just finished building my new computer, and i got a couple questions

[m1ke101]

1. is the fan on the back of the case supposed to suck air into the case or blow it out?
2. how do i overclock my processor? (im not interested in doing it at the moment, but later down the road i might want to give it a try)
3. how do i overclock my ram? i have DDR 2100
4. my multiplier right now says 100mhz X 12.. so its the 1.2 ghz its supposed to be. i was wondering, isn't it supposed to be 133?

1. is the fan on the back of the case supposed to suck air into the case or blow it out?this one blows warm air out of the case
2. how do i overclock my processor? (im not interested in doing it at the moment, but later down the road i might want to give it a try)the exact method depends on the motherboard model and on the CPU. In general, by raising the multiplier and/or the FSB.
3. how do i overclock my ram? i have DDR 2100by raising the FSB, and/or by lowering the ram timings in BIOS
4. my multiplier right now says 100mhz X 12.. so its the 1.2 ghz its supposed to be. i was wondering, isn't it supposed to be 133? the 1.2GHz Athlon is available as 100mhz x 12 or 133mhz x 9. you must have the former.
