Well I hooked up the Venomous X today. I luv the new retention system and they've modified how the fan clips attach to the heatsink so they stay attached better. Both are excellent improvements. The base of the heatsink is slightly flatter and it comes with a beautiful polished finished.
Straight out of the box, at my standard overclock of 4.2GHz LinX would not run. It crashed almost immediately and I was unable to capture a screenshot. And it's cold inside today, it's 65F and no heater is running. This is easily 5-10 degrees cooler than normal.
My next step was to lap the base until it was Flat and I went ahead and made sure it had a polished finish.
With the base lapped flat and my standard overclock of 4.2GHz applied I was able to to capture a screenshot of LinX. After 1 minute my system is hotter than it's ever been (not counting the unlapped run above).
I'm going to test the Venomous X against the standard True I have in my Office Workstation this weekend. I don't have a good feeling about this heatsink, I think the standard True will defeat it also. The biggest problem I see with this heatsink is the new Fin Spacing. The distance between the Fins has been increased, how did they do this? They used fewer fins which amounts to less surface area for heat dissipation under heavy load. At an Idle the Venomous X is able to match the True Copper for cooling ability. But under a Full load, it just can't get rid of the heat like a bunch of Copper fins can.
I took a bunch of pictures that I'll be posting in a Lapping Thread
And I'll be taking a few more pictures this weekend to illustrate some of my opinions above
