Hi all, ive had a HAF-X with a Phanteks-TC14PE CPU cooler and aGTX 670 Windforce for a few years now and its always been a bit loud but given that so many fans were running etc I kind of just accepted it, but now ive just bought an Enthoo Primo and I tested the case fans without any components installed and it was very quiet, but upon connecting my CPU Cooler and Windforce it sounds like a leaf blower again, so its clearly one of those two causing it, I have the older model of the CPU Cooler that is 3 pin rather than 4 pin PWM fans so im wondering is the Windforce generally a loud graphics card? or should I change my two Phanteks CPU fans for PWM Noctua fans? one of them has to be the culprit as the noise before hand was a gentle hum, now it sounds like if I point my case at the ground everything will fly about!
so which of those two is most likely to be the culprit? thank you
