6 Best Alternatives to the Akasa ALUCIA H6LS M2 (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are building a compact PC, searching for akasa alucia h6ls m2 alternatives can help you balance dimensions and thermal performance. The Akasa ALUCIA H6LS M2 fits tight spaces with its 67.2mm low-profile height and slim 15mm fan. It dissipates up to 150W TDP using six copper heat pipes and a nickel-plated copper base, while maintaining clearance for your memory modules on Intel LGA1851, LGA1700, and AMD AM5 motherboards.
However, your build may allow for a different design, feature set, or socket layout. If your case accommodates taller coolers, you might prefer a dual-tower design, ARGB lighting, an all-white finish, or higher thermal capacity up to 260W TDP. You may also need mounting hardware for older platforms like AMD AM4, Intel LGA 1200, or LGA 1150. The 6 options in this 2026 guide were chosen because their specifications overlap with the original, sharing 120mm fan configurations, six copper heat pipe layouts, and modern socket support.
Our top pick: Akasa ALUCIA H6LS M2 Low-Profile Cooler.
How Each Alternative Compares
Cooler Master Hyper 620S Dual Tower Cooler
The Cooler Master Hyper 620S moves from a low-profile layout to a dual-tower design standing 154.9mm tall. While both units utilize six copper heat pipes and a 120mm fan, the Hyper 620S adds ARGB lighting and broadens socket support to include AM4 and LGA 1200. In exchange, you lose the compact 67.2mm clearance of the Akasa ALUCIA H6LS M2, making the Cooler Master unusable in tight Mini-ITX cases. It also increases weight to 2.45 pounds compared to the Akasa cooler's 1.76 pounds. Choose the Hyper 620S if you build in a mid-tower case, want dual-tower cooling and lighting, or use AM4 or LGA 1200 platforms.
Jonsbo 120mm Dual-Tower CPU Air Cooler
The Jonsbo Dual-Tower cooler targets higher thermal loads with a 260W TDP rating, significantly exceeding the Akasa model's 150W TDP rating. Both units feature six copper heat pipes and 120mm fan sizing, but Jonsbo includes integrated ARGB lighting and compatibility for AM4 and LGA 1200 sockets. However, you trade away the low-profile 67.2mm height of the Akasa ALUCIA H6LS M2. At 159mm tall, this dual-tower cooler will not fit inside slim Mini-ITX enclosures. It also omits listed LGA 1700 support. You should pick the Jonsbo cooler if your desktop chassis accommodates a 159mm tower and you need maximum cooling capacity for a high-wattage processor.
Raijintek Themis II 5-Heatpipe 120mm Cooler
The Raijintek Themis II adopts a standard vertical tower format measuring 6.1 inches high. At 1.23 pounds, it is lighter than the 1.76-pound Akasa cooler. However, it scales down to five copper heat pipes compared to the six found on the Akasa ALUCIA H6LS M2. It also restricts socket compatibility to LGA 1700, dropping the LGA 1851 and AM5 options provided by the Akasa model. You sacrifice low-profile clearance, as its 6.1-inch stature prevents installation in compact small form factor enclosures. Choose the Themis II if you build inside a standard tower case with an Intel LGA 1700 motherboard and prefer a lighter single-tower configuration.
Raijintek ELEOS 12 EVO RBW 120mm Cooler
The Raijintek ELEOS 12 EVO RBW introduces onboard RGB illumination and weighs 1.34 pounds, making it lighter than the 1.76-pound Akasa unit. Both coolers feature six copper heat pipes and utilize a 120mm fan. However, the ELEOS stands 6.46 inches tall, abandoning the 2.65-inch (67.2mm) low-profile footprint that allows the Akasa ALUCIA H6LS M2 to slide into Mini-ITX cases. In addition, its documented socket list focuses on LGA 1700, whereas the Akasa explicitly details LGA 1851, LGA 1700, and AM5 compatibility. Pick the ELEOS 12 EVO RBW if your enclosure has standard tower clearance and you want RGB lighting with six direct-contact copper heat pipes.
