Mac Pro 5,1 Liquid cooling?

Did any one tried to install liquid cooling?
I've just ordered two xeon x5690 to my old middle 2010 Mac Pro and since cooler will be removed any way is there any chance fit some of new liquid cooling system in 5,1?

The existing air coolers have all sorts of sensors in and around them... it is likely to protest like heck.

There are vids of a liquid cooled 2008 MP I think.

Unless you are looking for silence, you won't need liquid. The MP air cooling is very good. If temps are a little hot, install some fan control software, raise the min fan speeds a tad and be done with it.

Mac Pros Air cooling is enough for every dual 6-core Westemere Xeon, even for dual 3.46 6-Core.

I think that only way to have water cooling on CPUs is to remove every Fan in the chassis, and that is not very smart. This is only way because if any sensor on main or logic board can not detect RPM from any fan and adjust its analog control, other fans automatically go full blast, but if you remove every fan, there is no blast

Why this is not smart: you need fan for PSU, HDD bays / PCIe part of chassis to maintain safe air temps for other components.

Would be a serious project. I wouldn't bother unless you really know what your doing.

I've never trusted liquid cooling.

Nope. Wont work. And it's silly. Your best bet would be to get a clear tube, pump super-cold air from the bottom-up. Then cycle it through again while constantly super-cooling.

MUCH MUCH better than liquid cooling, and it will allow you to overclock the CPU and GPUs and run them at very high temps.

Make sure their super-cooled air has little-to-no moisture.

Couldn't you theoretically add liquid cooling to the existing heatsinks? It wouldn't be as good as liquid cooling directly, but the colder the heatsinks are the colder the processors are, which would let the fans run slower or the processors to run hotter.

It'd be a lot of work for limited gain though; a more useful solution might be to just get air-conditioning, either for the room (potentially cool several machines) or just get a portable unit and have it push cold air at the computer. Obviously it cools the whole room, and the computer is going to make the air conditioning unit work harder than it needs to, but the colder the air is coming in, the more effectively it cools. Plus if you get a new machine you don't have to transfer over the liquid cooling or buy a new liquid cooling unit, and if you get especially hot weather then you're not going to mind having some spare air-conditioning

If I had a spare room where I could do something like that then it's what I'd do; namely move my computers into a discrete air-conditioned room out of the way, and either setup another machine as a dumb-terminal or see if I can video cables etc. that will work over long enough distances to route them into my various, normal temperature rooms. If you have a basement you could even partition off a part of it, provided it's dry enough.
