What is the most important in above specifications is that the Ninja 5 works on nearly every modern CPU socket, excluding AMD Threadripper which simply requires much larger cooler base. We can also see that the Scythe Kaze Flex fans run up to 800 RPM what is quite low speed but still offer high performance. Of course, we will check that in our tests.


Product Photos and Package Content

The package is not much different to what we are used to seeing in other Scythe coolers. Black box with well-described contents looks pretty nice. We know all that we need without opening the box but the most important is of course inside.

Inside the box, we will find large cooler, two Kaze Flex fans and a small box of additional parts and tools. Scythe added everything we may need to install our new cooler so we don’t have to worry about the screwdriver, thermal grease or mounting elements for fans. Everything just perfect.

Big tower design of the Ninja 5 cooler is based on six large heat pipes which are covering the nearly whole base. The base itself is made of nickel-plated copper. It’s about the best option on the market right now and I don’t think it will change anytime soon. The base is also well polished – nearly mirror effect. We are used to seeing the same in other Scythe coolers.

The Kaze Flex fans look great and work great. These are one of the best fans we can find on the market. Provide high air pressure and low noise. Fans speed can be controlled between 300 and 800 RPM.

Installation of the Ninja 5 is quite simple and if you follow instructions in the user’s manual then you will be fine. The whole installation takes less than 5 minutes. Above you can see example photos of our cooler installed on ASRock X299 Extreme4 motherboard. The used memory kit is Ballistix Elite which is quite tall and as you see, there are no issues with Ninja 5 installation. It doesn’t change fact that the cooler is huge so check twice if you can install it in your PC case. Most gaming PC cases should be large enough and support this cooler without issues.
