Scythe Yasya



Cooling is vital. As I sit here slowly turning into bacon in the sun, I can safely say that staying cool is a pretty important thing. Now picture a world where you would not have the liberty to move into the shade… and then all of a sudden, a large hand comes from the sky, places you on a treadmill, steadily incrementing its speed and incline until you can’t take anymore.  Granted this is not a real life scenario and more of a rotund individual’s worst nightmare but I dare say that this is exactly what a heavily overclocked processor is going through. If your abused processor had feelings, it would be shaking its logical fist at you and if it had an entitlement complex it’d be on strike before you could even say “British Airways”.

So let’s cut to the chase; what would you cool your processor with? Today there is an abundance of air cooling solutions to choose from and in all shapes, sizes and price. Starting from an entry level, we have the popular Arctic Freezer series which has been on sale (in one format or the other) for ~£18 since the dawn of time. These coolers offer a significant improvement over Intel and AMD’s reference coolers, but what if you’re after something more capable?

As of late, the regularly mentioned cooler brands include Noctua, Prolimatech and Thermalright… but what happened to Scythe?

Much of Scythe’s success can be dated back to 2006/2007 with their Ninja and Infinity heatsinks. For an extended period of time, these two products were among the list of “must have” coolers. While they were potent offerings, the release of competitors from a number of manufacturers left the Ninja and Infinity far behind. However, today is Scythe’s opportunity to shine once again with the release of their new Yasya Heatsink.

At ~850g, the Scythe Yasya is a hefty fellow. That said, with a conventional tower layout, a copper based construction and a strong 120mm fan, we could well be onto something promising.

Packaging & Initial Impressions

Of all heatsink manufacturers, it is hard to overlook Scythe's flamboyant packaging. This is most certainly a far cry from the minimalist colour schemes from the likes of Noctua and Thermalright for example, however it still serves its purpose. This is a Scythe Yasya and these are it's key features...

Out of the box, the Scythe Yasya looks mighty sharp. The most distinct feature of the cooler is it's unorthodox fin design. Scythe tout it as a T.M.L.F. (Trident Multi Layer Fin) structure. Aside being a very densely populated fin layout, the jagged surface is there to deflect air in a more efficient manner.

There are no less than six "U Shaped" heatpipes mounted to the base of the cooler. Sporting a nickel plated copper construction, we expect it's conductive ability to be sufficiently competent.

Finally the Scythe Yasya offers two mounting kits; one for Intel LGA775/1156/1366 and one for Socket AM2/AM3. Both of these use conventional push-pin and clip installations respectively. Given the cooler's weight this might raise an eyebrow, however it does make the cooler very simple to install. Enough chit chat, let's get testing.

As per usual, our CPU Cooler testing methodology revolves around a Core i7 overclocked to 4.00GHz; a clockspeed that many of you end users regularly endeavour to achieve. When a Core i7 is operating at voltages upwards of 1.350V, they are certainly not easy to tame. Like other coolers that we have tested, we test the fans at both low and high fanspeeds (9V and 12V) to ascertain the heatsink's ability to cool such a CPU with lower noise levels.

As far as consistency is concerned, all testing is carried out in a room with an ambient temperature of 20c. Results are carried out multiple times until concordant values are determined.

Thus far, the performance crown lies with the Push-Pull Noctua NH-D14. How well will the Scythe Yasya perform? Well there's only one way to find out...


After an extensive period of load testing with the Yasya's fan raised to it's maximum speed of RPM, we eventually found our i7 930 at a temperature of 77c; just 3c short of our highly regarded Prolimatech Megahalem. For those who aren't familiar with the thermal output of Core i7 processors, I must stress that this really is an impressive result. While the noise emitted from it's 120mm fan was not excessive, it was still noticeable.

For those who like their systems whisper quiet, we then proceeded to lower it's fan speed to the lowest level offered by it's controller. By running the same load test again, a maximum temperature of 84c was recorded. Once again this is 3c short of the Megahalem at it's 9V fan setting and over 10c warmer than the Noctua NH-D14. Some promising results have been achieved today, but now it's time to conclude.

Scythe are back and unlike our football team, have actually returned with positive results.

In a nutshell, the Yasya Heatsink offers performance that is comparable to the similarly proportioned Prolimatech Megahalem. While the two products are priced almost identically, Prolimatech do not bundle a fan with the Megahalem and so your overall expense could be as much as £20 higher than the Scythe after you get round to buying one. As for the Noctua NH-D14, yes it does outperform the Scythe by significant margins however it shouldn't be forgotten that it holds a £30 price premium for this.

Like many tower coolers, we must stress that you should check that your case has sufficient clearance to fit this 158mm tall heatsink. We would hope that those who are truly serious about overclocking have bought a case that can support such coolers, but our point still stands.

All in all, we quite like what the cooler has to offer. Out of the box, you are provided with a multi socket compliant heatsink and a respectable 120mm fan to boot. The installation process is quick and simple, while the performance is very much in line with similarly priced examples. You can buy the Scythe Yasya for as little as £36.59 today, which in our opinion makes the cooler an excellent purchase. Well done Scythe.

The Good
- Competitive Performance
- Easy to Install
- 120mm fan included

The Mediocre
- Lack of bolt through mechanism may annoy Intel mount haters

The Bad
- None
