A Closer Look

The Kingwin HDT-12025 is the 120mm model that is configured perpendicular to the motherboard. I have been using coolers configured this way for quite some time, but this is the first 120mm version I have used. The benefit for using a cooler configured this way is the smaller footprint… it takes up less room in the case, making it easier to get to your motherboard jumpers and buses, memory, etc. The drawback is that the cooling air is blown towards the rear fan, lending little or no cooling to the capacitors and mosfets on your motherboard. Included with the 12025 is a “spoiler” that directs some air towards the motherboard. We'll look at it during the installation phase. Also, a 120mm cooler configured this way puts a lot of stress on the motherboard, and the LGA775 mounting pins if using them. The Kingwin cooler is lighter than most 120mm coolers on the market, so hopefully that won't be an issue. Additionally, the radiator will be fairly close to the case side panel, which may interfere with any fans, ducts, etc, that may be there.

The fan is a standard 120mm x 25mm 4-pin PWM fan. There are three heatpipes, each running through the radiator twice. The fins are like the ones on the 92mm version, somewhat thicker than other brands I have had. They are buffed brushed aluminum and quite shiny. The fan is attached by these rubber shockmount pins. They are pretty simple, but hold the fan tightly against the radiator. Removal of the fan is a little scary with these - you stretch the pin until the barb is small enough to go through the screw hole, to the point that you get a little afraid that they will break. They eventually do.

On other coolers of this type, I have found that removing the fan makes installation much easier with the push-pin LGA775 motherboard mounts.

Here is the base of the RVT-12025. As I mentioned, the base is a little smaller than others, cutting down on weight. The base and heatpipe surfaces are far from lapped, but as shiny as many coolers I've seen.

Notice that there are small gaps between the base and the heatpipes. Special consideration needs to be given when you are using a thermal compound that is intended to be spread by the base surface, such as Arctic Silver 5. Since the surface is not flat, AS5 cannot be used as per the manufacturer's instructions. Before, I spread the compound thinly on the heatspreader surface, and it worked great.
