Loop Flow Rate and Temps

I got my MPS Flow 400 set up and running. For some reason, I am capped out at 38L/H on my loop. Once I get past 3.5 on both pumps, it just pegs it. When both pumps are on 2, I get about 19L/H.

I am using 7/16 ID tubing, with 7/16 compression fittings. I have no kinks in my tubing, and I pinch the tubing, I do get a flow drop.

I wonder if I got a bad sensor or does this flow sound about normal. :confused:

My coolant temp is 25.3C at idle, and when I load up with P95 my coolant temp goes up to about 26.1C. MY temps on my 3770K at 4.5GHZ is 76 with 1.248 volts and both pumps set on 5.

For some reason, one pump makes an odd humming noise on anything but the highest settings.

Does this sound like a fairly normal running loop? My ambient room temp is 20C.

Edit:

Just found out I had to import flow data, I am pegged at 399L/H now. That's more like it.

Set both pumps on 2 and I'm getting 358L/H. Other good news is I tipped my case again and must have had a large air bubble. Pump is now silent, and I got a 3C drop in my idle and load on my cores.

I wish I could provide better info, but I can only tell you what mine is in comparison. I have 2 D5 pumps, both running at max speed (5). My loop is fairly complicated, as I have 4 360 rads (2 Alphacool Monstas, 1 TFC Admiral, 1 XSPC EX360) with 2 sets of Koolance QDCs connecting the 2 Monstas in my CL pedestal to the main body of my M8 case. For tube, I run Primochill Advanced LRT in 3/8" x 5/8", with various compression fittings (XSPC / Bitspower). I average 2.9L/M or 174L/H. My flow meter is a Koolance INS-FM18D. I started out with 3.1L/M (186L/H), but it dropped to 2.9 for some reason, and stayed there.

So without knowing your pump setup, you're getting a lot more flow than me, assuming both of our flow measurements are accurate. Your numbers look pretty good, assuming both our measurements are correct. Looks like either I suck, or you're doing great, or we're both wrong. :D
 
I think we are both good. You are running a heck of a lot more rad than me. I don't know what the QDC's will do for flow, but I would think they would cut it down a fair amount.

Did you zero your flow meter, or can you do that with that model? I am still learning the Aquaero 6 and all the gadgets and bells and whistles.

Thanks for the reassurance. There is nothing better than letting Valley loop and watching your CPU that has fair overclock running only hitting 45 after looping an hour.
 
Nah, mine is digital. The only setting on it is a switch for tube size. Your CPU temp is nicer than mine! My 3820 needs 1.276V to stay stable at 4.3Ghz though, so it appears I didn't win the silicon lottery this time around. :)
 
ouch 1.276

I can actually run everything on 1.22 except BF4. That causes WHEA errors. It can PRIME and pass IBT, but not that game.

I'm still learning what all I can do with the Aquaero, but let me say, this thing is the cats meow. It's the first thing I have found that I can replace my G19 and never look back. As soon as my Rhino comes in I plan to pick up maybe a Corsair keyboard or something similar that I don't need to run drivers for.

I would also like to delid, because I have one core that is always 8-9C hotter than all the other cores at all times, even under multiple coolers and mounts. With these temps, I doubt I will, until a month before I upgrade in a couple of years. Then I will see how long it takes to fricassee it for some all out benchmarks.
