Thermalright has expanded its CPU cooling lineup with the introduction of the Royal Pretor 130 Vision and Royal Pretor 130 Digital dual-tower air coolers. Both models build upon the existing Royal Pretor 130 design by adding integrated top-mounted displays for real-time hardware monitoring and customisation.
The flagship Royal Pretor 130 Vision features a 3.95-inch, 480×480 LCD screen mounted on top of the heatsink. Connected through an internal USB 2.0 header, the display works with Thermalright's software to show system metrics, custom images, wallpapers, GIFs, and animations. In contrast, the Royal Pretor 130 Digital uses a dedicated monitoring display that shows only real-time data, including CPU temperature, package power consumption (W), clock frequency (MHz), and memory usage percentage.
Both coolers share the same physical hardware, featuring a 130x140x165mm dual-tower heatsink with six 6mm nickel-plated copper heatpipes and a nickel-plated C1100 copper base. Airflow is handled by a 120mm TL-H12W-X28-R9 PWM fan rated up to 2400RPM and 98.2CFM, paired with a central 130mm TL-HD13W-X28 PWM fan rated up to 1750RPM and 81.88CFM. S-FDB V2 bearings are used on both fans.
Compatibility spans Intel LGA115X, 1200, 1700, 1851, 2011, and 2066 sockets, as well as AMD AM4 and AM5 platforms. Thermalright will offer both variants in black and white finishes, though official pricing and release dates remain unconfirmed.
KitGuru says: At this point, most AIO coolers have a display attached to them. The same trend is now taking over the air cooler market too.
Cooler Master, a global leader in PC components and thermal management solutions, has announced the V8 ACE 3DHP, a flagship single-tower CPU air cooler featuring the company’s patented 3D Heat Pipe (3DHP) technology. Designed for high-performance processors, gaming PCs, workstations, AI development, 3D rendering, and video production workloads, the new cooler aims to deliver dual-tower-class cooling performance in a more compact design.
The V8 ACE 3DHP introduces a hybrid cooling architecture that combines two 3D heat pipes with four traditional heat pipes. This design improves heat transfer from CPU hotspots into the fin stack while maximizing fin utilization. Rather than increasing the size of the heatsink or adding more conventional heat pipes, Cooler Master uses its 3DHP technology to improve heat distribution and cooling efficiency within a single-tower form factor.

CPS PCCooler has launched the TR620M X, a relatively compact dual-tower air cooler with a single fan. However, that single fan can spin up to 5000RPM, faster than most other PC cooling fans on the market.
According to ITHome, the heatsink measures 115x106x94mm and uses a pure-copper, nickel-plated, reflow-soldered base. The same source states that the heatsink towers are treated with an anti-oxidation spray coating and utilise six 6mm heat pipes to transfer the thermal energy generated by the CPU.
Airflow is provided by a single fan (100x100x25) equipped with a Japanese NMB dual ball bearing. The fan operates at a maximum speed of 5000±10%RPM, delivering a maximum airflow of 105.42CFM and a static pressure of 11.85mmH2O. These figures, as you'd expect, come with a pretty high noise level, up to 45.66dB(A).
According to the official product description, the TR620M X supports a wide range of mainstream workstation platforms. Compatibility includes Intel LGA3647 (narrow type) and 4677, as well as AMD sTRX4, sWRX8, TR4, SP3, TR5, SP5, and SP6. The TR620M X is currently available in China for 439 yuan (£48), with an initial launch price of 339 yuan (£37). Availability outside the Chinese market has not yet been provided.
KitGuru says: For the general consumer, something like the PCCooler TR620M X cooler may be a bit too loud. However, if you don't mind the noise, it should offer a good amount of performance.
GAMEMAX SIGMA 620 WH is designed for users who want both strong cooling and a unique visual touch in their PC build. For a long time, I have personally preferred air cooling because it is simple, reliable, and requires very little maintenance. But in recent years, many liquid coolers have become more attractive because they include small displays that show system information or custom images. Now, GAMEMAX has brought this idea to air cooling with the SIGMA 620 WH, which makes it stand out from many traditional tower coolers.
