I busted out an Alienware m17 with the Dell standard 256 GB M.2 drive so that I could get the 6 cell battery. I have ordered a 970 PRO 512GB to go into the 2nd M.2 slot, but in reading the m17 service manual, I see that I'm supposed to order a heat shield when using both M.2 slots. 1. Is this really necessary? 2. If so, does anyone know the part number? (it is the same as what is used in older generations of the Alienware notebooks? Thanks!
