DeepCool’s Gamer Storm Captain EX 120 is a compact All-In-One (AIO) liquid cooler with a unique appearance that really catches the eye. I am going to take a look at the cooler and see how it performs compared to some other solutions. I am going to be using the AM4 platform to test how well it can dissipate heat from a mildly overclocked Ryzen 7 1800X processor. The cooler retails in the UK for around £59.99.

Unboxing the DeepCool Gamer Storm Captain EX 120

The pump block itself is really eye catching. It features a unique “Steampunk” style housing which almost looks like a Reactor of sorts. The pump itself is powered by a 3-pin fan cable and doesn’t support PWM. The clear ring inside the top of the block pulsates with a red light when powered up.


Installation of the cooler is actually very easy, and the instructions are well documented and laid out. I will be installing the cooler on an AM4 system.

From the User Manual for AM4

The cooler doesn’t use AMD’s default backplate but instead uses a universal one that is included. For AM4, you slide some long screw mounts through the correct holes on the backplate (They are labelled) and place the backplate behind the socket with the screw mounts going through the holes. For this I needed two hands and had to lay my case down on its side but you could do it standing up easily.

Next, you take the metal stand offs and screw them in place over the screw mounts. These stand-offs have a non conductive sticker at the base to prevent shorting.

Once the stand-offs are in place, you place the metal bars on top of the screw mounts and then screw in some caps to secure them.

Once the mounting kit is installed, it is simply a matter of placing the cooler on top of the CPU and screwing in the screws on each side. The plate itself doesn’t make contact until it is screwed in quite far. The screws themselves will stop once it has reached optimum pressure, so there is no chance of over-tightening.

Test platform and Fan curves

To test the DeepCool Captain, I used the following test platform:

  • AMD Ryzen 7 1800X overclocked to 3.925 GHz
  • CPU Vcore at 1.27V
  • GSkill TridentZ 2x8GB 3200 MHz C14 RAM
  • MSI B350 PC MATE motherboard
  • Seasonic FOCUS Platinum 850W
  • Noctua NT-H1 Thermal paste used on ALL coolers

In addition, I used a fairly aggressive fan curve. The curve maintains 50% RPM on the fans until 62C is reached and ramps up to 100% fan at 70C.
