How long has this loop been running?

No, the air is warm, but not what I would consider 'hot'. I definitely do not think there is any air in the rad. This loop is about 2.5 years old or so now, I took it apart a few months ago (trying to figure out what the heat issue was) and cleaned everything (was a little cloudy) and replaced the tubing / coolant. From the radiator, I have it feeding into a vertical Fillport that "T's" into the reservoir. (I only reason I even used the Aqua Bay was because I wanted a flow indicator on the front, and that was one of the only ones available at the time.)

Any air that is in the system floats to the top when it gets to the DD fillport.. Bleeding the air out is actually really easy with this set up.

Also what makes you say you got bad advice about your loop? Seems fine to me.

This is for my new Cosmos 2 Build.. and when I put it together, the "suspect" advice I got at the time was to go straight from the pump to the CPU.. now the general concensus is to go to a rad first as the pump adds heat to the loop. Going to the rad first gives you the "coldest" water to the CPU / GPU. But since I am not trying bench clock it, I just said 'meh' and left it like it was. I looked at your build man, super impressed.. you have some awesome photography skillz! How do you like that Lamptron FC? I got my replacement on-board from CM yesterday and it does the exact same thing as the original one.. so I either need to find some fans that will play nice with it.. or I forsee a Lamptron FC in my future.

If that's true, have you tried taking the plastic cover off the top to improve airflow over the radiator?

Yes, it's mounted to the top.. I ran it without the plastic cover and it doesn't really make a difference TBH .. and really neither does the fan speed.. whethere they are low, or cranked to the max I don't see any real difference in CPU temp, maybe 1-2 degrees, but nothing to write home about.

The pump is definitely on my short list of suspects, and the block is #2 confusedsmiley.png

Thanks dude, the lamptron FC5 v2 is great although I'm not using it to anywhere near its capacity at the moment. I've read a few hints here and there that it's possible to run my D5 off it, although I haven't had the time to look into that properly.

About your loop, everyone loves to say "loop order doesn't matter" but it's more accurate to say "loop order only makes a very small difference". In your case the change you're talking about would probably only be worth a few tenths of a degree, so don't be too hard on your buddy tongue.gif

Still a bit mysterious why your temps are so high... if you're sure it's not an air bubble then yeah it could be poor flow (although in that case I would think the water would get noticeably warm) or a poorly seated block.

If I hadn't just dropped a ton on watercooling parts for my original Cosmos I'd be lusting after the Cosmos 2 myself. If you ever want to get rid of your old case, I might be interested in the windowed door biggrin.gif
