My board offers 10 PWM headers, GPU offers 2 extra. I run my CPU on a 120 Radiator, one fan in and one out, the other fans never go on! Only on extreme use of the GPU, the Strix will turn them on slowly, not the extra 2 GPU Fan headers on OC! I removed all fans, temps stayed the same, 120 radiator i enough for 6900k on 4.6. That Strix is enough to bow air trough the hole office, but he never does that....
If you can find any USB C front panel case, go for that, i needed to build that my self, but i can recharge and update any USB C on full speed and full WATT 1600 Amp now, only old USB A on the back, no B what so ever.....
