Been presented with a Gigabyte HD 5870 with 1 noisy fan.

Model is T128010SH
12v 0.25AMP
It has 3 wires.

There are a few used ones on ebay but I already have one of those.

Anywhere to source one locally?

Might find something on DealExtreme that you can adapt

Maybe, but it will have to match in with the second fan or I'll have to buy 2.
Interesting, 1 fan has 3 wires & the other has 2.
Same part number.

Get the one with 3 wires, it's the RPM readout for the sensor.

If this isn't present, the card will probably think the fan has failed and refuse to operate.

Yes it's the 3 wire one thats crook.

Here is the same fan, only with 4 wires.

4 wires means it has an onboard PWM controller.

You could probably use the 4 wire model and just leave the PWM control wire disconnected.

Might have to go that way if a 3 wire dosent come up.
Would have to hack into the wiring though as the plug will be different.

The contacts that are crimped onto the wires should be removable from the plastic plug, you usually just need a sewing pin\needle or such to lift up the plastic tabs that hold them in place and then pull the contacts out.

So, you could probably swap the plugs around and then remove the extra wire.

OK, but I want this to finish up so that the GPU will still control the fan speed, as it did standard.

It still should, without the PWM wire connected the fan should operate as a standard fan and any external control should still apply.

There is another seller on ebay who has some new fans.

http://www.ebay.com/itm/180895754745?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

There are both 2 & 3 wire.
They have the same part number but are 0.20Amp.
Was wondering if a pair of those work.

As long as they are the right size and same voltage there would be no problem.

The fact that it apparently draws less current is irrelevant, unless it spins significantly slower than the old one.

OK, I'll grab a couple of those. Better off with new ones & not much dearer.
Be interesting to see how long they take to arrive.

From my experience with eBay and Chinese sellers, it could take around 1-3 weeks, usually 2 weeks, but occasionally as long as 6 weeks.

But do they work?

You can never be too skeptical about cheap stuff from China...

Wasn't much choice. Can't buy them here.

I know, I've bought replacement fans on eBay too, and they worked, but given the nature of the vendors, I would always test them well beforehand

Not a lot... But there's the big name stuff you can be pretty sure of, like Asus, Enermax, or such

Have fitted the new fans.
Put it into a system & is working fine so far.
