Closer Look

It is time to take a closer look at the cooler.


The radiator measures 151x120x27mm, with the 27mm representing its slim profile. When paired with 25mm fans, its total height reaches 52mm. Fully assembled, it measures approximately 53.50mm due to the fan screws’ thick heads. Constructed from lightweight aluminum, it features an angular edge design.

The radiator boasts a 20 FPI count, ideal for fans with high airflow and air pressure. Its thinner far chamber, typical in AIO coolers, maintains 105mm spacing between mounting holes. The fins area spans around 120mm, while the radiator’s length reaches 151mm.

PRO TIP: Pay attention to the orientation of the radiator and fan. Typically, you want the fan to pull cool air through the radiator and exhaust it out of the case.

Notably, there’s no protective plating beneath the mounting holes. Be cautious when installing fans to avoid damaging the fins, which could impact performance or even cause radiator leakage.

This cooler is using flexible rubber tubing with no sleeve. The length of the tube is 326mm. The tubes have OD of 9.72mm as measured with a digital caliper. Barbed fittings can be seen from the above picture.

There is a sticker pasted on the side confirming that the Asetek is an OEM of this unit.

Water Block

Let’s take a look at the water block of this cooler.

The pump housing is made of the plastic. There is a lid on the top of the block with a white diffuser in a circular design.

In the circle’s center, the TT premium brand logo stands out, accompanied by the Thermaltake text. These feature frosted white diffusers beneath, illuminating when activated. The entire block sports a circular matte black finish.

On the pump housing’s front, left, and right sides, no branding appears – they’re sleek, solid surfaces. Two cables emerge from the block’s left side: a 3-pin power cable and an LED cable.

The pump’s power cable is flat while the LED cables are braided. One thing that I have observed is the extra-ordinary length of the LED cables on this cooler which makes the cable management task more challenging.

We’ve got two 90° barb fittings on the pump housing’s backside. These fittings allow flexible tube rotation to suit your needs. Notice the groove on three sides of the pump housing, between the upper and lower chambers. This spot is where the housing clamping happens, accommodating the Intel and AMD mounting rings.

The cooler comes with pre-applied thermal paste. Lately, Asetek OEM coolers have significantly enhanced their thermal pastes. The performance difference between the stock paste and Noctua NT-H1 is now minimal. A transparent cover protects the pre-applied paste. The copper base is around 52mm in diameter and held in place by 8 screws on the pump housing.

I have had one complaint with this design which is there was no way for the user to lock the mounting ring/bracket on the block on its own and it makes the installation process tedious as the user has to hold the ring mounted block so as to ensure that ring does not displace.

Thermaltake sent us a new plastic bracket with four edges. We’ll place the ring on the block and secure it by attaching the plastic bracket underneath. This makes installing the mounting ring/bracket easy and secure. Props to Thermaltake for this clever, straightforward fix!

Here is a quick look at the pump specifications:

Pump speed 3000 RPM
Pump power rating 12VDC (3.9W at 12V)
ARGB LED power rating 1.06W at 5V

You would need to multiply the RPM reported in the UEFI/BIOS with 2 to get the effective or true speed due to the bipolar motor.


Thermaltake has provided their popular Pure 120mm fan with this cooler.

The Pure 12 features compression blades, hydraulic bearing, and a 16.8 million colors LED ring with 9 addressable LEDs that is ready to sync with 5V RGB capable motherboards from Asus, Gigabyte, MSI, and AsRock. It has a black color frame.

The mounting holes feature gray rubber pads to minimize vibration. Nine lightly frosted blades compose the fan, with a black sticker on the hub sporting the TT premium logo. The frame’s corners slope downward, and one side bears arrows indicating airflow direction and blade spin.

On the fan’s back, a sticker on the motor hub showcases the Thermaltake brand and TT premium logo at the top. This fan operates with a DC Brushless motor and is manufactured in China.

A 4-arm structure connects the motor hub and blades to the frame, with a widened arm housing a clamp to secure power and LED cables. The frame boasts an identical design on both sides. The fan draws a current of 0.70A.

Here are the fan specifications:

Variable Value
Dimension (mm) 120x120x25
Speed (RPM) 500~1500
Static Pressure (mmH₂O) 1.59
Air Flow (CFM) 56.45

RGB Lighting

This ARGB Sync Edition fully syncs with Asus AURA Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Lighting, and ASRock RGB LED solutions. I tested it on the Asus Strix X470-F, and the cooler synced seamlessly with the motherboard’s lighting. If your motherboard doesn’t support this, Thermaltake includes a dedicated lighting controller for you.

