Specifications, Availability and Pricing
The Rasetsu draws heat up starting with a 2mm thick, nickel plated, copper base plate. Sandwiched between the base plate and the aluminum pre-cooler, the six 6mm heat pipes are soldered in place and begin the removal of heat from the processor. After two cleanly made tight bends, these pipes travel up and into one of two groups of fins. All of the fins are 0.3mm thick, with one smaller group of fins; twenty-two on this side. The other set is thirty fins in count and sits roughly 18mm from the other set, allowing room for the six heat pipes to travel up inside the cooler body. Offsetting the cooler will help with issues like memory heat spreader conflicts, and allow the Rasetsu to fit in much tighter spaces. Also helping the Rasetsu fit into more places is the fact that it is 130mm square and only 141mm tall.
As Scythe has typically done, they mated the Rasetsu with a Slip Stream fan that is both PWM controlled and offers manual control via a hardwired dial. If you don't like noise while your system runs, even though the motherboard can give varying voltage via the PWM feature, you have the option to lower these voltages even further. On its lowest setting the Slip Stream will top out at 1340 RPM, delivering up to 76.53 CFM of air flow with the benefit of only 27 dBA of noise. If you want a little more overclocking headroom, or in the warmer months, just turn up the dial and allow the fan to run at full speed. Doing so will unleash the Slip Stream, producing up 1900 RPM, just over 110 CFM of air, and gaining a fair bit of noise as well. With unique styling, a high performance fan, and mounting for processors in sockets 478 and newer Intel Processors, along with Socket 754 and newer AMD processors, the Rasetsu is a very accommodating CPU cooler.
If you are still reading this far into the review, I have to think there is some interest, and you want to know what the Rasetsu is going to set you back. Well, if you go through the usual outlets, you can find the Rasetsu on shelves at Newegg.com for $49.99. No free shipping deals this time around, so in total it will cost you in the realm of $58 to get one to your door. If you shop around a bit, and maybe don't mind dealing with some less reputable names than Newegg, there are better deals to be had by almost $10, but I cannot recommend them as I have never bought from them myself. Choices are kind of slim, though. Aside from the two I was talking about, there are only four or five others currently with stock of the Rasetsu, so that will be reflected in the scoring.
