[SOLVED] Fan is making a start up noise, then disappears

[icyulkn]

The fan makes a not-so-great noise for about 7-10 seconds and then goes away. Can someone tell me if this is a sign of a failing fan? I have another day or two before I can return it. Thanks

What sort of noise: clicks, squeals, whirrrr..?

Could be a faulty fan but more likely just some inbalance until the fan gets up to full speed.

Maybe the blades are touching the housing or a cable and once full air flow is established the case and/or blades flex ending contact.

Power down, unplug, open the case. Use a bright flashlight to inspect the fan: Housing, blades, and surrounding area. Look for signs of contact or damage. Maybe some piece of debris in the fan.

Try gently wiggling or twisting the fan. Does the entire fan housing move in any manner?

Ensure that the screws are all evenly snug and tight. Do not over tighten.

Probably a bad bearing that causes vibration.

When I power down the computer and let the fan sit and then power up again it doesn't make the sound. When I leave it off overnight, it makes the sound.

I messed with the fans a little bit so we'll see what happens when I wake up in the morning.

Yes, what you describe is the first stage of the bearings wearing out. If it is within warranty, request a replacement. If you need a detailed explanation, post back here.

I fidgeted with it (all of the fans) and it didn't make the noise today. I hope this is the end of it (I'll let you know). I have no clue what it could have been. I spun the fans numerous times, messed with the wires just in case. I also messed around with the screws a bit as well. Time will tell.
