For most gaming PCs, a good dual-tower air cooler is the sensible starting point: it can handle mainstream Ryzen 5 and Ryzen 7 systems and many Core i5 and Core i7 builds without a pump or radiator. Choose a 280 mm or 360 mm all-in-one (AIO) liquid cooler when your priority is sustained cooling for a high-power CPU, or when your case and build goals make an AIO a better fit. The right choice depends on CPU power settings, noise targets, and exact case and component clearances—not just the cooler’s category.

Air cooler or AIO: which makes sense for your PC?
| Consideration | Air cooler | AIO liquid cooler |
|---|---|---|
| Cooling capacity | A strong dual-tower model is generally enough for mainstream gaming CPUs and many mixed-use systems. | Larger 280, 360, and 420 mm radiators can provide more capacity for sustained high-power workloads. |
| Noise | Noise mainly comes from fans, which can be tuned with a fan curve. | Noise comes from fans and the pump; a large radiator can allow slower fans, but does not guarantee a quieter system. |
| Complexity and upkeep | No pump or coolant loop; usually dust cleaning and, eventually, possible fan replacement. | More components and possible failure modes, including pump failure, unusual pump noise, and leaks. Consumer AIOs are generally sealed rather than intended for routine refilling. |
| Installation and fit | Requires room above the CPU socket and can overlap RAM or nearby components. | Moves the main heatsink mass away from the socket, but requires a supported radiator location, room for tubing, and sufficient clearance. |
A good air cooler is often the more straightforward choice for a gaming PC. An AIO is worth considering when sustained rendering, encoding, compiling, or simulation keeps a high-power CPU loaded for long periods; when you want less heatsink mass around the socket; or when appearance and integrated features matter. Neither type is risk-free: air-cooler fans can fail, while an AIO adds a pump and liquid loop. Check the specific warranty terms for your region rather than assuming coverage is uniform.
Best air coolers
Thermalright Phantom Spirit 120 SE: best overall air choice
The Phantom Spirit 120 SE is a dual-tower cooler with seven 6 mm heatpipes. Thermalright lists it at approximately 154 mm tall and supports AMD AM4 and AM5, along with Intel LGA115x, LGA1200, LGA1700, and LGA1851. It is a strong choice for buyers who want high-end air-cooling performance without paying for a premium brand. Check the exact variant: Thermalright sells similarly named versions that can differ in color, lighting, fans, and hardware. Its large footprint can also cause RAM, VRM heatsink, or case-panel clearance problems. Thermalright’s Phantom Spirit 120 SE specifications.
#1 Best Overall
- Cool for R7 | i7: Four heat pipes and a copper base ensure optimal cooling performance for AMD R7 and Intel i7.
- Quiet Cooling Fan: SickleFlow 120 Edge with Dynamic PWM control (690–2,500 RPM), designed for low noise and peak cooling performance.
- Simplify Brackets: Redesigned brackets simplify installation on AM5 and LGA 1851|1700 platforms.
- Versatile Compatibility: 152mm tall design offers performance with wide chassis compatibility.

Thermalright Peerless Assassin 120 SE: best value air cooler
The Peerless Assassin 120 SE is a six-heatpipe dual tower that Thermalright lists at 155 mm tall, with AM4, AM5, and several Intel socket generations supported. It is a sensible value pick when its exact version costs less than the Phantom Spirit or when it is easier to find. The Phantom Spirit is a close alternative and may perform similarly or somewhat better depending on test conditions, so compare the exact variant and current retailer price rather than treating the family names as a guarantee. Check RAM clearance, since its front fan may need to be raised over tall memory—raising it increases the cooler’s effective height. Thermalright’s Peerless Assassin 120 SE specifications and independent Peerless Assassin testing provide further detail.
Noctua NH-D15 G2: best premium air cooler
The NH-D15 G2 is for buyers who value premium fans, mounting hardware, and support more than the lowest price. Noctua’s documentation specifies eight heatpipes, NF-A14x25r G2 fans, the SecuFirm2+ mounting system, included thermal compound, and a six-year warranty. Its variants are not interchangeable: the standard, LBC, HBC, and chromax versions should be checked individually. Noctua offers different base-convexity versions for different heat-spreader characteristics, notably AM5 versus Intel LGA1700 CPUs that may have a deformed or flattened heat spreader. The cooler is large, remains expensive relative to Thermalright’s value models, and still needs a careful RAM and case-clearance check. NH-D15 G2 specifications and installation and mounting guidance.
Arctic Freezer 36: budget option for mainstream CPUs
The Freezer 36 is worth considering for mainstream Ryzen 5 and Ryzen 7 or Core i5 builds, especially when a bulky dual tower is unnecessary. Gamers Nexus tested it on AMD and LGA1700 platforms. It is not the pick for an unrestricted Core i9 workload or heavy overclocking. Check the exact model’s included socket hardware, height, and motherboard clearances before ordering.

