This is my R9 380:https://pcpartpicker.com/product/RCL7YJ/xfx-video-card-r9380p2df5
If you want to reuse the shroud, you could use 92mm fans like the NF-A9x14 and retain the card's original dual slot size. https://pcpartpicker.com/product/PfXfrH/noctua-case-fan-nfa9x14
I did the same thing here with a 980 Ti:
Alternatively, you can use larger fans like in the LTT. NF-P12's are good: https://pcpartpicker.com/product/VNBTwP/noctua-nf-p12-redux-1700-pwm-708-cfm-120mm-fan-nf-p12-redux-1700-pwm
If your budget is tight, you could go with NF-B9's or F12 PWM CO's respectively instead.