The controller is in black color. It has a TT premium logo printed on the top. There is a blue LED indicator right next to the TT logo. There are three buttons on the controller:

  • Mode
  • Color
  • Speed

Here are the different options we have with these options:

LED Modes Off, Wave, Full Light, RGB Spectrum,
Flow, Ripple, Pulse, Blink
Colors Red, Yellow, Green, Teal,
Blue, White, Purple
Speed Levels Slow, Normal, Fast, Extreme

The RGB color is only available in certain modes which are Full Light, Pulse, and Blink. 

The controller is powered by 5V SATA connector. The length of this cable is 460mm and it is braided as well.

The controller’s other cable is an LED connector, about 441mm long and braided. Here’s the deal: hook up all your ARGB devices in a series, linking them to the controller through its LED cable. Just so you know, one controller can handle up to 90 ARGB LEDs at most.

Motherboard Sync

If you wish to connect the ARGB devices to the motherboards’ ARGB lighting headers using 5V then there are two MB Sync cables included in the accessories. They are labeled as E and F.

The E labeled MB Sync cable is to be used for Asus, ASRock, and MSI motherboards as these motherboards are using 4-pin design for 5V lighting headers. The length of this cable is 900mm approximately and it is braided.

The F labeled MB sync cable is to be used for the Gigabyte motherboards as these boards are using 3-pin design for 5V lighting headers. The length of this cable is 900mm approximately and it is braided.

Simply connect the fan and the pump LED cables to the respective MB Sync cable and connect the MB Sync cable to the motherboard’s 5V lighting header. You will have to use the motherboard’s respective lighting controlling software.

The pure 12 ARGB Sync Radiator Fan and the Pump pack stunning 16.8M colors light spectrum with some vivid lighting modes to make your day and to color coordinate the build to its full effect. The overall lighting effects are sublime and evenly diffused. They are not overly done which is a plus. Here are some pictures of the lighting on this cooler.


Here are the Installation guides for the Intel LGA-20XX and AMD AM4 sockets.


  1. Install the LGA-20XX standoffs screws on the mounting holes around the CPU Socket.
  2. Install the fans on the radiator using the supplied fan screws.
  3. Place the Intel mounting ring on the block by aligning the notches of the ring to the catchers on the block’s housing. Slide it to secure it.
  4. Now, place the plastic 4 edged ring from the bottom side of the block. Push it till you hear the clicks.
  5. Place the water block on the CPU by aligning the mounting holes on the mounting bracket with the LGA 20XX standoff screws.
  6. Secure the block using the thumb screws. Use a screwdriver for this job and go diagonally for even pressure.
  7. Connect the 3-pin cable to the CPU fan header or any of your desire fan header.
  8. Connect the fan power cables to your desire fan header on the motherboard.
  9. Daisy chain the fan and the block using the LED cables and connect them to the motherboard sync cable or to the controller. Connect the Sync cable to the lighting header on the motherboard, and you’re done!


  1. Take out the AMD mounting ring.
  2. Take out the AMD mounting pin and the thumb screw.
  3. Pass the pin from either side. Use the thumb screw to secure holds the pin to the mounting ring. Make sure not to tighten the screw to its full torques. Just screw it in so that the pin is secured unlike the one shown in the below picture. The pin holder will be a bit flexible. We need that.
  4. Place the AMD mounting ring on the block by aligning the notches of the ring to the catchers on the block’s housing. Slide it to secure it.
  5. Now, place the plastic 4 edged ring from the bottom side of the block. Push it till you hear the clicks.
  6. Place the block on the CPU such as one side of the mounting bracket snuggles to the hook of the AMD stock backplate.
  7. Press the other side of the mounting ring so that the pin holder catches the hook of the AMD stock backplate.
  8. Start screwing in the thumb screw till the thread runs out.
  9. Connect the 3-pin cable to the CPU fan header or any of your desire fan header.
  10. Connect the fan power cables to your desire fan header on the motherboard.
  11. Daisy chain the fan and the block using the LED cables and connect them to the motherboard sync cable or to the controller. Connect the Sync cable to the lighting header on the motherboard. This would complete the installation.


The best thing about AIOs is the maximum clearance and compatibility with respect to the chassis, DIMM slots, PCIe slot. This cooler has no such clearance issue. The tubes are not blocking any DIMM slot and RAM modules of any height can be used. Similarly, the block is not obstructing the first PCIe x16 3.0 slot. Make sure that chassis has provision for a 120mm radiator mounting and you are good to go.
