Hi, I have dell vostro 3750. I changed thermal paste few times, but I think is still hot. Also my hdd is died few weeks ago. So I wanna ask, can bad hdd rise cpu and gpu temps? I use arctic silver 5, somewhere heard, that is good choice, but I don't know that is good for copper - aluminum cooler frame? Also how much paste I should apply on cpu and gpu cores? One say that enogh rice dot, other apply much more on and around it?
