Best CPU Coolers for PC in 2024

Aftermarket CPU coolers are now more of a necessity than a novelty, as AMD’s 7000 series and Intel’s 13th and 14th-generation CPUs continue to push thermal boundaries. This means buyers must be selective when looking for the best hardware to meet the requirements of high-performance modern processors. Fortunately, there is a diverse selection of fans, heatsinks, and AIO liquid coolers that not only perform well but add style to a gaming rig.

Intel vs. AMD: Which CPUs are better?

Trying to choose between an Intel or AMD CPU? Here’s our comparison of how they break down against each other!

Focus On These Factors When Choosing a CPU Cooler:

There are a few factors that buyers should consider when purchasing a CPU cooler. They include:

• Compatibility: Each time a new generation of Intel or AMD processors arrives, it forces CPU coolers to adapt to different mounting components. Ensure that any potential CPU cooler has updated its accessories to handle the shifting dimensions of CPU sockets.
• Cooling Method: The most popular form of CPU cooling is air cooling, which relies on a combination of fans and heat sinks to dissipate heat from processors. Even so, liquid cooling, a quiet and effective way to control overclocked CPU temps, has become more affordable in recent years. Finally, passive air cooling has limitations but ditches all fans and exclusively uses a heatsink, making it ideal for completely silent builds.
• Overclocking: The coolers that ship with many Intel and AMD CPUs are adequate for controlling the temperatures of these processors at stock settings. Once a gamer decides to overclock a CPU, a more powerful cooler is necessary to deal with the added heat generated by a processor. Some coolers enable users to push their CPUs to their breaking point, while others can only handle light to moderate overclocking.
• Noise Level: Manufacturers often rate the noise levels of their coolers in decibels, though exact numbers depend on specific builds and testing environments. Regardless, certain CPU coolers produce more audible noise than others, with cooling performance not always corresponding to noise levels.

The Noctua NH-D15 is a best-in-class contender among CPU air coolers and is the successor to the popular NH-D14. It has huge shoes to fill but meets the challenge with a no-frills approach to thermal performance. Coming in the standard Noctua brown color (it does sell in a different black theme to match the majority of PC cases), the NH-D15 dominates most of the tests one can throw at it. Thanks to its heat-pipe tower structure, the cooler delivers stellar cooling performance with two powerful, silent fans.

The NH-D15 comes with excellent Noctua NT-H1 thermal paste and low-noise adapters. This Noctua cooler also discards any attempts to push RGB or ARGB support, which is quite popular with most people assembling a gaming PC. Note that if a buyer goes for this cooler, check its size specifications. It’s larger than it looks in the pictures, and some mid-tower cases take liberties with the amount of space they offer. Still, provided that it fits in a case, the Noctua NH-D15 quietly outputs a jet stream of air that ranks it as the overall best CPU cooler.

These budget cases are great options for first-time PC builders with attractive styling and future-proof expandability.

The ID-Cooling SE-214-XT is a compact air CPU cooler utilizing a four-heat-pipe design that maximizes contact between the heatsink and CPU. The heatsink has a micro wave orientation on its aluminum fins, enlarging the heat dissipation area. While the ID-Cooling SE-214-XT isn’t the smallest cooler, it’s compact enough to avoid blocking memory slots on most gaming motherboards.

For the minuscule asking price of the SE-214-XT, a buyer may not expect the air cooler to look like a premium component. Nevertheless, ID-Cooling has included an ARGB fan that gamers can connect to a motherboard’s 5V 3-pin header. The fan is also PWM, meaning that a PC’s BIOS, as well as a variety of other software, can adjust speeds depending on current CPU temps. In addition, the heatsink ships with an all-black cover to make the SE-214-XT’s look fit in cases whether it’s turned on or not.

The instructions that come with the SE-214-XT could use some more detailed explanations. Regardless, this air cooler is compatible with Intel’s latest LGA 1700 chipset, as well as the LGA 1200/115X, and AMD’s latest processors.

