Jiushark is a Chinese company that offers heatsinks. If this name doesn’t ring a bell, you should know that we talked about it here, when we announced their m.2 heatsink. This time, the brand is talking about the JF13K, a top flow aircooling heatsink in 240 mm!
JF13K: an aircooling heatsink that packs a punch!
With this model, the Chinese brand offers us an imposing cooler. Indeed, we remind you that it has two fans in 120 mm, all in top flow format. Moreover, like a watercooling radiator, the fans are mounted side by side.
This results in dimensions of 241 (W) x 121 (D) x 92 (H) mm. Despite this, it offers good case compatibility due to its limited height. In addition, under the heatsink, we have up to 59 mm available at the level of the memory strips against 50 mm at the level of the I/O Shield of the motherboard.
The heatsink also has a nickel-plated copper base. From this base, a total of seven copper heatpipes run along the length of the aluminum fin block. And for cooling, we have two fans, slims, 15 mm thick. These are PWM powered and operate from 800 RPM to 1800 RPM. At full speed, the airflow shows 64.51 CFM, but the static pressure is not known.
Regarding performance, Jiushark shares some screenshots of its heatsink capabilities. On a Core i9 11900K, the CPU was maintained at 85°C while the processor consumed 217W with a VCore of 1.3V @4.5 GHz. With a power consumption of 251W, still with a VCore of 1.3V, but a frequency of 4.9 GHz, the temperature reached 100°C.
In short, the heatsink looks promising, especially since it does not cost a fortune. Indeed, it costs 270 yuan, or about 32.66 € after conversion. The whole thing was available on JD.com as usual when it comes to Chinese products.
