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 - Closer Look and Installation

Scythe Ninja CU : Closer Look

There’s no mistaken what material is used for the Scythe Ninja CU, all photos have a nice red glow to it, the Ninja CU is a copy of the Ninja Rev B, but with copper fins instead of aluminum fins.

The build quality is excellent and we couldn’t find any faults:

The heatpipes are spread out evenly at each side of the Ninja CU:

The base is flat and polished almost to perfection:

Installation

You can install up to four 120mm fans if you have enough fan clips, the metal clips are held in place by sliding them in the cutouts of the copper fins:

The low speed fan included is a Scythe model SY1225SL12L , this fan has more blades than the average 120mm model, but they are thinner:

Installation of the heatsink on the motherboard requires you to first install the correct bracket on the heatsink:

For S775 you install a custom bracket on the motherboard and use the included back plate for extra strength supporting the weight of the Ninja Copper. Installation requires motherboard removal and takes a good 5~10 minutes, taking care of mounting the brackets on the motherboard, when that’s done it’s a matter of clipping the Ninja in place.

For our passive CPU cooler tests we included results where we placed two cardboard cutouts at the top and bottom of the heatsink, creating a duct, this mods takes 2 minutes to implement and has proven successful in the past.

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.
