ARCTIC Liquid Freezer II 240 Liquid CPU Cooler Review

All-in-One (AIO) liquid coolers have been around for years, helping DIY PC enthusiasts move into the next realm of component cooling and system silence. And while many companies have started to shift their focus on AIOs to the cosmetic side of things via RGB pumps and fans, ARCTIC has kept their focus on device performance and value. With the Liquid Freezer II 240 AIO, ARCTIC has completely redesigned their pump for maximum performance and low noise output. Equipped with a few unique features, the Liquid Freezer II 240 is next up on our new liquid cooling test bed, so let’s take a closer look!

ARCTIC’s retail packaging for the Liquid Freezer II 240 is quite compact when you consider that there is a full AIO system within. The cardboard box offers a matte finish, with a black and white illustration of the cooler on the front panel. While the Liquid Freezer II 240 is compatible with both Intel and AMD systems, a large Ryzen sticker is prominently located on the front of the box, just above a large label indicating the inclusion of ARTCIC’s MX-4 thermal paste. A 2-year warranty label is also included on the front of the box, which should give potential customers ease of mind when considering this AIO for purchase.

The back of the box shows off a few of the more unique features of the cooler, which we will cover in the next section, but this is a great way to differentiate this product from the competition. The sides of the box are adorned with specification tables and feature lists rounding out the exterior.

As we mentioned previously, the retail box for this cooler is quite small, and when opened up, we can see that ARCTIC has carefully snaked the cooling lines around to make things fit. Protecting the pump and block combo is a box-like outer package, while the cooling lines, radiator, and fans are wrapped in plastic for protection during shipment.

As with any AIO cooler, the Liquid Freezer II 240 comes packed with all of the mounting hardware you need for both Intel and AMD systems. This includes multiple sets of screws, standoffs, mounting clips, brackets, etc. A small pouch of MX-4 thermal paste is included for a single-use application. Additionally, a small manual card with a QR code is included in order to guide buyers to a digital copy of the installation manual. And while we applaud ARCTIC for this eco-friendly option, we do like to have a physical manual to refer to during installation.