As far as its overall performance, the ID-Cooling SE-214-XT can’t quite compete with some of the more expensive coolers. Even so, it outputs a healthy 68.2 CFM airflow but not without reaching noise levels of up to 30.5 dBA. Gamers will want to make sure that their case has sufficient insulation to absorb some of the fan noise, but the value and style that the SE-214-XT brings at its ultra-cheap price point is irrefutable.

Cons

• Somewhat noisy
• Some versions difficult to find in stock

For newcomers to PC building, how even a relatively simple air cooler works can cause some confusion. Still, some concepts are just common sense, like the fact that two fans or two cooling towers can provide more effective cooling than just one. A dual-tower, dual-fan air cooler like the Thermaltake Peerless Assassin 120 takes up considerable space on a motherboard but can rival the cooling performance of even some liquid coolers. Even better, the Peerless Assassin 120 is very competitively priced and comes in several colors and ARGB fan variations.

With the Peerless Assassin 120, Thermaltake didn’t just take a conventional single-fan air cooler design and multiply it by a factor of two. The cooler sports six antigravity heat pipes, allowing it to cool CPUs effectively, regardless of their orientation in a PC case. When designing coolers of this size, special attention must be given to the possibility of blocking memory slots and other vital motherboard components. Thermaltake confirms a memory clearance of 46 mm in most standard configurations, enough to accommodate most sticks. However, with two fans, one will likely have to sit directly on top of the memory, though it’s easily removed from the heat sink with some metal clips.

Few manufacturers directly market CPU coolers to competitive gamers, but the Arctic Freezer 34 Esports Duo aims to enhance the hardware these pros rely on. If buyers are searching for a cooler that can match their favorite esports team’s colors, the Freezer 34 Esports Duo will suit them with various styles. Arctic’s cooler has a dual fan single tower design that produces enough airflow to cool many overclocked CPUs without generating excess noise.

With the Freezer 34 Esports Duo, a pair of BioniX P-fans surround the 54-fin heat sink in a proven push-pull configuration. The front fan forces cool air against the heat sink with tremendous static pressure. Then, the rear fan exhausts heat at a maximum of 2100 RPM. Compared to past Arctic Freezer coolers, the manufacturer’s latest fans are optimized for lower power consumption and minimal vibrations. The result is that even at high loads, the Freezer 34 Esports Duo will rarely exceed the 24.3Db(a) noise threshold.

Another reason why the Freezer 34 Esports Duo performs so well despite its fairly compact heat sink is its direct-touch heat pipes that attach directly to where the most heat accumulates. Previously limited in what processors the cooler was compatible with, the Freezer 34 Esports Duo now ships with hardware supporting virtually every common CPU on the market. However, while installation is usually quick with a few parts to work with, the manufacturer could improve their packaging to protect all the cooler’s components better.

In the end, the Freezer 34 Esports Duo accomplishes its goal of providing enough cooling for esports pros to game at high framerates. Also, it’s one of the most affordable air coolers in this guide, ditching fancy RGB effects for stylish color schemes that look spectacular in any gaming rig.

The Best Case Fans For Your Gaming PC in 2023

Keeping temperatures in check is crucial in a gaming PC. Having adequate airflow ensures that components can perform to the best of their potential.

What separates higher-end liquid coolers from cheaper models is often the motor inside the water block. Despite its relatively compact size, the three-phase motor used in the MAG CoreLiquid E360 is enough for excellent performance at high CPU loads with minimal vibrations. Evaporation-proof tubing connects the water pump to a 12-pairway radiator, which can operate in several different locations in most mid and full-tower cases. In an efficient liquid cooling technique, the pump will send water heated by a CPU toward the radiator, which will dissipate the heat using the three 120 mm fans. The cooled liquid will then be sent back toward the water pump to reduce CPU temps once again.

Installation of the MAG CoreLiquid E360 is generally smooth, but gamers may have to read a manual from a mobile phone screen since there are no printed instructions. MSI provides the mounting hardware for the most recent Intel and AMD processors, and the small but powerful water block avoids preventing access to critical components.

The performance of the MAG CoreLiquid E360 is excellent and comes close to matching the cooling levels of the most expensive AIO liquid coolers. By the same token, buyers won’t experience a significant jump in temperature reduction compared to some single or dual-fan budget coolers. Still, it’s hard to top the MAG CoreLiquid E360’s ARGB effects, offering a distinctive look with exceedingly bright fans and a water block that stands out in any rig.

