All-in-one liquid cooler Thermaltake CL-W401-PL14BL-A 14 cm Black

TOUGHLIQUID 420 EX Pro is an all-in-one liquid cooler in an all-black industrial style with an infinity mirror lighting element and a 420 mm radiator designed for 140 mm fans. The kit includes three TOUGHFAN EX14 Pro fans and a slim 27 mm radiator with a 20 mm thickened copper chamber, a high-performance copper base plate and an upgraded MagForce 2.0 quick-connect system for faster, more reliable fan attachment. The cooler is supplied with brackets compatible with current Intel and AMD sockets, including LGA1700 and AM5.

Advantages

The all-black industrial cap with infinity mirror lighting provides a distinctive visual effect while the MagForce 2.0 pogo-pin contact pads (twice the size of the previous design) improve tolerance and reduce faulty alignment during daisy-chaining or cable connections. The three included 140 mm TOUGHFAN EX14 Pro fans use a redesigned 9-blade Liquid Crystal Polymer (LCP) structure offering up to 70.8 CFM airflow, 3.19 mm-H2O static pressure and a noise level around 22.6 dB-A. The slim 27 mm radiator with a thickened 20 mm copper chamber and a copper base plate increase cooling efficiency without increasing installation complexity.

Suitable for

• PC builds that require a 420 mm AIO liquid cooler
• Systems using 140 mm fan mounts
• High-performance desktop CPUs including Intel LGA1700 and AMD AM5
• Users who prefer reduced cable clutter with quick-connect fans

How to use

Install the radiator in your case where 420 mm radiators are supported, mount the three 140 mm fans to the radiator, and connect the fans using the MagForce 2.0 quick-connect system or standard fan cables as required. Attach the cooler’s copper base plate to the CPU using the supplied brackets and follow the manufacturer’s torque and thermal paste instructions. Connect pump and fan power to the appropriate motherboard headers and verify fan and pump operation in BIOS or monitoring software before normal use.

Recommendations

For optimal performance, install the radiator in a location with good airflow, use system fan headers that support PWM control to regulate fan speed, and ensure the pump header remains powered at all times. Periodically check mounting tightness and system temperatures; no coolant refill is expected under normal operation due to the low evaporation tube design.
