When you are buying a new more powerful processor to replace your old one, you often ask yourself if a cooling system upgrade is also necessary. And while this question is not very difficult to answer for the mainstream user, because all contemporary cooling systems worth $25 or higher can in fact cope just fine with any CPU out there in its nominal operation mode, then overclocking fans should really think this matter through thoroughly. Very often it is the cooler that limits overclocking of processor from the upper price segment, which have an unlocked clock frequency multiplier. So, today we are going to check out six processor coolers using our new six-core Intel Core i7 extreme Edition i7-980X processor and will see how its overclocking success depends on the cooler choice. And since four coolers out of these six are new to us, let’s talk about them in a bit more detail first.

Testing Participants

Scythe Yasya (SCYS-1000)

The new creation of the well-known Japanese Scythe Co., Ltd. is called Yasya and is shipped in a medium sized box with the cooler photo on the front:

As usual, Scythe’s packaging is completely covered in all sorts of information starting with the list of supported platforms and finishing with warranty details:


There is a smaller box at the bottom of the main package, which contains two pairs of retentions, a manual, a pack of SilMORE thermal paste and two wire clips for the fan:

Scythe Yasya tower cooler is made in Taiwan. It consists of a copper nickel-plated base with six copper heatpipes 6 mm in diameter soldered to it. They hold aluminum heatsink plates:



The cooler with a fan attached to it weighs no more than 848 g. it measures 130x108.5x159 mm. the two schematic images below show more details pertaining to the dimensions of this cooler:


The main peculiarity of Scythe Yasya cooler is wedge-shaped plates that are shifted away from one another:

The Japanese engineers called this technology “Trident Multi Layer Fin Structure”. It is supposed to reduce the fan airflow resistance and therefore increase the heatsink cooling efficiency. We have already seen many solutions like that, but Scythe Yasya seems to have it implemented in the most radical way. I also have to add that all plates are polished to mirror-shine. Their impeccably smooth surface should also improve the airflow, which means that Yasya should be pretty effective even with low-speed fans, which should undoubtedly be great news for the owners of quiet systems.
