Price-Performance Champ

The Freezer 33 TR is an updated version of our award-winning Freezer 33 and specially designed for the new AMD Ryzen Threadripper CPU. The base of the heatsink has been enlarged to fit the massive AMD SocketTR4 and, equipped with a BioniX F120 fan, it pushes the cooling performance further to cope with the 180 W TDP of the AMD Ryzen.

The Freezer 33 TR is the perfect CPU cooling solution for enthusiasts who want to build High-End Desktop Computer on a budget.

Maximum Quietness, Minimum Vibration

Extremely quiet operation through a newly developed motor guarantees long sessions without annoying noise.

ARCTIC's new motor of the BioniX Fans eliminates vibrations directly at its source, in particular at the motor. The ARCTIC motor absorbs 95 % of vibrations compared to a conventional DC motor. Thus, there is no need for rubber spacers due to the steady torque and smoother switching of the magnet field.

Maximum Performance for Highest-End CPUs

The contact surface of the Freezer 33 TR heatpipes does not cover the full protection cap, but, more importantly, are right where the processor DIE is and cover even the largest versions (16 core) completely. This leads to maximum performance.

Wide Range of Regulation

With the range of 200 to 1800 RPM the BioniX F120 fan of the Freezer 33 TR is controllable with the PWM Sharing Technology to regulate the fan speed as needed.

Extended Life Span

10 °C lower motor temperature doubles the life span. The BioniX gaming fans have a four times longer service life through low coil temperature. Therefore, we extend the warranty to 10 years.

Improved Heat Dissipation

The Freezer 33 TR has off-centered heat pipes that dispense the heat in a more efficient way than the centered ones of its predecessors. Also, the layout of the 49 aluminium fins creates micro vortices that boost the airflow and circulate it around the heatpipes.

Thermal Coating

A newly developed thermal coating creates micro-turbulences with a special surface structure. Combined with offset heat pipes this leads to an optimised heat-dissipation and to an increased cooling performance.

Enlarged base for
AMD Threadripper

The Freezer 33 TR is specifically designed for the new
AMD Ryzen Threadripper sTR4 Processor and delivers
extremely quiet cooling for High-End Desktop Computers.

Enhanced Bearing

Due to a new alloy/lubricant combination developed in Germany, the friction within the bearing is reduced and a greater efficiency is achieved. This way, there is less heat development as well as less bearing noise and you can enjoy a longer service life of your cooler.

Easy Installation & Safe Transportation

Thanks to different mounting models for various sockets, a backplate and a significantly lower weight compared to the i30,
the Freezer 33 TR is not only fool-proof to install, but also absolutely transport safe.

Unlimited RAM Compatibility

Thanks to the compact dimensions of only 123 mm x 150 mm x 80 mm, there are almost no restrictions when using RAM modules. Even
RAM modules with larger heat sinks can be mounted without any issues and are not blocked by the CPU Cooler.

"Small - but crazy powerful"
Considering the size of the cooler, no one was expecting miracles. At first glance, it is hard to believe that such a small cooler can handle 32 Thread and 180 Watt Processors. And yet! This little cooler coped with the task.
With the Freezer 33 TR, ARCTIC has expanded the Freezer 33 series with a tower cooler, which in our tests not only score through simple assembly and good procession. The installation of the Freezer 33 TR is very simple and is completed... [more]
Mod Your Case
It’s hard to believe that a $45, very basic-looking air cooler can handle all the heat coming off of a 16-core, over-clocked, high-end desktop CPU. … It just seems pretty impressive and surprising to me.
"An excellent solution for Threadripper"
The Freezer 33 TR has a ten-year warranty, it looks nice thanks to the thermal coating of the heatsink and it does not cost too much.

Unexpectedly powerful Threadripper Cooler!
I was really impressed. It's a great cooling option for a threadripper at a great price, and I think it looks pretty good too. The testing was done with 1950x with all cores overclocked and the temperatures weren't issue at all.
Jarrod's Tech
Especially with the second fan and the additional airflow, there should be no bottlenecks. We also liked the look and processing. The black coating upgrades the radiator and the red accents of the fan make it a bit more conspicuous.... [more]
In this black and white combination, Freezer 33 TR looks just great, and because of that the quality feels better than with the regular Freezer 33. Performance of this BioniX fan equipped cooler is OK if you have no desire to overclock the... [more]

Which thermal paste can I use?read

We recommend using MX-2 or MX-4 thermal paste. ATTENTION! Please do not use liquid metal thermal paste. The component gallium causes aluminum to corrode and become brittle.
