thread on the Apogee review done by Lee "Robotech".
What is most interesting is that we now have some information about how badly the IHS affects temperatures! Testing with the ancient Maze3 on an Athlon64 chip with an IHS shows that it performs nearly as well as a modern Storm WB! That is, within 1C. See
this post by Lee. Quite informative!
Should all watercooling afficianados remove their IHS? What does this mean for future testing? Is it necessary if no one wants to remove their IHS? After all, if even ancient designs perform adequately on IHS equipped CPUs, then new designs have to be awefully bad to even register a difference in on-die temperatures.