Arctic Liquid Freezer III 360: best for sustained high loads
The Liquid Freezer III 360 is the strongest AIO recommendation here for sustained high-power cooling, based on 2024 independent testing that found leading results in its methodology, including noise-normalized comparisons. It includes MX-6 thermal compound and integrated fan wiring. Arctic lists AM4, AM5, LGA1700, and LGA1200/115x compatibility with the relevant hardware, and says Intel tested and confirmed the cooler on several high-power LGA1700 CPUs. Its unusually thick radiator is the main practical caveat: a case advertised as supporting a 360 mm radiator may still lack room for this radiator plus its fans, or for the assembly alongside motherboard heatsinks. An AIO also adds pump noise and more potential failure points than an air cooler. Arctic’s product and compatibility details and 2024 testing of the 360 and 280 mm models.

A later Tom’s Hardware retest assessed the Liquid Freezer III under a gaming-oriented workload differently from its initial review. That variation is a useful reminder that workload and methodology affect a cooler’s apparent value; it is not evidence that every system will reproduce either result. Tom’s Hardware’s retest.
Liquid Freezer III 280: balance radiator size and fit
Choose the 280 mm version when your case supports it and you want more radiator area than a 240 mm model without needing a 360 mm mount. A 280 is not automatically quieter or a better fit: confirm the case’s supported radiator dimensions and thickness, fan clearance, and interference with the motherboard or GPU before buying.
Liquid Freezer III 240: smaller AIO option
The 240 mm version is the more practical AIO size when the case cannot accommodate a larger radiator. It can suit a mainstream build or a constrained mounting layout, but a 240 mm AIO is not inherently better or quieter than a good dual-tower air cooler. A 120 mm AIO generally is not a meaningful performance upgrade over a quality air cooler unless the case layout specifically requires that format.
Arctic’s US product-range page displayed manufacturer MSRP signals of about $102.95 for the 240, $112.85 for the 280, and $117.80 for the 360 in August 2026.

Choose for CPU workload, not just the model name
Ryzen 5, Ryzen 7, and X3D gaming systems
A good air cooler is normally a sensible starting point. Ryzen X3D chips do not automatically need a 360 mm AIO because a peak temperature looks high: modern AMD boost behavior can push toward a thermal or power target. Judge cooling by sustained performance, noise, and temperature behavior together, rather than by one peak reading.
Ryzen 9 and other high-end AMD CPUs
For gaming and mixed workloads, a premium air cooler may be sufficient. A 280 or 360 mm AIO can add headroom during sustained all-core rendering or encoding, but no specific temperature can be promised without knowing the CPU, power settings, ambient conditions, and case airflow.
Core i5 and Core i7 systems
A dual-tower air cooler is a reasonable default for gaming and moderate workloads. How much cooling a Core i7 needs depends partly on motherboard settings: some boards allow more sustained power than Intel’s official limits, increasing cooler demand. Check firmware power settings instead of assuming the CPU’s name alone defines its heat output.
Recommended Free Tools
Core i9 and unrestricted all-core workloads
A premium dual-tower air cooler may handle gaming but can approach its limits during unrestricted all-core rendering, compilation, or simulation. A 280 or 360 mm AIO is more appropriate if the goal is sustained high power. Distinguish Intel’s official power limits from motherboard defaults such as multicore enhancement; enabling higher sustained power changes both heat and cooler requirements.

