I have the corsair c70 case. I dont understand how to mount the fans in between the front panel and hard drive bays. I have two 120mm fans. Are there some special kind of screws i need?https://www.google.com/search?q=corsair+c70+front+fans&biw=360&bih=264&prmd=sv&tbm=isch&tbo=u&source=univ&fir=99_VXE7xDk5jPM%253A%252CedYTxjkRk-XB5M%252C_%253BXPMZyyBZLrhK2M%253A%252CrRq--DvtIqoLpM%252C_%253BjMTy7NSXQD3rgM%253A%252CefmFribOBpvdAM%252C_&usg=__q-kG1-LtXm1hQTyMGZRu8eQjGbA%3D&sa=X&ved=0CCYQ7AlqFQoTCMq_3f_U-MYCFYG0lAodX6kO3A#imgrc=DFfAJEq3geAGJM%3A&usg=__q-kG1-LtXm1hQTyMGZRu8eQjGbA%3D
