Scythe Kama Cross Heatsink Review Specifications: Overall Dimensions: 140x120x132mm Fan Dimension: 100x100x25mm Fan Speed: 1500rpm Noise Level: 22.0dBA Airflow: 42.69cfm Bearing Type: Sleeve Weight: 530g Socket Compatibility: Intel 478/775, AMD 754/939/90/AM2 The Kamacross features a unique crossed heatpipe design with a total of 80 fins attached, 40 on each side. The close proximity of the fins is an indicator that the heatsink will need a fan that can churn out high pressure and airflow to perform. A total of 3 heatpipes are used to transfer heat from the bottom plate to the fins attached. With this design, the fan attached can also effectively cool the base plate, heatpipe as well as the area around the CPU. The heatsink also comes with a 100mm fan which is pretty weak and unable to sustain the heatload of the Intel Pentium XE processor that we will testing with later, but fret not, you can always swap the fan out! As 100mm fans are not commonly available in the mass market, Scythe has also made mountings for the enthusiasts to remove the default fan and attached a 120mm fan if needed. Kudos to Scythe for such an innovation. This time round, instead of the usual RCCM2 mounting mechanism that Scythe adopted for their higher end heatsinks, Scythe has chose to use a screw on mounting mechanism that's similar to their Ninja revision B heatsinks. Something that's not as convenient, but will allow you to mount your heatsink with ease without having to remove your mainboard from your case. SetupContenders for the throneBenchmarks All Benchmarks were conducted at ambient temperatures of approximately 26 degree celsius. Load temperatures was obtained running 4x instant of Prime 95, 2x small FFT and 2x large FFT for 30minutes. Test Setup: Intel Pentium XE 955 (3.46Ghz, Dual Core Engineering Sample, 130W TDP) Asus P5WD2-E Premium Rev 1.01 Cosair XMS8000UL 512MB x2 Nvidia 7800GTX 512MB graphic card Silverstone ST65ZF *The Scythe KamaCross, Noctua NH-U12F, Scythe Infinity and Ninja ran a Silverstonetek FM121 120mm Fan ran at max speed (39.5dBa, 110CFM).' Please do note that results using the defualt 100mm fan on the Scythe Kama Cross is not recorded as the heatsink could barely keep the Presler XE 955 stable at load. Results - CPU Temperature The Kama Cross didn't come across to me as such a strong competitor at high fan speeds; the performance is literally equivalent to the BTF 90 and Infinity, but do note that you will have to bear with a slightly noisier setup if you're using such a high speed fan. Unlike the rest of the heatsinks in the test, the Kama Cross will not perform with a fan spinning at low speeds. Results - System Temperature System Temperatures recorded is higher than the rest of the side blowing heatsinks, which can be attributed to the close proximity of the fins resisting airflow from reaching the rest of the system components.
