A Closer Look

Utilizing a tried-and-true dual-tower design, the R1 Ultimate changes things up a bit with its "Jet Fin Air Acceleration" technology, which is a fancy way of saying that there are two sets of fins at varying distances to help accelerate air out of the heatsink. This design works out as forty-two fins on the front half of each tower and fifty-three fins at the rear of each tower and is different to the more typical design that uses standard aluminum fin stacks.


The heatsink has a slightly offset design. It is not, however, the same as with the R1 Universal. The Ultimate has less of an offset and, as such, doesn't offer perfect memory clearance even with a slim fan attached. That aside, the cooler is fairly attractive overall, and with its CUSTOMOD covers, you can make it fit just about any system.


A smaller CRYORIG logo in gray adds a bit of contrast to the plastic cover and an otherwise nearly solid black design. The seven Ø6 mm heatpipes are evenly spaced out throughout both towers, with a slight offset to each other for better heat transfer. The aluminum fins are soldered to the heatpipes, and the base is relatively smooth and clean, but lacks a mirror finish.


The black and gray fans make use of CRYORIG's HPLN (High Precision Low Noise) sleeve bearing. Both XF140 fans feature an RPM range of 700-1300 with a maximum airflow of 76 CFM.


Finally there are the CUSTOMOD covers. Available in white (R1 Universal), black (R1 Ultimate), orange, green, blue, and red. While not included with the R1 Ultimate, users can purchase any of these separately.
