Plenty of air enters through the decrease vent, which feeds the bottom-mounted 180 mm consumption fan
This 12.8 C rise from open take a look at bench to enclosure with the identical CPU cooler prompted me to once more query putting the AiO cooler’s three 120 mm followers up towards the vents, since I used to be in all probability decreasing airflow. The hissing sound throughout masses from the vent holes informed me that air was coming into, however there was fairly a little bit of resistance. So, don’t try this. There is clearance to mount such a cooler and followers both method. Honestly, an enormous air cooler, with assist from the 180 mm Air Penetrator fan down under and vents above, could be my selection for the CPU on this case.
As to noise ranges, these will differ by part choice, clearly, and with my haphazard little construct I measured, as constructed with 360 AiO, “normal” motherboard fan profiles, and a full pace AiO pump, some 32.4 dBA at idle and 39.3 dBA underneath load. Again I used to be reminded of my mistake in mounting the followers on the skin of the radiator, because the followers drawing in air instantly by way of the vents at such shut vary produced fairly a pronounced hissing sound.
I’ll add that my issues about noise ranges from the Air Penetrator fan had been unfounded. I suppose I keep in mind operating the three on the backside of my Fortress FT02 at 100%, since I used to be over-volting and overclocking my two air-cooled Radeon 5870 GPUs again then. It was properly behaved right here.
