Scythe Ninja 3 Rev.B High Performance CPU Cooler

Scythe’s best-selling flagship cooler is now in its third iteration. The Ninja 3 has improved performance and can be used without a fan for cooling in absolute silence.

The third edition of the Ninja CPU cooler comes with a revised high-performance design. The Ninja 3 CPU cooler has eight U-shaped heat pipes and an optimised fin structure called M.A.P.S. (Multiple Airflow Pass-Through Structure). The airflow generated by the included Scythe Slip Stream 120 PWM Adjustable fan can effectively cool the heatsink.

Features

  1. New and improved Ninja!
  2. Utilises eight “U-shaped” heatpipes
  3. Six-core ready
  4. Supports fanless mode
  5. Supplied with Slipstream 120mm PWM fan for ultimate performance
  6. Compatible with Intel LGA2011/1366/1155/1156/775 and AMD FM1/AM3+/AM3/AM2+/AM2/939/940/754

You can choose between fully automatic PWM fan speed control or alternatively adjust the PWM band range for tuning purposes. Several features make this cooler the perfect solution for silent PC users and overclockers! And finally, the F.M.S.B.2 (Flip Mount Super Back Plate 2) back-plate system provides a totally safe cooler mounting mechanism, guaranteed!

Customer Reviews

Ninja 3 excellent!

,

I installed Ninja 3 and this is a great CPU cooler. Installation required removal of motherboard but instructions were clear, build quality amazing! Core temps on light load of 40C and 37C running on fan with minimum setting of 740rpm. I am even experimenting with fanless operation for light duties - so far no issues! I am puzzled though how to get the lower fan range mentioned starting at 470rpm. Perhaps someone could enlighten me?

Hi Neil - thanks for the review! In order to get the lowest possible speed from the fan you will probably have to adjust the PWM settings of the motherboard either in the BIOS or through utility software usually supplied with the motherboard.

The settings can vary quite a bit but normally you would have three settings like Performance, Optimal and Quiet. You need to set your PWM settings to the quietest settings available in your BIOS and that will reduce the overall power going to the fan enabling slower, quieter speeds.

Hope that helps!

Kind regards, Andy

“Very pleased”

“I am in my 70s and have never been the computer expert by any means. I only got into computers 15 years ago. Delivered very quickly. When I saw the spare bits I was a bit worried. But soon made sense of it all. Set it up beautifully with no problems and now working fine. Only slight problem was one disk did not want to come out of the slot. However, when I switched off and it cooled down and I tried again all work well.”
