Enermax LiqTech TR4 240 Processor liquid cooling

Manufacturer: Enermax
Category: Computer Components
Sub-Category: Computer Liquid Cooling
EAN: 4713157723352


The AIO liquid CPU cooler LiqTech TR4 was developed in cooperation with AMD for the AMD RYZEN Threadripper processors. The extremely powerful processors are mounted on the TR4 socket, which, in contrast to previous AMD sockets, occupies a much larger area. Conventional cooling systems that have been retrofitted to the TR4 socket can often not cover the Threadripper's entire heat spreader. Therefore Enermax designed LiqTech TR4 to make use of the entire surface for cooling and also offers an extremely high cooling capacity of up to 500W+ TDP to keep the beast under control.

- Maintenance-free Cooling System
All-in-One liquid CPU cooler with pre-filled coolant offers best usability and maximum cooling performance for powerful PC systems.

- 240mm Dual-Radiator
The LiqTech TR4 240 comes with an extra thick 240mm dual fan radiator (39mm height) to enhance the heat exchange capacity and improve the cooling performance. The 500W+ TDP provides incredible cooling for over-clocking.

- 360mm Triple-Radiator
The LiqTech TR4 360 offers extra cooling performance with a long triple fan radiator to enhance the heat exchange capacity and improve the cooling performance. The 500W+ TDP provides incredible cooling for over-clocking.

- 280mm Dual-Radiator
The LiqTech TR4 280 comes with an 280mm dual fan radiator for a large heat exchange capacity and high cooling performance. The 450W+ TDP provides superior cooling for over-clocking.

Cold Plate

- 100% sTR4 IHS Coverage
Tailored to 100% cover AMD Threadripper’s integrated heat spreader (IHS) for uncompromised cooling performance.

- Shunt-Channel Technology
Patented cold plate design for maximum cooling performance. The shunt inside the micro fin structure minimizes the “Boundary Layer” effect, eliminates hot spots much quicker and ensures a perfect heat dissipation.

- Illuminated Enermax logo
The white glowing logo on top of the cold plate acts as a power-on indicator.


- Powerful pump design
A robust pump with precision engineering delivers high flow rate up to 450 L/h for superior cooling performance.

- Ceramic nano PI bearing
Silent and long lasting high-efficiency ceramic bearing pump with 100,000h MTBF.

- Anti-vibration
Rubber pads at the corner provide noiseless stable operation.

- High Pressure Blade Design
High pressure blade design is a precision engineering of the fan blade angle and shape calculation. The blades concentrate the airflow to the centre of the fan.

- The 2nd Generation of the Patented Twister Bearing
Smooth and persistently silent operation due to the patented Twister Bearing Technology. The second generation of the bearing guarantees up to 160,000 hours MTBF.

- Premium weaved tubing
The flexible and long lasting polyamide rubber tubes ensure zero permeability. 400mm long tubes for easy system installation.

- AMD SocketTR4 Ready!
Quick & user-friendly mounting system for TR4 / SP3 sockets supporting AMD® RYZEN Threadripper CPUs.
