What stands out
- Six 6mm pure copper heat pipes with AGHP 5.0 technology for efficient heat transfer.
- Twin-tower design with undulating aluminum fins to maximize surface area.
- Crooked neck structure prevents interference with tall RAM sticks.
- Includes a Y-adapter cable for easy connection to motherboard fan headers.
- Soft silicone corner pads on fans to reduce vibration and noise.
Who it fits
Good fit for
This cooler suits builders with mid-tower cases that can accommodate a 155mm height. It is ideal for users with tall RAM, as the offset design keeps clearance open. The six heat pipes provide strong thermal performance for standard desktop workloads. It fits well on both Intel LGA1700/LGA1851 and AMD AM4/AM5 sockets. If you need reliable cooling without complex liquid systems, this dual-tower setup delivers consistent results through its efficient fin design and fan speed.
Who should skip it
You should look elsewhere if your case has a strict CPU cooler height limit below 155mm. The dual-tower design is physically large and may not fit in compact micro-ATX or mini-ITX builds. Users seeking silent operation might find the 1800RPM fan speed too loud for their preference. Additionally, if you require RGB lighting on the cooler itself, this model focuses on functional aluminum fins rather than aesthetic illumination. Check your case specifications carefully before purchasing.
Verdict: The Royal Knight 120 SE offers robust dual-tower cooling with smart clearance design. It is a practical choice for standard towers and tall RAM setups.
Key Specs Explained For You
6 Heat Pipes
This cooler uses six pure copper heat pipes to move heat away from the processor. The pipes transfer thermal energy from the base to the aluminum fins efficiently. This setup helps maintain lower temperatures under load. You should look for this count when comparing air coolers, as more pipes generally mean better heat distribution across the tower structure.
Dual Towers
The dual tower design features two separate heatsink structures with fins. This increases the total surface area available for air cooling. More surface area allows the fans to dissipate heat more effectively. When shopping, compare this against single-tower models to see if your thermal needs require the extra mass and fin density provided by this twin-tower configuration.
120mm Fan Size
The fans measure 120mm in diameter, which is the standard size for many air coolers. This size balances airflow and noise levels well for most cases. You can easily find replacement fans if needed. Compare this with 140mm fans to see if your case has the depth required for larger units, as 120mm fans fit into tighter spaces without blocking RAM.
1800RPM Fan Speed
The fans operate at a maximum speed of 1800 RPM. This speed generates airflow to push air through the fins. Higher RPMs increase cooling potential but also raise noise levels. When comparing specs, check if this speed suits your noise tolerance. You can often adjust this speed via motherboard settings to balance performance and quiet operation during idle times.
155mm Cooler Height
The total height of the cooler is 155mm. This dimension determines if the unit fits inside your computer case. You must measure your case clearance before purchasing. Compare this height with other coolers to ensure it does not interfere with side panels or large RAM sticks. Lower profiles allow for smaller cases, while taller units often offer better cooling performance.
Design And Build Quality
The listing describes a twin-tower heatsink with an aluminum fin array. The base and six heat pipes are pure copper. This material mix aims to balance heat absorption and surface area. The crooked neck design shifts the upper tower slightly. This layout helps avoid interference with tall RAM modules and graphics cards. You do not need to raise the front fan, which simplifies installation in compact cases.
Dimensions are listed as 122 by 114 by 155mm. The 155mm height requires clearance above the CPU socket. You must check your case specifications before buying. The dual fan setup includes one standard 120mm fan and one thinner 120mm fan. The thinner fan reaches 1800RPM according to the data. This speed provides higher airflow for the front position. Soft silicone corner pads are included to reduce vibration noise.
Mounting hardware covers AM4, AM5, and Intel LGA1700, LGA1851, and older sockets. A Y-adapter cable is provided to connect both fans to a single motherboard header. This feature helps when motherboard fan headers are limited. The finish is functional aluminum and copper. There is no mention of RGB lighting or aesthetic coatings. The design prioritizes thermal performance and component clearance over visual flair.
Setup And Everyday Use Guide
Installing this cooler requires matching the mounting grommets to your specific socket. The listing confirms support for Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM4 and AM5 platforms. For AMD systems, you must use the original motherboard backplane. Follow the instruction manual or installation video for correct alignment. The cooler stands 155mm tall, so you must verify clearance against your case side panels before mounting. The twin-tower design features a crooked neck. This offset shifts the upper tower away from the memory slots. You can install tall RAM modules without raising the front fan. The front fan is a thinner 120mm unit spinning at 1800 RPM. It sits closer to the heatsink to improve airflow. The middle fan is a standard 120mm model. Both fans use S-FDB bearings for longevity. The package includes soft silicone corner pads. These reduce vibration and noise during operation. You will also receive a Y-adapter cable. This cable combines 3-pin and 4-pin connectors. It allows you to plug both fans into a single motherboard header. This solves port shortages on many motherboards. The six 6mm pure copper heat pipes use AGHP 5.0 technology. This design manages heat distribution regardless of the cooler’s orientation. Daily use involves connecting the fan cable to the CPU_FAN header. The system will manage fan speeds based on thermal load. The aluminum fins and copper base work together to dissipate heat efficiently. Ensure your case has sufficient depth to accommodate the 155mm height. This setup provides a straightforward installation process for compatible builds.
Before You Buy
Before you buy this dual-tower cooler, check your case clearance. The unit stands 155mm tall, which may not fit in compact chassis. Verify your RAM height. The design leaves space for modules, but very tall heat spreaders might still interfere with the front fan. Ensure your motherboard has two free fan headers. The listing includes a Y-adapter cable to split one header, but you need an available port to start. This model targets mid-range to high-end processors. It pairs well with other Thermalright options if you need larger cooling for overclocking. For basic office builds, a single tower might suffice. Keep the silicone pads clean to maintain low noise levels. The AGHP 5.0 pipes handle vertical and horizontal mounting well. You do not need software for operation. Just connect the fans and secure the grommets. This is a straightforward hardware solution for standard desktops.
Check before you buy
- Check your PC case supports 155mm cooler height.
- Verify RAM height does not block the front fan.
- Ensure your motherboard has two free fan headers.
- Confirm your CPU socket matches AM4, AM5, or LGA1700.
