We were able to install a 92x14mm Noctua fan in-place of the 2.5″ SSD using anti-vibration fan mounts. We set our 92mm fan to exhaust and AIO fans to intake. You can fit a 92x25mm fan if your using custom cables.
THERMAL BENCHMARKS
CONCLUSION
The DAN A4 H2O is an excellent 11L case. Cooling performance is as expected for case of this size & hardware compatibility. Our build faired little better due to using unofficial 92mm bottom exhaust fan instead of 2.5″ SSD. One thing we noticed was having our GPU fans running increased CPU temperature in CPU only workloads. The A4 H2O is among the best SFFPC cases currently available and has an excellent pricetag to match.
