Frequently asked questions
Does the Thermalright Assassin King 120 SE support LGA 1851?
The standard AK120 SE model does not list LGA 1851 in its compatibility specs. You should choose the non-SE Assassin King 120 variant instead. That model explicitly includes LGA 1851 support alongside AM4, AM5, and LGA 1700. Both versions share the same five heat pipe design and fan features.
What is the maximum height for the Assassin King 120 SE?
The AK120 SE measures 5.83 inches in height. This dimension applies to the standard SE, ARGB, and White ARGB variants. If you need a lower profile for ITX builds, consider the AXP-90 X47. That model stands only 1.85 inches tall and is designed specifically for compact cases with strict height limits.
Which Thermalright cooler is best for ITX cases?
The AXP-90 X47 is the recommended choice for ITX builds. It features a low-profile design with a height of just 1.85 inches. This allows it to fit into small form factor cases where standard towers will not. It supports major sockets including AM5 and LGA 1851 while maintaining a 47mm height specification.
Does the AK120 SE have ARGB lighting?
The standard AK120 SE model does not include ARGB lighting. It focuses on quiet operation and practical cooling. If you want addressable RGB effects, select the AK120 SE ARGB or the White ARGB variant. Both of those models explicitly list ARGB in their attributes while retaining the same five heat pipe construction.
How much does the AK120 SE weigh?
Most AK120 SE models weigh 1.4 pounds. This includes the standard SE, the non-SE version, and the White ARGB variant. The ARGB-only model is slightly lighter at 1.15 pounds. These weights reflect the single-tower design with five copper heat pipes and an included 120mm fan.
What is the difference between single and dual tower designs?
Single tower coolers like the AK120 SE use one fan and one heatsink block. They are compact and fit in most mid-tower cases. Dual tower models, such as the FC140, use two heatsink blocks and often two fans. This design provides higher cooling capacity for high-performance CPUs but requires more space inside the case.
Is the FC140 compatible with LGA 1851?
The FC140 dual tower cooler does not list LGA 1851 in its compatibility data. It supports AM4, AM5, LGA 1700, LGA 1200, and LGA 1151 sockets. If you need LGA 1851 support with a dual tower design, check the specific product page for updates. The AK120 SE non-SE version does support this newer socket.