Cooler Master Hyper 622 Halo White Dual Tower Cooler
The Cooler Master Hyper 622 Halo White features a dual-tower structure, an all-white finish, and dual-loop ARGB lighting. Like the Akasa ALUCIA H6LS M2, it incorporates six copper heat pipes, but it extends socket support to include AM4 and LGA 1200 alongside AM5 and LGA 1851. By choosing this cooler, you give up low-profile packaging. At 157mm in height and weighing 2.78 pounds, it requires significantly more enclosure space and adds more weight than Akasa's 67.2mm, 1.76-pound design. It also leaves out LGA 1700 support. Select the Hyper 622 Halo White if you are building an all-white mid-tower system with ample vertical clearance.
Thermalright Peerless Assassin 120 Mini Black
The Thermalright Peerless Assassin 120 Mini Black delivers broad motherboard compatibility, adding support for LGA 1150, LGA 1151, LGA 1200, and AM4. Both coolers use six copper heat pipes and a 120mm fan design. At 135mm tall, the Peerless Assassin Mini is more compact than standard 155mm towers, but it is roughly twice the height of the 67.2mm Akasa ALUCIA H6LS M2. You give up the Akasa model's slim 15mm fan and ultra-low profile, which allows installation in tight Mini-ITX cases. You should choose the Peerless Assassin 120 Mini if you run legacy Intel sockets like LGA 1150 or want dual-tower cooling within 135mm clearance.

Frequently asked questions
Which alternative to the Akasa ALUCIA H6LS M2 offers the highest cooling capacity?
The Jonsbo 120mm Dual-Tower CPU Air Cooler offers the highest cooling capacity with its 260W thermal rating. You get dual-tower fin stacks, six copper heat pipes, and integrated ARGB lighting. Keep in mind that this cooler measures 159mm in height, requiring a standard desktop case rather than a compact enclosure. It supports modern AMD and Intel sockets including AM4, AM5, LGA 1200, and LGA 1851.
What is the most compact tower alternative if your case cannot fit a standard 160mm cooler?
The Thermalright Peerless Assassin 120 Mini Black is your most compact tower option on this list. It stands at a reduced height profile of 135 mm while retaining six heat pipes and a 120mm fan. This allows you to fit tower cooling into chassis that lack clearance for traditional 155mm or 160mm units. It also supports older platforms such as LGA 1150 and LGA 1151.
Can you fit the Raijintek Themis II into a low-profile case?
You cannot install the Raijintek Themis II inside a slim low-profile case. It features a traditional single-tower layout with a height of 6.1 inches, requiring a standard tower enclosure. The design incorporates five direct-contact copper heat pipes and a 120mm PWM fan. If you select this model, verify your chassis has at least 6.1 inches of vertical CPU clearance above the motherboard.
Which alternative should you choose for an all-white computer build?
The Cooler Master Hyper 622 Halo White Dual Tower Cooler is the dedicated option for white-themed builds. It features an all-white finish across the heatsink structure along with dual-loop ARGB lighting. Mechanically, it uses six copper heat pipes across two fin towers and stands 157mm tall. You must ensure your computer chassis accommodates standard tower dimensions, as it does not fit slim form factor setups.
Which alternatives support legacy Intel sockets like LGA 1150 and LGA 1151?
The Thermalright Peerless Assassin 120 Mini Black provides documented compatibility for LGA 1150 and LGA 1151 sockets. Many modern alternatives restrict their Intel brackets to LGA 1200, LGA 1700, or LGA 1851. If you are servicing or upgrading an older system based on fourth-generation to ninth-generation Intel desktop processors, this black-finish cooler delivers six copper heat pipes and a 120mm fan without needing custom mounting adapters.
How does the Raijintek ELEOS 12 EVO RBW compare in physical dimensions to low-profile coolers?
The Raijintek ELEOS 12 EVO RBW stands 6.46 inches tall, making it substantially taller than horizontal low-profile designs. It has a depth of 2.95 inches and a width of 5 inches, carrying six direct-contact copper heat pipes and addressable RGB lighting. You will need a mid-tower or full-tower enclosure to fit its vertical height, meaning it cannot replace low-profile coolers in slim or compact enclosures.
Do these cooler alternatives include cooling fans in the box?
Yes, all 6 cooling alternatives in this guide include a 120mm fan in the package. Single-tower options like the Raijintek Themis II and Raijintek ELEOS 12 EVO RBW use a single 120mm fan configuration. Dual-tower options like the Jonsbo model utilize dual-fan airflow to push air across twin heatsinks. You do not need to supply a separate cooling fan for any of these listed units.
