One thing Helios is that in your review the difference between the VX and Mega is the greatest I have seen. Especially as the TRUE is beating the Mega. Thought the Mega only performed a couple of degrees worse than the VX?
VX is the best cooler you can buy new at the moment without spending £120+
Ended up getting a good deal on a megahalem.
My supplier was out of stock on VX
The Noctua NH-D14 is slightly better.
that's very debatable from all the reviews I've read, some get better with the venomous X, others get better with the D14, although iirc the VX does better than the D14 when higher voltages are used
