Scythe Ninja 5 CPU Cooler Review

Admin Cooling 2666


We reviewed the Scythe Ninja 4 a couple of years ago and recommended it. Not hard really, Skythe are an old-school PC cooling and accessory company who have been around since the start of the modern enthusiast’s system building era. Scythe sent the Scythe Ninja 5 CPU Cooler to review and we are more than happy to oblige. 

We are fans and with good reason, Scythe does represent the enthusiasts market and do deliver products that generally support the more interesting solutions. With that said, everyone can produce a bad product now and again, will the Scythe Ninja 5 CPU Cooler deliver?

We have put the specifications for the Scythe Ninja 4 and the Ninja 5 together. This is more than a minor revision, and you would be forgiven for thinking it’s a different product range. The main differences with the Ninja 5 from the previous Ninja 4 is the basic overall size, mainly due to the next difference, the inclusion of a second PWM fan, and fan type. Both included fans are PWM, this is something we feel all fans should be. There isn’t any RGB, but we like that!

Scythe Ninja 5 CPU Cooler

Packaging - 8.2
Performance - 9
Price - 8.5
Consumer Experience - 8.5


The Scythe Ninja 5 is an overclocking CPU Cooler, no doubt about that. If you are not going to overclock, it will help keep your system quiet, even under load, and with two PWM fans, you can create your own fan profiles for extra diversity.
