The third and fourth coolers hail from Thermalright, known for their XP-90 and XP-120 CPU heat sinks, each of which enjoyed being one of the best air-coolers, upon release. Their newest line of chipset cooler features two models, the HR-05 High Riser and the HR-05 SLI High Riser. To meet their name these coolers have a heat pipe attached to a 77x77mm radiator, and a nickel-plated copper base.

Upon opening the box I was greeted by one of the most carefully packaged heat sinks ever…it made such an impact on me that I had to make mention of it here. Carefully nestled in the foam are the clips to attach the heat sink, a rather large tube of thermal paste, a couple of push pins, a Thermalright sticker, mounting instructions, and the heat sink itself, in a rather heavy plastic bag.

The HR-05 weighs in at 145grams, a wee bit lighter than the Thermaltake cooler, and measures 77.9 x W19 (fin), W30 (base) x H105 (mm), without fan. The HR-05 SLI weighs 124grams and measures L78xW19 (Fin), W62.5 (Include body) xH105mm.

Looking at the base, the entire image of the ZALMAN sticker is obscured. The fine mill marks left by the lapping process seems further “enhanced” by the nickel plating. Yes folks, that’s a copper base with a coating!
Taking a look at the HR-05 SLI, we can easily see the differences between the two chipset coolers…most obvious is that the SLI model uses 2 heat pipes instead of one. Will this affect cooling? Let’s take a look at the unit first!

The SLI model uses a slightly different base than the non-SLI model as you can see in the picture; however this one is nickel-plated copper as well. The pipes do not cover the middle of the heat sink, instead are slightly away from the mid-point. On its sister model, the heat pipe goes directly through the middle of the block…in one side and out the other. So, other than the use of a second heat pipe, and the “radiator” being slightly offset from the top, these units are identical.
