Thermalright AXP-90 X53 Black Low Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
Evaluating Thermalright AXP 90 X53 Black low alternatives gives you options when planning your next compact system. The Thermalright AXP-90 X53 Black features a 53mm total height, four 6mm heat pipes, and a quiet 90mm PWM fan operating at 22.4 dBA or lower. Its all-metal mounting platform supports AM4, AM5, LGA115x, LGA1200, and LGA1851 sockets, while black nickel plating guards against corrosion. This design excels in compact enclosures where vertical clearance is limited.
You might still need a different cooler based on your chassis dimensions and hardware goals. Ultra-small ITX cases may require lower heights, such as 47mm or 36mm designs. Conversely, cases with more vertical space can take 120mm single-tower or dual-tower models offering six heat pipes, ARGB lighting, or digital displays. The 6 alternatives in this guide were chosen because their specs overlap with the original through shared socket compatibility, compact footprints, and multi-heatpipe cooling layouts.
Our top pick: Thermalright 53mm Low-Profile CPU Cooler.
AXP-90 X53 Alternatives Compared
Thermalright Assassin X 120R Digital ARGB Air Cooler
The Assassin X 120R Digital ARGB switches from a 53mm low-profile form factor to a 151mm single-tower cooler. It adds integrated addressable RGB lighting, real-time digital monitoring, and a fast 2,000 RPM fan. It also adds native Intel LGA 1700 socket support alongside LGA 1851, LGA 1200, and AMD AM4 and AM5. You give up the tight 53mm clearance of the AXP-90 X53, so it will not fit small-form-factor enclosures. Its four direct-touch heat pipes match the original count while shifting to vertical tower orientation. You should choose this cooler if your chassis supports a 151mm tower and you want integrated digital readouts with ARGB effects.
Thermalright 47mm Low-Profile CPU Cooler
The Thermalright 47mm model lowers the overall profile from 53mm down to 47mm, saving you 6mm of vertical space. It retains the same four 6mm heat pipe layout, black finish, and quiet 22.4 dBA noise threshold as the AXP-90 X53. You give up 6mm of heatsink fin depth, which reduces total surface area. It supports the same primary socket platforms, including AM4, AM5, LGA 1851, and LGA 1200. At 1.1 pounds, it is slightly heavier than the 1-pound X53. You should choose this alternative if your small-form-factor or ITX case strictly enforces a 48mm or 50mm maximum cooler clearance where the 53mm unit cannot fit.
Thermalright AXP90 36mm Low-Profile Cooler
The AXP90 36mm model cuts cooler clearance down to just 36mm, shedding 17mm compared to the 53mm AXP-90 X53. It maintains a four-heat-pipe configuration and covers identical socket options, including Intel LGA 1851, LGA 1200, LGA 115x, and AMD AM4 and AM5. Weight drops to 15.8 ounces compared to the 1-pound original. In exchange for the ultra-compact height, you sacrifice substantial heatsink volume and fin area. That trade-off makes it less capable of sustained heat absorption compared to the taller 53mm stack. Pick this model if you are assembling an ultra-slim ITX enclosure where 53mm is too tall and vertical clearance is capped under 40mm.
Thermalright Assassin X120 120mm Air Cooler
The Assassin X120 moves away from the low-profile design entirely, standing 148mm tall as an aluminum single-tower cooler. It upgrades from the original 90mm fan to a standard 120mm fan for broader airflow distribution across its fin array. It maintains four heat pipes and shares socket support for AM4, AM5, LGA 1851, and LGA 1200. By shifting to a tower format, you give up all small-form-factor compatibility, requiring nearly three times the vertical headroom of the 53mm AXP-90. It also weighs more at 1.42 pounds. Pick this option if your PC case has at least 148mm of CPU cooler clearance and you prefer standard 120mm tower cooling.
