Cooling technologies for all-in-one (AIO) systems are constantly evolving to address performance issues over time. The latest innovation seeks to tackle the problem of performance degradation due to flux residue with a simple yet effective solution—a flux filter that keeps unwanted particles away from the CPU block.
Innovative Cooling Solution: Valkyrie’s Flux Filter
AIO cooling systems often struggle with maintaining performance as they age. This degradation typically results from flux residues that dislodge and circulate through the cooling loop, eventually clogging the microfins of the CPU cold plate. Over time, as these particles accumulate, cooling efficiency diminishes significantly.

Enter Valkyrie, a Chinese cooler manufacturer, which has developed a groundbreaking “Flux Filter” to combat this issue. This filter effectively prevents flux residue from entering the loop and clogging the cold plate’s microfins. In addition to this, Valkyrie has adopted a “low flow” radiator manufacturing technique, reducing particle production during operation. By improving the radiator’s manufacturing process, the risk of obstruction caused by flux is significantly minimized.
To ensure an optimal result, each radiator is meticulously inspected internally before assembly. The flux filter itself is strategically placed at the radiator’s inlet, capturing flux residue effectively and preventing it from compromising the loop’s performance. This smart design ensures that AIOs maintain superior cooling performance over an extended period. Valkyrie’s VK N360 model is a testament to these innovations, showcasing remarkable benefits from these upgrades.
Proven Performance of the VK N360
When subjected to rigorous testing, the VK N360 proved its mettle. The cooler functioned with coolant temperatures exceeding 90°C for 72 continuous hours, yet demonstrated minimal performance degradation. The test results showed only a 1°C increase in temperature, highlighting the cooler’s outstanding efficiency and durability. Such advancements in cooling technology reaffirm the potential for AIOs to deliver consistent performance over longer periods, setting a new benchmark for cooler manufacturers globally.
