Passive CPU Coolers ShoutOut: CM Z600 vs Scythe Ninja CU

Cooling/CPU Cooling by jmke @ 2008-05-21

In this comparative performance test we put two 1000gr+ CPU coolers through our stress tests to see which one comes out on top. Both are designed for passive cooling but can benefit from a bit of forced airflow too. How to they compare to the other 40 heatsinks we tested before? Let´s find out

Scythe Ninja Copper - Specs and In the Box

Scythe Ninja CU

The original Scythe Ninja was launched more than 3 years ago, since then Scythe has released several revisions to perfect the manufacturing process and mounting system for the new platforms. The basic design however has remained pretty much the same, a limited series of aluminum fins which are approximately the size of a 120mm fan are held together by no less than six U formed heatpipes; these heatpipes are joined together in a copper base large enough to cover the latest AMD and Intel processors.

At Cebit 2006 Scythe demoed a copper Ninja CPU cooler but we were told that it would not be available in retail due to the increased cost and less than stellar performance improvement over the normal version.

The original version will set you back approximately €35 ( while the new full copper version costs ~€55 (BytesAtWork), that's quite a premium you have to pay; in that regard Scythe was right that the Copper version is not very cost effective. But the public demand was large enough for them to produce a Copper version of the Ninja in larger quantity. Today we’ll find out if its performance is worth the extra cost.

The packaging is quite clear but a bit logo heavy; still it gets the message across of what the product is and what it is capable of.

Yes the Ninja Copper passes the magical 1000 gram weight limit, not a lot of CPU coolers out there even come close to this. The included fan is build for silence with a rotation speed of only 800rpm at 12v your system will be very quiet.

The Scythe Ninja supports all current AMD and Intel platforms (AMD S754,S939,AM2, AM2+ - Intel S478, S775).

For your money you get:

  • Scythe Ninja Copper Cooler with 6 heatpipes
  • Low noise 120mm fan with 3-pin power connector.
  • Detailed installation manual
  • Mounting gear for all platforms
  • A small bag of thermal paste
  • A pair of clips to install the fan onto the heatsink

    We would have loved to see an extra set of clips as the Ninja heatsink has enough mounting points to have multiple fans installed, only thing holding you back is room inside your case. The fan has no PWM support, PWM is quite popular nowadays on both AMD/Intel platforms and allows for better automatic fan speed control through the BIOS. But seeing as the fan is running at only 800rpm at full speed, it would not make much difference.

    Let’s take a closer look at the red beast ->

    Nice review.
    I've got a Ninja CU, but it's a bit difficult to mount 2 fans on it.
    the 'pull' fan touches the cu fins with it's blades...

    For the rest: great heatsink!

    put two strips (cardboard, foam) at each two sides of the fan between fan||heatsink that should clear up the space; shouldn't be much, 1-2mm is enough.