Thermalright Peerless Assassin 120 Dual-Tower Cooler
The Peerless Assassin 120 is a full-sized dual-tower heatsink equipped with six heat pipes, whereas the AXP-90 X53 relies on four. It features two 120mm fans instead of a single 90mm fan, providing substantially larger fin surface area and airflow paths. You trade away all compact form-factor clearance, as this model stands 157mm tall compared to the original 53mm. Socket support covers AM4, LGA 1851, LGA 1200, and LGA 115x, though AM5 is omitted from its attributes. You should choose this cooler if your enclosure accommodates standard tower coolers up to 157mm and you want six heat pipes with dual 120mm fans instead of a low-profile heatsink.
Thermalright Assassin X 120 RGB CPU Cooler
The Assassin X 120 RGB features a 148mm single-tower build with an RGB-lit 120mm fan pushing up to 66.17 CFM of airflow. In contrast, the AXP-90 X53 uses a compact 90mm fan without illumination. This model also includes LGA 1700 support alongside LGA 1851, LGA 1200, LGA 115x, and AMD AM4 and AM5. You lose the 53mm clearance of the low-profile unit, making this cooler unsuitable for slim SFF cases. It retains four heat pipes like the original, but arranges them in a tall tower. Choose this cooler if you have a mid-sized case with 148mm clearance and prioritize RGB lighting and 66.17 CFM airflow.

Frequently asked questions
Which Thermalright low-profile alternative offers the lowest clearance height?
The Thermalright AXP90 36mm Low-Profile Cooler provides the shortest clearance at 36mm tall. This model fits ultra-compact ITX enclosures where space prevents installing 53mm or 47mm units. It uses four heat pipes and supports AM4, AM5, LGA 1851, LGA 1200, LGA 1150, and LGA 1151 sockets. Its overall weight measures 15.8 ounces.
How does the Thermalright AXP90 X47 compare in size to the X53?
The Thermalright 47mm Low-Profile CPU Cooler reduces vertical height by 6mm compared to the 53mm model. Designed for ITX systems, it stands 47mm tall and operates at 22.4 dBA. The heatsink assembly features four 6mm heat pipes, weighs 1.1 pounds, and adds AM5 socket compatibility alongside AM4, LGA 1851, LGA 1200, LGA 1150, and LGA 1151.
Which alternative provides the highest heat pipe count on this list?
The Thermalright Peerless Assassin 120 Dual-Tower Cooler provides the highest count with six heat pipes. Unlike low-profile alternatives that rely on four pipes, this dual-tower aluminum model utilizes twin 120mm fans for heat dissipation. It requires a chassis with at least 157mm of clearance and fits AM4, LGA 1851, LGA 1200, LGA 1150, and LGA 1151 motherboards.
Which alternatives support the Intel LGA 1700 socket?
The Assassin X 120R Digital ARGB and Assassin X 120 RGB coolers support the LGA 1700 socket. While low-profile models like the AXP-90 series omit LGA 1700 in their listed specs, these 120mm tower designs accommodate it. Both also support AMD AM4 and AM5 alongside Intel LGA 1851, LGA 1200, LGA 1150, and LGA 1151.
What is the height difference between the low-profile models and standard tower alternatives?
Low-profile models range from 36mm to 53mm tall, whereas tower alternatives measure between 148mm and 157mm. The AXP90 X36, X47, and X53 suit compact ITX cases. In contrast, standard tower coolers like the Assassin X120 Refined SE at 148mm or Peerless Assassin 120 at 157mm require mid-sized or full-sized chassis with substantially deeper internal clearance.
What airflow rating does the Thermalright Assassin X 120 RGB provide?
The Thermalright Assassin X 120 RGB delivers an airflow rating of 66.17 CFM. This single-tower cooler stands 148mm high, uses four heat pipes, and includes integrated RGB lighting with shared-power illumination. You can install it on AM4, AM5, LGA 1700, LGA 1851, LGA 1200, LGA 1150, and LGA 1151 platforms if your case supports standard tower heights.
Which alternatives feature AM5 socket compatibility out of the box?
The Thermalright 47mm, AXP90 36mm, Assassin X 120R Digital ARGB, Assassin X120 Refined SE, and Assassin X 120 RGB list AM5 compatibility. The base AXP-90 X53 and Peerless Assassin 120 specify AM4 without AM5 listed in their socket attributes. If your build uses an AM5 processor, verify these socket specifications before selecting your cooler.
