The DeepCool AK620 CPU Air Cooler is the straightforward choice for builders who want powerful air cooling without a pump or radiator, while a 360mm AIO suits compatible cases and users who prefer liquid cooling. For Black Friday 2026, compare the complete package: cooler dimensions, fan count, socket support, noise features and warranty, not just the cooler type.
We researched and compared specs, reviews and owner feedback across seven air and liquid coolers. My pick for most people is the DeepCool AK620 CPU Air Cooler when case clearance allows; an AIO makes more sense when a build has room for its radiator and the buyer values a cleaner CPU socket area. The recommendations below explain who each product fits, what its key numbers mean and which compromises matter.
How We Picked
- Compared published specifications, including cooler height, radiator size, fan diameter and heatpipe count.
- Reviewed socket support and installation requirements so buyers can check compatibility before ordering.
- Considered reported owner feedback about setup, noise characteristics, software features and long-term upkeep.
- Compared the practical trade-offs between air towers and AIOs, including case fit, pump presence and radiator placement.
- Selected products across budget, quiet-focused, premium and liquid-cooling needs rather than treating one cooler type as right for every build.

Is the DeepCool AK620 better than an AIO cooler?
The DeepCool AK620 CPU Air Cooler is the better fit for a buyer who values a pump-free setup, while a 360mm AIO such as the ARCTIC Liquid Freezer III 360 A-RGB CPU Water Cooler suits cases built for radiator mounting. The AK620 uses six heatpipes, two 120mm fans and a 160mm tower. Those details make it a substantial cooler, but also mean that case height and memory clearance matter.
AIO cooling moves heat through a pump, tubing and radiator, opening up the area around the CPU socket and supporting a different case layout. The trade-off is more installation planning and a pump as an additional part. Skip it if your case lacks radiator space or you prefer fewer cooling components. Choose the AK620 when a compatible tower fits and straightforward upkeep matters more than radiator placement or pump-head features.
Which cooler is the best value for Black Friday 2026?
The Thermalright Peerless Assassin 120 SE CPU Air Cooler is the value-focused pick, while the DeepCool AK620 CPU Air Cooler is the balanced choice for buyers who want a polished dual-tower air setup. The Peerless Assassin uses six heatpipes, two 120mm fans and a 155mm height. The AK620 also has six heatpipes and two 120mm fans, with a 160mm height.
Value comes down to fit and the features a buyer will use, not just a listed promotion. Compare included fans, socket brackets, warranty terms and cooler dimensions alongside the retailer’s current listing. A 360mm AIO brings a radiator and three fans, which suits some builds but adds parts and installation steps. For many standard desktop builds, a compatible dual-tower air cooler offers a useful balance of cooling hardware and simplicity.
When should you choose a 360mm AIO over an air cooler?
The ARCTIC Liquid Freezer III 360 A-RGB CPU Water Cooler is a fitting AIO choice when a case supports a 360mm radiator and the build benefits from a clear CPU socket area. The NZXT Kraken 360 RGB CPU Liquid Cooler adds a 1.54-inch LCD, while the Corsair Nautilus 360 RS CPU Liquid Cooler keeps its feature set simpler with three RS120 fans.
Radiator location is central to the decision: check top and front mounting support, radiator thickness, fan clearance and tubing reach. An AIO also places a pump in the system, so buyers should consider warranty and installation preferences. A 360mm radiator is not automatically the right answer for every processor or case. A well-fitting air cooler remains a compelling choice when fewer parts, accessible maintenance and a compact cooling path are priorities.
Will the DeepCool AK620 fit my PC case and RAM?
The DeepCool AK620 CPU Air Cooler needs at least 160mm of CPU-cooler clearance, and its dual-tower shape calls for a check of memory height and motherboard layout. The Thermalright Peerless Assassin 120 SE CPU Air Cooler is 155mm tall, but its fan position and the memory modules still affect fit. Check the case maker’s maximum cooler height rather than relying on a general case size label.
Before ordering, compare the cooler’s published dimensions with the case, RAM and motherboard manuals. Also confirm CPU socket support for the exact cooler revision and included mounting hardware. A front fan that sits above tall memory can add to the total cooler height. For an AIO, verify radiator and fan thickness, not only the advertised radiator length. A few minutes with these measurements prevents a return caused by a clearance conflict.
Are air coolers easier to maintain than AIO coolers?
The DeepCool AK620 CPU Air Cooler is the simpler long-term choice for buyers who want to avoid a pump, while the DeepCool LS720S ZERO DARK CPU Liquid Cooler provides the radiator-based design some builders prefer. Air coolers use fans and a heatsink; AIOs add a pump and sealed tubing to the cooling system.
Both cooler types need dust cleaning and reliable fan operation. An air tower generally has fewer cooling components to connect, and fan replacement is straightforward when needed. AIO installation requires radiator placement, tubing routing and pump connections, with the exact process varying by case and motherboard. Review the manufacturer’s warranty and socket instructions for either option. Pick by fit and comfort with the setup, rather than assuming one category requires no maintenance.
Buying Guide
Measure the case before choosing a tower
The DeepCool AK620 CPU Air Cooler needs 160mm of height clearance, and the Noctua NH-D15 chromax.black CPU Cooler needs 165mm. Check the case specification and memory height before selecting either tower; a listed cooler-height limit is more useful than the case’s overall dimensions.
Confirm radiator support for an AIO
The ARCTIC Liquid Freezer III 360 A-RGB CPU Water Cooler needs a compatible 360mm radiator position. Check radiator-and-fan thickness, motherboard heatsink clearance and tubing reach. Front and top mounts create different airflow layouts, so confirm the mounting plan before choosing a cooler.
Match the cooler to the CPU socket
The Thermalright Peerless Assassin 120 SE CPU Air Cooler and all AIOs need the correct mounting hardware for the processor socket. Check the exact product revision, included brackets and manufacturer compatibility list. Confirm that the motherboard and case leave room for installation.
Compare the full feature set
The NZXT Kraken 360 RGB CPU Liquid Cooler adds a 1.54-inch LCD, while the Corsair Nautilus 360 RS CPU Liquid Cooler uses three RS120 fans without a pump display. Compare included fans, lighting, controls, warranty and software needs to judge overall value.
Choose the cooling type you want to maintain
The DeepCool AK620 CPU Air Cooler has no pump, while the DeepCool LS720S ZERO DARK CPU Liquid Cooler uses a pump, tubing and radiator. Both need dust care and working fans. Pick the layout and installation process that suits your case and comfort level.
