I used manual RPM adjustment slider in ASUS AI Suite. Unlike fans, I don't find curve very useful with pump, so I just set it to fixed RPM. In hindsight, I'd probably had been fine with vario pump.

Ok I see, well honestly my loop atm is not exactly restrictive, block is Supremacy Evo (2011-3 jet + insert) and radiator 420 sized UT60 just like Gil80's + pump and reservoir, I don´t run AIsuite atm trying to have a super clean Win install but I do use bios to control, are there any differences between what AISuite can do over direct bios access?

I probably would not need 800 rpm's from a D5 cause they are very quiet anyways but just that I´m very picky with the settings, I want that max performance when computer working at full load on high overclock for longer periods, but at same time I want it as close to dead silent as I can possibly get it cause like I said I sleep just next to it, sensitive I suppose? redface.gif


Maybe Jakusonfire's way is something I should look at a proper controller, I know nothing about these controllers though + economy is always limited?

Every set up is different and one might see different results. This is what I've found in my loop.

My loop has a 360 rad, a 480 rad and 3 water blocks. I have a D5 vario set to max, but controlled manually (voltage, not PWM) by a Koolance controller. In my loop, pump speed has no affect above 3200 rpm. When 4000 rpm (and above) is reached, the temps actually increase (nothing dramatic). I assume the pump is adding heat when it runs faster. (?)

Using the Koolance, I can not test below 3200 rpm because that's what the pump runs at with the lowest setting on the Koolance (setting is 1-10). I've thought about changing the setting on the pump, but it's not easy to get to. I am curious now and might test with the Koolance on max and the pump on 1. I believe, I'd have to look, the pump runs at 2400 rpm at 1.

My rads are push/pull, so I have 14 rad fans (all pwm). I've tuned them so they don't turn faster than 60/70% (1600 rpm) during a stress test (5906x, 2 980 TI Hydro Coppers) and the CPU maxes out at 60c. If I run the rad fans on full tilt, I can lower the CPU to 54/55c (noisy though). During 'normal' operation, my fans run at 600 rpm and when I game heavy, they might turn 1200 rpm (still very quiet). My goal was power, cool and quiet (in that order). I never thought it would be this quiet, so I'm very happy. biggrin.gif The Koolance controls 5 'case fans' (voltage controlled) and they won't run slower than 1100 rpm. If I had gone with an Aquaero 6 and 5 PWM case fans, my rig would be nearly silent. I'll probably make this change at some point.

Conclusion in my set up: PWM fans are important, but pump speed has little (if any) affect once a certain speed is reached. And finally, I never hear the pump.

I use 12 fans not PWM but all connected to a PWM hub. They are all 140mm running on 600~700rpm on idle and Max at 1200rpm on load. Using 3 water blocks and 3 rads the noise is ok though not silent.
600rpm it is silent but the phanteks fans are slowly failing.

The difference between AISuite III and the BIOS...

I have a R5E, but I assume it's the same for all ASUS MBs.

1) AISuite III allows you to enter the sensor to follow (like water temp) while the BIOS is CPU temp only.
2) AISuite III allows you to configure 'ramp up/ramp down' times. This keeps your fans from immediately changing speeds when the temp does.

I would rather not use AISuite III, but these differences can be important if used. I found using the water temp to control fans provides the coolest/quietest rig. By maximizing the 'ramp down' time (204 seconds I believe), the fans (they are rad fans) will continue to spin faster while the water is cooling after a stress test. I tested with 'ramp down' set to 0 and the water temp would return to 'normal' in about 6/7 minutes. When I set the 'ramp down' to max (204 seconds), the water temp returned to normal in 2/3 minutes.

If you don't use either of these features, the BIOS is the way to go. I wish ASUS would add these parameters to the BIOS.

I use AI Suite II and it's has more control over the BIOS. In addition I found the BIOS to be problematic when it comes to controlling the fans.
With a 16GB RAM and SSD as main drive, I don't care about the resources Ai Suite takes.

Cool, really appreciate the info guys. I rather not installing more programs either but I will reinstall AIsuite and play around with it again, soon going to reinstall Win again anyways cause it started to give me problems once again so will most def look into the extra options available + play with spin up/down delay etc.

Aquaero seam like a nice little toy, time will tell which way to go though have some reading to do..

Regarding differnt D5's I found this, Alphacool is not in there did not find it.
