Looking Beyond the Thermalright AXP90 X47 Black Low Profile CPU Cooler? 6 Alternatives Worth a Look
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The thermalright axp90 x47 black low profile CPU cooler alternatives list helps you find the right fit for your small form factor build. This cooler stands out with its 47mm height and four 6mm heat pipes. It supports modern sockets like AM5 and LGA1700 while keeping a slim 92mm fan profile. You get a compact solution that fits tight ITX cases without sacrificing socket compatibility.
However, your case might have different clearance limits. You may need a 36mm height for ultra-slim enclosures or a 53mm tower for better heat dissipation. Some builders prioritize pure copper construction over aluminum fins. Others might need specific socket support that the original does not cover. We selected these alternatives because their specifications overlap with the original. This ensures you can compare height, socket compatibility, and heat pipe counts directly. Each option addresses a specific constraint you might face in your build.
Our top pick: Thermalright 47mm Low-Profile CPU Cooler.
Comparing Alternative Low-Profile Coolers
Thermalright AXP90 36mm Low-Profile Cooler
Thermalright AXP90 36mm Low-Profile Cooler reduces total height from 47mm down to 36mm, saving 11mm of vertical clearance inside tight enclosures. It weighs 15.8 ounces compared to the original 1.1 pounds while retaining four 6mm heat pipes and a slim 92mm PWM fan. Socket compatibility matches the original across AMD AM4, AM5, and Intel LGA 1851, LGA 1200, and LGA 115x. You give up the larger heatsink mass and fin surface area of the 47mm design. Pick this alternative if your small-form-factor build has an ultra-shallow chassis where cooler height is restricted to under 40mm.
Thermalright AXP90-X47 Black Low-Profile Cooler matches the original 47mm total height, four heat pipes, and 92mm slim PWM fan configuration. It weighs exactly 1 pound, making it slightly lighter than the 1.1-pound original model. In exchange for the minor weight reduction, you give up official support for Intel LGA 1851 sockets found on the primary pick. Socket support remains limited to Intel LGA 1200, LGA 1150, and LGA 1151, alongside AMD AM4 and AM5. You should pick this alternative if you need the identical 47mm low-profile layout for an existing AM4, AM5, or older Intel system without needing LGA 1851 compatibility.
Thermalright AXP90 X36 Black Low Profile Cooler
Thermalright AXP90 X36 Black Low Profile Cooler lowers total height to 36mm, saving 11mm of clearance compared to the 47mm original. It weighs 1 pound, uses four heat pipes, and is specified for CPUs up to 95W. The tradeoff comes in reduced heatsink volume and the absence of Intel LGA 1851 socket compatibility, supporting only LGA 1200, LGA 1150, LGA 1151, AM4, and AM5. You give up the extra vertical fin area and newer socket coverage. Choose this model if your compact ITX chassis strictly demands a cooler height under 40mm and your CPU stays within the 95W rating.
Thermalright 53mm Full Copper ITX Cooler
Thermalright 53mm Full Copper ITX Cooler increases height to 53mm, adding 6mm over the 47mm original design. In exchange for the taller profile, it provides an all-copper build and expands compatibility by including Intel LGA 1700 support alongside LGA 1851, LGA 1200, LGA 115x, AM4, and AM5. You give up the lower 47mm vertical profile, so it will not fit chassis that have sub-50mm clearance limits. Pick this full-copper alternative if your mini-ITX enclosure offers at least 53mm of vertical CPU cooler clearance and you are building on the Intel LGA 1700 platform.
Thermalright Peerless Assassin 120 Mini Black steps away from ultra-low-profile dimensions to stand 135mm tall. It upgrades your thermal hardware with six 6mm heat pipes and a larger 120mm fan, compared to the four heat pipes and 92mm fan on the 47mm original. Socket support remains identical, covering AM4, AM5, LGA 1851, LGA 1200, and LGA 115x. You give up the compact 47mm height, which prevents this unit from fitting into slim mini-ITX cases. Choose this cooler instead if your chassis allows at least 135mm of clearance and you want two additional heat pipes paired with a full 120mm fan.
Thermalright AXP90 53mm Low Profile Cooler stands 53mm tall, measuring 6mm higher than the 47mm original. It features four heat pipes and a 92mm fan capable of running up to 2700 RPM. What you give up is the 47mm low profile along with LGA 1851 mounting, as supported sockets cover Intel LGA 1200, LGA 1150, LGA 1151, AMD AM4, and AMD AM5. You also lose compatibility with cases that cannot clear components over 50mm. You should pick this alternative if your small-form-factor case provides at least 53mm of vertical clearance and you want a 92mm fan operating up to 2700 RPM.
