I transmit the link of these results on the Winter One thread. Thank you, it's perfect.

I'm not going to be able to use the 280 Xflow, but by using 240, it could be a good way ... My waterblock is very restrictive (165 microchannels of 0.1mm)
I don't think you should sacrifice radiator volume by going 240mm, that would affect heat dissipation way more than flow restriction would potentially affect CPU/GPU thermals. If you can't find a review of that block where flow rate dependence was tested perhaps you could do a temporary open bench build and test that block yourself at different pump speeds/flow rates? I wouldn't expect a ~20% drop in flow rate to make CPU thermals worse by more than ~1.5℃ with a standalone CPU block.

Performance of EK blocks @ 1.1 GPM, 1.65 GPM and 2.2 GPM:





From this review.

1℃ difference between 1.1 and 1.65 GPM. They didn't test below 1.1 GPM unfortunately, that's where the difference should be a bit more noticeable.
I will test EK Velocity at 1.0 GPM and below around March when I tear down my current T1 build.

New fans​

Last weekend I tested EK-Vardar 140ER D-RGB fans that I intended to use in ML.



The good:
  1. Airflow is great
  2. D-RGB cables are daisy-chainable
The bad:
  1. They are 26.5-27mm thick even though the specs state they are supposed to be standard 25mm. That's quite a big manufacturing tolerance. With anti-vibration pads which these fans absolutely need the thickness would be 28.5mm-29mm. Those extra 1.5-2mm could cause a problem with fitting the side radiator.
  2. They are unacceptably noisy at the minimum speed. Compared to NF-A12x15, Vardars are a few dB louder at the minimum speed and ~6 dB louder at the maximum speed. Having so much radiator volume to work with, I want my PC to be silent at idle.
  3. 1 out of 3 fans I tested produced some rattling sound at any speed.
I decided to return all 4 of them and instead get 2x Corsair QL140 for the front rad and 2x Arctic P14 for the side rad.

Here's how QL140 look like when hooked up to Splitty4 and controlled directly by the mobo (without iCUE and Lighting Node):



Yes, rainbow mode is a bit messy but I prefer color cycle anyway. QL140 are very quiet, comparable to NF-A12x15 which I have in my T1!
I will keep them at a considerably higher speed than Vardars and hopefully, the performance will match. I don't intend to use Lighting Node, I'll just make a custom adapter cable for easier cable management.

The other two fans, Arctic P14 should arrive in the next few days and then I'll compare their noise levels with QL140.
