Thermaltake Core V1 vs Supressor F1 - what makes a case quiet?

[WildW]

I'm considering these two cases for an ITX build. They're both very similar except for minor differences.

I'm looking at transferring my existing PC into an ITX case from a mid tower (Zalman Z9) for portability, though the big case has the benefit of being big, open and quiet. Hardware as follows:

Asrock Z77e-ITX motherboard with i7-2600K @ 4.6, under a Corsair H75 (Single 120mm rad all-in-one water cooler) which keeps everything under 65C with bare minimum fan speed, even at full (non-AVX) load.
MSI GTX 1060 mini (short ITX card)
No spinning rust, SSDs only.

It's super quiet at the moment, partly because the big box sits under my desk. An ITX build might sit on the desk instead - not least because these cases have their PSU intake on the bottom.

I'd still like to keep everything as quiet as possible. In both cases the CPU cooler would sit behind the front panel. The Core V1 looks like it has less restricted air flow to the front intake, pulling straight in through the front mesh while the Supressor F1 has to draw air in through vents in the side of the front panel. . . but that hides the fans away more.

Which design do people think is likely to be quieter?

Other cases in the Supressor line include sound-dampening panels, but I see no mention of it in the F1 specs, which wouldn't surprise me given it's an ITX case. It doesn't look like there's much in the way of noise reduction versus the V1 other than a solid front panel instead of mesh.

I'd go for the V1 given direct airflow through front mesh. I don't think it would be louder by much, but it might make some difference in temperature. I'm not a fan - pardon the pun - of 90 degree bends for airflow with side vents on front panels. Quietness comes down more to the fans you use and what speeds they are running at more than anything, though, especially in an ITX form factor. If you don't have a quiet fan on the rad already you can always get a Noctua, be quiet!, Corsair ML, Arctic, Noiseblocker, or other quiet fan, many of which are inaudible at lower speed even in open air.
