Top-down CPU air coolers are often the preferred cooling solution for systems with limited vertical space, such as low-profile setups. However, when it comes to high-performance processors under heavy loads or overclocking, these coolers may not provide sufficient cooling performance.
But JIUSHARK, a Chinese brand, has introduced a new top-down CPU air cooler called the JF13K Diamond that aims to change this. Despite costing just $40 US, this cooler boasts an impressive cooling potential of up to 265W TDP, making it a suitable rival to even liquid coolers. So, whether you’re using a standard case or a low-profile system, the JIUSHARK JF13K Diamond offers an affordable and effective cooling solution.
The cooler features a large diamond-shaped heatsink that provides a larger surface area for heat dissipation, which can result in better cooling performance. The cooler also has six heat pipes that efficiently transfer heat from the CPU to the heatsink.
However, the performance of a CPU cooler depends on several factors, including the design of the heatsink, the number of heat pipes, the size and speed of the fan, and the airflow inside the case. It’s also essential to ensure the cooler is compatible with your CPU socket and point.
With a single fan design, the current top-down CPU coolers are restricted by their limited space, making it difficult to dissipate heat efficiently. In contrast, JIUSHARK’s JF13K Diamond CPU cooler utilizes a unique diamond-shaped heatsink with six heat pipes that facilitate efficient heat transfer from the CPU. The design’s larger surface area for heat dissipation has the potential to provide superior cooling performance, setting it apart from other top-down CPU coolers, such as the NH-L12 from Noctua and the PH-TC14CS from Phanteks.
The JIUSHARK JF13K Diamond CPU cooler is designed as a top-down cooling solution incorporating a finned aluminum heatsink with seven heat pipes extending from the bottom base plate over the CPU to the large heatsink. It is fitted with two 120mm fans that have been shortened to only 15mm in height. The fans have a speed range of 800-1800 RPM, delivering an airflow of 23.46-64.51 CFM. Power to the fans is supplied via a 4-pin PWM connector.
This CPU cooler has been engineered to be adaptable with small form factor cases and motherboards, thanks to its compact size of 241x121x92mm. Additionally, the cooler offers a generous amount of clearance of up to 59mm over the DIMM slots and 50mm over the I/O cover, ensuring compatibility with a wide range of motherboards. The cooler’s top-down design is particularly noteworthy as it extends over the DIMMs and VRMs, providing extra airflow and cooling to these essential components.
The cooling performance of the JIUSHARK JF13K Diamond CPU cooler is remarkable, as it can cool up to 265W TDP, a performance level comparable to liquid coolers.
According to the manufacturer’s test data, the JIUSHARK JF13K Diamond top-down CPU air cooler can effectively cool a Core i9-11900K processor at power levels of up to 217W, with temperatures staying at a reasonable 85C. This is particularly noteworthy given the high operating temperatures typically observed in Rocket Lake CPUs. In fact, the cooler is able to maintain safe temperatures even at higher power levels, with the CPU temperature only reaching 100C at 251W, which is still below the TJ Max limit. Moreover, no thermal throttling was observed, indicating the cooler’s ability to dissipate heat effectively.
One downside to the JF13K Diamond is that it is currently only available in China. If you live outside of China, you may have to go through a reseller to get your hands on one. Nonetheless, the JF13K Diamond’s performance and affordability make it a compelling option for anyone looking for a top-down CPU air cooler.
The JIUSHARK JF13K Diamond top-down CPU air cooler is a unique and impressive cooler that offers high cooling performance at an affordable price. The cooler is also compatible with small form factor cases and motherboards, making it a versatile option for builders. Considering its impressive performance and affordable price, the JIUSHARK JF13K Diamond top-down CPU air cooler is definitely worth considering for those who are able to purchase it.
