Is there any advantage of having this on a high power/flow setting over a low power/flow?

So If I had this on setting 1, the lowest pressure, then surely the flow would pass slowly through the radiator allowing it too cool more efficiently?

thoughts?
 
The difference between the vario at 1 and at 5 in most loops is usually only a degree or two.Just set it to the highest speed thats its inaudible to you(Usually 2 or 3 or most people)
 
Not a lot in it as said above. I have mine set to around 2 because at that I cant hear it and temps are as good as at 5 where I can hear it. I have only ran mine on 5 to clear out the bubbles after a new install/refill.

Argument....if it is going through the rad slower it should cool better, surely then it is sitting over the heat longer so it should heat up more too? Basically flow doesn't make a huge difference as long as there is enough of it, there is probably an optimum setting but I cant see the point in fiddling for a degree or 2 (I'm going to be flogged for this aren't I)
 
^ no your answer was pretty spot on.

The main thing is as long as the water is moving somewhat. Having more flow doesn't always equate to much better temps.

Just set it to a speed your happy with noise wise. Mines on setting 3. Pretty loud at setting 5 for 1ish degree at most.

However I do notice more of a difference at setting 1 temps wise.
 
Interesting..


The reason I'm asking it's that compared to the same pump i have in another system, it's definitely audible.

The only difference is that this is part of the XSPC D5 Photnon 170 which is attached to the case whereas the other is a standalone on a sponge damper.. So i'm wondering if i'm getting a slight vibration on the cae. Not sure what i can do.

That's a very valid point.
 
You're probably right about it being a vibration thing.

As for the speed setting, I'm with MrMD on that one.
While it is a valid question, and those settings are there for a reason, I think that watercooling tends to be one of those subjects that tends to suffer from overthinking things :)
 
Jayztwocents did a video on it a while back, he found having very slow speed gave him higher temps but thats cause he had 3 way SLI with overclocked titans.

I had a loop that went 290x>290x>CPU in the past and i found although slowing the pump speed down to 1 made no difference to the GPUs temps it did heat up the CPU a little, the higher pump speeds kept the loop temp equal and stopped that happening.

The vibrations are where all the noise comes from, i recently moved my d5s from been suspended between 2 pipes to been mounted in Bay reservoirs. They went from been silent at speed 5 to annoying anything over 1.

I think i'll soon be doing away with these bay reservoirs, tis a shame cause they look nice :)
 
The slower the pump is running, the larger delta there is between the hottest part of the loop and the coolest part. I have a CPU and GPU block then 2 rads. At max speed the delta is about 1-2C but at setting 1 the delta is about 7C or more.

I use setting 1 for the noise.

I thought mine was on 1 since the install but a quick look a month ago revealed it had been running 5 the entire time. silently! (well I certainly didn't hear it!)

oh well I will leave it on 5 I guess.
