Built my pc yesterday and its been going great, although when ever i start the machine the back fan rattles for about 3 seconds, then whilst the computer is on every 5-40 mins there will be another short period of rattling, the rattling when the pc is on it almost un-noticeable though. Any help would be greatly appreciated

Thanks
ps. im not 100% sure its the fan but i think it is.
 
Well, open up the case and see if there's any wires in the way of the fan, that's usually the cause of rattling.
If not, its possible your fan is defective, there are two things you can do.
- Replace the fan outright
- Lubricate the shaft. Which you can do by peeling off the information sticker, then removing the small rubber cap that should be there. In there should be the shaft, and at the bottom there might be a plastic or rubber ring. You have to get a pair of tweezers or something to lift that ring, then apply lubricant under there. If there is no ring you can just apply a bit of oil directly. From there you put it back together and hopefully the sound is gone.
If that doesn't work, just replace the fan :p.
