Lining up for the following shot from left to right – Prolimatech Megahalems Rev. B, Thermalright Venomous X, and the Thermalright Ultra-120 Extreme.
The Megahalems sports a straight row of heatpipes, while the Venomous X has them in an alternate position arrangement. The Ultra-120 Extreme hmm.. I don’t know how I should describe that.
While these three tower heatsinks are of about the same height, the Prolimatech Megalems is the thickest of them all.
Between the Venomous X and the Ultra-120 Extreme, both heatsinks have about the same thickeness when measured from its sides. However, the Venomous X utimately has more cooling surface area, as the fins of the latter actually arc inwards towards the centre.
Also, from this angle, we’re able to have another look at the different heatpipe arrangements adopted by both companies for their heatsinks.
Here’s a top shot of the Prolimatech Megahalems and the Thermalright Venomous X. Prolimatech has a simple design on the top of its Megahalems, while Thermalright sticks to its tradition of keeping things clean.
The Megahalems has a gap down the middle of its fins array, possibly designed as such to reduce air resistance and allow more air through for quicker heat dissipation. The Venomous X on the other hand sticks to the more conventional ‘closed design’.
The Venomous X has a special bent winglet design which serves two purposes, one is to guide air through the fins efficiently, and second to push some air downwards to the motherboard’s PWM area. Cooling the processor alone will never get you a stable overclock if the circuitry delivering power to it is overheating.
Also to note is that the fins of the Venomous X (on the left) are spaced slightly further apart than the Ultra-120 Extreme.
Lastly, the Venomous X feels very solid. It is built to the typical high standards that we all know Thermalright is capable of producing. Every single contact point is soldered, and the base has no gaps at all.
Just for fun, we tried twisting the Venomous X a little. It was an oddly satisfying feeling we got when the heatsink refused our destructive actions.