What makes this cooler interesting is the 2.8-inch customizable LCD screen placed on the top. It can show real-time system information or even display custom images and videos, which adds personality to the setup. At the same time, it still focuses on strong cooling performance with six 6 mm heatpipes, dual 120 mm fans, and support for CPUs up to 245W TDP. This combination allows it to handle powerful processors while also improving the overall look of the PC build.

A closer look
Heatsink
The Sigma 620 uses a single tower heatsink design. The cooler measures 120 × 114.2 × 158.8 mm and has a net weight of 154 g. It is available in black and white, and our review unit comes in white. The whole heatsink, including the heatpipes, is finished in full white, which gives it a very clean look.
The heatsink includes 48 aluminium fins. At the center, it uses 6 superconducting composite heatpipes, each with a 6 mm diameter. These heatpipes run through the tower and connect to the base. The sides of the heatsink fins use a raised design, which allows the fan clips to fit securely into the fins for mounting the fans.
The cooler also includes an anti-insect intrusion design. The bottom panel uses an extended design that helps seal the hardware rack holes.
On the top cover, there is a 2.8-inch LCD monitor. This screen sits neatly on the top of the heatsink and adds a modern touch to the cooler.
Fans
The cooler includes two 120 mm fans, each measuring 120 × 120 × 25 mm. The main fan uses a regular blade design, while the secondary fan uses a reverse blade design.
Both fans use rifle bearings. The fan frame colour is white, and each fan has 9 blades. Each fan also includes 28 ARGB LEDs.
Both fans run at 12 V rated voltage with a 5 V start-up voltage. The rated current is 0.22 A for the main fan and 0.2 A for the secondary fan. The rated power is 2.64 W and 2.4 W.
The fan speed ranges from 800 to 1800 RPM ±10%. Maximum airflow is 71.66 CFM for the main fan and 70.71 CFM for the secondary fan. Maximum static pressure is 2.54 mmH₂O and 2.1 mmH₂O. The maximum noise level is 35.5 dBA and 42 dBA.
Both fans have a rated life of 30,000 hours. The connector includes 3-pin AURA ARGB and 4-pin PWM. Each fan also has soft rubber pads on the corners to reduce vibration. A thin ARGB light strip runs along the side of the fan frame, which remains visible and glows in a style similar to infinity fans.
Installation
The installation process of the Sigma 620 is simple and easy to follow. The steps are clearly explained in the user guide, so even new users can install it without confusion. One good thing is that the heatsink can be installed without attaching the fans first, which makes handling and mounting much easier.
The mounting system feels secure once installed, and the cooler sits firmly on the CPU. The included brackets and accessories make the process smooth for both Intel and AMD platforms.
Clearance
When it comes to RAM clearance, the space is quite tight. As seen in the images, the cooler sits very close to the RAM slots, leaving limited room on that side. If you are using RAM with tall heatsinks, you may face compatibility issues. Low-profile RAM would be a better fit in this case.
On the other hand, the clearance on the opposite side is much better. There is enough space around the motherboard area, so it does not cause any issues with other components. You can raise the fan position slightly to get more RAM clearance. However, this comes with a small trade-off, as the fan may cover the RGB lighting, which affects the overall look. Overall, the installation is easy, but the RAM height should be considered before installing this cooler.
Software
The software for the Sigma 620 is very basic, but it gets the job done. The interface is simple and easy to understand, so you don’t need much time to get used to it.
Most of the software is focused on CPU temperature monitoring and screen themes. You can view real-time system data like CPU usage, temperature, and other basic stats directly on the LCD screen.
There are a few pre-built themes available, which you can apply easily. These include system info layouts and simple visual designs. You can also adjust settings like brightness and screen rotation.
One useful feature is that you can create your own custom theme. You can add your own images or simple layouts to personalise the display according to your setup.
Here are a few examples of themes displayed on the Sigma 620 cooler screen.
