Re: how much water?
Ok, thank you jrautmo and bigben for the feedback! I am only testing right now, so I'm not terribly concerned, but clearly I need to add more water. It's going to be tricky when I do that, as the reservoir is quite small. I'm probably going to have to fill the radiator and/or the lines first, otherwise it will take me hours to fill. The problem is that the fan/radiator component were a pain to mount to my case. It won't be fun doing that when the system is full of water!
Ok, here are details on my setup (case is an Antec 660AMGPLUS).
For starters, the pump, radiator, and block all have 1/2" barbs. As you might expect then, I am using 1/2" tubing. The res mates directly to the pump, and the inlet has a 3/8" fitting. I think I will have to buy an adapter join and some 3/8" tubing for that, but I haven't experienced any leaks during testing (well, I'll see when I get home tonight!). Oh, I am using clamps on all of the barbs on all components.
Secondly, because of the way the res mates to the pump (you can check out both innovatek and overclockers.com to see pics), I've had to mount them in the bottom of the case. In contrast, the fan/radiator are mounted to the top of the case. I realize that's the reverse of an ideal situation, but the pump isn't having a problem circulating water. I'm using 3 1/2 feet of tubing at most, as my case is only 17" tall. So, the water is flowing from the pump at the bottom to the block, from the block to the radiator at the top, and from the radiator back down to the reservoir.
I'm not using water wetter for testing. There are definitely small water bubbles in the lines though I bled the system, but I'm fairly confident that's because I didn't add enough water. The line from the pump to the block is completely filled, as is the line from the block to the radiator, but the line running from the radiator to the res is not- I think it's filled about half way. Like I said, I had a rough time filling. The res is only like 1 1/2" wide and deep by 3" tall. It's a rather unique set up the way it mates to the pump. You remove the gray housing from the eheim and then insert the exposed shaft through the outlet hole that is cut into the reservoir. They mate very nicely, so the shaft is technically submersed in the res, but the whole pump does not sit in the res obviously.
Sorry I don't have any pics. I went to take some last night, but I've recently upgraded my OS to XP, and my software for my webcam is incompatible. I hope I've given you enough details here. I think you've answered my question in any event. I'll be happy to send you pics when I have this up and running and when I get some compatible software for my cam.
Kind Regards,
