Design and Functionality

When you see Venomous X for the first time, it immediately reminds you of Thermalright Ultra-120 eXtreme. True, Venomous X heatsink is barely different from that of the predecessor:


The new heatsink is 5 mm shorter and 1 mm smaller: now it measures 127 x 63 x 160 mm and weighs 755 g instead of 790 g by Ultra-120 eXtreme. The cooler is still composed of six copper nickel-plated heatpipes 6 mm in diameter that hold aluminum heatsink plates:


Venomous X has 1 plate less compared with Thermalright Ultra-120 eXtreme rev.C. The gap between the plates is a little smaller than by Thermalright Ultra-120 eXtreme rev.C (1.9 mm vs 2.0 mm), but still a little bigger than by the old Thermalright Ultra-120 eXtreme, which plates were spaced out at 1.8 mm from one another. The plates are 0.5 mm thick.

Although the heatsink of Venomous X cooler is shorter and have one plate less, its effective surface area has hardly been affected, because it is of almost rectangular shape, while the Ultra-120 eXtreme heatsink was curved inwards. The heatpipes inside the heatsink are shifted in a little different way than by Ultra-120 eXtreme. The latter had its heatpipes arranged in an oval-shaped pattern. The new Venomous X cooler has its heatpipes lined up in two precise rows (three in each) that are shifted away from one another:


The heatpipes and heatsink plates are soldered together. The heatpipes are also soldered to the grooves in the cooler base plate. The thinnest part of the base plate below the heatpipe measures 2 mm:

The base of the new Venomous X is finished in a completely uncommon way for the solutions from this maker: it is polished to mirror shine:

However, the evenness is still the same - with a bump in the center – which is a typical distinguishing feature of all Thermalright coolers:


As a result, the imprint of the processor heat-spreader on the cooler base shows a clear emphasis on the central part:

Although Thermalright have been constantly protecting this bump claiming it is a “constructive peculiarity” of their cooling solutions, we still believe that ideally even base surface is way more efficient than the mirror-shining finish. Unless the heat-spreader of your CPU has a concavity in the center shaped exactly as the bump on the base of your cooler :)
