<div class="bbWrapper">I decided to replace the N75 and bought the used one for with £20. While I was taking out the old one, a piece of it remained in my hand as soon as I touched it. There was probably a crack at the joint and it was causing the noise. It's running smoothly at the moment... It seems like it contributed to the performance as well...</div>
