Failing cpu fan

Hello. I've been having some troubles with my stock cpu fan. I have a
core 2 duo 6420 @ 2.13 ghz. When I shut the computer down the fan
doesn't start up unless I give it a manual push or restart again. I
can't find anywhere just to buy the fan. On newegg the cheapest decent
heat sink fan combo is 50 bucks.

I'm hesitant to spend 50 bucks on a older setup but I don't want to
junk it either. Any other solutions? I leave my pc on all the time and
seem to have a lot of problems with fans. Maybe I should look into
using sleep modes. Do they normally disable the cpu fan?

thanks

Hi,

The cpu and fan have a 3 year warranty. If it's still in that realm then
get in touch with Intel to have them ship you out a replacement. However,
if you're out of warranty you should be able to get away with a 3rd part fan
way less than $50. Take a look at the cpu fans and read the user reviews
from newegg.
I don't know your cpu form factor, but below is an example for $27
(shipping included)

I sifted through intel's site and found a number to call. New fan on
the way. I still have until june on my warranty.

thanks!

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.
 
Installed new heat sink/fan and it does the same thing. I'm thinking
it has something to do with the bios fan control. 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.

If you really mean "a few minutes", that might be a problem. If
you really mean "a few seconds", that is not a problem IMO.

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.

What motherboard are you using?
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.
