MODTHEBOX would like to thank Lori Lee from CoolJag for sending the CoolJag JAC663A CPU Cooler for review.

Introduction:

In 1986, Chia Cherne started out making bicycle components like brake and derailleur cables and has since become one of the world’s leaders in Cycling Components under the name Jagwire. In a totally unrelated move, Chia Cherne founded Cooljag in 1999, as a new player into the CPU heatsink market utilizing the latest "Skiving" technology to achieve greater thermal cooling with a high-density fin design. Cooljag has an extensive line of heatsinks for most CPU applications or preference in noise and size. Today in the MTB labs, we are taking a look at the JAC663A, a heatsink designed for a more quiet cooling performance.

Specifications:

The JAC663A follows the design of most standard coolers on the market by using an aluminum base instead of copper. The JAC663A is being marketed as the cooler for ethuiasts who want quiet system performance cooling. Here are some specifications from CoolJag’s website:

The cooler ships in a corrugated cardboard box and sports the CoolJag Logo. A white sticker on the side panel identifies the model of CPU cooler, and the processors it is rated for. Included with the heatsink are an instruction manual and a packet of generic thermal compound.

CoolJag JAC663A 3-pin connector

 

The sides of the JAC663a is constructed of solid aluminum sides or shrouds. This type of construction helps direct airflow out the open sides with the air flowing across the heatsink and out the power supply. The power is supplied through a three-pin connector that is to be plugged into the corresponding motherboard header clip.
