Cooler Master Jet 4

When you overclock your processor, large amounts of additional heat are produced. If you fail to eradicate all this heat from your processor, your computer components are likely to become damaged. The most common way to disperse this heat is via a heatsink. The heatsink we will be looking at in this review is the Cooler Master Jet 4 to see how well it can dissipate heat from your hot Intel Pentium 4 processor.

Features:

One of the major features which set this heatsink apart from many other heatsinks, is its design. This heatsink employs a ‘jet blower’. With the jet blower, air is pushed directly and thoroughly into the center of the heatsink. In addition, with a jet blower there are no “blind spots” on the underside of the fan which can cause a drop in performance. This is a problem commonly found on traditional fans.

Included in this package, is the actual heatsink, mounting brackets, 3.5” cover, PCI cover, knob, screws, manual, and a little pouch of thermal paste. A nice feature of the heatsink is that it retains all the requirements in order to be mounted in the standard Intel Socket 478 retention frame. This means, you will not need to take out your motherboard and install a new frame. The 3.5” and PCI cover are used to mount your fan controller wherever you desire and then pop on the knob, so you can control your CPU fan speed from the front or rear of your computer. Sanchen Chemicals makes the heatsink’s silicone compound thermal paste.

Examination:

Upon looking at the heatsink, I was impressed with the gleaming metal around the jet blower fan. The metal on the front of the heatsink was incredibly shiny. In addition, another obvious aspect you can see from the heatsink is its massive size. 83 x 68 x 50 mm are its dimensions and it weighs in at a hefty 700g. It is quite apparent that Cooler Master decided to go with an airplane type theme when designing the heatsink. All the way from the name, the Jet 4, to the appearance of the fan, an airplane theme has been taken into effect. The front reflective side of the heatsink looks very similar to the front of the engines found on airplanes. On the rear of the heatsink, for its exhaust, it too looks like the exhaust of an airplane. Two LEDs are added to the heatsink, to improve its appearance and to resemble an airplane even more. One of the LEDs located at the top blinks white, while the other is red and is located in the exhaust. I imagine the white blinking LED is to resemble the lights on the wings of airplanes, or the white lights located on both sides of the runway. In addition, the red light on the exhaust, reminds you of heat spewing from the rear of the engine. Overall, the appearance is visually stunning especially if you are into airplanes.

Also, while examining this heatsink immediately after extracting it from the box, we found a problem. Two wires lead from the fan of the jet blower, to a controller so you can adjust the speeds of the fan; however, the one we received was broken. One wire was attached to the controller fine; however, the other wire was attached to a small broken piece of what appeared to be another PCB (Printed Circuit Board) similar to the one on the actual controller. As you probably know, you can’t have a complete circuit unless all of the wires are attached properly, and a wire connected to a broken piece of dead PCB is no way a complete circuit. In order to fix this problem, we simply removed the broken PCB, and with the wire which was connected to that PCB, we pulled out a soldering iron and soldered it onto the proper location of the controller where the wire should have been attached in the beginning. It is unknown if PCToyLand (the suppliers of this heatsink) caused this quandary or rather Cooler Master.
