Sorry I missed a couple of earlier post where you specified some stuff.

If I were in your position I would see exactly how much voltage it takes for your CPU to be Orthos stable. You don't need to leave it running for hours, just run it for 20 - 30 minutes and if it clears that your good. That doesn't mean you 100% stable at that speed, but it does mean 100% stable results are almost assured with slightly more voltage or better cooling. The point of this is not to find your ultimate overclock, but to find out the following: can I run the chip @ 3.6 fully loaded for at least a little while without it heating up to insane temps.

If you find that you can run it @ 3.6 100% stable, then you'll likely want watercooling to get you much more comfortable temps. If you can't get 3.6 stable than just keep your current cooling because the difference in temps just isn't worth it and it's unlikely the lower temps will buy you that stability. This all, of course, is very dependent on how much voltage is necessary for said stability - anything over 1.55v and you're going to need good watercooling to keep those orthos temps in the 50s(c). You made it clear (and it makes sense) that you don't want/need to wc your video cards so I would not suggest investing in watercooling unless you have that 3.6 stability.
That sounds like very sage and cogent counsel.

The fact is that at 3.6Ghz the heat goes through the roof under pressure from orthos and quits after a couple of minutes. It isn't undervolting it that kills it; it is the temperature of the quad. Volts don't seem to really matter and I can keep them at the low-ish levels outlined above so subject to your opinion, I would say the volts aren't part of the equation relative to heat or stability at least at the 3.6 level. So following your reasoning, it would not be worth watercooling.

However, considering the following, would you change your mind?

It runs all day long at 3.6ghz in Windows with reasonable temps e.g. (idle ~34stressed by my apps ~52) with all the trading and business apps that I put on it. I'm not a gamer so it will never be pushed to orthos levels anyways.

With that preamble, forgetting about any cost/benefit analysis, and considering I would like it to clock at around 3.6-3.7 with something more comfortable than 52C under MY (not orthos) load, do you think water will bring the temps down to something more manageable?

As an aside I see the new Dell H2C 720 is running at 3.7+ under quasi water...and that's a Dell for gosh sakes...running essentially the system I've built. Gotta be able to beat a Dell.
