I haven't done my Watercooling yet, but you should try adding another 360mm rad, is this all one waterloop, or is it dual loops? If adding a second rad doesn't help, you have the second pump, try to make a separate loop for the GPUs, so they won't interfere with CPU temps, like what temps do you get when playing games? Isn't real bench just a synthetic test that is supposed to stress the CPU to the max?
Are all the rads moving ambient air over them , Is your flow really strong, and are you using a tim like Coolermaster liquidmetal ultra? Adding more rads will probably not make much difference. At 1.33v 70c on a synthetic benchmark is VERY good. Not really sure why you're upset.

The outside rads (under house) have outside ambient on fans. Temps coming after cpu load ov 70c sit at 19-24 (no load on gpu) the 2 pumps in question are a pwm d5 at max speed and a d5 vario on setting 5. The tim used is the gelid extreme ( can this go bad after time?)
The pipework changes to get the stuff under the house. So internloop is 15mm. External pipework changes too 10mm air line with push/lock fittings with elbows and 4 valves inline.
So with temps going into the cpu of around 20c or ambient i shouldnt expect with even more rads too lower 70c i see on benches anymore? When it was resl frosty a few days ago my ambient was just over 1c and the temps coming ontothe gpus from the external was 8c. With an input of 60c from the cpu.
How does one make the temps all the same? A car radiator?

I've heard of tim drying out, but its not likely. You could try and use CLU and get a couple degrees cooler, but you're pumping alot of wattage out of that chip and the water can only wick it away so fast. I found that adding more rads to my setup added restriction and raised my temps a very small ammount. If you want ambient temps look into LN2 or dice, cause it wont happen on water.

Well damn. I didn't realize this was an externally radiated setup, that is out of my league.
Just curious, did you already post this setup somewhere else? Should I have seen it somehow? I don't see any info on your setup, but I'm just getting back into being active on OCN
Alrite so the crux of the concersation is achieving ambient isnt possible on water. Adding a monster external setup with 4x480mm may not lower my temps either. Is it limited by how fast i remove the heat from the cpu?
Ie flow?

If you look in my post history there are pics but not of the condensor and 240mm combined but of the unit on its own. Its ugly as hell and kind of embarrassing.
You cannot achieve sub-ambient temps without somehow exposing your heat wasters (rads) to sub-ambient temps. This may be with LN2, dry ice, or radiating externally to an environment with a lower temp. No matter what you have to prepare for condensation if you're going to try for sub-ambient cooling

Yeah. The cpu at a given voltage will be a certain constant temperature above the water cooling it. Like you said, if the water is 10c cooler, you bench 10c cooler. The thermal properties of the tim and metal transfer the heat at a given rate, as well as the water moving the heat away, and there is no way to tranfer and move 100% of that energy instantly. I hope that makes sense.

I dont want sub ambient. All j want is for the cpu to better reflect the ambient temps of outside. Thats why i askef if mounting a huge external setup bigger than what have nowoutside give me the temps im looking for?
I have not measured the water temps. Only the difference between leaving the cpu and arriving at the gpus (gpus not loaded)
I guess the advice i need then is what area shouldvi attack. I am prepared to build a monster external if thats the issue. I added a second pump thinkung it was a flow and head issue. Temps didnt change. A swingbof 10c ambient was about 7-10c change in max temps on cpu.
I tried too quote you its being funny. I have not measured temps of water only temp diffences on die between cpu and gpu. I have no idea if adding even more rads will lower my temps or not.
I'm pretty sure the basic answer to your original question is no, and that's not the point of basic water cooling anyways. basic water cooling is about lowering the temps of an overclocked component to the point of being effective. if your looking for ambient or sub-ambient temps then that's a whole other category.
1. dig a 10feet hole in the backyard
2. buy a BIG truck radiator and throw down in that hole
3. connect the tubes from radiator to a Iwaki MD70R pump
4. fill the system with water + 10% glycol (car antifreeze)
5.plug into youre custom waterloop ....and smile... you got temps below ambient in youre loop
