You're not overclocking the bus or dram, so there's no reason to go all crazy with the VCCSA, VCCSA LLC, etc. If you bump the bus to 133 or something, then it might be useful. I don't think I would personally enable LLC on VCCSA past medium even if I had all 8 slots filled and overclocked: wouldn't want to risk burning out the IMC.

AIDA64 checks for stability with the full instruction set; but you should run the high temp cpu (less ram) Prime95 as well because it creates a larger CPU load (more vDroop). With the CPU current set at 120%, I'm actually surprised that your system doesn't shut off running at 1.4v.

good going....ur fan speed are at 40% rite...cant u increase them to 50%...in ur previous photos that changed decreased ur cpu temps by another 2c and delta t by 0.4c....both with 100% pumps....but after that at 60% fan speed the temps increased...and i think a 10% increase wont affect the noise level that much...maybe that is the best spot for everyday computing if the pumps going 100% fulltime is ok..

Thanks for the analysis, I'll try both 40 and 50 and let you know how it went.

(I would try below 1.15v for both VCCSA and VTT)
I also think you don't have enough Vcore for that frequency. But maybe you have good chip.
I would put CPU LLC to high with current capability to 170%
VCCSA LLC to regular and 140% Current Capability
(Also, don't forget to put the DRAM Current capability to at least 130% (140% to be sure)
Check Raja Guide for better overclocking. Its the best guide for our board, many usefull info in there.

Thanks, I'll check the guide and look into your suggestions.

Couple questions when you get time, and if you want to answer them.
Are you using bulkhead fittings for your tubing to the pedestal?
Could you (or anyone who wants to respond) do a ballpark estimate of what an Aquero setup would cost me for 3 rad/2 pump/flowmeter/temp monitoring for my SM8? Just very ballparked, not sure I'm going that route but would love to if I can fit it in the budget.
But anyway a great build, and a pleasure to read.
EDIT: I picked up some more info on the Aquero. Nice system!

Welcome! I am using bulkhead fittings between case and ped. And yes Aquaero 5 is a real asset when tuning your system.

Thanks, I'll look into those changes.

Saturday night update:

I replaced most of the 90s with 45s or nothing, I also redid the rad pump so it's closer to the res. Unfortunately it didn't seem to make any difference in flow; I could only measure the flow the blocks and it is still .9 gpm. I also implemented Electrocutor's suggestion to put a valve on one of the fill lines and that resulted in a bump to 1.1 gpm. Thanks for that suggestion!

I also tested removing pumps and each pump adds only 0.2 gpm to the flow except for the first one which provides 0.5 gpm.

I have leak tested the new fittings AND replaced the Mayhems ... I also managed to liven up our living room carpet with some pink color. My wife was not pleased.

Moving on... I have started final wiring. Motherboard is done, I need to sleeve the GPU wires, add the custom power wiring for the Aquaero and some other misc gear, and I need to finish the lighting. I hope to finish it all Sunday.

I'm surprised that nothing but the valve helped: especially that having that other pump directly below the res didn't help. I wonder if you have one specific block that is considerably more restrictive than the rest that is holding it back?

If you had more than one Aquaero, I'd recommend setting them up in parallel (though I think you said you changed to just using one). You could run your chipset and vrm blocks in parallel as well if you think one or both of them are restrictive. Your flow rate really should be between 1.5 and 2 even with only two pumps at 60%.I'm glad the valve helped a bit, but it may also increase your air/water delta a tad.


Would you mind running a quick test for me? Open your valve all the way, so the blocks and rads are independent. Then unplug one of each pump in the double tops so each loop is only being run by one pump at 100%; write down both flow rates. Then, enable both pumps on both tops and write down the flow rates again. Lastly, close the valve and do the same 2 and 4 pump tests, writing down each flow rate.

I was surprised as well; clearly one of my blocks is horribly restrictive. I only have one Aquaero5 (cpachris has the dual setup; hopefully he reads this about putting them in parallel).

Here are the measurements. Again, flow is from the meter after the block pumps I don't have a long enough 2nd cable yet.

In the data, I use the term pump 1 to denote the pump in the 35x2 with the res intake; pump 2 is the out pump.

Valve open
  • Block pump 1 on, rest off - .6 gpm
  • Block and rad pump 1 on, rest off - .6 gpm
  • Block pump 1 and 2 on, rest off - .9 gpm
  • All blocks on - .9 gpm

Valve closed
  • Block pump 1 on, rest off - .45 gpm
  • Block and rad pump 1 on, rest off - .7 gpm
  • Block pump 1 and 2 on, rest off - .7 gpm
  • All blocks on - 1.1 gpm

I would suspect the chipset and vrm blocks before the Aquaero one. Martin has data on the Aquaero block and it's really not too bad. Something has to give though: four 35X pumps in series at 100% is about 24 PSI at 1.1gpm, which should be enough to start making hoses pop off and o-rings leak.

Are you running the pumps straight to the PSU and not plugging them into the Aquaero for testing? If not, try listening for a difference between when they are at 100% set in Aquasuite and when their PWM cable is unplugged (true 100%). Maybe we're dealing with an issue where 100% PWM is actually 30% speed or something.

Those results were without pwm cables attached. I agree it doesn't make much sense unless the flow meters themselves are providing wrong data. Honestly at this point I likely will just chalk it up to space aliens and be happy with the performance.

Do make sure you've put in the right cal value for the AQ flow meteres. The default is not correct; I think the value is 169 or something.

Yes....reading and following along with great interest.

dont give up....as it is pointed out one your blocks or rads is horribly restrictive...i would advise testing each rad and block for flow restriction independently but i dont want to overburden you wink.gif....perhaps one of the blocks still has some grit inside to block flow?....
