into a build’s budget. Since these days the installation of liquid coolers can be as simple as a traditional air cooler on the CPU, and a fan on the case (with some extra radiator attached), there’s a of of good reasons for taking the plunge!

How much do liquid CPU coolers cost?

It can be easy to assume with all of the benefits of liquid cooling that it would be wildly expensive to get into it. Luckily, there are a plethora os systems available, and for as little as $65 , you can be the proud owner of a simple to install, but still very effective Corsair Hydro Series H60 liquid cooler. For those who want a little more oomph, you can definitely go big, with the 360mm beast of a radiator included too. This option, which will set you back $120, is the  Thermaltake Water 3.0 Ultimate 360mm AIO Liquid Cooler, one of our picks for best performance liquid cooler also! If you’re looking for the ‘just right’ option, split the difference with the Corsair Hydro Series H100i v2 Extreme, a 240mm cooler that will give you superb performance, at a moderate $109.

Air cooling vs Liquid CPU cooling? Which one is better?!

When you get down to it, there are plenty of reasons for both air coolers and liquid coolers, and there really is no reason to try and decide which to consider ‘the best’. It can all depend on your situation, and price, is always a factor. If you’re putting together a bar-bones super budget build, there’s nothing wrong with finding a reasonable $25 air cooler and still getting solid performance out of your CPU. Also, some people prefer the gaudy or big-metal look some of the bigger air coolers offer you, while some people like the black plastic or braided tubing and radiators that come with most pre-build liquid systems. It’s hard to compare if you want the absolute best cooling, because liquid cooling takes the cake there, hands down. Also, to be fair, even if it’s a mainstream technology, if you’re just not comfortable with ‘liquid’ inside your PC, than you’re not comfortable with it, and there’s no reason to keep yourself up at night about it!  It’s nice that we have so many options, and in the end, if budget is your biggest concern, you’re almost certainly going to be looking for an air cooler for your rig (make sure to check those dimensions so it fits!), but if raw power and cooling performance, or if noise level is your biggest concern, it’s going to be liquid coolers taking the prize every time.
