Video card fan died on a galaxy 7600GS, need replacement. suitable one can be found here

http://www.directron.com/ec4510m12sb.html

Asked if they ship to NZ but dunno how eventful that would be, does anyone know anywhere in NZ I can get this fan (or a compatible one?) or if anyone has one they would like to give/sell to me?

I don't know if there are fans like that in NZ, but I have an idea:

Snap the housing of a 40mm fan and attach the bottom frame with superglue or something.

Pretty sure DSE have somthing similar. But if it was me I'd try Directron - the cost is low enough to risk it.

There products are availible in NZ. Do a Google search for NZ, just type in Zalman.

The VF900-Cu is a little overkill and expensive for a 7600GS, I think Agent_24 is looking for a fan replacement and not the entire heatsink fan combo.

Something like this (http://www.pc-look.com/boutik/Prod_Titan_Ventilateur-Blower-PCI-Slot-Cooler-TTC-003__8923_en.html?language=en) could be a good option, I've seen a fair few mods where they bend a PCI bracket 90 degrees and hot glue a 120mm fan to it. The fan then blow air up on to the video card heatsink. Would be considerably quieter than any 40mm or 60mm stock fan, you could even volt mod it down to 7v. This is all assuming theres enough space below the video card.

I asked them if I could order it, how much shipping would be and if I can pay with credit card: they replied with


"Actually, payment can only be by wire transfer for international orders. The shipping cost would be about 5 or 6 times the cost of the fan itself. If you had an American friend or relative who could buy the fan, then mail it to you in an envelope as a letter you'd be much better off. Or find a local source."

Funny thing is I just bought some CDs from CDUniverse (which is in USA) and they only charge you $8.99 USD airmail for first item + $1.75 or so each extra item. And they accepted my card.

Looks like if I did try to order it, it would be a lot of hassle...

Yes, That's why I was just looking at a new fan because that's easier, and I thought it would be cheaper.

Don't want to have to rip off the heatsink and redo all the thermal interface either, since to tell the truth I don't know I've actually ever been able to do it properly. (CPU HSF with the thermal pad already on is another matter :p)

And of course all the aftermarket coolers out there are huge with heatpipes or are much more overkill than needed. I mean who is going to sell a stock cooler??

All I just want is a tiny little fan! :badpc: Doesn't anyone import them??!

On another aspect what could I do to possibly repair the fan?

http://www.imagef1.net.nz/files/IMG_2002.JPG (sorry for the **** photo, seems the best I can do)

On first inspection the negative wire had come off (dry joint caused by heat from GPU?), but resoldering both wires had no effect

Resistance across whole fan reads about 1400K ohm (normal 80mm case fan was 400K)

the SMD resistor checked out fine at 47 ohm

Both windings seem to check fine at 54 ohm each

12v goes into the little 4-pin IC (or whatever it is, part number 276 609Gh, couldn't find it in google) on the pin furthest away from you in the photo, but nothing can be measured on any other pin. Not sure if that's a problem but as the 2 middle pins connect to 2 of the 4 wires coming from the windings, it might be.

I thought it might be some kind of magnetic sensor for RPM, but as the track for the RPM wire goes nowhere except to where it looks a transistor should be, I guess not.

apart from heat or just normal failure, my only other theory is that the bad negative connection somehow (how?, don't know) destroyed the IC

Anyone think of anything I might have missed?? (or If I'm completely off track) :lol:

Doesn't the entire fan assembly just unscrew off the heatsink? You could then just go for a replacement fan in its own chassis.

The fan does unscrew from the heatsink but doesn't have a chassis (or very minimal) it looks just like the one on the directron website, and mounts onto the heatsink with 3 screws on the underside.

Just for future readers of this post:

I have an ASUS x800xt video card that has a dead fan. When I called the RMA department and told them about it they told me their policy is to send out one replacement fan per serial number free of charge! (just the fan, not the whole heatsink/fan assembly) :clap

That's right, one replacement fan for free per card if it's an ASUS brand card.

Hope that helps someone...

Spam???

Given that it's neither Asus, nor x800xT Series.

I don't know.
