How thick base for a rotor style block?

[max]

2mm = too thin
3mm = better

Do you people think 4mm would be better than 3mm?

I would just try it but i am running out of copper

3 to 4 mm should do you just fin..... how thick is the copper you are going to use?

If the base is too thick...the water will not be able to pull the heat off the copper efficiently.

The idea is for the Higher temps to reach the water and be removed.

For example..the thinner the wall is the shorter the distance the heat travels to the water...the quicker it is removed...Thus more heat is removed.

The thicker the wall..the less amount of heat will make it to the water to be removed..thus making the waterblock hotter and the cpu hotter.

The heat will only penetrate so far into the water block...if that helps you???

Thanks my copper is 12mm thick flatbar.

Tuff has a valid point.... but it's all about balance.... concentrating all the heat in a very small area of the block, will yield a higher Delta T, which is good, but it's at the cost of much reduced surface area.... This, with water-cooling is not so noticeable,as it would have been with air, due to the fact that Water is much better at absorbing heat. nun the less, it is still about balance between the surface area and the resultant Temp at the point of transfer. All the heat will still need to get moved through that junction, so no matter which way you go, look at it as a balancing act. I found opting for more surface area, combined with superior turbulence, to yield awesome results, especially when one is "PUMP-IMPAIRED"

If a high pressure direct displacement pump can be used, the micro-chamber approach would be preferable, as one would have the ability to move the required volume through the restriction involved. That combined with the much increased Delta T at the junction should also give exceptional performance.

Hmmmm, i understand what you are saying and its much appreciated thank you.
