I think I found way to OC an nVIDIA GPU comparatively safely using nVIDIA system tools:
1)First, OC the GPU to a safe Core/ Memory bus frequency. For my GTX 260m with the Sager np8662, I OC'd them to Core/Memory - 620/950 Mhz.
2)Go to the "profile" option on the menu bar, and select "save profile", name it to whatever you want.
3)In the same performance tab, go to "Adjust custom rules".
4)Now, I'm going to deviate from the main topic a bit a bit, if you want your OC profile loaded at startup, click "load this profile" and then select 'At system startup' under "when these conditions are met". Then, Click on the highlighted 'Profile' on the right box, and select the profile you've recently created. Then, Click "Apply" and you're done. Your "Rule" should appear on the lowest box.
5)Now the real stuff begins:
a) Once again, select "load this profile" and then select "Which temperature is higher than xx degrees Celsius"
b)click on "Profile" in the right box, as done previously, and select the profile 'Sysdflt" and press OK.
c)Click on the Highlighted 'Which' in the right box and select GPU. Then, Click on the highlighted 'xx' in the same line and enter in a temperature you think is pretty high or borderline high(Preferable). Then select "apply'. It should appear on the 'rule' box at the bottom.
d)Additionally, using these set of rules, you can also program the computer to display a warning message and/or a warning tone if the temperature gets too high. For safety's sake, I did all three after OC'ing my GPU.
The point of all this is that as soon as the GPU temperatures go too high on an OC'd card, these rules will direct the computer to underclock the card to factory levels, which will reduce the temperature (And slightly, the performance) of the card after that point. Additionally,you can set your own custom profile and rearrange these steps if your card is getting too hot even after reducing to factory settings by setting the frequencies to something lower that factory settings. (Only if your GPU's getting hot even without OC'ing)
There, I'm not giving any guarantees, but in THEORY this should work....uptill now the temps of my OC'd card haven't gotten high enough to warrant this, i's just a safety measure on my part. I set the borderline temperature at 85 C.
You'll need nVIDIA system tools to do this though..Here's the link:

Under the performance tab, after installation, you'll have to agree to the disclaimer before you can use all the features. Many thanks to DRY_ICE who showed me how to overclock using system tools.
Oh and quetion: How do you select Shader Overlock setting using System tools? I can only acces the Core and memory Frequencies.
