[Resolved] NB Fan

Posted 20 October 2008 - 11:32 AM

I recently repaired some parts from an old computer (Building a basic storage server) and the AGP fan was barely working and making a lot of noise. I removed it cleaned it and lubed it with WD40 and it seems to be spinning a lot better, but it still makes a ton of noise clicking and vibrating.

Basically since it has a heat spreader and the heat in the case should never be excessive, do I really need this little fan, or can I just make sure to have enough case fans to compensate?

@KYA:
Back in ye olde days (1997), there used to be this standardized motherboard slot for graphics cards called "AGP" (Accelerated Graphics Port) that was better than PCI graphics card. An AGP slot would sit right next to a PCI slot, and had the same-size cutout on the back of the case. That was in the ancient times before the PCIe coup of 2004.
The AGP fan piggy backs on an AGP card.

@William:
I would find out the acceptable temperature range for the card, and how hot the card runs right now, and then take it off and see if it noticeably increases. You can always put it back on, right?

i'm still running an agp card that work fine for most games although i'm gonna need to get a new one now that they've started using new levels of pixel shading. Dreading the change, new graphics card means new mother board means new cpu means bankruptcy

Oh ok, thanks for the explanation. I thought it may be like a PCI slot case fan. Most graphic cards come with their own fan nowadays.

:crazy: I was under the impression that this was the 'broken fan' he was asking about.

he is isn't he? or did I completely miss something?

and in answer to the question (well my two cents worth) I would keep the fan, my radeon tends to get pretty hot even with its fan and when that fan isn't operating well(ie cleaned and lubed), the card tends to cause quite a bit of trouble

I had a similar problem to the clicking fan thing. I sent out my 8800GT for RMA and the one they sent me back would click at a low fan speed. Easy remedy: Download RivaTuner and manually set the fan speed to 100%. For some reason, when it's spinning that fast it doesn't want to click :/.

It's possible you just can't hear it at higher speeds.

It is not the fan attached to the video card, I guess I described this badly.

Since the casing appears to be different on each side, I flipped the fan over and it makes less noise, if I don't screw it in all the way, the noise is pretty much gone, but of course the fan is now blowing air onto the head spreader, instead of away from it.

The mobo does not have onboard graphics.

My boards ( Gigabyte GA-7VT600 ) have the connection for the fan but it is only a heat sink on the KT600 chip.

The clicking is the bearings worn down. Cleaning will help, vacuum ( WD-40 not recommended ) but will never fix the bearings. Replacement is best but trying to find one may not worth while.

Pushing the air onto the heat sink will be fine. As long as the heat sink gives up heat.

That's the northbridge. :)

On that board, you can almost certainly take it off and be okay. I've seen some NBs get really hot, but IIRC, VIA chipsets, at least the older ones, like you've got, don't have that problem.

I'd monitor it when the fan is off just make sure.

Speedfan should be able to monitor NB temps.

thanks, that helps a lot, I'll remove it in a day or two.

I could build a computer with my eyes closed, but ask me what some specifics are and i'm out :P Though, I actually should have known it was the NB. Thanks.
