Anyone ever tried using a modded office water dispenser for cooling their rig? I have one sitting in the hall press that really makes the water very cold. I am sure it could be put to good use for liquid cooling a PC. Any thoughts?
Off the top of my head, they're phase-change systems, like fridges, aren't they? A quick Google revealed a similar thread elsewhere and I think they have a point; these things are supposed to work incrementally and in cycles, not all the time. Having said that, if you were going to run a normal W/C set up anyway, and use the phase-change gear to just cool the water a bit, that could work... I mean, it's unlikely to be a huge improvement - if you run a sort of chilled-water-cooled system, you're still not going to drop below room temperature, because heat will enter through your rad, which is a pretty poor result for phase-change. But it could be down some on traditional W/Cing.
Umm... that would be awesome. I don't even think you would need a rad on this, especially if it's a 5 gallon (or whatever your silly Metric units would be) jug type.
It does have the big water bottle on top of it. I think how they work though is so much water goes in to a smaller reservoir inside and gets cooled down there, that is the bit I would be interested in. If it was the full bottle you had to fill with coolant it would cost you a fortune LOL
The problem here is the rate of cooling, if the cooler doesn't remove the same amount of energy from the water that the CPU/GPU etc put in then the temperature will rise. In a water cooler the only energy that has to be removed is what seeps into the small reservoir through the insulation and what comes in with the room temperature water from the big bottle. In a PC the CPU and whatever else is being cooled are pumping hundreds of watts into the water. Moriquendi
I always thought the water/liquid in a loop never got warm anyway as it passes over the components so fast.
That's not quite right. The water doesn't immediately head up, sure, it just (slowly, because of water's high heat capacity) reaches a temperature plateau and essentially stays there throughout the loop. You're inputting heat at a certain rate, and the rad is losing it at a certain rate. Although 'speed' (flow) means it never heats up locally (say, around the CPU), all the water warms eventually.
you have a radiator and fans to keep it cool. that's why I said what i did. pour hot water in and see what kind of temperature it is when i comes out. it will show if it is possible to use for watercooling without any fans or radiator.
