Arctic has formally introduced its Freezer 50 TR cooler for AMD’s Ryzen Threadripper processors, which promises to remain quiet even when the CPU gets hot. The socket TR4-only cooler comes with two fans, has multiple heat pipes, and weighs more than 1.2 kilograms. And, for the multi-colored lighting enthusiasts among us, it's equipped with 13 addressable RGB LEDs.

The Arctic Freezer 50 TR borrows its design from other so-called ‘mega coolers’: it has a massive dual-tower heatsink featuring 104 aluminum fins, while eight U-shaped 6-mm heat pipes that form the base cover the part of the IHS of the Ryzen Threadripper CPU ‘right where the processor’s die is’. Moving air from the massive heatsink is a 120-mm plus 140-mm fan set, with Arctic's fans using fluid dynamic bearings. While the mismatched fans are unusual, Arctic says that using two fans of different sizes increases airflow and therefore improves performance. Depending on the load, the fans will rotate at 200 ~ 1800/1700 RPMs, so it should be very quiet under light loads.

It is noteworthy that when the Freezer 50 TR cooler was originally showcased early this year, it actually advertised as being able to go passive under low loads. However this feature is absent from the final version, and while Arcitc hasn't specifically said why, it's not hard to imagine thermal stability proving to be a greater concern than expected from such a large (and power hungry) chip like Threadripper.

When it comes to dimensions, the whole construction of Arctic’s Freezer 50 TR measures 147.8×149.5×165 mm and leaves a RAM clearance of 37.5 mm. While the cooler certainly cannot be called compact, it should fit into most enthusiast-grade PC chassis.

The manufacturer does not disclose the cooler’s rated TDP, but says that it can cool down Ryzen Threadripper 2990WX as well as CPUs ‘of 32 cores and beyond’. So as we've seen with some other air coolers of this size (which can handle upwards of 340W) it's a reasonable bet that the 50 TR can dissipate at least 250 W of heat, leaving some additional headroom for overclocking and/or future processors with a higher TDP.

Finally, as is increasingly customary for enthusiast-grade cooling systems these days, the Arctic Freezer 50 TR comes with 13 addressable RGB LEDs. These can be controlled using software from leading motherboard makers as well as a standalone controller (to get it, one will have to buy an appropriate version of the cooler).

    This would have been a poor passive cooler, low-loads or otherwise. The fins are too densely packed, the fans overlap much of the entry and exit surface, and airflow can only go in one direction.
    These are all good things for an active cooler, but passive cooling is a different challenge.

    I'm sure the LEDs do all the magic :).

    Directly heatpipe contact on a giant chip like Threadripper? Wow just wow...

    Was thinking this too. Individual chiplets/dies will dump their heat most effectively straight up through the IHS, though it does "spread" the heat somewhat it shouldn't be a huge issue, I just wonder why no one used a Vapor chamber on TR for air-cooling. Would be the best way of getting that heat off the MCM.

    Or, just use a liquid cooler.

    You can always mod the vapor chamber on if you really want.

    $70 is a fantastic price for this class of cooler.

    Is AnandTech not allowed to quote the text on the back of the box?

    You know, the part that says "64-core CPUs".
  • Chaitanya - Monday, October 21, 2019 - link

    AMD has already launched 64 Core Epyc CPUs and so its not a surprise to find it on marketing material of a CPU cooler. Whats surprising is the sentence directly implies 64 core sTR CPU coming in weeks time.

    My understanding is that **push-pull** coolers typically add little, if any, efficiencies.

    That is, however, a good-looking unit at a reasonable price.
    Look forward to reviews ...

    I wonder how much crossover there is between the TR market and the gamer RGB market.
