I am thinking about getting a watercooling solution. The goal for me is to have a computer that makes no compromises in speed but which is still extremely silent.
Until recently I was going for the usual array of undervolted fans solution that seems to be the norm. But lately I've been thinking about trying the watercooling route instead.
What I'm thinking about is making a system where the CPU, GPU, HDDs and the PSU are all watercooled. For making the PSU fanless, I thought I would just attach a watercooling block to the main PSU heatsink. For cooling the HDDs I was thinking about making a soundproof metal box, in which I could place my HDDs together with some watercooling solution, perhaps something like this
My initial design for the HDD box would be a metal box, completely coated with sound dampening lead mats on both sides, inside of which I would suspend the drives in rubber straps. I have access to a decent metal workshop, so making a box of the right size should not be an issue.
Firstly, do you think a watercooling setup could be used to effectively silence and cool a PSU and HDD as well as the GPU and CPU?
Secondly, do you think that a fanless radiator, either a full size automobile radiator used witout a fan, or a Zalman Reserator would be suited for water->air heat exchange? As far as I can tell, the componernts I have planned for the system (Athlon64 3000+, Decent GPU, dual raid 10K RPM HDDS, PSU) should use somewhere in the neighbourhood of 150W, putting it at the limit of what a Reserator can handle.
