Motherboard mounting hole DIAMETER

What's the diameter of the holes on the mobo? And/or how big should I drill the holes in the block?

Also, do you think if I make the block 3-1/2" wide that might be too big (and hit mobo components)? The reason it will be 3-1/2 is I don't see any other way to fit all 3 barbs on there.

I use #6-32 machine screws to mount my waterblocks. Epox boards tend to have small holes, whereas Soyo boards have huge mounting holes. I don't think anybody pays attention to the AMD specs anymore.

It is possible to fit 3 barbs on a 2x3 WB, I do it all the time. It's much easier to do with 1/4NPT barbs than 3/8 NPT. If you have room for a 3.5" WB on your board, go for it. If you still need help, let me know.

wharlst we are on the subject do you know the spacing of these holes i have lost the mesurements i took and i dont want to strip down my system to mesure them again.

ps. im also looking for dimentions for the whole gforce + radeon range.
post or pm. me if you have them

thanx

I usually put 3/16inch holes in my waterblocks for the mounting,

the holes in my epox are a little less than 3/16 and looks like 4mm.

thanx for them

what about for amd cpu

36x66mm or 1.42x2.6in
