OK, I have a previously owned nc6000. The fan was always loud. But now I can barely hear it. Is that a good thing or a bad thing? Should I replace my fan or clean it with canned air? Yes I do use my laptop on my bed :(

Not sure what you mean by loud Hard Drives. Hard drives are so quiet you can barely hear them. If they are loud the only cure is replacement. However, I have never heard a hard drive that I would consider 'loud' in all my years in computing./ As you show a mirror fronted mac in your question - I think you may mean loud 'Fans'. This mac was notorious for its loud fans. They can be replaced, but I seem to remember a firmware fix from Apple to slow them down - or it may have been a 3rd party utility.
I have one of these and must say the fan noise is barely noticable, are they using a genuine fan? the original is speed controlled whereas a universal replacement would just run at full speed all the time.
I don't thing so, listen carefully the next time you are driving and see if you can hear what side it is on, If you identify a side the most lightly problem would be the wheel baring (runs through the centre of the hub). If it is the bearing, it will get progressivley worse and will need to be replaced. Good luck!
Your CPU fan should always be on while the computer is on. If it's off, your computer is going to crach in a matter of time. The noise is normal. If it's to loud, replace the fan. Nothing major. But it is normal for the fan to be loud. Thats a good sign it's cooling the CPU. But you can get a shfter 1. Your computer might over heat though. Good luck.
Sounds like the freezer fan blade is hitting on a build up of ice or frost. You may have a defrost issue, or it may be a one time thing, like the door was open for a long time (object holding door partially open) or also check the ice dispenser duct door to make sure it is closing. Sometimes a chunk of ice hangs up in the ice shoot, allowing moist air to enter freezer, resulting in the extra frost / ice near the freezer fan. You might also check the door gaskets, especially the bottom side where sugary liquid spills might cause a gasket to tear. #2: Long run times: If cooling is good, don't worry. Older refrig's often ran less time, but used much more electricity than the newer refrig's, even though new one run longer. (Like having a 40 watt light bulb on for 20 hours a day uses less electricity than having a 100 watt bulb on for 10 hours a day)
