    Each HDT cooler comes packaged in a nice retail box with a front window with the cooler specifications on the rear, and on the side panel is a list of the CPU's it will work on. Also, each box is sealed with a tamper proof sticker.

    The RVT-12025 and RVT12025D are essentially the same cooler, just one is a tower style while the D model is horizontal. With that said, let's start off with the Revolution RVT-12025 H.D.T. CPU cooler. Like I said a sentence ago, the RVT-12025 is a tower style cooler which will fit in most desktop enclosures. The base of the cooler is set up in reverse compared to a standard heatpipe cooler. The base is made from aluminum and has three channels cut into it. Those three channels each hold a heatpipe, but here is the kicker. The heatpipes are actually part of the base that makes contact with the CPU. Hence, the Heatpipe Direct Touch, or H.D.T. The heatpipes have been flatten and everything is on a smooth plane.

    The three heatpipes are bent into a U shape, thus giving a total of six vertical pipes. The heatpipes pass through an array of 54 aluminum fins. On the face of the fin array is an 120mm fan, which is secured to the fins with a rubber mounting system. The rubber will reduce any vibrations and noise from the fan being passed to the fins. The fan uses a 4pin connection, and a 4pin to Molex adapter is also included. Lastly, an aluminum spoiler or wind deflector is included to help direct airflow over additional components. This concludes the RVT-12025 overview.

    Now it's time for the RVT-12025D, which is part of the H.D.T. line of coolers. The aluminum base on this cooler has four channels cut into it for each of the heatpipes. The heatpipes on the RVT-12025D model are slightly smaller in diameter than those on the 12025, thus allowing for the additional heatpipe. The RVT-12025D is a horizontal, unlike the 12025 which is a vertical tower style cooler. The four heatpipes pass through 59 aluminum fins. On top of the fins is an 120mm fan that blows cool air down over the fans and the components on the motherboard. The same rubber clips are used to reduce vibration and noise.

    Each of the Revolution H.D.T. coolers use the same mounting hardware for the AMD CPU's, so this will apply to both units. The first step in the installation is getting the correct mounting clip for the CPU. For AMD users, the clip system is used and the clip just sits in a groove on top of the base. For the Intel CPU, the four corner, push-in clip system is used. The clip is a two-piece unit that gets fastened to the cooler with two screws. Also included is some thermal grease. Usually thermal grease is applied to the CPU, but with the bases of the H.D.T. coolers having slight gaps between base and heatpipe, it's necessary to put the thermal grease on the cooler to fill those gaps. After that is done, install the cooler.

Testing:

    For testing, BurnInTest Ver4.0 and Prime95 was used, running a total of three tests in a sequence of ON for one hour at 100% CPU load, then OFF for 30 minutes to cool. The temps are collected and an average temp is calculated.

TEST GEAR:

• ASUS P5E3 Deluxe WiFi-AP@n

• Intel Core 2 Duo E6850 (3.0GHz)

• Kingston 2GB DDR3 PC3 13000 CL7 RAM

• Sapphire HD2600XT Graphics card

• WD 80GB SATA II HDD

• Samsung Super WriteMaster SATA DVD+R DL

• KWI Absolute Power ABT-600CW Power Supply

Conclusion:

    As you can see in the results, the Revolution H.D.T. coolers performed almost identically to each other. That was expected because essentially they are the same. The only real difference is the shape. One thing that really pleased me about these coolers was the fans. Not only are they extremely quiet, but there are also NO ANNOYING LED'S. I like my LED's, but not on every device I have in the enclosure.

    The overall designs for the H.D.T. coolers are great. The install on the RVT-12025D model was easier than the RVT-12025. This was due to a tight clearance issue with my fingers pushing down on the pins for the Intel install. On a positive note, the motherboard removal was not necessary, and that is another major plus in my book for CPU cooler installs. With that said, both H.D.T coolers performed well, both are damn near silent, and the option of either a tower or low profile unit is another plus. I would like to thank Kingwin for sending out these coolers for VH to review.
