A few random computer questions

Like I said, i have a few random computer questions that don't deserve their own post in the proper section.

1) I have those "mod stickers" on the front of my case. I used them to keep track of what all had gone through my case but now I have to many and i'm starting to peel them off. Not all of them come off easily and most of them leave half of themselves behind. What' the best way to get the remains and the sticky spots off from my case? I was thinking Rubbing alcohol. Btw, the stickers are all on a plexiglass portion.

2) Overclocking - I set my voltage to the max sometimes (and work down). The max is 1.5625 or something like that. CPU Z only records my CPU going up to 1.44v, why is that?

3)Voltage Calculator - I was looking into getting a PCI slot fan (or 2) but I don't already have a lot hooked up to my PSU. Is there a program that will monitor how much power my computer is using?
 
1) Rubbing alcohol should do the trick.

2) The difference between what you set in the BIOS and what you see with CPU-Z is due to vOffset and/or vDroop. vOffset is simply the difference between what you set in the BIOS and what your motherboard supplies to your chip for idle to light operation. vDroop is the difference between voltage at idle and voltage under full load. Both are intentional safety measures set in place by many motherboard manufactures. Some performance boards offer a BIOS feature to disable vDroop, while on others boards, people have discovered that shading a particular resister with a pencil disables it completely. Whether or not it should be disabled is a strongly debated topic.

Note that setting your chip's voltage to it's maximum operational value and working down from there is a very poor way to overclock. Not only are you causing your chip to generate needless amounts of heat, you are placing an undue amount of stress on your motherboard's chipset and power management system. This can cause long term damage to your cpu and/or motherboard unless you are absolutely certain your have cooling under control. Furthermore, most find much more success in reaching a stable OC by working up rather than working down. Several reasons for this is that it's much easier on the chip and motherboard, and it takes into account the fact that the relationship between achievable OC and voltage is linear to a point, and that it then becomes exponential. If you're starting in the exponential voltage range, you may not have a good sense of how far your chip will go. It's best to first see how far you can push it at stock, then explore the linear path. Once you've found the speed at which an additional increase requires far more voltage than a previous increase of the same amount, you'll have a good sense of whether or not it's worth it to pursue further and whether or not your cooling is up for the task. Now this whole spiel may not apply to certain older rigs, but its the practice I've always followed regardless of the chip used.

3) I would imagine something like that is readily available, but I don't know of any programs or tools off the top of my head.
 
Ahh thanks.

Some of the glue didn't come off so I used a screw driver to peel it up. I can see this little scratchs when the light hits it a certain way. Obviously since they're not a big deal i'm not willing to spend a lot of money but I thought i saw a product out there (a liquid) that is removes scratchs on glasses, Wouldn't this work for Plexiglass and what's the name of it?
 
About the OC voltage, that's something called vdroop. Depending on the quality of your mobo and psu, you could be giving 1.5V to your cpu but by the time it arrives there there are losses and you'd be getting less.

All components get vdroop. Some components might be better quality and you'd be getting less vdroop.
