How to Choose Your Thermalright Cooler
-
Count the Heat Pipes
Check the heat pipe specification to gauge thermal transfer capability. Thermalright designs in this group offer four, five, or six heat pipes. Four heat pipes suit standard desktop processors with basic thermal demands. Five or six heat pipes provide more surface contact to move thermal energy away from the CPU core quickly. For higher thermal loads up to 235W, a five-pipe unit like the Thermalright Assassin King 120 SE CPU Cooler provides extra thermal capacity. Verify your processor thermal output against the pipe count before buying.
-
Evaluate Fan Diameter
Examine the fan size specified on the cooler. Models feature either 92mm or 120mm fans. A 92mm fan fits narrower chassis layouts and clears neighboring motherboard components in tight spaces. A 120mm fan moves a greater volume of air across the heatsink fins at lower rotational speeds. For example, the Thermalright Assassin King 120 SE ARGB delivers up to 66.17 CFM of airflow while keeping sound output below 25.6 dB(A). Select a 120mm fan for maximum airflow, or choose 92mm when horizontal space around the socket is restricted.
-
Verify Specific Socket Support
Check the supported socket list against your motherboard model. While many coolers span both AMD and Intel sockets, support varies across specific revisions. Sockets listed across these models include AMD AM4 and AM5 alongside Intel LGA 1150, LGA 1151, LGA 1200, LGA 1700, and LGA 1851. Certain models, such as the Thermalright 47mm Low-Profile CPU Cooler, explicitly list AM5 and LGA 1851 compatibility. Confirm that your exact platform appears in the cooler socket specifications before purchasing so the included mounting hardware fits your motherboard without requiring separate mounting adapters.
-
Choose Lighting Preferences
Decide whether your system build needs integrated lighting. The product line includes standard non-illuminated coolers and units equipped with addressable RGB fans. Non-RGB models keep your internal chassis appearance clean, dark, and simple. In contrast, models like the Thermalright Assassin X 120 ARGB Cooler provide customizable illumination through standard 3-pin ARGB headers. If you use a solid side panel without a window, a non-RGB option avoids unneeded illumination cables. If you display your interior hardware through a glass side panel, choose an ARGB model to coordinate colors with your other components.
-
Select Heatsink Color
Match the heatsink color to your build theme. Thermalright provides coolers in standard silver aluminum, coated black, and all-white finishes. Silver heatsinks match industrial or unthemed builds and pair with standard motherboards. All-black designs blend into dark cases and minimize visual distraction. For themed white PC enclosures, options such as the Thermalright Assassin King 120 SE White ARGB match light motherboards and white chassis interiors. Check the color specification listed on the product data to ensure the heatsink fins and fan frame match your desired aesthetic.
Frequently asked questions
Which Thermalright cooler is shortest for small-form-factor builds?
The Thermalright AXP90 X36 is the shortest option at a 36mm total height. This ultra-compact profile fits tight mini-ITX cases where clearance is severely restricted. It uses four heat pipes and supports a 95W thermal design power rating. You get direct cooling without physical interference against surrounding motherboard components or standard memory sticks.
Do Thermalright air coolers support Intel LGA 1700 and LGA 1851 sockets?
Many models support both sockets, but you must check the specific cooler specifications. The Burst Assassin 120 ARGB and Assassin King 120 models list compatibility for both LGA 1700 and LGA 1851 out of the box. Other compact models like the AXP-90 X47 omit LGA 1700 while supporting AMD AM4, AM5, and Intel LGA 1200 or 115x sockets.
What is the difference between the Thermalright Assassin X and Assassin King?
The primary difference is the number of integrated copper heat pipes. The Assassin X120 series utilizes four heat pipes to move heat away from your processor. In contrast, the Assassin King 120 SE features five 6mm heat pipes for increased thermal conduction up to 235W. Both tower models share a similar 148mm installed height for standard mid-tower enclosures.
Can low-profile Thermalright coolers accommodate 120mm fans?
Yes, the Thermalright AXP120-X67 accommodates a full 120mm slim fan while keeping overall height at 67mm. This top-down design pushes airflow across the heatsink fins and downward onto motherboard components. It pairs six heat pipes with larger fan blades to move more air at moderate speeds, unlike smaller 90mm or 92mm fans found on AXP90 coolers.
Which Thermalright coolers feature six heat pipes?
The Burst Assassin 120 ARGB and the AXP120-X67 models feature six copper heat pipes. The Burst Assassin 120 uses a single-tower heatsink measuring 6 inches tall for mid-tower cases. The AXP120-X67 positions its six heat pipes horizontally in a low-profile 67mm form factor. Both configurations maximize copper contact to transfer heat away from the CPU base.
Do Thermalright budget coolers include addressable RGB lighting?
Several models include addressable RGB lighting, while others feature an unlit aesthetic. You can choose ARGB versions like the Assassin X 120 ARGB, Burst Assassin 120 ARGB, Assassin King 120 SE ARGB, and AXP120-X67 White ARGB. If you prefer a blackout or plain build without lighting, the standard Assassin X120 Refined SE and Assassin King 120 SE offer identical cooling without LEDs.
How loud are Thermalright single-tower desktop coolers during operation?
Thermalright single-tower models are designed to operate quietly under regular desktop workloads. For instance, the Assassin King 120 SE ARGB generates a maximum specified noise level under 25.6 dB(A) while pushing up to 66.17 CFM of airflow. Its 120mm PWM fan automatically regulates rotational speed based on processor temperatures, preventing unnecessary noise when your system is idling.
