ARCTIC Liquid Freezer II 420 - Multi-compatible All-in-One CPU AIO Water Cooler, Efficient PWM Controlled Pump, Fan speed: 200-1700 rpm (Controlled via PWM), LGA1700 compatible - Black

Product Information

The Arctic Liquid Freezer II averaged about 8-10 microns depth from the 0-point, with minimums and maximums at 2 microns and 48 microns. Most liquid coolers actually come from only a few companies: Asetek (the largest), CoolIT (growing in the consumer space), Apaltek, Dynatron, and any number of other smaller suppliers.

Shifting the rear exhaust fan down helped a bit but I pulled the front of the case off to move the cables around enough so the radiator would set in place. North of the socket, aligned with the top-center of the cooler and center of the fan opening, the FPM measured between 190 and 212. Before putting this chart up, a few important points: First, this is all relative, so our measurement points aren’t designed to test the motherboard, but rather to test the cooling capabilities of the CPU cooler on top of it.That’s why it has an asterisk next to it – the data isn’t directly comparable, since liquid temperature is less in control at this low of a static pressure. Removal gave 1-2mm clearance, enough for the radiator to sit flush against the I/O shield, and enough to let the screw holes align between the case and rad.

The Arctic Freezer requires the AM4 mounting plate, fairly standard for most CLCs, and uses just four screws through the rails that mount according to the socket. Additionally, all coolers shipped by ARCTIC are already compatible with Intel's Alder Lake and Raptor Lake LGA1700 processors. The upper-left side measured at 422FPM, as we seemed to find the exact angle at which air exits the chassis the fastest. Of course, it also comes ready with 450mm long braided EPDM (ethylene propylene diene monomer) tubes and an PWM pump/waterblock combo (2000RPM/copper plate) equipped with a top 3000RPM VRM 40mm fan (which indeed helps with VRM temperatures).

The Arctic Liquid Freezer II 280 is what we’re reviewing, although variants at 120, 240, and 360 are also prominently featured online. The VRM fan clearly does something, and temperature improvements will follow the more even FPM on either side of the VRM heatsink, but we also want to be clear that a top-mounted radiator would also benefit the VRM.

The all-in-one cooling handles the entire cooling requirements — even of the most powerful processors from Intel ® and AMD ®. For the Arctic Freezer at 35dBA, we see a 51-degree load temperature, putting the cooler just below the Kraken X62 while remaining significantly cheaper. AMD's upcoming 7000 series AM5 processors also come with multi-die layouts and can therefore benefit from the Liquid Freezer II's unique offset mounting.The fan is PWM-controlled and can cool your voltage converters and the socket area almost inaudibly by up to 15 °C especially in overclocking scenarios, with insufficient VRM cooling or in cases with low airflow and thus allows continuous high load. Arctic cooling’s Liquid Freezer II came right in time for Zen 2 system builds toward end of 2019, but that was when we were in the middle of upgrading our testing methods.

Our next chart continues with the 3950X 200W load, but allows all the coolers to run at 100% fan speed during the test. We can revisit in the future if needed, but that’s the only question mark left after the review process: Arctic’s pump design is new, something we’ll look at in our tear-down video coming up shortly, and a new design means we have no reference point for endurance and reliability. The northwest corner of the cooler, measured at the top-left screw of the mount, measured at about 197FPM toward the VRM. i’ve got an arctic liquid freezer ii 420mm (actually 458mm from end to end) and am having a tough time finding a case to fit it while still allowing the hoses to reach the cpu.For reference, this overlay will show the baseline numbers with radiator fan measurements in the top-center spot.
