I’m looking into getting one of these.
But they have also downgraded the fan which is dissappointing, the previous version of the RM1000x had a magnetic levitation fan (NR140ML). Given that both versions are currently available (with the older coming in cheaper) – I am wondering if the prior version is a better purchase
I would buy the new one. The ML fan was a bit noisy with the specific fan speed profile.
I bought one of these. It made a small amount of coil whine when I tested it in my old PC, but only when idling in windows (starting any app up made the noise go away completely). However on my main PC it makes no noise whatsoever, phew! I like the fan control, I have it turned to it’s lowest setting where it is still inaudible but at least this removes the heat rather than letting it radiate in to my PC case.
