What is overclocking? and how would i do it? And also, is it good for my cpu?

well i'm planning to have many fans in my case....2 case fans...one extra for my videocard...and also a hardrive cooler. And of course i would have the cpu fan. my computer is loud enough already! with all that noise i would need better/louder speakers for my computer! how come those sony computers with like 1.5 gigahertz P4 computers are so quiet? are they actaully kept cool?

and do those 80mm case fans actually help? they seem weak.
Chandler, as regards fan noise, a better designed one (read expensive) may prove to be quieter as I would expect the impeller to produce less turbulence and to be balanced so as to avoid vibration. But not always the case I expect!
Regarding the hot hard drive issue, mine run at an estimated 40 deg. case temp., which I'm not really comfortable with but I must assume they are designed to work correctly at that temperature. I really don't like to see electronic components running 'finger-lickin' hot' and have always gone to considerable lengths to ensure sufficient heat-sinking of generously rated components in any equipment I build, but if you consider that most semiconductor components-including CPU's can safely be stored in boiling water, are we all getting a little paranoid about temperature? In my P.C., I simply rely on the P.S.U. to draw air out of the case, and having blocked the rear vent holes, cool air is forced to be drawn in at the front ensuring (hopefully) no isolated internal pockets of hot air. This seems to work O.K. though, as the side plates always feel quite cold.
With a Gforce3, Pentium4, etc, etc, this simple arrangement may prove, of course to be inadequate.
Before anyone pins me for it, I am aware that thermal issues also have implications for hard drive bearing life, as well as the electronics, but as I stated above, we must trust that the manufacturers have designed around this.
That, as they say, is what I think! :-D My suggestions are what I would try myself. If incorrect, I welcome corrections to my rather limited knowledge. Andy.

about clocking...you know when you overclock u go 5 mhz at a time....when you underclock...do u still go 5 mhz under at a time or any mhz?

chandler44, Whenever you're making adjustments to the overall speed of your system, it's best to do it in as small increments as the BIOS allows. This way you run the lowest risk of damaging your hardware.
hotfusion, I'm interested in where you got your information that CPUs can be stored in boiling water - I've never read that before! (I'm not disputing it, just interested in the source
)
One point, though, if you actually ran your CPU at 100 degrees C, it'd probably last a week tops. Cooling improves performance because heat makes the microscopic connections between transistors expand, effectively producing tiny short-circuits. Hence there can be all kinds of odd error messages and reboots associated with a hot CPU.
Taking effective cooling precautions is not paranoid, IMO, it's a necessary way of preserving modern components, especially the newer AMD, Intel and GeForce chipsets.

i use to run m ge-force MX regularly...it just has a heatsink and thats it. And it would get fairly hot. Then i added a old old old cpu fan on top of the heatsink to cool it down a little..and it seem to cool it down just a bit. After around 2 weeks...the old fan on the MX broke so i took off the fan. Now my Ge-force gets "finger lickin hot" because the fan isnt there anymore. Now is this hurting my ge-force because it started out with no fan...then i added one...now the fan is off again? it seems to be way hotter with the fan off after i took off the fan. sorry if it sounds confusing i coulnd't put it any easier way =)
Did you overclock the MX? If yes, then did you overclock the cpu settings or the memory? If you overclocked the CPU settings, then that's probably the reason. If not, then see if you have built up dust on there. These things act as insulation therefore preventing the flow of cool air. -Feryl

looks like i built up a little dust. and no i didnt overclock anything. i guess i better buy that blue orb soon! thanks!