Testing and thermal performance
We tested the GAMEMAX SIGMA 620 in the GAMEMAX Leader 2 case using an Intel Core i7-12700K with the MSI MPG Z790 CARBON MAX WIFI II motherboard. The room temperature during testing was 28°C. At idle, the CPU stayed around 39°C with low fan speed. The fans remained quiet, and noise was barely noticeable.
Under load, we ran a CPU-Z stress test. The CPU reached around 185W, and temperatures went up to 72°C. The cooler handled this load well. Fan speed increased smoothly, and noise stayed at a comfortable level. There was no thermal throttling, and the system remained stable. For a heavier test, we used the AIDA64 single FPU stress test. In this test, the CPU again stayed in the 180–190W range, and temperatures reached 85°C. This is on the higher side but still within safe limits. The cooler maintained stable performance without any issues.
Overall, the Sigma 620 performs well for a high-performance air cooler. It handles heavy loads without stability problems. The claimed 245W TDP support also seems reasonable based on these results, as it can manage around 190W+ comfortably.
Final thoughts
The GAMEMAX SIGMA 620 WH offers a good balance between performance and design. It stands out by adding a customizable LCD screen, which is not common in air coolers. This gives it a unique touch while still keeping the reliability of traditional air cooling.
The build quality is clean and consistent. The full white finish, including the heatsink and heatpipes, looks neat inside the case. The ARGB lighting and top display add extra visual appeal without feeling too much. In terms of performance, the cooler handled the i7-12700K well. It managed around 190–200W loads while keeping temperatures in a safe range. Fan noise is also controlled, staying quiet at idle and reasonable under load.
The software is simple and basic, but it works fine. It mainly focuses on CPU temperature monitoring and screen themes. You can choose from a few built-in themes or even create your own custom theme, which adds a bit of personalisation.
There are a few things to consider. RAM clearance is tight, especially with taller memory modules. You can adjust the fan position for more space, but it may cover the RGB lighting. The GAMEMAX Sigma 620 WH delivers stable performance and adds a unique feature with its LCD screen. Based on its overall performance and usability, I would give it the EnosTech Performance Award.
ID-Cooling is continuing its aggressive expansion of the Frozn lineup with the launch of the Frozn A620 SLK. This new CPU air cooler introduces a “hybrid” architecture , integrating two “half-tower” fin stacks into a single 160mm-tall unit.
The primary innovation of the Frozen A620 SLK (via ITHome) is its heatsink design. Unlike most dual-tower coolers with two separate heatsink blocks, the Frozn A620 SLK has only one large heatsink with enough space to fit a 120x25mm fan in the middle. This embedded central fan and an external front fan are positioned in opposition to create high-velocity airflow through the fins. The central fan is the AM-120-K, a 120×25 unit capable of reaching 2500 RPM with a static pressure of 3.65 mmAq. This fan utilises a tool-less mounting system for easy maintenance. To ensure maximum RAM compatibility, ID-Cooling has paired this with the AF-120 SLIM (120×15) in the front, which provides 65.2 CFM of airflow despite its 15 mm low-profile frame.
Thermal transfer is handled by six 6mm heat pipes and a precision-machined copper base, enabling a nominal TDP of 260W. This puts the SLK in direct competition with many larger, bulkier dual-tower coolers that often interfere with high-profile memory modules or VRM heatsinks. The 160mm height ensures broad compatibility with standard mid-tower cases.
Compatibility is also a major highlight, as ID-Cooling is already looking ahead. In addition to current staples like Intel's LGA 1700/1851 and AMD's AM4/AM5, the Frozn A620 SLK officially supports the upcoming Intel FCLGA1954 socket. This inclusion suggests that the cooler is prepared for the next generation of Intel desktop processors.
KitGuru says: ID-Cooling was very creative with its fin stack geometry. By sandwiching a full-sized fan between two halves of a tower and slapping a slim fan on the front, they've essentially built a smaller dual-tower cooler that won't bully your RAM.
