Scythe's Yasya CPU Cooler is an enthusiast grade heatsink that cools very well and fairly quietly. It is unsurprising that it cools so well as it is one of the most massive coolers I have ever seen. This behemoth comes in at 130mmx108.5mmx159 mm and 848 grams. It is a large block of shaped aluminum fins with 6 doubled over heat pipes running through it.
The cooler is compatible with Intel socket 775/1156/1366 and AMD socket 754/939/940/AM2/AM2+/AM3 processors. Scythe handles this in such a way that this cooler is amazing easy to install. There are two pairs of clips that can be added, or removed, from the heatsink without the use of tools. Standard LGA775 push to connect clips are used for current generation Intel chips while all four generations of AMDs Athlon64 CPU are serviced by one cam lever clip that engages on the central lug of the AMD heatsink retention frame. The 120x120x25mm fan is held in place on the Scythe Yasya with a pair of springy wire clips. The fan spins at a between ~500RPM and ~1900RPM and can be adjusted by a dial on a back panel of your computer. The fan is powered by a standard 3-pin fan header. There are 2 more grooves in the fins that would allow the mounting of a second fan, though no extra clips were provided. In addition to the clips, Scythe also provides a small packet of thermal paste. Overall the installation was very easy. The only issue I had with installation was when it came time to close my case up. The heatsink is so large that it just barely pushes against the side of my case, making closing the case a little tricky.
The bottom plate of the heatsink seems well made. The heat pipes make excellent contact with the base plate. The surface of the base seems very smooth and shiny, with tiny ripples barely visible.
It is also very flat and without the concavity that a lot of coolers suffer from. Here is a picture of straightedge over the bottom surface. It is tough to see the straight edge because of the highly reflective base.
Now that we know about the cooler, lets get to the important numbers. Here is a comparison between the heatsink that came with an AMD Phenom X4 9600 BE, which can be seen in the below pictures.
The system that this was tested in:
Mid-Tower Case with 2 80mm fans
AMD Phenom II 720 BE X3 with the 4th core unlocked and over-clocked to 3.00GHz
XFX ATI Radeon HD 4770
600w ModxStream-Pro Power Supply
This is one intense cooler. When on the low fan setting is very very quiet and still does a great job cooling my overclocked/unlocked CPU. There was not as much difference between the high and low fan settings as I thought there should be. I suspect that this is due to the large airflow over the fins created by my power supply. Overall I found this to be a well made cooler that does a good job. The only negative was that is was so large, that it was difficult to close my case.
