In your previous post about the same question i didnt consider it being a controlled fan, i was thinking more along the same lines of a case fan, plugged into the same p/supply with no sensors

Fans are controlled by heat sensors - when they reach the threshold temperature, they turn on. The sensor and fan can also be affected by dust.

Turn off the computer, open it up, and vacuum out all the accumulated dust in all openings you can see. Using a can of compressed air (from an office supply store), blow, vacuum, and wipe until you got it all cleaned out.

With dogs and cats in my house I need to do this every month or so.

Also, make sure the computer is in a spot with plenty of airflow around it. Locked up in a cabinet or in a corner on the floor does not allow good air circulation. Consider putting it on a box to raise it up about a foot off the ground if you can.

Finally, you may want to install SpeedFan It's free, and a great monitoring program for all devices. There are many tips on the site for dealing with temperature issues.

Speed fan will also tell you the performance status of your drive, including an estimate of when a failure may be coming up. It's possible that if your drive is on the verge of failure, it could be generating heat. And it's possible that an overheated computer could shorten the life of all the components, including the drives or CPU.

By the way, the only hard drives that have fans are either external drives, or if you've added a special fan. Otherwise the computer usually has 3 fans - one for the CPU/Heatsink, one in the Power Supply, and optionally a case fan for general cooling.

I hope that helps - if so, please rate my solution, if not, please post additional questions to this problem and I'll continue to help you resolve this issue.

Good Luck,

Fan noise

Hello. Your statement is FAN NOISE. If you are asking information about the 500GB hard drive, there is no fan IN the hard drive. If you are asking about a fan on a motherboard or case, then those can become dirty and need blown out with canned compressed air. The bearings can also be worn out after much use and the fan(s) would need to be replaced with the same new.
Hope this helps..

My laptop won't start... please

Not sure but it sounds like the hard drive is causing the problem. Lap tops are set up so that any problems with them they shut down, and a bad hard drive will shut you down the way you are describing. The only test i know for this is to remove the hard drive and see if you can get the computer to at least boot. If you can with no hard drive then it usually means the drive has failed. Not sure if this will help, but hope it helps.

Just got a new 3 games for my 360 and now it shows E68 along with the red circle eye or death lol. Can't play my game please help

Hi Chris

E68: Hard Drive Error - Hard drive not DMA configured: It could be a problem with the Hard Drive itself or a problem with the internal connection to the hard drive, Try removing the hard drive and playing without it. Also this can be caused by a problem with the fans that make them draw too much power, it can also be caused if you have unnecessary accessories attached to the console like an external fan unit. Attempt to remove unnecessary accessories first, and then necessary components such as the hard drive and USB devices. If you have any case mods you may want to investigate those as well.

check if after removing the drive if you still get the red light error or not, if the red light issue still prevails please send your console to MS support for repairs

My computer makes a loud noise,how can I fix this problem please?

there are a limited number of things that could be making noises. take off the cover of your computer and listen close when you start it. A fan would be the first thing i'de suspect. check them all- cpu fan- motherboard fan-videocard fan- powersupply fan.
I would also listen to the powersupply (rear top of computer)
only things left to check that could be making noise are the cd/dvd rom, floppy drive (both wont run without a disk in them) and your hard drive which would be the last one to make noise. the hard drive runs everytime your computer moves data, if it is getting loud, i would suggest backing up important files and shopping for a new one. Post again here if I can be of further assistance.

I hate to say this but it sounds like your hard drive has crashed. I would purchase another for about 80 dollars and reinstall windows.
