E6600 fan dying

[Passa91]

My work PC has a E6600 with 2GB RAM, Gigabyte DS3 mobo and a GeForce 7300GS.

It has recently been turning itself off (after a period of a few hours to a few minutes usage). At first I thought it was the PSU (500w Antec Silentpower) so i swapped it out for a generic 500w PSU.

Well, while I was using it today, I put in speedfan and watched in amazement as my CPU reached 100 degrees and it didnt turn off. I opened up the case and it seemed the fan wouldnt start, speedfan just said the fan was going at 400,000 RPM.

At startup though, the fan starts up and cools it down to 30ish, by the time i boot into windows its around 22 degrees. But then the fan starts spluttering, visibly speeding up and speeding down in quick succession before it stops completely. A hard reboot (turn it off completely, then turn it back on) starts the fan back up again, and the process repeats. The BIOS shows the same temp as Speedfan (100ish after a period of usage) so speedfan is accurate.

Any ideas whats wrong? Its a work PC so I really need it fixed (do you think its worth ruling out the PSU? should i stick the antec one back in? should i try changing the powerboard its connected to?)

Thanks

Did you remember to put a heatsink/fan on that cpu? :laugh:

Honestly, I can't understand what you are talking about. Maybe you need a new fan? Good luck with that.

Did you even read his post??? wow man.

Anyway, sounds like your fan settings in the bios may be off. Also try plugging your CPU fan in a different header.

Different header? There is only one 'CPU FAN' thing on my mobo. Also, the setting in the BIOS must be on, the fan spins up for the first 10 mins of use or so.

The fact that the fan works normally when the machine boots makes it sound like a motherboard issue. Try setting the "FAN Speed Control Method (as shown on page 42 of the DS3 MB manual) to "Disable". If the fan runs normally on that setting, it's your MB causing it to misbehave. If the fan doesn't run flat out on that setting, you may have a faulty fan.

Carefully touch the heatsink while the pc is operating, if it nearly burns you then replace the whole heatsink fan unit with a newer and better one.

I found a stock intel heatsink and fan on ebay:

It's a so-so performer, but it is very cheap and gets the job done. Plus there should not be any issues in regards to warranties.

Browse for your self, just look for the one with the lowest shipping rate and purchase price.

I know you can order new fans for very cheap direct from Intel via phone or their webpage. I forgot the url, but will post it when I find their replacement parts catalog.


EDIT: Their prices have skyrocketed! since I last checked it out replcement HSF's cost less than $5-6 and fans were $2-ish. Yikes!

..I adjusted my DS3 bios to leave the fan on continuously rather then the default "smart fan "function.

If this was a retail boxed processor the whole thing should be covered under warranty: Information Needed for Warranty Processing.

That's a good idea. Try plugging the cpu fan into a "chasis fan" header. See if that helps, if it does, it's probably a BIOS setting.
