HI.
Maybe dis Thread can help you a little bit.

I have an Asus P4P800 Deluxe.
The conclusion is, that you better buy the parts to complete your old Twinplex to a "Twinplex CP4 Typ3".
So you need "Blende and Deckel with 4 Halteklammern and 4 Federn".
The Typ3 fits the Board better than Typ1 (4 !! Fixing-Points vs. 2 Fixing-Points).
But the Typ3 has only a very small Problem with one Electronic Device (Condensator) on the left side near the Northbridge.
You must prepare the "Deckel" with a small hole. I used a small Drill for that. (Dremel)
Nevertheless the Typ3 is the better and best Choice.
I think Typ2 will definitely not fit.
So you can choice between TYp1= No manual fitting, but no perfect fit and medium cooling
or
Typ3= Very small manual fitting and superb cooling.
Look in the Trhead above, there are some Pictures from my solution with Typ3.
Sorry for my English, I'm a little bit drunken....
