And I will check those other threads.

I got a Duron 700 sitting right here.
Testing it will give usless data to modern CPU's as they are not made the same but at least it is a cheap CPU. The hard part is creating a water proof seal between the metal die and the CPU body. This will be near impossible as the CPU die with expand andcontract differetly from the temperature that the CPU body. How much I do not knw as I have no clue what the thermal properties of the CPU body material is.:shrug: BUT if you use some type of silicone that will flex a little it may work up till the core errodes.
Remember there is not much room under the surface of the core before it is toast.
Direct die is certainly not reliable, hell plain water cooling with a water block is not even all that reliable yet. Still see quite a few failures in the forums. Mostly due to the user, but with direct die there is a lot less room for error. If the pump shut off the thermal protection may not act fast enough. Also the pump MUST be running BEFORE the power switch is hit on the computer. I do not think it would be wise to have a relay that turns the pump on at the same time. I fried a CPU in about a second once.
Always unplug/shutoff the damn power supply when removing a HS/WB in case you acidentally hit the power switch!!! Not one of my better moments. But if that water fails to circulate fast enough the core will heat up rapidy. Maybe not toasting it but it maybe enough to break the seal.
Tuff challenge. I think more work from the CPU manufactuer would be needed to make it work reliably. Which I doubt is in their best intrest right now.
