Air Sounds from Loop

I have an MCP 655 in the 2-Bay XPSC Reservoir (I forget the exact name). I figure the rest of the parts in my loop are irrelevant, but they are in my sig if needed.

Anyways, I set the loop up about 5 months ago, everything installed nicely. I bled the loop about as much as I could and I'm still getting excellent performance to this day.

However, every so often I will get air sounds from the pump, similar to the sounds I got when bleeding the loop. I assumed all of the air had to be gone by now, but I still get 'wooshes' every once in awhile, I assume, from tiny air pockets that are still present in the loop.

My question: Is this a normal and should I be concerned? Is my pump defective in some way or is there simply still some air present in the loop? I assume its near impossible to get 100% of the air removed from the loop. I imagine most of the air pockets would be in the top mounted 120x3 rad.

As I've said there is no other problems except for the noise. The pump is pretty silent itself (no louder than my GT 15s) and my tubing is optimally routed with no kinks. The liquid (Distilled water with a killcoil) is still crystal clear and I have never had any leaks or other problems with this loop other than the occasional noise.

Any input?
 
I have read that a bay-style res can be tricky to bleed. Have you tried tipping and/or gently shaking your rig to loosen up any potential air pockets still in the loop?
 
Yes, I did a lot of that during the initial bleed. I tipped and shook it pretty thoroughly. There was little if any air coming out by the time I was finished, which is why I was surprised there was still that much left coming out now. It did seem that the positions of the inlet/outlet on the reservoir weren't the best for removing the air, and that a separate reservoir would of been easier.

Maybe I will have to switch to one on my next cleaning.
 
Do you need to regularly add additional water to the loop? If not, I wouldn't worry about it.
 
If your not losing any water and had a pretty full system, does it look like any air bubbles in your res are making through the loop? I had that problem with my mcp655 setup, on the 5th setting it would occasionally eat some air bubbles and make sound. I turned it down a bit and the problem went away.
 
I have the XSPC D5 Bay Res. The best way to bleed the air out is to cut some tubing in half and stick it between the little curved tube and the inlet port for the pump. This will block the air bubbles from getting back into the lines. Just do that, then top off the res, seal the res, flip the computer on it's side a couple of times (DO NOT SHAKE!), and repeat until all air is out of the loop.

Works for me!
