If its any help, I got a fair load of those Vantec Copper jobs from OCUK...
They fit in most of my Mobos...
MSI Neo2 & Neo4
DFI LanParty
Abit NF7 & NF7S
Couple of others too!
Although on the Neo4-f It has gone on just fine, the previous GFX Card ( ATI X1600Pro ) was a VERY TIGHT fit and the card, when pushed firmly down, also toppled the cooler and so it was not a good fit.... This is due to the position of the cooler vs the PCIE slot more than anything. Its been replaced with a 6800GT and its fine.
No, there is no speed wire, however, I have to say, that I have all the above boards and a few others ( Mostly non clockers Ill admit ) and not one of them can I actually hear the cooler spinning up, and in the case of the NF7S its allowed me to clock both my XP1700 and the XP2500 morereliably than I was able to with any other "Supposedly good" cooler?
I would actually say that they are among the most underated coolers out there! - the other junk you get with them however, is good for nothing... I have just taken a pile of them and cooled the bottom of an old Radeon 9800's RAM Chips, and that was only to avoid throwing them away.
