These Affordable CPU Liquid Coolers Can Clog And Have Just Been Recalled

Enermax Liqmax III ARGB 360 liquid cooler
Enermax makes some of the most affordable all-in-one liquid cooling solutions around, and unfortunately for a subset of owners, a few of them have been found to be defective and are being voluntarily recalled. The affected models include both black and white versions of the Liqmax III ARGB 360, and the Liqmax III ARGB 240.

Fortunately, the defect is not a leaking issue, so you don't have to worry about these coolers spraying your pricey components with liquid and potentially destroying them. Instead, affected users noticed that their CPU temperatures were higher than they should, and it turned out to be a manufacturing defect that can cause the affected models to clog over time.

Clogging is not normal behavior for an AIO cooler. In this case, however, it was discovered that impurities were being mixed inside the radiator during the manufacturing process and then accumulating inside the pump. Incidentally, MSI recalled its MAG CoreLiquid 360R and 240R coolers last month over a blockage issue as well.

Enermax maintains that only a small portion of coolers within the affected production range are affected. Furthermore, the manufacturing defect is said to only apply to affected models in the Korean region, not the US and other parts of the world.

Enermax AIO cooler serial number
If you own one of the aforementioned coolers, here's the serial range to look for...
  • Liqmax III ARGB 360 Black (the first 4 digits of the serial number are 2012)
  • Liqmax III ARGB 360 White (the first 4 digits of the serial number are 2119)
  • Liqmax III ARGB 240 (the first 4 digits of the serial number are 2012)
Cynex, an Enermax distributor in Korea, is handling the recall. It's accepting claims for the next 12 months (until April 30, 2023) and will replace potentially affected models at no charge regardless of whether there's an actual clog. It's also reaching out to registered customers. Additionally, the replacement coolers come with a 5-year warranty from the time of exchange (not the time of purchase).

The recall prompted Enermax's US division to issue a statement saying, "Moving forward, we have implemented additional manufacturing procedures from happening in the future." Hopefully that holds true, because Enermax's AIO coolers aren't all that expensive. The Liqmax III 360 sells for $94.99 on Amazon in the US, while the 240 model goes for $79.99.
