You don't want to recycle air through rads..thats a goo way to loose most of their efficiency.

Yes rads are pushing the air out.

What is bothering me is why adding 120 Rad and 6950 increased the temps from 54 to 76, and why then changing to serial increased further to 86. These were the only changes to the loop.

You added more heat than heat dissipation. Changing from parallel to serial and getting an increase in temperature sounds like you're having restriction issues. The DCP 4.0 is a really weak pump. Contact bmaverick and get an MCP350 or go and find a D5. Also, try bleeding out all of the air in your loop. Rotate the case around while the pump is running to try and get out any air pockets inside of the rads.

I'll think you'll find that the EK 4.0 with 800lph and 3.6M head pressure is not weak at all http://skinneelabs.com/jingway-pumps/ buzzy yes, weak no.

I disasembled the loop, I can not attach spacers because the fitting screw is too small - after I attach the spacer, I can not screw in the fitting.

I'm still thinking it has mounting issues.. you have enough rad for decent temps and that pump is good enough for that loop may hover around or below 1gpm but it wouldn't result in a 20C increase.. You never mentioned cpu temps so i'm guessing those are normal. Since you already have the loop disassembled why don't you check the gpu mounts real quick.

By mounts you mean how the block is attached to the pcb? I did not take off the 6990 block so I guess it is all fine with 6990, with 6950 I was as precise as I could, using noctua thermal paste exactly like it was shown.

Then your problem can be the fittings going too deep.

If you use teflon tape to seal the fittings instead of an o-ring you can use thinner spacers, until you reach the point where you can screw the fittings but they don't go way too deep.

How long are the threads?

Anyway, how's your water temperature?

And yes, the DCP 4.0 isn't much weaker than a Laing D5.

You're going to have to do some basic measurements to isolate the components:

1) Radiator/fan combo - Measure the water temperature and the air going into the radiator, what is the difference? <10C OK, >10C your radiator/fan combo isn't keeping up with the heat.

2) Pump - Get a couple of 5 gallon buckets, and pump water from one to the other. Use a stopwatch to measure the number of gallons in 1 minute. >1GPM OK, <1GPM need more pump.

3) Contact/Mount - Take a picture of the paste spread after removing the block. Thin/transparent spread over the core = OK, Thick layer that you can't see though, not good....need to figure out why.


I suspect you have one or more of the above, but without doing some sort of isolated measurement/tests, there is no way to break it down and figure out what is going on. None of these things take specialized equipment. A simple $10 aquarium thermometer can be used to do the temps, and a couple of washed buckets and phone timer to do the flow rates, etc. It just takes time, but you've got to do that yourself.

Break it down piece by piece...could be more than one item, but 20C is unlikely to be pump related unless you have something really messed up there. More likely a bad block mount

This is really sound advice.
