Quick Summary
The Thermalright Royal Knight 120 is a double-tower CPU air cooler with 6 heat pipes and dual 120mm PWM fans. It is built for AMD AM4 and AM5, and Intel LGA1851, 1700, 1150, 1151, 1155, 1156, 1200, 2011 and 2066 sockets, so the main check is whether your board matches one of those supported fittings.
The cooler is listed at 122 x 114 x 156 mm and is described as leaving space for RAM, which matters if your memory modules sit close to the CPU area.
Who It Is Best For
This cooler suits buyers who need an air cooler for a compatible AMD or Intel desktop system and want a double-tower design with dual fans. It is also relevant if RAM clearance is a concern or if you need to check case height before fitting a 156 mm cooler.
Key Details
| Detail | Verified information and buyer relevance |
|---|---|
| Model | Royal Knight 120, which identifies the exact cooler variant. |
| Cooling design | Double-tower radiator with dual-fan layout for CPU air cooling. |
| Heat pipes | 6 heat pipes are stated, which is a key specification for comparison. |
| Fan size | Dual 120mm PWM fans are included in the design. |
| Dimensions | 122 x 114 x 156 mm, so case height and internal clearance should be checked. |
| Compatibility | AMD AM4 and AM5, plus Intel LGA1851, 1700, 1150, 1151, 1155, 1156, 1200, 2011 and 2066. |
| RAM clearance | Leaves space for RAM, which is useful where memory modules are close to the cooler area. |
| Installation note | For AMD installation, the original motherboard backplate is needed. |
Why Buyers Choose It
- The double-tower, dual-fan layout gives a clear air-cooling format for supported desktop CPUs.
- 156 mm height gives a specific fit check for cases with limited CPU cooler clearance.
- The RAM clearance design reduces the need to raise the front fan when memory sits close to the socket.
- Compatibility across several AMD and Intel sockets makes it easier to match the cooler to the right platform.
How It Works
The cooler mounts to a compatible AMD or Intel socket using the supplied mounting grommets and the relevant fitting for the platform. For AMD systems, the original motherboard backplate is required. The dual 120mm PWM fans move air through the double-tower radiator, while the 6 heat pipes and aluminium and copper construction are part of the cooling structure.
Real World Use
In a desktop build, the Royal Knight 120 sits over the CPU area and needs enough case height for its 156 mm overall size. The stated RAM clearance is useful when the memory slots sit close to the processor socket, and the product’s compatibility list makes it important to check the motherboard socket before ordering.
What To Know Before You Buy
Check your motherboard socket carefully against the listed AMD and Intel fitments. Confirm that your case has enough internal cooler clearance for the 156 mm height, and make sure your RAM layout leaves enough room around the CPU area. If you are fitting it to AMD hardware, keep the original motherboard backplate available for installation.
Common Buyer Questions
Will this fit my motherboard?
Only if your board uses one of the listed sockets: AM4, AM5, LGA1851, 1700, 1150, 1151, 1155, 1156, 1200, 2011 or 2066.
Will it block my RAM?
The cooler is described as leaving space for RAM, which is useful where memory modules are close to the CPU area.
How tall is it?
It is listed at 156 mm high, so case clearance should be checked before ordering.
What is needed for AMD installation?
The original motherboard backplate is needed for AMD installation.
Final Buying View
If you need a double-tower CPU air cooler for one of the listed AMD or Intel sockets, the Royal Knight 120 gives you a clear set of fitment and size details to check. Confirm socket support, RAM clearance and case height before you choose it.
