If it works, it works

Released more than 15 years ago, the Scythe Ninja Mini is still going strong. It's actually doing wonders paired with the 65W Ryzen 3 2200G in an open-air setup, keeping the AMD processor under 60°C. Aesthetics are another story (we love it though).

Fuma 2 Rev.B available for $65.99

The asymmetrical CPU cooler from Scythe is now available for $65.99. Technically not a fanless CPU cooler the critically-acclaimed dual tower will offer better cooling than the Alpine 12 Passive thanks to six heat pipes and a larger surface area. The 900g heat sink should easily handle a 35W CPU in passive mode, as long as convection is not obstructed.

Scythe Orochi Vs Noctua NH-P1

Launched in 2008 the Scythe Orochi CPU cooler reigned supreme until the 2012 release of the Nofan CR-95. Made rather cheaply the Orochi featured conventional heat pipes and cooling fins. The Orochi simply pales in comparison to the refined Noctua cooler. And yet, the dusty and oxidized giant still performs beautifully. In fact, it's almost as good as the NH-P1.

Scythe Orochi reincarnated

The upcoming Noctua NH-P1 looks very similar to the legendary Scythe Orochi, a massive CPU cooler that featured 10 heat pipes, discontinued more than 10 years ago. The Orochi was extremely effective but ahead of its time. Despite its impressive stature it was also flimsy and not particularly well made, not to mention razor-sharp. Flaws that Noctua will absolutely fix.

The Orochi is back

It's good to see the legendary Scythe Orochi back. Here, the giant heat sink is passively cooling the 65W i5-10500 paired with a GeForce GTX 1660 and a "customized" Alpenföhn Peter 2. The Streacom BC1 Mini Benchtable allows convection to occur, and facilitates access to components.

Scythe is back in the U.S.

More than 8 years after closing its US operations, Japanese cooling specialist Scythe is back with a brand new site, and a great news : their flagship Ninja 5 CPU cooler now officially supports passive cooling: "Massive heatsink and 6 sintered heatpipes provide top-tier performance and potential for fanless solution for completely silent PC." No mention of TDP limit, but the 1kg heat sink can probably handle a 65W CPU in an open-air setup.

Throwback Thursday

Back to 2009 with this 35W Athlon build, featuring the Scythe Orochi CPU cooler. This 120 x 194 x 155 mm and 1155g titan featured no less than 10 copper heat pipes. We actually owned it and it did an amazing job at cooling our 65W Intel Core 2 Duo E8400. Interestingly, Noctua's upcoming fanless CPU cooler is reminiscent of this legendary Scythe cooler.

The best fanless CPU cooler showdown 2

"I tested the six coolers in two system configurations at various power levels to see how each cooler does under the same sets of conditions. The first configuration included the Intel i7-10700 on an Asus Z490-Creator motherboard. The second included the AMD Ryzen 7 Pro 4750G on an Asus B550-F motherboard. The Fractal Design Meshify C case was used, and was stripped down, all fans, drive bays, and dust filters removed for optimal natural passive airflow. I ran Prime95’s torture test with small FFTs for half an hour during each run. This was done a total of 88 times, running each CPU under each cooler at 10-watt power limit intervals from 10 watts up to the highest power level that each cooler could handle without CPU throttling. I changed CPU power limits quickly between each test so that the coolers lost as little heat as possible. This way I could get to heat saturation more quickly during each run. CPU core temperatures were tracked with HWINFO64, saved as CSV files, and then processed in Excel. I ended up with a summary of average core temperatures for each minute of each stress test."

A unique piece

This spectacular HTPC features a 35W Athlon 3000G passively cooled by a perfectly oriented Scythe Ninja 5. The custom 3D-printed case is also a nice touch. Keep 'em coming!

Scythe Fuma in passive mode

According to HWCooling, Scythe's flagship dual tower (six 6 mm heat pipes, 920 g) is able to cool a slightly undervolted i7-5930K (140W TDP) without any fan. The 6-core 12-thread monster never reaching 90°C under heavy load.

Granted, we would never recommend such a build, but the Fuma is definitely another contender for the Intel and AMD 35W series.

Scythe Fuma announced

Scythe's first dual tower in a very long time has just been announced and it's looking sharp. The 137×149×130mm cooler is also showing some serious potential for passive cooling, thanks to its wide spaced fins.

Scythe Ninja 4 unveiled

Sold as an active cooling solution, the latest Ninja from Scythe could also work passively - with low-power CPUs - considering its sheer size (130 × 155 × 153mm) and weight (900g). After all, previous Ninja models were advertised as "fanless-ready" up to 65W TDP. More details are expected to be announced for the Europe / US launch.

A Tribute To A King : Scythe Orochi

Scythe released the Kraken 4 years ago. Discontinued in 2010, this 120 x 194 x 155 mm / 10 heatpipes / 1155 g titan is greatly missed.
