chipset fan dead

[kinetek]

Looks like the chipset fan is dead. The heatsink is not adequate to handle the heat so I'll need something more. I found a fan at fry's but they didn't have any with the 2 pin connecter (I think these are rare). The plastic connector on my motherboard makes it so 3 pins don't fit (I think the 3rd pin is just the ground). What can I do?

I have considered just going with a larger heatsink but I don't know what's involved in replacing it.

I have a Gigabyte GA-7N400 Pro which has a nForce2 chipset

I found this fan. Do you think it'll mount on the heatsink?

If the fan at Fry's fits just clip the plug off of the old fan and solder the black and yellow leads on the new fan to the wires on the old plug.

Well, I'm a newbie but I know enough to get around inside my case and upgrade things. I've never soldered before and I don't want to get in over my head. Should I just get that 2-pin fan?

I highly recomend the following:

goto zalmanusa.com
go look up the chipset heatsinks. chipsets do NOT need a fan, they only do if the heatsink is tiny and lame. pull off and clean with alcohol and a qtip the old crap from the chipset if its not clean, and use a big assed heatsink that zalman sells.
those tiny fans make 3x more noise than most psu's do. and they burn out and get stuck on fuzz.

Actually if you the 7N400Pro2 Rev 2 board, is the same exact thing, with one of the exception being that the chipset doesn't have a fan. Chipset fans aren't really necessary. You don't have to solder anything, if you want to you could even just splice the wires together with wire nuts.

However what kind of connection does the fan have? Is it an actual PC fan, if so, just ignore the motherboard plug, and plug it into the power supply.

Your other option is to get a different heatsink for the northbridge, there are several to choose from, both with fans and without, normally they are under $10.

Usually 3-wire fans will fit 2-prong plugs by offsetting it to one side. The 3rd wire is for RPM detection.

I have some 40mm 2-lead fans here if you really need on that bad.

Thanks for the replies guys. I'm probably going to go with the zalman heatsink. Unfortunately there's a plastic cover around the pins on the motherboard that prevents anything but that particler plug from fitting and there's no 2-pin connector coming from my power supply either.

 

[Mr5oh]

When I said plug into your powersupply I assumed the fan you bought had a connector on it?

They sell adapters and such for this, but the Zalman is a much better choice anyways.

Oh, THAT kind of plug. I have some fans like that but I don't know if any are 40mm.

You could use a different connector, and connect a 3-pin fan to, say, the chassis fan header on your board, or a 4-pin fan to the power supply.

When i got my Abit NF7, I unplug the chipset fan immediately, and it has been running stable perfectly, I can even overclock it to 200FSB, so i would say chipset fan isn't necessary if you got an adequate air circulation for ur case

Sorry, I've got to ask, what was the point in that? Noise issue?

Exactly, Noise issue
I know that the chipset fan on NF7 isn't <i>that</i> loud at all, but since I've spending much time to make my pc quiet, even that fan is "loud" for me :redface:
