Hello I am fairly newb to this, but wow, nice work Martinm210, and hey I don't live too far from you; I live in Welches, OR; at the base of Mt. Hood. Anyhow, yikes, I just read this whole review and my head is spinning. I am inclined to the GT, however I would like to know what you and others think of the AP-14 as it was not tested? I can only assume it would be that much quieter. Nice videos btw - those really helped. The GT had a more comfortable noise than the other fans I was interested in. I would guess the AP-14 is similar in sound but just a bit slower? However would it still perform decent enough for use in a rad set up? I plan on running two Feser X-Changer Triple 360 mm Extreme Performance Radiator - 15mm Spacing. Another concern of mine is that the GTs have a huge disc, and I worry about that creating a dead spot in the middle, as well as what it might do for static pressure. Sure the flow can be tested and graphed, but does air flow alone indicate actual performance for cooling a rad? I know you used a rad in your setup, I guess I am just concerned about it cooling equally without any dead spots. Any thoughts?
