thanks! Great to know someone in same shoes. I faced clipping sounds but it seems to have come from the two fan clips securing the 120mm fan to the bottom. After tweaking it the sounds are not there at low RPM but became apparent when above 1500. After that I tried removing the fan clips entirely and no problems at all now no sound at low or high RPM. The 92mm screw holes touch the anti vibration padding of the Noctua A12x15 Chromax fan which I do not see a problem. Now without fan clips, the sheer design of the Sentry keeps the 120mm securely in place so I don’t worry about it. I tried strings and cable ties but both interfere with max 48mm height of the cover so finally gave up.How do you find the noise levels on this setup? I have the same configuration except I have my fan blowing through the cooler (away from the mobo). The fan is quiet up to 1000 rpm (~55%) for me.
I saw a lot of people claiming intake was better, but that was mostly for the 92 mm fan, and when I tested with the bundled fan, it just became stupidly loud when set as an intake. With the 120 mm fan set as intake, I had issues with the raised screw holes for the 92 mm fan clipping with the fan blades. Did you file them down or add a spacer or something like that? The exhaust configuration avoids this issue by having the fan housing between the blades and the fins, which is ultimately why I chose to do it that way.
I ask because I keep questioning my decision, as everyone else seems to have done the opposite, but I have to disassemble my pc all the way to taking out the motherboard just to flip the fan orientation (perhaps I should have voted for the removable back panel after all ), so I want to know if it's actually worth it.
Edit: the fan is very quiet now at all speeds, even with intake setup. The intake direction brings fresh air to cool my m.2 ssd which is in dire need of it. When using Cryorig c7g in the past no such cooling and temps can be above 50deg active, now it is 40 deg or lower when active and 30+ on idle.
