Japanese cooling expert Scythe announcing the third version of it’s “Grand Kama Cross” Top-Flow CPU cooler. New Scythe Grand Kama Cross 3 is based on the same extraordinary X-Structure concept as the predecessor, allowing especially efficient cooling of both the CPU and the surrounding components such as VGA cards, VRMs or RAM.
Scythe engineers redesigned the Grand Kama Cross 3 with the goal to significantly improve the overall performance. Instead of using regular 6-millimeter copper-heatpipes, Scythe has exchanged the two copper-heatpipes in the center against two with 8-millimeter diameter. Fine-tuning the manufacturing process allowed to further increase the efficiency of the heat transfer between the copper baseplate and the copper-heatpipes. Another difference to the predecessor is that both the copper baseplate and the four copper-heatpipes have been completely nickel-plated for the Grand Kama Cross 3. The engineers have re-designed the two aluminum-fins blocks and fitted the fins with a special saw tooth tread design. The new design has lowered both the operating noise at higher fan speed ranges and the air resistance, resulting in improved cooling performance.
Grand Kama Cross 3 comes with a pre-installed 140 mm axial-fan from the GlideStream series. Thanks to its larger diameter and PWM-support, sufficient airflow between 29,90 and 97,18 CFM at noise levels from 12,5 to 30,7 dBA is assured. Fan speed can be adjusted individually according to the CPU temperature by the motherboard stepless in the range from 400 to 1.300 RPM. The special grooved blade design of the GlideStream 140 case fan benefits the top flow design of Grand Kama Cross 3 CPU cooler.
Even more easy and secure mounting is achieved thanks to the re-worked backplate-based mounting system. Further advantage is the support for latest Intel sockets, such as LGA1151, and LGA1150, LGA1155 as well as LGA 775, 1156, 1366, and LGA2011(v3). The list of compatible AMD sockets includes AM2(+), AM3(+), FM1and FM2(+). All the required mounting clips and screws are supplied with the Scythe Grand Kama Cross 3, as well as a wrench, screw driver, multi-lingual manual and quality thermal grease.
