Kingcool may be a new name to many PC builders, but the people behind it aren’t new to cooling. The brand was formed last year as a sister company backed by an engineering team with decades of experience designing GPU heatsinks. Now that expertise is being funneled into CPU cooling, and the Kingcool Pure Flow 360 (2025) is positioned as one of the company’s higher-end all-in-one liquid coolers—without the premium price tag.
Priced at $89.99, the Pure Flow line comes in 360mm and 240mm versions, with both black and white options. The model tested here is the 360mm matte white version, aimed squarely at clean, modern builds where matching components matter as much as raw thermals. The design direction is also different from the usual AIO look: the CPU block is meant to resemble a custom waterblock, complete with a clear housing where you can actually see the coolant moving—especially striking once the ARGB lighting kicks in.
On the technical side, the Kingcool Pure Flow 360 uses a 360mm radiator and supports current Intel and AMD platforms, including Intel LGA 1700/1851/115x and AMD AM5/AM4. The radiator measures 397 x 120 x 27mm and is finished in white, including white-coated aluminum fins for a consistent appearance. It’s the kind of detail that makes the cooler blend nicely into all-white builds instead of looking like a black part that happens to be painted.
Cooling airflow is handled by three pre-installed 120mm FDB (fluid dynamic bearing) fans. They’re PWM-controlled via 4-pin connectors and run from 800 to 2000 RPM, pushing up to 71.89 CFM while producing up to 35.4 dBA. Kingcool also keeps installation cleaner by daisy-chaining the fans, reducing cable sprawl compared to many multi-fan radiator setups. Each fan runs on DC12V at 0.35A, with a stated 3.9W power draw, and all three include ARGB lighting to match the pump/block lighting.
The CPU block is where the Pure Flow tries hardest to stand out. Kingcool uses a full-plate, screwless copper base design intended to improve sealing and reliability by eliminating traditional screw perforation points. Internally, a 0.1mm micro-channel structure is used to improve heat transfer efficiency. The copper baseplate is large, offering ample contact coverage for today’s bigger desktop CPU heatspreaders.
Pump operation is rated between 2600 and 3400 RPM with a maximum noise output listed at 20 dBA. In real-world use, the pump remains impressively quiet for its speed, helping the Pure Flow feel more premium than its price suggests. The transparent housing also adds a “custom loop” vibe that’s uncommon in closed-loop AIOs, especially in the sub-$100 segment.
For performance testing, the cooler was paired with an AMD Ryzen 9 7950X3D on an AORUS X670E Xtreme motherboard, alongside 32GB of DDR5-6800 EXPO memory and a 1000W power supply, installed in a Lian Li O11 Dynamic XL. With the radiator mounted at the top of the case, the Kingcool Pure Flow 360 delivered temperatures in line with other well-known 360mm AIO liquid coolers. That’s an important point: nothing about its price forces you to accept “budget-level” cooling, at least in this class.
The bigger takeaway is value. The Pure Flow 360 competes where it counts—cooling performance and noise levels—while adding visual flair that many similarly priced AIOs don’t offer. At around $90, it lands in a sweet spot for builders who want 360mm AIO performance for gaming and productivity systems, but don’t want to spend extra just for branding.
What stands out most is the overall package. You get strong cooling, quiet operation, fans already mounted to the radiator to simplify installation, and a unique waterblock-inspired design paired with ARGB lighting on both the fans and pump. It also includes a 6-year warranty and wide CPU socket support for Intel and AMD, making it a practical long-term buy for new builds and upgrades alike.
There are still a couple of areas that could be better. Despite the daisy-chained fans, cable clutter can still be an issue depending on your build and how you route ARGB and PWM connections. And while the external pump housing looks distinctive, that custom-waterblock style may not appeal to everyone—some users might find it visually “busy” compared to more minimal pump designs.
Overall, the Kingcool Pure Flow 360mm AIO liquid cooler delivers the performance you’d expect from a modern 360mm cooler, manages noise well, and adds a design that genuinely looks different from typical closed-loop AIOs—all while staying under the $100 mark. For builders planning a white-themed setup or anyone wanting strong 360mm AIO cooling without overspending, it’s an option worth shortlisting.
