Cathar/DTEK Whitewater and C2D E8400...?

I have an old Whitewater (DTEK) which I used on a P4 socket 478. Now I upgraded everything including motherboard to a C2D E8400.

Does anyone have experience of running a Whitewater block on a C2D chip? Firstly can it be mounted correctly and secondly how does it perform (since there are two cores and not one in the center like with the P4?)

I tried to mount my old DD RBX (Whitewater knockoff/ripoff) on a Gigabyte board a year or so ago and I found the old block was just too wide to mount on the board. It had hard contact with the ferrite chokes and capacitors around the socket area. I imagine that if it fits into the socket area it would work decently.

Mobo is ASUS P5QL-E I'm not sure how that compares, if it's any help! Same problem? Would be nice to get some feedback before taking everything apart

It's so hard to say about the Mobo. The caps arent's as close as some other mobos. From what I remember the caps are much closer than the P4 days and taller, or seems to be.

Can you measure the length and width of the CPU block?

Just as a gestemate, looking at your mobo pics and my mobo (in my sig) I think your mobo caps are 1.6-1.8" from center of the CPU. So measure your block.

Hope it helps.

I got round to removing the heatsink because I'm installing a different CPU. Unfortunately the whitewater won't fit because of the capacitors, no matter which way I rotate it

Yeah, sounds like you ran into the same problem I did with the RBX. Those old block designs are just too wide for today's motherboards, unfortunately.
