Hum... this is going around in circles!

IMO, the groove for an o-ring is the best option, but I will have to consider a silicone sealer. Here's why:

Water will respond very nicely to an o-ring, without a silicone sealer. In my rig, phase 1 is a straight watercooler, in it's simplest form. Phase 2 involves adding a TEC. Phase 3 adds a water chiller. When I go to phase 3, I'll be using a water/methanol mixture.

With methanol, an o-ring doesn't work as well, because the liquid is so thin, that it will easily bypass the o-ring.


Dix Dogfight: I'm gonna refer you to the link to Paul Vodrazka's info (see previous post). The compression on the o-ring is minimal. The fin pattern is flush with the top of the bottom piece of this block, so everything should clamp down nicely with a flat top.

Got an e-mail from Utabintarbo this morning. I think I passed my paranoia to him! The copper top might become a requirement, so unless myv65 can point us to a mechanical link, and I can calculate that the plexi/acrylic top is viable, it's gonna have to be copper :shrug: .

Going over AMD specs, it seems that the four corner bolt isn't appropriate (flash!). It looks like the mounting pressure must be applied longitudinally across the core. I don't get it though, what keeps the block from tipping in the other direction, crushing the core? The little pads? Are they soft rubber, or do they have any kind of solidity to them?

Here's a pic (not for Radius).

In this configuration, we could add tabs to the sides of the block.
