I realize sub-ambient chilled coolant would cause condensation if the computer resides in a 72f degree room. And this might be a dumb question but here goes. On the other side of my office wall is my attached garage that is not heated. It generally hangs about 43f, rising a bit when I bring the car in from a drive. So, I already have a pass-through hole and it's less than ten feet distance. What would happen if I kept my liquid-cooled tower out there for the winter? Good idea or bad? Would warm coolant cause any condensation in a cold case that warms up through use?

Neither good nor bad.
But mostly useless.

You're hoping that the cooler ambient in the garage will let the PC run at cooler temps? Giving better performance?

Any performance benefit will only happen if the system is actually thermal throttling.
Reducing the CPU or GPU temp from say 70C to 60C brings no performance benefit.

It's a good idea, but you must look at for condensation.

water gets warmer over time. So may be at first it keeps cpu at 70, but if you keep it under load for an hour it reaches 80 until it throttles. So it's a good idea to find a colder place like garage for it.

unlike air-cooling that temps are higher but stable. water temp doesn't stay consistent.
I think your idea is interesting.

Thanks folks. I just was remembering that the old server rooms were kept very cool. I have dual, loops three rads, vrm, gpus and cpu all liquid. Processor doesn't really get over about 70 even when over-clocking. Don't think I'm temp bound. 4790K runs stable at 48 for hours. Can game at 49. I've done about all I could to hit 5ghz but takes too much voltage to get there. Was just thinking the only other thing I could do is supply colder air to the fans, but I don't think temp is the issue anyway. Just out of upgrades, time to build another one I guess.

Can you just use very long tubes to keep your reservoir in the garage only? that may require your pump to work harder, but again pump+reservoir goes into garage and you won't hear it.
Just saying, you will upgrade the system and temps with that will be higher. So you may try long tubes now with a system that is cheaper for experiment.

Yeah Lei, I thought about something like that. My case has tube exits on the back and I thought about getting a couple sets of those quick-connect fittings. Then run tubes out to the garage with a large rad and fans out there and back in. Then in the summer just run a "jumper tube" in the back and by-pass the garage loop. I have an Evermax pump/res that is pretty strong but I don't think it could push 20 feet on it's own though. I'm an aquarist and I use several different flow-rate configurable power heads in the fish tanks. Was thinking I could use one of those somehow as a booster. Might be too much though. Even the smaller ones pump 300 liters per hour. They're less than $20 bucks.
I would mention that my CPU cooler is an 240 AIO and it does just fine. So I'm really talking about the open loop. It goes like this, pump out->240 rad->split equal to GPUs->thick 120 rad->VRM block->pump in. So it's just about the GPU/VRM Loop. That loop idles about 27c but gets up to 45+ or so when I'm pushing my Poseidens. They are older GTX 780s so they work pretty hard and seem to only take a slight overclock before they crash. And the loop takes a long time to cool back down, but I guess that's liquid. Hence the wish to get the coolant temp back down and more coolant in the loop so it takes longer to heat up. I was really expecting the two-radiator loop to be a little more efficient.

Ok Sarge I get it. You're an old Haswell guy too. What kind of voltage do you run on the 4790? Otherwise, got what I came for. Condensation bad. Temps are fine. I just wish the loop didn't heat up so fast and stay that way. More coolant wouldn't hurt, maybe external and keep the rad indoors. Think Exotic!

My 4790 is all stock. I've not seen any reason to up that, even though the capability is there. For my use case, anyway.
