Closed-loop liquid cooler roundup: 9 AIO coolers reviewed

  • Published in Cooling reviews

Raijintek Triton

Raijintek is a relatively fresh newcomer to the cooling scene, and in short time it managed to make a name for itself with striking and highly proficient air-coolers.

Raijintek Triton - Complete

Triton is the code-name for their liquid-cooling series, and there are several variants with different sized radiators available. However - all Raijintek AIOs come with the same pump / waterblock / reservoir and tubing, as these are the key elements that make the all-in-one so visually appealing.


Triton employs the use of a custom radiator that measures 275 × 120× 32mm, slightly thicker than most other radiators in this round-up. It accomodates 2x 120mm fans, and the layout is tightly packed, with an FPI count of 30fins-per-inch and 18 channels.

Raijintek Triton - Radiator

There is no coupler attached to the radiator, but that's because Raijintek has opted to add one to the reservoir.


Triton uses clear rubber tubing – something relatively unique amongst AIO coolers. The rubber tubes are completely transparent, which allows you to see the liquid in motion.

Raijintek Triton - Tubing

The tubing has a 9.5mm interior diameter, and a 12.5mm exterior diameter. However, even if the rubber is thick, the tubes are really flexible and prone to some serious kink, particularly if this is the first time you're installing an AIO in your PC. Some spring coils would have protected it against such incidents.

The maximum length is only 315mm, and the fittings are glued in place - so the option to customize or expand the all-in-one isn't on the table.

Pump & Waterblock

Perhaps Triton’s most striking element is the large pump /reservoir/waterblock. The custom-designed pump is able to push 120L/h at a noise-level of only 20dBA. It has an expected lifespan of 50.000 hours, or about 6 years of continuous use.

Raijintek Triton - Pump

The cold-plate is of copper make and nickel plated, polished to a mirror-sheen, literally. It comes with the same extra-large skived fin area with dedicated channels for better cooling.

2 LEDs light up inside the reservoir, lighting up the clear or colored fluid inside (depending on choice). Raijintek has also included three color packets in the box, allowing you to change the fluid color, though opening the coupler voids the warranty. 


Raijintek has included 2x seven bladed fans. What’s weird about them is that they're tethered together, using a single 3-pin connector.

Raijintek Triton - Fans 

There's no PWM controls for the fans, Raijintek instead opted to include a variable resistor for manual speed control, with no indication of actual fan-speed. This implementation is difficult to use, since you’d have to open the enclosure every time you want to adjust the RPM.

From a technical stand-point, the two sleeve bearing fans have a speed of 1000-2600RPM and an airflow of up to 100.455CFM at a noise-rating of up to 36.6dBA.


When first laying eyes on the large pump / reservoir, its sheer bulk might lead you to think it will eat up a lot of space, or cause some serious inconvenience during installation. That's not at all the case, as the mounting bracket allows the easy installation without taking too much un-wanted territory. On smaller / tightly packed motherboards, there might be some clearance issues - but for most, there should be no issues.

The installation manual a relatively short step-by-step procedure, and that's only because the cooler comes with one of the easiest mounting systems I’ve ever seen.

Raijintek Triton - Installed

The dedicated installation goes:

1. Install the universal backplate – by checking the appropriate screws for the type of CPU slot – use the manual to check the difference.
2. Add the similarly shaped bracket and screw it onto the bracket.
3. Install the pump and screw the two trapped screws onto the bracket;
4. Connect the pump 4-pin connector to & the fans’ 4-pin connector to the appropriate header;
