JiuShark
Jiushark is a name that most American audiences have probably never heard of before, but the company is more well-known in Asia. Founded five years ago, the first part of the company’s name (jiŭ) translates to the number nine in Mandarin, and their motto is “simplicity first, back to basics”. We’ve covered Juishark in the past, highlighting some of their unique products like the Jiushark M.2 Three, an M.2 SSD cooler that uses a radiator and fan with dual heatpipe, much like a mini CPU cooler. More recently, we reviewed the Diamante JF13K air cooler, which offers a unique top-down form factor, unlike any other cooler we’ve tested before – that is, until today. Here we are looking at the Jiushark JF13K Diamond Mini, a successor to the original, with a more compact design. Is this refined design effective enough to make it onto our list of top coolers, or was it designed just to capture attention with its unique style? We’ll have to test it to be sure, but first let’s take a look at the features and installation of this cooler.

Jiushark JF13K Diamond Mini Features
Top-down cooling design
With the JF13K Diamond Mini, Jiushark features a broad top-down heatsink cooled by two fans. The original design used two thin 120mm fans, but the mini incorporates thicker, yet smaller, 100mm fans. Jiushark’s top-down design bears some resemblance to Cooler Master’s GeminII cooler, which was on the market about 15 years ago.
Over 45mm RAM and large heatsink compatibility
The RAM I use on my test bench for the i7-13700K has a 45mm height, which may cause compatibility issues with some coolers, but the JF13K Diamond Mini has ample space and is also compatible with tall SSD heatsinks up to ~50mm in height.
Limited SFF Compatibility
In fact, a cooler like the JF13K Diamond is likely more suited for an SFF system – and I had originally planned to test it on my compact Ryzen 7700X system. However, you’ll need about 2.5cm of side space for it to fit. The cooler’s width makes it incompatible with ITX cases that lack space on the motherboard side, like the SFF case I use, the Silverstone SUGO 14.
Two 100mm fans
One cooler encompasses more than just the heatsink or radiator. Included fans have a significant impact on cooling and noise levels, as well as the cooler’s appearance in your case. The fans included with the JF13K Mini are a bit different than what you’d see on other coolers – they are 100mm in size and 25mm thick. You have 3 fan styles to choose from, depending on the Mini model chosen: solid black, ARGB black, or ARGB white. My main complaint about these fans: they run much louder than necessary. As you’ll see in the benchmarks on the second page of this review, the difference in cooling performance when running them at maximum speed (46.9 dBA) and the noise normalized to 38.2 dBA is almost non-existent. There’s no reason for these fans to be making so much noise.
