when my pc is under load, i hear my numerous fans change pitch, JUST A LITTLE, but i notice it. my pc is stable and all that... but is that slight sound change normal? or is my power supply getting a little tired?

Yeah it's temp control kicking in so the fan speed is increased.

Either that or you need to clean the dust and grime out fo your flan blades.

I'm thinking it's probably dust build-up. Pull your PSU out and take the cover off so you can really get in there with a can of compressed air. My old PSU started to behave strangely one day; I popped the cover off, cleaned out some pretty nasty dust bunnies, put it back in and all was well again.

Just in case it might be hardware related, download and install Motherboard Monitor. You can see just how your voltages are doing in case there might be some issue waiting to happen.
