It was my first time ordering from them: https://www.quietpc.com/nf-a12x15-pwm-ch-bk-s
Thanks, have checked them out and their prices are very competitive; will keep them in mind for future purchases.
I ended up settling on the the Scythe Kaze Flex 12x17cm RGB, since I wished to through a bit of pizzazz into my build. Also sff forums had a review ranking them above the Noctuas in both dBs and temps.
Only difficulty will be closing the top of the T1, as the extra 2 cm brings me right up to max clearance.
