    Alright. Computer troubles.

    1. The fin of one of the base fans broke off, the only connection it has is to a powersupply cord that is affixed to the motherboard connections. It makes a rattling sound when it's in operation.

    2. Every now and then a high pitched whistling down comes from the computer. It's none of the fans. Everytime I've tried to get close and listen it fucking stops. I've narrowed it down to my HDD's. Checked the healthy and they're all fine so WRY.

    Remove the fan and replace it? The rattling is more than likely the fan being off balanced because of the lost blade. >_>

    The whistling, on the other hand... Probably running at too high an RPM? Its the click you need to beware of! D:

    The fan can't be replaced because the lead that connects it to the computer is part of a set of powercables and other connectors with the case itself.

    I unplugged the hdd and the problem went away, huzzah.

    Is it leaning against something? Mine rattles when it gets to close to the wall.

    Did you try turning it off, and then back on?

    Is this the same fan you shove things in when you want quiet?

    I only did that once last night because I was trying to write. :) I have no idea when it broke.

    The whistling noise is generally indicative of an HDD spinning up and down. If you wish to eliminate this as a possibility, run a disk defrag. It may be spinning up and down because you have fragmented data, or it is using the HDD as virtual memory. Either way, a defrag is an excellent way to get your HDD spoiled all the way up to its maximum RPM. Also? Bittorrents work in a pinch (if you don't have anything but Windows' horribly slow defragger).

    Off-balance fans rattle until replaced. Most computer case fans are 80mm, and replacing it is your best bet. Tigerdirect.com and Newegg.com both carry them. Several companies also have new mag-lev fans which are noiseless and nearly friction free (http://www.newegg.com/Product/Product.aspx?Item=N82E16811999199).

    EDIT: one more simple/stupid thing to check for the whistle. Optical drives spin faster than anything else in your PC and are EXPOSED to the elements (whereas HDDs are sealed in a vacuum). Make sure you don't have a disk in there.

    HDDs are not under vacuum. They are hermetically sealed, but air is necessary to maintain the spacing between the platter and head.

    They are essentially hermetically sealed, but not quite. They have a hole with a micron-level filter which prevents any real net air in/out, but when your drive moves from various altitudes or air pressure changes, it has to change with it.
