Scythe today introduced the Big Shuriken 3 Rev B top-flow CPU cooler. Essentially a revision of the Big Shuriken 3 from 2019, with the heatsink design being unchanged, the new Rev B comes with an updated fan, the new Kaze Flex II Slim 120 with a redesigned metal shroud, a small tube of the new Thermal Elixir 2 TIM, and out-of-the-box support for Intel Socket LGA1700.

The new included Kaze Flex II Slim is a 15 mm-thick 120 mm fan which takes in 4-pin PWM input, turns between 300 to 1,800 RPM, pushing between 8 to 48 CFM of airflow, at up to 1.360 mm H₂O static pressure. Its maximum noise output is rated at 27.8 dBA. The Thermal Elixir 2 TIM offers 3.5 W/mK conductivity, and is an aluminium-zinc based compound, with zero burn-in time needed.

The Big Shuriken 3 is one of the best low profile coolers in terms of price vs performance based in my experience. The Kaze Slim fan is whisper quiet in most cases, and even at full speed, most should not hear it, depending on how near they are to their PC. It is not the shortest low profile cooler, but for casing that can fit it, it is one of the best value.

It's nice to see small form factor parts still being made and sold, despite the fact that every chip maker seems to push for zillion Watt chips. :)

I was happy until... "The Thermal Elixir 2 TIM offers 3.5 W/mK conductivity, and is an aluminium-zinc based compound..." so it's electrically conductive. Not great. Luckily, thermal paste is the easiest thing to change, so no worries.

I would love to get my hands on Scythe's LP stuff. I also think they should refresh their old GPU cooler Musashi with the newer mounting holes.

It should not be electronically conductive.


From my understanding, the likes of Thermal Grizzly also uses metal in the thermal compound. But I believe the silicon grease covers the metal compound, thus, rendering it non electronically conductive.

That's aluminum oxide imho.

It has an excellent long-term stability and has no electrically conductivity under normal use.
Furthermore, it has a very low dielectric constant / high dielectric strength and no corrosive properties. There is no risk of short circuit, even if the thermal compound covers electrically conductive components.
You can sue them if otherwise.

I still have that GPU cooler, how ever not the fans though all the wire was junk went all brittle. But the heat sink was a good one.

I've got one of the older Big Shuriken 3's and it's always worked well for me.
Not using it now because I'm running an IceGiant.

My first look and without a proper review here being offered has me thinking of the recently introduced DARK ROCK TF 2 from be quite. The Shuriken 3 is of the same downdraft cooler design. Is the Scythe updated Shuriken 3 the same high quality as the German product? Probably not as the Shuriken does not present the quality which the DARK ROCK TF exudes from the get go. Will the Shuriken 3 engage a Noctua fan to stay even with the Germans for a virtually inaudible operation and quality assurance? Personally I love a downdraft design and will consider in the near future in replacing my 4-year old ailing AIO (noisy pump} with air. It’s been said that a downdraft cooler design provides ideal cooling, not only for the CPU, but also for the surrounding components. More bang for the buck? I would also think that a high quality air-cooler will last me 'trouble-free' for more than 4-years? Food for thought!

Don't use it. People don't buy heatsinks for the TIM that comes included. Use your preferred TIM. I am now exclusively on MX-5 because of it's outstanding performance!

To me, this looks like an improved revision to an already great cooler. Typical Scythe excellence!
