Quick Buying Tips!

Thermal Design Power: Just like the TDP of a GPU ,the thermal design power (TDP) of a CPU is the maximum amount of heat generated which a cooling system in your computer is required to dissipate.

Passively Cooled: Passively cooled CPUs have no fans or other moving parts, so they have no way to actively keep themselves cool. They rely on being placed in an environment where the temperature remains consistently below their threshold.

Fan Compatible Socket Type: Make sure your motherboard supports the type of socket your cpu cooler requires before purchasing it .

Socket Compatibility: Make sure your CPU socket type is compatible with the cooler you select.

Heatsink and fan combination: A heatsink and fan assembly is included in all boxed coolers. However, some heatsinks use a metal support bracket to mount one or two fans for extra cooling performance. If so, make sure the motherboard has mounting holes for this bracket before purchasing it .

RGB Lighting: RGB lighting can be controlled through motherboards that support RGB lighting . Some fans might have LED lighting built into them, other might not be compatible with certain types of LEDs.

Number of Heat Pipes: The number of heat pipes present in a heatsink assembly can affect the cooling performance drastically . The more heat pipes there are, the better is the performance. Fewer heat pipes lead to increased CPU temperatures and vice versa.

Price: Good CPU coolers vary widely in price, from as little as $10 up to $200 or more for high-end models such as those used by extreme overclockers and gamers who demand the best possible performance out of their systems.

Our Recommendations Best CPU Cooler for i7 9700K

Thermalright Le Grand Macho (Image credit: Amazon)

Thermalright Le Grand Macho

Best Premium CPU Coolers for i7 9700K

REASONS TO BUY

Superior cooling performance

Reasonable price

Perfect for overclocking

Heavy and bulky, making it unsuitable for mainstream users

REASONS TO AVOID

No backplate

Heavy and bulky, making it unsuitable for mainstream users

Thermalright Le Grand Macho is a massive tower-style CPU cooler, the result of Thermalright’s years of experience in designing and manufacturing cooling solutions. It is a dual tower cooler, meaning it consists of two separate heatsink blocks: one for the CPU, and another small one to cool down the VRM’s which isn’t covered by Intel’s factory fan. It features four 8mm sintered heatpipe which transfers the heat out from an aluminium base plate, where three fans (120 mm x 120 mm x 25 mm) blow air heated by contact with said base plate. The 4th fan (120 mm x 120 mm x 15 mm) blows across the VRM heatsink block.

It also includes Thermalright TY-147A PWM-bale fan which operates at 1500rpm and move up to 66 CFM of air. According to Thermalright, Le Grand Macho is capable of cooling CPUs with TDP up to 250W, and is compatible with most cases. The only downside we can see about this product is its weight: 5800g (12 lbs) which makes it unsuitable for mainstream users looking for a silent PC. However, it’s the perfect choice for enthusiast gamers or overclocker who don’t want any compromises in performance and noise levels. It has four 6mm sintered heatpipes and weighs 4kg (8.8lbs). The fin of heatsink measures 40 x 56 mm, while the height of base plate measures 5mm from its top edge to where the heatpipes begins is 56mm distance. Top-down dimension is 110 x 106 x 140 mm.

The heatsink blocks are connected by four copper heat pipes which transfers the heat from one block to another. If you wonder why two different heating blocks are placed in the same housing, that’s because this cooler was designed with Intel’s VRM specifications in mind. The base of CPU block is nickel-plated copper while the base of VRM cooling block is made out of C1100 pure copper material. The heatsink includes three TY-147A PWM fans (1500rpm, 66CFM) and one 15mm thick fan specifically for cooling down the VRM components. This huge tower-style cooler possesses 4 x 6mm sintered heatpipes which transfer the heat from aluminum fin array to each heatsink block. It also supports both Intel & AMD sockets.

Noctua NH-D15S (Image credit: Amazon)

Noctua NH-D15S

Best Enthusiast CPU Coolers for i7 9700K

REASONS TO BUY

Performance oriented design and build quality

Covers full RAM for maximum compatibility.

TDP of 95 watts is more than enough for overclocked i7 9700K

Six high quality heat pipes provide optimum cooling performance

REASONS TO AVOID

The Noctua NH-D15S is a special edition of award winning flagship model. This one is specially designed for Intel’s latest eight generation i7 9700K. It also makes full use of the Noctua’s square 150mm size fans to create more surface area and hence provide better heat dissipation. The cooler features 6 heat pipes, but still manages to keep its weight to 7 lbs making it a great option for overclocked i7 9700K. However, do keep in mind that it is a more performer oriented cooler and hence is not the best choice for silent running. The Noctua NH-D15S does cost $90, but its performance more than justifies its price tag. The reason why this model has been specially designed for i7 9700K is because of its TDP of 95 watts.

This is the maximum power that a standard Intel cooler can dissipate from overclocked i7 9700K without any hassle. But even in a worst case scenario, TDP of i7 9700K is still less than 150 watts so this cooler certainly can handle overclocked i7 9700K. The NH-D15S has a copper base, nickel plating and heat pipes made of high quality copper. As always Noctua uses their own NT-H1 thermal compound. Noctua’s NH-D15S also comes with their SecuFirm2 mounting system making it compatible with most of the latest Intel platform including LGA 115X, 2011-3 and 2066 socket.

A nice thing about Noctua is that they keep updating their CPU cooler brackets to make them compatible all their coolers even after few years. So if you are an enthusiast who likes to upgrade his/her CPU every year or so, buy Noctua now and rest assured that its mounting bracket will be updated in the future whenever you decide to upgrade your CPU. So, in short this is one of the best cpu coolers for overclocked i7 9700K when it comes to performance vs noise ratio. The only problem with this i7 9700K cpu cooler is that it is not the best choice if you are looking for something really silent. So, if Silent running is what you are looking for, Noctua NH-L12S or be quiet! Pure Rock would probably serve your purpose better.

Noctua NH-D15 (Image credit: Amazon)

Noctua NH-D15

Best Mid-Range CPU Coolers for i7 9700K

REASONS TO BUY

Amazing cooling performance

Low Noise levels

Well priced

Easy to install and fits most mid-tower cases

REASONS TO AVOID

Not compatible with current AMD AM4 socket

The NH-D15 is made by the world’s most respected manufacturer of premium CPU coolers. It has seven heat pipes, six aluminum fins per stack, and 45mm high airflow fin towers. This cooler has a height of 165mm, making it compatible with most mid-sized tower PCs. With that said, the NH-D15 is made for the top performance possible. If you are looking for an air cooler which will give you excellent cooling while maintaining low noise levels, this should be your go to choice. Noctua’s award-winning NT-H1 thermal compound also comes in the box so you can start using it right out of the package without having to buy any additional thermal paste.

Both fans have fluid dynamic bearings which allow them to run smoothly while producing very little noise. They’re PWM ready too so if you have a motherboard supporting fan speed control through PWM then these two will easily fit into your build and run under lower speeds to give you low noise levels and excellent cooling performance. If you do happen to max out the fan speeds, however, they will kick in faster and give you a higher level of cooling.

The two fans share 2 cables. One is a 4-pin PWM cable that lets you control both fans through your motherboard or CPU cooler if it has an available header for that purpose. The other is a standard 3-wire power cable which lets the fan spin at lower RPMs when they need less airflow. This saves power and lowers noise levels as well as extends their lifespan by making them run cooler due to reduced stress on the bearing system over time. This cooler is compatible with all current Intel and AMD sockets. It also comes with a low-speed adapter in the box so you can easily use it with high-RPM fans to give you that extra cooling power while generating less noise.
