Max OC Testing

For our Max OC testing, we have configured our CPU to run 4700MHz on all cores, set the voltage to 1.25V, and configured memory to XMP mode. This yields an approximate power at the wall of 600w under load (a 500w differential from idle, which pulls about 100w). This results in the CPU running at 4.7GHz on all cores during the looping rounds of Cinebench R20. The only test that completed without throttling was the Max Fans and 100% pump speed test. You can read more about this in our introduction article here.

Max Fans – 100% Pump Speed

ASUS Ryujin 240 performance at max overclock clocks, max fan RPM and 100% pump

To date, with each AIO working as hard as possible, no 240mm cooler has been able to tame the Max OC Testing and that does not change today. The ASUS ROG Ryujin 240 joins all but the Corsair H115i Platinum (which posted a temperature of 96 degrees Celsius) and the Enermax LIQTECH II 360 (which produced a temperature of 95 degrees Celsius) in the thermal throttling group.

Now that we have seen how all of our units cool, lets see if we can still hear!

  1. David, did you see the video by GN on AIO Setups and things to avoid?

    Air in the system will always travel to the highest portion of the system. Having the inlet/outlet of the radiator in the orientation that you have, will lead to weaker water-flow to the block.

  2. I’ve always wondered how AIOs deal with air. I had assumed they just vacuum filled them to eliminate all the air, and the hoses were flexible enough to handle the thermal expansion. Any air that gets in afterwards would have been either from a leak or suspended in the coolant and come out of solution, and would pretty much kill the AIO.

    Any air in a closed loop system is bad no matter where it collects – in a pump it will kill the pump, in a line it will kill flow, in a rad it will kill cooling, and anywhere in the flow path and it makes noise. That’s half the reason why you have a tank in a custom loop – so the air can collect there and stay out of your lines, pumps, and rads.

  3. Steve’s rational on air though made sense, in that if you place it on portion of the tank where the water migrates from hot to cool, it’s the least impactful.

    Yeah.. saw it. Couple of issues with changing the orientation though….

    1. Radiator tubes are not long enough on any aio tested so far to flip it over on the current rig.
    2. Would have to redo all testing for comparison data across all coolers.

    So, maybe when I’m in the market for a new case I’ll change it out, but at this point, less than perfect will be the way we have to do it

    Thank you for the explanation! Keep up the great work on the reviews!

    Just flipped through the video a second time. Overall, the main reason we would have issues in the current orientation is more related to bubbles getting sucked into the tubes – it seems to be the "best" of the "wrong" ways to mount it… So that’s something, right?
