There are six copper based (nickel plated) heatpipes of which three are arranged in a U-shape design, the other three are a bit twisted away from U-shaped heatpipes. Additional holes in the fins are there for more efficient ventilation.
When we flip it around (plastic protection covers this) we see an all copper yet nickel plated base.
Not exactly a 100% mirror flat finish, there's room for some improvement, though it's real flat and good. Bear in mind, the kit as tested supports Intel socket LGA 1366 / 1156 and 775 only.
Thermalright HR-02 CPU cooler review We test and review the Thermalright HR-02 CPU cooler. Thermalright actually introduces this product as a passive CPU Cooler. The HR-02 is the second revision of the legacy Thermalright HR-01 cooler. We'll test it passively cooled yet we'll also pair it with Thermalright's TY-140 fan, a 1300 RPM fan that is silent, yet high performing. As stated, the results stunned me, this is really really good stuff.
Thermalright Venomous-X review We review the Thermalright Venomous-X CPU cooler. A cooler with great looks, excellent performance and some very clever innovations. A cooler that is compatible with Intel LGA sockets 775, 1156, and 1366. The cooler is ready for the upcoming Nehalem Gulftown based processors (six-core) and also comes with something new, called the 'Pressure Vault Bracket', allowing you to decide how much pressure the cooler should have on top of that expensive processor of yours.
