My project settled down som 8 months ago and I haven't been around here any much lately.
Some perhaps valuable experienses have been made:
Having the case act as a heatsink still rocks. Since the Raptor is stuffed into a sound dampened water cooler and the case is internally tapestried with heavy sound panels, the PSU is the noisiest part..
The back-up hdds, a Barracuda V with AAM and a Spinpoint V, are suspended in elastic cords and cooled with aluminium side plates.
Pumps make noise!
My pump is hanging in silicone cords, not touching anything solid. The tubing is silicone too, or the vibrations spread through them. The pump was without doubt the most difficult part shutting up.
The water loop works better if split. In my case, into three different loops, each with better flow now than the original single loop ever had. My 1048 pump can pump quite a lot but is very sensitive to back pressure.
The loop running along the case walls need only a small flow. Clamps solves all flow directioning problems.
My setup featured 2xPapst 4412 rad fans @ 4V, one 92mm Papst intake fan cooling hdds, one Panaflo M1A in Seasonic PSU. This made the internals hot. Added anorther 4412 intake fan in bottom. Fans controlled with an Innovatek Fan-O-Matic, all at really low voltages.
To have the PSU shut up I constructed a duct from the front. Help fans, Papst 8412s, added to help PSU fan. The PSU fan still spinned up after a while. Turns out the air in the duct heated up, actually becoming hotter than the air in the rest of the case. Tried isolate the duct but it's not good enough. The case's warm top striked back, it seems.
Reversed fan in PSU, now a Nexus realsilentcasefan, blowing from the back and then into the isolated channel, out front. Some places in the PSU are not blown on of course but it's quieter. (These temps taken with DD5 thingie.)
Shall now open slots on top of side panels to duct in air to the PSU from there.
Concluded that water cooling has small benefits and I wouldn't recommend anyone to go there now that so good air coolers are available.
I remember taking lots of pictures during the process. Could it be someone is still interested in seeing this? It could take a while but the pics probably still can be found on a server somewhere around here.
