Construction

The Gelid GX-7 mainly consists of aluminium and nickel coated copper. The base plate is made of solid copper which hasn't been coated with nickel. Furthermore the baseplate has been well lapped/polished and provide a good mirror effect. To transport the heat as efficiently as possible from the CPU there are seven heatpipes which all have a diameter of six millimeters. Altogether there are 45 fins soldered to the heatpipes. As standard the cooler comes equipped with one 120 millimeter PWM fan with blue LED however Gelid provided an additional clamping mechanism if you want to add a second fan to your GX-7.

Design

We did not see any manufacturing mistakes on our sample, and it seems that is has been well made which means that manufacturing is on a high level. It is interesting to see that Gelid decided to not arrange the heatpipes soldered in one row but made a special array with two heatpipes soldered on top of the three middle heatpipes. Doing so, the heat absorption capacity is better and take advantage of all seven heatpipes. They also opted for a V-design for the fins to optimize the airflow.

Fan

Gelid equips the GX-7 with one fan, measuring 120 millimeters in diameter. Featuring PWM acility, this fan is also equiped with four blue LED. The rotation speed of the fan is quite large, from 600 rpm up to 1800 rpm which is quite fast. With an airflow up to 128.6 cubic meters of air per hour and 2.66 mmaq as for the static pressure value for a noise level rated at 26.8 dBA max. Furhtermore this fan has a magnetic bearing which allows the fan to operate almost noiseless at low rotating speeds. Once the fan is dirty you can even disassemble it and wash it with floating water.
