Utterly depends on the CPU or GPU being used. For GPUs it's not too much to increase them, but you can't increase them much. For CPUs, it's not too much unless the voltage needs changing, when it rises dramatically.
Good because I already overclocked my 4830 alittle and I plan to overclock my 2.8Ghz 5400+ to 3.0Ghz.. no voltage change just a quick boost... I know this will increase the core temperature but would this increase the Mainboard temperature(Temp1 on speedfan)too? thanks
Possibly, but not by much. Same rule applies - volts are what really pushes the power consumption (and therefore heat) up.
Do you think i can hit 3.0ghz without changing anything but the FSB to 214 or leave the FSB at 200 and raise the multiplier from 14 t0 16? I want to get as high as possible without messing with vcore or ram.. (too confusing)..lol
Even if the multiplier goes that high (I don't think it does), the CPU will need a higher voltage to reach 3.2.
Well, with an AMD, what is easy varies quite a lot. All I can say is try it, if it doesn't work, raise the voltage.
just to be safe, how many watts will one or two notches up on voltage add, because I dont want to overload my 400w corsair psu. all my temperatures are cool after being on all day and night... I just dont want to blow my PSU
Depends what the notches are, and what the CPU is, and even so, I wouldn't know the exact answer, I'd have to make a very broad guess. What I will say, is that as long as you have a single 6-pin graphics card (i.e. anything up to HD4850 in performance, but not a G80 8800, or a 9800GTX/GTX+, or an HD2900), a 95W CPU can be overclocked considerably on a Corsair 400W without trouble. If you do have a 12-pin or 14-pin graphics card, I'd take it easy.
Sounds like you could use standard on/off switches from radioshack...just make sure you are switching the "ground" not the "12v"...just leave the 12v connected all the time. (Do not get switches with LEDs in them; they are not designed for switching ground.) Also, many LED fans have the LEDs mounted so you can get at their leads. If so, you could probably wire the switch to the LED, so you could turn the LED off while leaving the fan on (or if you don't want the LED at all, you can just clip the leads and remove the LEDs) Just remember...NEVER SWITCH 12V, 5V, or any other V in your PC; switch everything with ground.
