This Low Profile Twin-Fan CPU Cooler Claims It Can Cool Up to 265 Watts

According to a report from IT Home, cooler manufacturer Ninesharks has developed a very unique CPU cooler, called the JF13K Diamond that has the appearance of a low-profile CPU cooler but claims as much cooling power as a 240mm AIO liquid cooler.

The cooler features a distinctive shape, with the form factor of two low-profile CPU coolers, joined together. This is a radical change from the dual fan tower-style coolers we're accustomed to seeing. But, the low profile form factor gives the cooler more surface area which could improve its cooling performance. An added bonus is that since the fans are firing downward directly onto the motherboard, surrounding motherboard components will get extra indirect cooling as well.

The radiator itself has 7 heat pipes and is equipped with two extra-thin 15mm fans, with a size of 241 x 121 x 92mm - which equates to a slightly skinnier 240mm radiator from an AIO. The CPU mounting mechanism sits directly in the middle of the radiator, with the two fans flanking each side of the motherboard.

The height compatibility is somewhat limited with a maximum height of 59mm supported on the memory side of the motherboard, and 50mm on the other side - where the rear I/O sits. In a worst-case scenario, both the DRAM and rear I/O cover might be too high to fit the JK13K's lengthy radiator.

According to IT Home, the JF13K Diamond was tested cooling a Core i9-11900K at 85 degrees Celsius, with the chip running at 217W of power consumption. We don't know what CPU benchmark was running, but the cooling results are very similar to the y-cruncher results found in our 11900K review, where the chip was running around 75-85°C on a 280mm Corsair H115i liquid cooler.

Currently, the JF13K Diamond is priced at 269 yuan in the Asia market, approximately $39, but it is not available in the United States at this time. Hopefully, the JK13K's unique cooling characteristics will garner enough popularity to warrant a US release sometime in the future.

    Isn't hat just a GPU cooler at that point? XD

    Last time I sse a dual fan cooler cheap like these 2005 2006 maybe ... found it... https://www.anandtech.com/show/2221
    I want one of that cool the motherboard and other components... my last "c" cooler is the noctua cp12se works right but don't have the punch to cool high tdp cpu

    Not gonna lie, this is exactly the kind of CPU heatsink I've been wanting for a while. I hope it's good and comes to the US

    It's not. And it won't. Which is exactly why you'll see marketing articles about it, but will never see an actual review by any reputable reviewer. Only company related shucksters.

    Unique, where? This has been done already.

    "An added bonus is that since the fans are firing downward directly onto the motherboard, surrounding motherboard components will get extra indirect cooling as well."
    All while those same fans get plenty of sloppy seconds from the gpu(when it's active) and fight with the 3-4 rear + top exhaust case fans... mighty fine indirect cooling, right there.
    These types of coolers would be more effective if the fans were oriented in the OTHER direction; complements those rear + top exhaust fans and doesn't take in as much gpu waste.
    The push fans are from the time when side panel ventilation was more common.

    I see this cooler doing poorly primarily due to reviewers/users not setting them up in the right environment.

    If these designs were worthwhile, you can rest ASSURED that companies like Noctua, Thermalright, Scythe, Silentium, Cryorig, Phanteks and other top notch brands would not only have them but they'd be available everywhere by now. Plus there'd AT LEAST be major reviews of them, even IF the potential production costs caused them to not be feasible. There isn't, so they aren't. Barring incremental improvements in EXISTING cooler designs through better designed chambers, fin stacks and surface area improvements, the only way air cooling is going to get any better than it currently is is with the addition of active phase change refrigeration designs.

    Luckily, Cooler Master kept working on it, and here is I think their latest in the series.

    Using direct-contact heat pipes, I think that model performs considerably better. Still not enough to compete with the best air coolers, but decent for its price and size.

    I currently have a Scythe Big Shuriken II Rev. B, with a Noctua 150 mm fan on it (in place of the stock 140 mm fan), and it keeps my 130 W CPU in the low 70's @ peak load. TIM is Arctic Cooling M4.

    That's what I do. Updraft configuration. It contributes directly into the stream of the case exhaust fan. The aluminum, windowless case helps, as well.

    And I think most of us with at least moderate experience testing many different cooler models, even at hobbyist levels, would agree with this. Which makes so much sadder that they keep trying to act like it's some great new thing instead of simply saying if you flip the fans over you will see at least some moderate benefits of it, rather than just crawling down and sucking on the hind tit.

    I guess these sort of cooler design is not taking off because it kind of disrupts the airflow in a typical MATX/ ATX case where the intake fans are situated in the front, and with top and rear exhaust fans. Tower coolers generally take the intake air from the front and exhaust the hot air directly out with the rear and top case fans. In this case, the downward blowing fans are blowing the hot air downwards to the motherboard as oppose to directly out. So I guess the ambient temp in the case will gradually build up. I do like downward blowing coolers for low power CPUs, but I think it will be a problem for higher end CPUs.
