CPU fan getting loud with basic usage (web browsing, youtube, etc.)

I built my own PC a few months ago and the CPU fan has always been loud right off start-up, but can get really annoying once I do anything slightly cpu-intensive with the computer.

Here's my full parts list: http://pcpartpicker.com/user/rino757/saved/JmH2FT

Though I ended up using a different PSU and case.

The CPU is really high end and I'm using the stock fan, and my case only has one fan, so I understand that it'd get hot in there. I don't have the money for any upgrades right now aside from possibly another case fan or two (definitely no liquid cooling.) I haven't overclocked the CPU and the thermal paste is on right.

I'm wondering if there's some way to make it so that the CPU doesn't use it's full potential for every thing (maybe undervolting/clocking?) so that maybe it'll stay cooler.
 
Solution
Drop the CPU down to 3.0 Ghz with multiplier adjustments and then drop the voltage bit by bit booting in to windows each time and running stress testing software to test for stability. Continue doing this until the PC crashes and the raise the voltage 2 settings and call it good. However a Coolermaster 212 Evo is only like $30 dollars and will allow you to actually increase performance by overclocking while drastically reducing noise and heat.

Really, I can't buy a new cooler. I'm asking for a software solution, not a hardware one.

The only "software" solution to this would be underclocking/undervolting the CPU to reduce temps. This will also reduce performance. You can try using some better thermal paste, might make a difference. At the end of the day you have an 8 core 125 watt cpu under the same cooler that they use on dual core athlons, it's gonna be loud that is just how it is.

Considering how powerful the CPU is, shouldn't the performance still be good if not great even when undervolted? I don't really do anything with my computer (at the moment) that requires peak performance, and any games I play are more reliant on my graphics card which cools itself just fine.

If my only software option is undervolting, and if my computer will still handle most tasks fine with an undervolted FX-8350, what would you say is the best way to go about doing it? You don't have to give step by step instructions if you're busy. If there's a certain method you'd recommend that you can link that's fine too.
