How to Choose the Right Thermalright Cooler
-
Count The Heat Pipes
You should check how many heat pipes route through the cooling fins. More heat pipes provide more paths to transfer thermal energy away from the processor base. Compact models typically include either four or six heat pipes. The Thermalright AXP120 67mm Low-Profile Cooler features six heat pipes inside its sub-70mm design. If your chassis allows enough vertical space for a larger heatsink assembly, choosing a six-pipe configuration delivers a more capable thermal structure for your desktop processor.
-
Measure Motherboard Footprint
You must evaluate cooler length and width to avoid crowding adjacent components. Small enclosures leave minimal margin around the processor socket where heatsinks can bump memory modules or rear input-output covers. The Thermalright AXP90 36mm Low-Profile Cooler maintains a compact footprint measuring 3.74 inches wide and 3.72 inches long. This narrow square shape keeps the heatsink within tight keep-out zones on compact motherboards. Always check your board layout against the cooler dimensions before finalizing your hardware setup.
-
Check ARGB Header Requirements
You should review lighting specifications if your build features an illuminated theme. Certain heatsink models integrate addressable lighting right into the fan frame. The Thermalright AXP120-X67 White ARGB Cooler includes built-in ARGB lighting to illuminate your system interior. Choosing an illuminated cooler requires an accessible ARGB header on your motherboard or an external control hub. If your motherboard lacks lighting headers, or if you prefer a blackout aesthetic, pick a standard non-illuminated model to avoid dealing with extra cables.
-
Select Matching Heatsink Color
You can match cooler finish to your enclosure and internal hardware styling. Manufacturer models come in varied color treatments like coated black, clean white, or standard metal finishes. A white finish fits bright themed rigs, while a black coating blends into darker cases and hides shadow lines. For example, if you build a monochrome system, choosing a black heatsink helps unify the appearance of your components. Always check the color specification in the product listing to ensure the cooler matches your build aesthetic.
-
Account For Cooler Weight
You should consider cooler mass when choosing hardware for portable or frequently moved systems. Low-profile heatsinks vary notably in weight depending on their dimensions and materials. Lighter coolers around 15.8 ounces put less physical stress on the motherboard socket during transport. Larger low-profile options weigh up to 1.34 pounds due to thicker fin stacks and wider fans. If you plan to move your desktop chassis to events or between desks, verify that your motherboard mounting points securely support the listed weight specification.
Frequently asked questions
Does the Thermalright AXP90 support Intel LGA 1851 motherboards?
Yes, the Thermalright AXP90 supports the Intel LGA 1851 socket directly out of the box. Its mounting hardware matches this newer interface alongside older platforms like LGA 1200, LGA 1151, and LGA 1150. You also get compatibility with AMD AM4 and AM5 systems. This wide bracket coverage allows you to deploy the 36mm heatsink across several processor generations without buying separate conversion kits.
Which low-profile Thermalright cooler includes ARGB lighting?
The Thermalright AXP120-X67 White ARGB Cooler features integrated ARGB illumination. This model pairs addressable lighting with an all-white heatsink and fan assembly. It measures 2.64 inches tall, utilizing six heat pipes and a slim 120mm fan for heat dissipation. If you want coordinated chassis illumination inside a compact setup, this cooler provides lighting controls while maintaining a low overall profile.
Can you fit the Thermalright AXP120-X67 on an Intel LGA 1700 motherboard?
Yes, the Thermalright AXP120-X67 models support Intel LGA 1700 motherboards. Both the standard low-profile version and the White ARGB model include mounting hardware for the LGA 1700 socket. They also support LGA 1200, LGA 1150, LGA 1151, and AMD AM4. You can mount these 67mm units onto modern Intel desktop boards provided your chassis offers adequate vertical clearance for the heatsink.
Does the Thermalright AXP120-X67 support the AMD AM5 socket?
No, the published specifications for the Thermalright AXP120-X67 do not list AMD AM5 compatibility. The documentation specifies support for AMD AM4 alongside multiple Intel sockets like LGA 1700 and LGA 1200. If you require an AM5 cooler in this selection, the Thermalright AXP90 lists explicit AM5 support out of the box. Always verify manufacturer socket brackets before pairing a heatsink with an AM5 processor.
What are the physical dimensions of the Thermalright AXP90 cooler?
The Thermalright AXP90 measures 3.74 inches wide, 3.72 inches long, and 1.42 inches tall. This corresponds to an overall heatsink height of roughly 36mm, designed specifically for ITX builds. It weighs 15.8 ounces with its bundled cooling fan. These compact footprint dimensions allow the heatsink to fit inside ultra-small enclosures where horizontal clearance around motherboard components and low vertical ceiling room are critical limitations.
How much heavier is the Thermalright AXP120 compared to the AXP90?
The Thermalright AXP120 weighs 1.34 pounds, making it about 5.6 ounces heavier than the 15.8-ounce AXP90. This added mass comes from its larger fin array, 67mm overall height, and wider footprint measuring 4.72 by 4.86 inches. The AXP120 also integrates six heat pipes rather than four. A heavier heatsink provides more metal surface area for heat distribution if your motherboard supports the physical bulk.
What fan size comes installed on the Thermalright AXP120 coolers?
The Thermalright AXP120 coolers use a 120mm fan. Both the standard AXP120 and the White ARGB edition utilize this larger fan diameter across their 4.72-inch width and 4.86-inch length heatsinks. A 120mm fan moves air across a wider surface area than sub-90mm fans. This allows the cooler to maintain steady airflow across all six heat pipes while keeping the total height under 70mm.
