Increasing I/O voltage??? More question. Regarding temps

I was wondering if increasing the I/O voltage would kill any components in the PC?? I'm using a A7V266E now and just increased the I/O voltage to 2.75V. I'm able to hit 151Mhz FSB now because of increasing it. I'm just wondering what's the limit before I kill something as increasing it increments all the distributed voltage throughout the PCI and AGP cards too??

The normal VIO to PCI, AGP and chipset are at 3.3 volts.

You have increased the DDR voltage, from 2.5 volts. If anything, you will only fry the DIMMs as this voltage is independent of anything else. 2.75 volts is pretty safe. I would be reluctant to run the DDR DIMMs at anything higher than about 2.9 volts or so.

Is it me or something's weird about my pc. After I upped the I/O voltage to 2.75v and changed my FSB to 151 from 144 and running it a 1585 before and after the change of FSB, my temperature went up by 3 - 4c. I'm getting worried. I'm hitting the all time high of 57c. I'm using a SK6 with a YS tech fan(28cfm). Not sure why but my system never drops below 55c idle and hits 60c at full load. :(