Check compatibility before buying
Socket and mounting hardware
- Confirm support for your exact socket: AM4, AM5, or LGA1700 are common targets for 2024 builds. Check older LGA1200 or LGA115x support only where the exact product lists it.
- Verify the exact cooler variant and whether its socket bracket is included. A used cooler may be missing the required hardware; some kits are sold separately.
- Check the mounting instructions for your motherboard. Some installations retain the motherboard’s stock backplate; do not remove or replace it unless the cooler instructions say to.
- Treat an aftermarket LGA1700 contact frame as a separate component, not as a universal requirement or a substitute for the cooler’s mounting hardware. Arctic markets a frame with the Liquid Freezer III ecosystem as intended to reduce mechanical stress and improve mounting consistency; that is the manufacturer’s claim. Results vary by CPU and motherboard, and installation responsibility or warranty implications may vary. Follow the frame maker’s instructions exactly. Arctic’s Liquid Freezer III details.
Air cooler height, RAM, and nearby components
- Compare the cooler’s published height with the case’s CPU-cooler limit; do not estimate from a photograph.
- Check memory height against the front fan and confirm whether the fan can be raised. Any adjustment adds to the cooler’s effective height.
- Look for interference with VRM heatsinks, the first PCIe slot, GPU backplate, and side panel. Motherboard layout matters as much as socket support.
- Do not assume universal RAM compatibility for a dual-tower model. Low-profile memory may make installation easier in crowded builds.
AIO radiator, GPU, and tubing clearance
- Check radiator length and thickness together with fan thickness. A nominal 360 mm support label does not guarantee space for every radiator assembly.
- For a top mount, check clearance above RAM and motherboard heatsinks. For a front mount, check how the radiator affects GPU length and case airflow.
- Confirm that tubing reaches without a sharp bend and that the pump/block can be installed in a suitable orientation.
- Consider the whole case layout. A front intake radiator may send warmer air into the case; a top exhaust radiator can remove CPU heat directly. Neither is universally best because GPU temperatures, airflow, and tubing position also matter.
- Verify the required pump, fan, RGB, or USB headers and any controller cables before installation.
Noise and benchmark results: what to compare
Maximum-speed tests show a cooler’s output at full fan speed, but not necessarily how it will sound in everyday use. Fixed-RPM tests hold fan speed constant, while noise-normalized tests compare cooling at the same measured acoustic output. The latter can be more useful when choosing between quiet builds, but review methods vary. Idle, gaming, and sustained full-load noise can also differ, and an AIO’s pump adds another sound source.
Do not compare decibel readings from separate reviews as if they were measured identically: microphone distance, room noise, calibration, test bench, and fan curves differ. The 2024 Gamers Nexus comparisons are useful for their stated noise-normalized methodology, not as a promise that another case and CPU will produce the same temperatures or sound level. Read the methodology and comparisons.
Installation and tuning
Installing an air cooler
- Confirm socket support, case height, RAM clearance, and the correct mounting hardware.
- Install the backplate, spacers, and mounting bars according to that cooler’s instructions.
- Apply thermal compound as directed by the manufacturer.
- Remove the center fan if needed to reach the heatsink screws; tighten evenly, alternating sides.
- Reinstall the fans and connect them to CPU_FAN or an appropriate PWM header.
- Check that the front fan does not press against the RAM and that the side panel closes without contact.
- Set a gradual fan curve in firmware or motherboard software, then check temperatures and noise under a representative workload.
Installing an AIO
- Confirm the radiator’s complete dimensions, supported mounting position, and clearance for fans, RAM, motherboard heatsinks, and GPU.
- Install the radiator and fans in the intended intake or exhaust direction, following the cooler and case instructions.
- Install the socket-specific pump/block hardware. Do not add an aftermarket contact frame unless you have separately verified compatibility and instructions.
- Route the tubes without sharp bends. Choose radiator and pump positioning based on the case layout and manufacturer’s guidance; there is no single orientation rule for every system.
- Connect pump power, radiator fans, and any RGB or USB controller leads to the specified headers.
- Set the pump header to the manufacturer-recommended mode in firmware, and confirm that the pump is detected and operating normally.
- Check CPU temperatures and listen for unexpected noise under load. If temperatures rise abnormally or the pump makes persistent unusual noise, stop the workload and consult the cooler maker’s troubleshooting and warranty guidance.
Maintenance and ownership
For an air cooler, keep dust from accumulating in the heatsink and fans; a fan can usually be replaced if it becomes noisy or stops. An AIO is generally a sealed product rather than a routine refill project. Pump failure, unusual pump noise, manufacturing defects, leaks, and coolant loss over time are possible, so check the specific vendor’s warranty and service process. Replacing an AIO is typically a larger job than swapping an air-cooler fan.
