Jiushark has unveiled its latest innovation in CPU cooling, the JF15K Diamond CPU cooler. This new air cooler boasts an impressive 280W TDP cooling capacity, achieved through a unique quad-fan design and a massive dual-tower heatsink. Priced under $40, it aims to deliver high-end cooling performance at an accessible cost.
Jiushark’s Cooling Evolution
Jiushark, a prominent name in PC cooling solutions, particularly in Asian markets, has a history of delivering high-performance coolers at competitive prices. Following the success of its JF13K Diamond and JF13K Mini models, which featured a top-down airflow design, the company has shifted to a more traditional, yet significantly scaled-up, tower cooler design for the JF15K Diamond.
Key Features of the JF15K Diamond
- Quad-Fan Configuration: The JF15K Diamond is equipped with four 100mm PWM-controlled fans. Two fans are positioned on the exterior of the heatsink, while the other two are nestled between the dual heatsink towers. These fans operate at speeds ranging from 1000 to 2700 RPM, providing an airflow of 19.49 to 55.46 CFM.
- Massive Heatsink Design: The cooler features a dual-fin stack design with six elongated heat pipes, spanning nearly the entire width of a standard motherboard. Its dimensions are 203mm (L) x 115mm (W) x 153mm (H), ensuring substantial heat dissipation.
- High Cooling Capacity: With a verified cooling potential of up to 280W TDP, the JF15K Diamond is designed to handle the thermal demands of the latest high-end CPUs under full load.
- Memory Clearance: The heatsink provides up to 53mm of clearance for memory modules, accommodating most standard RAM sizes.
- Broad Compatibility: It supports modern Intel (LGA1700) and AMD (AM5) sockets.
- Aesthetic Options: The JF15K Diamond is available in three variants: black with ARGB lighting, white with ARGB lighting, and a plain black version without ARGB. The ARGB models feature an illuminated accent plate on top of the cooler.

Pricing and Availability
The Jiushark JF15K Diamond is currently listed at a promotional price of 259 RMB, with an MSRP of 279 RMB. This translates to a price point under $40 USD, making it a highly attractive option for users seeking robust air cooling without the premium cost often associated with liquid cooling solutions. While initially available in select markets, broader availability is anticipated in the coming months.