Pros

• Impressive build quality
• Fully-committed white styling with finishing touches
• Easy installation

Cons

• Louder than some similar coolers
• Memory clearance could be an issue

With so many black enclosures looking alike, white PC cases have steadily risen in popularity. However, an all-black CPU cooler can instantly ruin the universally white look a system builder is after. The DeepCooler AK620 is faithful to this trendy color scheme and can survive the stress of cooling the most potential processors.

The heat pipes, heatsink, and dual 120 mm fans used in the AK620 are all coated in white. A teal-colored DeepCool logo in the center of the fans and the top of the heat sinks are the only exceptions to its consistent styling. The manufacturer also added some nice finishing touches to the cooler’s build, including cover plates capping its fairly chunky dual tower design.

While the AK620 may stand out most for its looks, it’s no slouch with the generous airflow its fans generate. Matrix fins in the heatsink expertly deal with excessive heat while reducing its footprint on a motherboard. Regardless, there are dual tower/fan air coolers that are slightly more compact, so buyers will want to ensure that their RAM sticks will have proper clearance.

Cooling performance and noise levels are more than acceptable with the AK620, even if it doesn’t dominate the best CPU cooler contenders. The AK620 makes its mark with high-quality materials and styling that make it a highlight of any build.

Noctua NH-P1

Best Passive CPU Cooler

The Noctua NH-P1 takes on the difficult task of completely silent and fanless PC cooling and manages to exceed expectations. This passive cooler utilizes six heatpipes and extra large and spaced-out heatsink fins for maximum heat dissipation. Thanks to its asymmetric design and layout, the NH-P1 will not block memory modules on many motherboards or interfere with PCIe slots. The end result is effective passive cooling that can handle high-end CPUs at stock settings, without the noise or the dust accumulation that plagues active air CPU cooling systems.

Pros

• Completely noise-free
• No fans that collect dust
• Outstanding build quality

Cons

• Not intended for overlocked CPUs
• Huge heatsink

Admittedly, passive CPU coolers aren’t popular with most gamers or system builders. Unlike active air coolers with fans, the Noctua NH-P1 uses no fans, relying entirely on its extra-large heatsink. The benefits of this approach are obvious: offering silence rather than a potentially disturbing fan that can interrupt games and collect dust. Regardless, passive CPU coolers only make sense in cases that promote ample natural airflow with minimal or no fans. Also, while overclocking a CPU with the Noctua NH-P1 is not wise, the cooler can keep some of the latest CPUs running with stock settings at safe temperatures.

There are some rather large air CPU coolers on the market, but they still can’t match the size of the Noctua NH-P. Obviously, the lack of fans means that the heatsink has to do most of the work to dissipate CPU temperatures. As a result, the heatsink has thick fins on its exterior that are spread out more than normal to exceed the performance of what these components are usually capable of.

Buyers may think that the gigantic Noctua NH-P1 is sure to block memory or PCIe slots on their motherboards, but because of its asymmetrical design, the heatsink’s fins are set toward the top of a board. This layout also minimizes the chances of memory sticks being too tall to nestle underneath the cooler. Even so, potential buyers should check out the motherboard and CPU compatibility lists at Noctua’s website to avoid disappointment.

The Best DDR5 RAM for Gaming PCs in 2023

DDR5 is all the rage of late, but not all RAM kits are made equal. Finding the right RAM can significantly help boost a PC’s performance.

Fans aren’t completely barred from use with the Noctua NH-P1. The manufacturer suggests that quiet 120 mm fans can be attached to the cooler and then be configured to spin only when CPU temperatures reach near dangerous levels. This approach may ruin the appearance of a completely fan-less build, but it’s a compromise that allows users to stress their CPUs more than what is normally possible with passive cooling.

The silent Noctua NH-P1 is undoubtedly more of a niche cooling solution but can come close to matching the performance of lower-powered air coolers. For any buyer striving for a legitimate stealth build, its considerable expense seems more reasonable, thanks to Noctua’s remarkable build quality and reputation for durability.

