what is the ideal cold plate thickness on a copper waterblock.... thick or ultra thin ?

I have an all copper water block (an oldy but a goody) and i'm wondering how thin I can get the coldplate side so's to get the water closer to the cpu. I'm aware the water is to cool the copper is to cool cpu and the plate has to be of reasonable thickness. It is a little over 2 mm now but wonder if I get a result if machined to 1 mm .
Like most that want to oc an Ivy, I too am grabbing at tweaks I can do to cool it's warmth.
Any help or advice will be very much appreciated.

thanks

Well, I don't know how the design of your block is, but I'd be really worried about the copper flexing and bending, since most of the bracket pressure is concentrated on the edges.

a nonrigid copper block will also eventually start to leak.

thanx Kev
Yer , i'm a bit worried about flex too. I think it's probably best not to go less than 2mm, and just get it lapped to the IHS. (maybe skim a bit off the IHS if I delid it to replace intel TIM with some metal tim, then relid it)
Thanx for your time . I just thought there may have been a (don't bother getting it too thin) perfect depth of plate smile.gif
cheers

I agree with the above.
I wouldn't take too much off the IHS though, same issue if too thin could flex and damage the die. Just a nice mirror finish lap on both IHS & water block. C u on the track later ;-))
