2 Very quick questions
1) I just bought a new cpu fan. I took my old fan/hs out. There's some old thermal greese smudged over the cpu. Do I have to worry about it? as in, must I clean it or do anything prior to installing the new cpu fan and heat sink?
2) I just bought a new SATA II hard drive. Though my motherboard does not support SATA II it supports SATA I. I know I have to use a jumper so that it can work with mine, but just out of curiousity what happens if I don't? will it still work or will it not?
