THERMALRLGHT CPU Cooler Lineup Overview
THERMALRLGHT offers distinct coolers for different build types. The Assassin X 120R Digital ARGB fits standard desktops with its 151mm height and digital display. It supports AM5 and LGA 1851 sockets. This model suits users who need broad compatibility and modern features in a 120mm form factor. You get ARGB lighting and fan support in a black finish.
For small form factor builds, THERMALRLGHT provides low-profile options. The 47mm Low Profile Black ITX Cooler prioritizes case fit over maximum thermal performance. It stands just 1.85 inches tall. The AXP120-X67 Black ARGB Low Profile adds six heat pipes for better cooling in compact spaces. It reaches 2.64 inches in height. Both support AM4 and AM5 sockets. These units help you fit cooling into tight ITX cases.
Who THERMALRLGHT Coolers Suit
THERMALRLGHT’s current lineup spans from ultra-low profile to standard 120mm towers. The AXP90 X47 offers a mere 47mm height for tight ITX cases. The AXP120-X67 adds six heat pipes and ARGB lighting while staying under 67mm. The Assassin X 120R Digital reaches 151mm, featuring a unique digital display for larger desktops. All models include fans. You will not find passive coolers or RGB fans without ARGB here. The range covers low height and standard depth, but lacks dual-tower designs or non-ARGB lighting options in this selection.
How to choose the right THERMALRLGHT cooler
-
Check socket compatibility first
You must verify that the cooler supports your specific CPU socket. The Assassin X 120R Digital ARGB supports AM5 and LGA 1851, making it suitable for modern platforms. The low-profile AXP90 X47 also covers AM4 and AM5. Always match the cooler's listed sockets to your motherboard to ensure physical mounting holes align. Mismatched sockets prevent installation. This step eliminates incompatible options before you consider height or airflow.
-
Measure case height limits
Your computer case has a maximum cooler height. The Assassin X 120R Digital ARGB stands 5.94 inches tall. If your case supports 151mm, this unit fits. For smaller ITX cases, you need a low-profile design. The AXP90 X47 is only 1.85 inches high. The AXP120-X67 is 2.64 inches tall. Measure your case clearance carefully. Exceeding the limit prevents the side panel from closing. This spec dictates which physical form factor you can actually use.
-
Select the right system type
Your build type determines the cooler category. Standard desktops can use the Assassin X 120R Digital ARGB. It offers standard 120mm airflow. Compact ITX builds require low-profile units. The AXP90 X47 is designed for tight spaces. The AXP120-X67 also targets small form factors. Choosing the wrong system type leads to clearance issues or poor performance. Match your case size to the cooler's intended use. This ensures the cooler fits both the case and the airflow requirements.
-
Count the heat pipes
Heat pipes transfer heat from the CPU to the fins. The AXP120-X67 includes six heat pipes. This increases thermal capacity in a small volume. The Assassin X 120R Digital ARGB does not list a pipe count in the provided data. More pipes generally help dissipate heat faster. However, fan speed and fin density also matter. Check this spec if you plan to overclock. It indicates the cooler's ability to handle sustained thermal loads without relying solely on fan RPM.
-
Decide on lighting needs
ARGB lighting adds visual customization to your build. The Assassin X 120R Digital ARGB and AXP120-X67 both include ARGB features. The AXP90 X47 does not list lighting. If you want synchronized effects, ensure your motherboard supports ARGB headers. Lighting does not improve cooling performance. It is purely aesthetic. Choose a model with lighting only if it fits your visual preferences. Otherwise, a non-ARGB model may offer better value or simpler installation.
