Design and Installation


As mentioned on the previous page, the Ninja 4's square heatsink design (effectively a composite of four smaller towers connected in the center) allows the fan to be attached on any side, which makes it easy to direct airflow even after installation.

While a similar overall size to Noctua's NH-D14 cooler (a dual-tower design), the Ninja 4 offers a lot of fin surface area to help keep your processor cool. Just how well a single fan (and a low-RPM fan at that) can cope with thermals remains to be seen, but the heatsink certainly looks like it can do the job.

The heatsink features six nickel-plated copper heatpipes

The all-important base looks precisely milled and is very flat, allowing for a reliable connection to the CPU.

And now a look at the finished product with fan attached:

The fan's speed controller is located on one side side of the frame


The Ninja 4 is equipped with Scythe's HPMS (Hyper Precision Mounting System), and with this the installation process begins with the fitting of the retention bracket. For my Intel processor this begins with a metal backplate which sits over the LGA socket's bottom plate.

After lining up the holes retention screws are affixed to the top side around the socket.

A pair of brackets are connected on the top side with four screws, and now the Ninja 4 is ready to be attached. As large as this cooler is, the long screwdriver included is greatly appreciated, and this step was easy.

A secure connection with the screws in place on both sides

There is enough clearance to make installation simple, and standard memory modules will pose no issue. Those with very tall memory heatsinks will have to use the outer DIMM slots, and some modules may not work at all.

With the Ninja 4 making secure contact with the test system's Core i5 processor, it was time to test out the temps and noise.
