PRODUCT PICTORIAL AND WALKTHROUGH
The base does not have a mirror finish but is smooth enough to ensure good conductivity. You will also notice that the base has lines through it. The aluminum fins are sandwiched between copper blocks and then the base is milled down to make it smooth and flat. This ensures that the fins are making optimum contact with both the copper block and the CPU. This is a very interesting idea and looks promising, read on to see how it performed.
The three Heatpipes run through the block and the fins to further improve thermal conductivity. In all honesty I think the Heatpipes are overkill but, better overkill than too little.
Here you can see the backing plate. An advantage of making this cooler specifically for Intel CPUs is that they were able to make small raised locators that fit into the holes in the motherboard. This should make installing the cooler a little less difficult.
PRODUCT INSTALLATION AND TESTING
I tested the cooler against Intel's stock cooler and the Antazone AS-C1000 I reviewed previously. The Intel 805 D I use is one seriously hot running CPU and as a result is ideal for cooler testing. Testing specifications as follows:
CPU - Intel Pentium D 805 socket 775 (stock)
Motherboard - ASUS P5N-E SLI
RAM - 2gb Corsair XMS2 6400 (2 x 1024mb)
GFX - 256mb ASUS EN8600GT
HDD1 - 200gb SATA Seagate Barracuda
HDD2 - 60gb Maxtor IDE
Optical - Aopen +/- DVD/RW
PSU - 750w Xspice Croon BF 700
Case - Generic no name windowed case with all fans removed
In stark contrast to the AS-C1000 the Dual Contact Hybrid Base CPU cooler was a breeze to install and once installed felt sturdy. The locators on the base plate really did help make the installation painless. The installation requires you to remover the motherboard but that is the case with most aftermarket coolers for this format. The thermal compound provided is brownish in color due to its 20% metal oxide composition.
On to the testing
Testing was conducted using looping CPU tests from 3dmark 2006, all coolers were tested in the same configuration and under the same conditions (25C ambient temperature). Idle temperatures were recorded after a 1-hour cool down period and load temps were taken after 30 minutes of 100% usage of both CPU cores. No fans were assisting in the coolers performance other than the PSU extractor fan. Please note, results will vary from configuration to configuration.
The results speak for themselves. This is by far the best set of results I have seen on this system. With a 7C improvement over the stock cooler you really can't go wrong. The fan is fairly loud at full speed but given that it performs so well I easily managed to find a good balance between volume and cooling using the provided fan controller.
