Any why anyone would buy a low profile cooler just to spend extra to swap out the 15mm thin fans with standard 25mm fans, as suggested above, is just baffling to me. And they would still be 120mm fans which, as a general rule, have to spin faster (therefor louder) than a 140mm of equal quality to move the same amount of air. The example you see here was a prototype from Noctua that was showcased at Computex 2011. Noctua's prototype also featured seven heatpipes and offered 20 percent more surface area than its NH-D14 tower cooler.

It would be interesting if you'd publish an update (or maybe a new article that also includes the NH-C14S) to test the effects of an updraft configuration. Modern CPUs, whether Intel or AMD, are difficult to cool in intensive workloads. In the past reaching 95C+ on a desktop CPU might have been a cause for concern – but with today’s processors, it is considered normal operation. Similar behavior has been present in laptops for years due to cooling limitations in tight spaces. A report from IT Home claims the cooler is rated for CPUs with a TDP of up to 265W. It was reportedly tested with an Intel Core i9-11900K processor and managed to limit temperatures to 85c. a. This means no power limits on Intel’s i7-13700K, and AMD’s default power limits on AMD’s Ryzen 7 7700X.The JF13K Diamond from Chinese cooler maker Jiushark is a low-ish profile heatsink that aims to exploit surface area for maximum cooling. According to the product listing on retailer JD.com, the cooler utilizes a pair of 120mm fans in a side by side configuration like you see on a 240mm AIO water cooler. A total of seven heatpipes can be gleaned from the hero shots. It looks more like an aftermarket GPU cooler than a CPU cooling solution. Jiushark, maker of the overkill M.2-Three SSD cooler, has launched its JF13K top flow CPU air cooler featuring two 120mm fans while keeping height under 92mm. 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.

That has two benefits:

If there’s anything missing in the relatively oversaturated range of CPU coolers, it’s a properly powerful top-flow model. The Chinese company Jiushark now brings one such cooler. Although it is not a completely original design (there already has been a similar cooler), it currently makes a rather unique impression. You will look in vain for an alternative with comparable TDP to the JF13K-Diamond cooler in its price range.All testing is performed in a room with a 23 degrees Celsius ambient room temperature. Multiple thermal tests are run on each CPU to test the cooler in a variety of conditions, and acoustic measurements are taken with each result. These tests include: 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. JF13K Diamond จะใช้พัดลมขนาด 120 มิลลิเมตรแบบคู่ มองดูแล้วเหมือนเราซื้อชุดน้ำที่ใช้หม้อน้ำแบบ 240 มิลลิเมตรเลย และจะมีฮีตไปป์ทั้งหมด 7 เส้น ซึ่งก็น่าจะระบายความร้อนได้ไม่เลวเลยใช่ไหมล่ะครับ The illustration pictures also show sufficient spacing from the first PCI Express slot, indicating extra space for access to the latch for demounting an expansion card. Even an SSD with a tall heatsink can fit between it and the heatsink, as the JF13K-Diamond shouldn’t restrict the SSD in the M.2 slot from above. This probably doesn’t 100% apply on absolutely all motherboards, but the mutual compatibility (of CPU and SSD coolers) is significantly better here than with performance-comparable tower coolers, which in the traditional, vertical position encroach more into the motherboard space in this axis. The JF13K-Diamond is 121mm deep and the Noctua NH-U14S cooler is as “much” as 150mm deep. The dominant dimension of the Jiushark top-flow cooler is 241 mm, stretching almost across the entire width of the ATX format boards.

BTW, it's hard to tell from the pictures, but does that middle heatpipe really go straight in between the fans? That seems not ideal... IT Home เคลมว่า ฮีตซิงก์ตัวนี้รองรับซีพียูที่มีค่า TDP ได้สูงถึง 265 วัตต์ และได้เคยทดสอบการระบายความร้อนกับ Intel Core i9-11900K (ซึ่งคาดว่าน่าเป็นการทดสอบ Stress Test แต่ไม่แน่ใจว่ามีการ OC ร่วมด้วยหรือไม่) ปรากฏว่าฮีตซิงก์สามารถคุมความร้อนให้ไม่เกิน 85 องศาเซลเซียสได้ครับThis 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.
