ENERMAX has an alert out to folks regarding fake AQUAFUSION II 240 and 360 liquid coolers in the market in China. Make sure you check the serial number before you buy to ensure your safety and warranty coverage. The advice is particularly for those released around November 2024.
Check serial numbers to avoid fake units and voided warranties
The specific models in question here are the AQUAFUSION II 240 and the AQUAFUSION II 360. Only products that match certain serial number intervals are considered genuine. This is important for your safety and warranty coverage.
Genuine units will come with a serial number in the range of 2533120142257~2533120142456. Anything else is a counterfeit product. The fake products have serious safety hazards with issues of not being properly sealed and may lead to leaking.
ENERMAX will not offer any warranty, repairs, compensation for leaking, or technical support for any non-genuine units. Users should look for the serial number on the box and/or the product. It's the only way to make sure you have full support and safety.



The serial number range is tight. 200 units is a small batch. This looks like a specific regional shipment leak.
Where exactly should I look on the box to find that serial number? Is it on the barcode sticker or printed directly?
It is on the product label itself and the outer cardboard box. Check both to be safe. The range is 2533120142257 to 2533120142456.
I just bought one online. 😬
I have used liquid coolers for years without checking serials. I trust the retailer to be honest. This warning feels excessive.
It is not excessive. Leaking coolers can destroy your motherboard. The article states these are unsealed. You risk your entire build.
I would rather see independent thermal benchmarks than worry about serial numbers. At least tell me if it runs cool.
I care about noise levels. My current cooler is loud. I hope the genuine ones are quiet enough for my streaming setup.
RAM prices are crazy anyway. I cannot afford to break my PC twice. 🤔
I will stick with air cooling. It is safer and cheaper. I do not want to risk a leak for aesthetics.
