Recently my computer has been fairly loud. I have an i7 4770K with an H100i(stock) cooler. Case: 300r, GTX 770, 8GB RAM. CPU speeds are at stock but I'm not sure why the fans seem like they're loud. I've been told the stock H100i fans vibrate a little which may be the problem but I don't think they should be that loud at stock speeds. Could it be that my CPU requires thermal paste?
