Am I worrying too much? (PC related.)

Yeah no worries. If your fan noise is too loud you can also change out those stock fans with any number of great after market fans for your CPU and GPU. Usually those fans that come with are small inexpensive 80mm fans. Same goes for your intake and exhaust fans. Personally on my PC I have 2 120mm fans that came with the case for intake and exhaust. I purchased an after market MASSIVE and I do mean MASSIVE CPU cooler that came with a 120mm fan. My GPU is also a really nice upgrade from the standard shipped cooler as it 1), is very low profile, 2) dual 120mm thin fans and 3) came with an external dual fan adjuster so I can personally turn up or down either fan to help with not just noise but boost cooling as needed.

Here is the GPU cooler I got and here is the CPU cooler I got. Scythe products imo are amazing and my PC runs quieter than my laptop. The loudest thing in my box is an old a$$ PSU that I've had since 2001 xD lol. Still works so I'm getting my moneys worth out of it. :P
