If you paid with a Visa Gold or Platinum card or any American Express card, you should be covered until June, 2011. No such luck with Mastercard, which limits coverage only to original warranties of 12 months or less (and doesn't seem to provide very good service for extended warranties). After you get the replacement fan, you may want to clean the original fan, inside and out. Sealed ball bearings can't be lubed, but unsealed can be regerased (lithium grease only, not Vaseline). OTOH sleeve bearings should only be oiled (light machine oil, never silicone or WD-40). If the fan still doesn't start by itself, then it has an electronic problem.

When I first start the computer it will spin for a second and stop. I waited for a few minutes and as the cpu warmed up the fan goes on as normal. So I'm guessing it has something to do with the bios fan control? At least the new fan is a bit quieter.

You can look in the BIOS and find out. Fans should be started at a significant percentage of full speed, a CPU fan should be running at all times after startup IMO.

Check in your BIOS to see if you have an option for "Quiet Fan" or "Q-Fan (Asus)" or some other fan control, and turn that off or set it to "Always On" or "Full Speed" or whatever setting accomplishes that and see if it changes anything. |
