Are these CPU temperatures safe/normal?

Hey guys,

I recently built my first rig using a AMD FX-8120 CPU and its stock fan. It's been working great, but the fan quickly gets really loud even during idle, so i thought I'd boot into my motherboard's bios screen and see how the temperatures progress.

When I start it up, the CPU temperature is around 41c and the fan is going at about 2072 RPM. But then within about five minutes the temperature has gone up to 46c and fan is at 5000 RPM. From there it started to level off, reaching 48c and 5625 RPM about 20 minutes later.

What concerns me is that these are the temperatures for when it is completely idle without the OS even being booted yet! Are these temperatures ok?
 
They're below max, which I believe is 61C.

Get a hold some third party temperature monitoring programs, like Speedfan, HWMonitor, or Core Temp, so you can view your idle temps when fully booted into the OS. Then, if you want, you can download Prime95 to stress test your CPU to get a good idea of max load temperatures.

Yeah I've been thinking of getting an aftermarket cpu fan, but I was wanting to make sure that none of my parts were defective because I am pretty sure that aftermarket fans void my cpu's warranty. So to confirm: I shouldn't be worried that my cpu or motherboard is bad, right?

Yeah, what is prime95? I've heard it mentioned a lot. What are the benefits of using it and could it actually hurt my pc?
