Cogage Arrow

We have already tested one cooler from Cogage, a daughter brand of Thermalright Inc., and now we will discuss the Arrow model. This cooler is supplied in a rather large cardboard box with a picture of the product on the face side and a list of its features and specs on the other sides.

  

In the box you will find three sets of fasteners for LGA775/1156/1366 mainboards, wire braces for fans, The Chill Factor thermal grease, a key with screws, a sticker, and three installation guides.

One glance at the photo on the cooler’s box is enough to realize that the Cogage Arrow is nothing else but a tuned Thermalright IFX-14. Any doubts you might have about that will vanish as soon as you take the thing out of the box.

 

 

What has been affected by the tuning? Not much, actually. The shape of the heatsink plates has been changed. There are now two plates (one in each section) more than in the Thermalright IFX-14 for a total of 110 (55x2) plates. Their thickness has increased from 0.25 to 0.35-0.4 millimeters and the distance between the fins has increased from 1.5 to 1.8-1.9 millimeters. The two sections are placed 38 millimeters apart. The plates are still press-fitted on four nickel-plated copper heat pipes, 8 millimeters in diameter, which are soldered to a copper base, coated with a thin layer of nickel alloy. No other changes have been found in the Cogage Arrow in comparison with the Thermalright IFX-14.

The cooler’s base is convex, as in almost all products from Thermalright.

This is proved by the irregular footprint on the CPU’s heat-spreader:

As opposed to the Thermalright IFX-14, the Cogage Arrow is shipped with a cute 120x120x25mm fan.

 

The fan speed is PWM-controlled in a range of 1000 to 1800 RPM. Unfortunately, the fan’s specs do not list its noise level, airflow and static pressure. The service life of its bearing is not indicated, either. But judging by the marking, it is an ordinary slide bearing with a typical service life of 30,000 hours. The rotor’s diameter is 40 millimeters; the cable is 405 millimeters long.

The included fan can be fastened between the heatsink sections by means of two wire brackets. It contacts the heatsink through vibration-absorbing strips.

There are as many as six wire brackets in the Cogage Arrow kit. Two of them are designed in such a way as to be used with either 120mm or 140mm fans. The cooler is installed on a CPU in the same way as the Thermalright IFX-14 except that it has fasteners for LGA1156 mainboards. The Cogage Arrow is not compatible with AMD processors.

The installation guide and the official Cogage website do not indicate the best way to orient the cooler on a CPU and inside a system case but Thermalright’s specialists suggest that the Arrow is going to be the most effective if its pipes are parallel to the graphics card (or perpendicular to the system memory modules). We tested the cooler in both positions:

 

And we found out that the cooler had a small advantage (1.5-2C°) if installed as recommended by Thermalright (as in the left photo). But considering the convex base and the system fan available in our testbed, we guess this difference won’t show up in all configurations.

The Cogage Arrow is manufactured in Taiwan and comes at a recommended retail price of $65.
