Slower pump to avoid dry pump.

[T.Vengeance]

Hopefully this isn't a repeat question. I've searched using google (https://www.google.ca/search?q=slow+pump+site%3Alinustechtips.com&oq=slow+pump+site%3Alinustechtips.com&aqs=chrome..69i57.9370j0&sourceid=chrome&ie=UTF-8#q=slow+pump+water+cooling+site:linustechtips.com&start=10) and nothing came up. Anyways, I'm thinking of building an unconventional small factor PC sometime down the road and cooled using a custom loop.

 

I was wondering if I could avoid using a reservoir by slowing down the pump to avoid having it run dry.

Nope, unfortunately that will not work. You would have to somehow have an absolutely airless loop that is perfectly air tight which is simply not feasible. You definitely want the res. Even if it's a small one.

just use an all in one cooler or a pump/rad combo (i believe aquacomputers has one)

You can use a t-line instead of a res.

Yeah I was thinking about that too. My solution to that, is just take all the waterblocks in my loop, connect them together while leaving one end open. Then I'd submerge it in water and run the pump for 5 min or however long it takes. Would that work? After that, I'd connect it to the pump, take it out and leave it to dry for a day.

Unfortunately for this "unconventional" build, it won't work.

With normal tubing and fittings, you're still going to run into evaporation issues (assuming the submerging would work). I think your best bet is still a very small reservoir. What makes you want to ditch the res?

Over the next few months or so, I wanna create an all-in-one computer like an iMac but much more powerful with a GTX780 and an FX-8350. I'm planning to cool it with a custom rad I'm designing which hopefully will work (will do some testing to see how much watts of heat it can dissipate from just convection cooling). So that'd being said, using a res is a bit on the unsafe side since I'm assuming there's an air opening at the top so water can flow out of the res (Please correct me if I'm wrong. I've never watercooled before). I don't want that water to leak out if I tip the monitor.

Liquid cooling loops are closed. You should be able to turn them upside down without any leakage. This doesn't, however, prevent evaporation from occurring while using rubber tubing and o-rings.

that's disappointing....Thanks for telling me about that evapouration problem. I didn't know about it. Is there any way to counter it?

Using a reservoir and filling it every now and then. It's the main reason why any loop has a reservoir (as well as greatly helping with filling and bleeding the loop). A t-line is an option, but it's not exactly ideal if you ask me. Again, I suggest a tiny reservoir, but this time I give an example: The Swiftech Micro R2.