How To Pick The Right CPU Cooler?

Unlike some PC components, there is a fairly straightforward process for picking a CPU cooler. Ultimately, it comes down to a handful of considerations.

Compatibility

Thanks to modern engineering, most CPU coolers can adapt to the performance requirements of the latest processors. The Noctua NH-D15 was chosen as GameRant’s best CPU cooler partly because it accommodates nearly every processor on the market. For buyers concerned about a large heatsink blocking their memory slots, the Noctua NH-D15 can still effectively cool CPUs with only one fan.

Cooling Method

CPU coolers employ a variety of methods to control the temperatures of power-hungry processors. Air coolers operate using fans in conjunction with heatsinks to dissipate heat generated around a CPU socket. The most potent air coolers, like the Thermalright Peerless Assassin 120, utilize a dual fan and dual tower heatsink design to output a tremendous airflow.

AIO liquid coolers such as the ASUS ROG Ryujin III 360 take a different approach to limit the amount of heat a CPU generates. A water block positioned on a CPU socket, a water pump, and a radiator continuously move cool liquid over a CPU while sending the heated liquid toward a radiator with fans to dissipate the heat. The ROG Ryujin III 360 also includes a snazzy 3.5-inch LCD screen to monitor temperatures and system information in real time. Budget buyers aren’t shut out from the water cooling world either, with NZXT Kraken 120 offering surprisingly capable performance with just a single fan.

Liquid coolers tend to operate with less noise than air coolers. For those buyers who demand absolute silence in their builds, a passive air cooler like the Noctua NH-P1 may be the answer. The NH-P1 can’t match the performance of many air and liquid coolers, but it is an option for buyers looking to run CPUs at stock settings.

Overclocking

After boosting the clock speeds and voltages of CPUs in a BIOS, a PC may not run properly for long without an adequate CPU cooler. A mid-range liquid cooler like the MSI MAG CoreLiquid E360 is suitable to see just how much a processor can be overclocked. However, even air CPU coolers, including the Cooler Master MasterAir MA612, can allow for at least moderate overclocking, depending on the specific processor and amount of airflow in a case.

Noise Level

Modern CPU coolers can reduce processor temperatures drastically without causing abundant noise or vibrations. While AIO liquid coolers can operate in stealth mode in a case, the be quiet! Dark Rock Pro 4 is an example of an air cooler that runs just as quietly. The Ninja 5 benefits from a pair of Silent Wings 3 fans that combine to maintain reasonable CPU temperatures without distracting noise.

CPU coolers also differ dramatically in appearance, with some choices matching a black, white, or pink case better than others. All-white enclosures now have a perfect companion in the snow-colored DeepCool AK620, providing exceptionally cool and quiet performance.

Whether a buyer is looking for a cooler that can become a focal point of a rig or cool CPUs without attracting attention, there is an ideal candidate discussed in this guide.

FAQ

Q: Is an air cooled or liquid cooled CPU cooler better?

This is a question that will not have a single answer. AIOs are perceived as generally superior overall but good CPU air coolers can do a similar, if not a better job at times. The real question is whether your case can move the heat being pulled away by the CPU air cooler out. That means that a good CPU air cooler might also need help from the case to keep the ambient temperature inside the case lower to work optimally. AIO coolers do not generally have that restriction since they are mounted at the exhaust or intake points of a casing.

Q: Why do some high-end CPU coolers not have RGB?

Because RGB is purely aesthetic and adding or removing it from a CPU cooler does not benefit or degrade performance one way or another. Performance PC parts by companies such as Noctua and BeQuiet! Focus on maximizing their cooling effectiveness with any aesthetic gains being a secondary factor for their coolers. As a result, the approach they go for when it comes to their coolers is less-is-more, and it does work – Asus’s earlier version of the Ryujin II sported Noctua fans, backed by popular consumer demand.

Q: Why do I need to purchase cooling products if I have a stock CPU cooler?

The stock CPU fans and heatsinks that ship with many Intel and AMD CPUs are fine for many users. However, if you wish to overclock a CPU, the basic stock coolers may not handle the excessive heat that an overworked processor generates.
