CoolerMaster Jet 7 HeatSink Review

Cooler Master's Jet 7  is one of the most unique looking heat sinks I have ever seen in the heat sink industry.  They have taken the blower fan from their previous Aero 7 series and modified it.  It is now part of their Premium Line of products. With the modifications in place, the new fan looks like an aircraft engine that blinks and lights up with the help of LED's on both ends of the fan.   The heat sink is now a mix of copper and aluminum.  The fins are aluminum and the base is all copper.  This has been proven to be an effective way to dissipate heat, and processor manufacturers have been that combination with their recent processors.

Here are some specifications from the Cooler Master website:

Here is everything that is included in the box.  There is the multilingual installation guide that assists you in installing this heatsink correctly,  some screws for the 3 1/2 drive bay speed control, speed control dial, case badge, 3 1/2 drive bay speed control mount, PCI slot speed control, some thermal paste, and the heatsink itself.

As you can see, the front and side of the blower fan looks just like a jet engine.  There is a white LED on the front of the fan (see arrow) that blinks when the heatsink is in operation. 

On the back, it also looks like a jet engines exhaust.  There is a red LED on the back of the fan that stays lit.

From the bottom, you can see that the fins are pretty dense.  This will offer great cooling.  You can see where the aluminum fins meet the all copper bottom of the heatsink.

As you can see in the pictures below, Cooler Master did a fairly decent job on the polishing of the bottom part.  Although not as good as their HCC-001 heat pipe heatsink.

For the testing of this heatsink, I used the following system configuration:

-AMD Duron 1.6GHz @ 2.33GHz, 1.775v with Arctic Silver 3 compound

-ABIT NF7-S nForce2 Ultra 400 Motherboard

-512MB Corsair XMS PC3200 Memory

-Chieftec Case

-Generic 350W PSU

As you can see, the Cooler Master Jet 7 performs very well when the blower fan is set to a high speed of 3000 rpm.  At this speed, the fan emits an audible high pitched sound, which can be annoying.  At medium speed, which is around 2400rpm, the cooler still performs well, keeping temperatures in the acceptable range. At 1500rpm, the lowest speed, the temperatures are higher, but still moderate.

Overall, the performance of this heatsink is great.  With the same great performance of the Aero 7 cooler, this is a worthy heatsink to purchase.  The Jet engine design looks great in a case with a window, with the lights that are built in adding more effect. 

Techaddicts would like to give the Cooler Master Jet 7 an 8 out of 10 for its stunning looks and good performance.

An award is presented for the visual innovation of this heatsink.  A great improvement from the Aero 7 cooler.
