broken fan on Gigabyte GV-N460OC-768i

[soureel]

I bought this graphics card 4 years ago. Additional info about my system- windows 7, Dell monitor SP2309W, 8 gb RAM. The graphics card has been used for video editing and gaming.

Problem: one of the two fans has become separated from it's mount, causing the card to overheat. After a about 10 minutes of intensive gaming or video editing, the computer shuts down- I'm assuming because the card has overheated. I reattached the errant fan, but now that particular fan makes A LOT of noise when spinning (the 2nd fan is very quiet). Is it possible to repair this, or am I Ieft with the unpleasant prospect of replacing this very expensive graphics card?

If I must replace, I would appreciate suggestions. I am not in a position financially to purchase another one of these cards, and have a budget of around $130.

Thanks!

A quick search showed replacement fans available on eBay.
~$15

Start by defining the specs for the fans you need to replace. One easy way would be to remove the fan(s) from the car. The manufacturer's name and model number should be visible, either on the back of the fan, the top of the center hub or under any sticker on the hub. Another way would be to search for your graphic card model + fan.

That will allow you to search for that make and model or any direct replacement from other manufacturers.

If you can't find those specs, measure the diameter of the fan and the mounting centers and search for a replacement with these criteria:

1. Voltage: Most fans on video cards, heatsinks, etc. run on 12 volts DC.

2. Electrical connections: Do your fans have 2, 3 or 4 pin connectors?

3. Rotational speed (rpm) and air movement, usually in cfm (cubic ft.per minute). Many manufacturers also specify the noise output of their fans.

4. Bearings. For longevity and noise, ball bearings are usually better than sleeve bearings. Double ball bearings are better than single ball bearings.

If you have any stores that sell electronic, electrical or computer parts in your area, you may find one locally, or you can find them online. For example, check Newegg's selection of fans. You can narrow your search for the specs you want on the left side of the page.

Hope that helps.

thanks, helpful information. I've removed the fan from the board, but the 3-pin power plug won't budge. Suggestions?

I've found fans which are compatible with the GeForce 460SE. Mine is the 460OC. Does that make any difference when shopping for a fan?

That should work, but you only need one or two replacement fans, which should cost no more than ~$5 each, not a $45 cooling system.

I don't know if there are multiple makers or versions of the GeForce 460OC with different cooling solutions. If the fans are easily removed from the rest of the support system, just do it, and get the right fans.

In my first reply, I gave you the info you need to determine the make and model of the fan, itself, assuming it's visible. That should help you find a good replacement model. If you can't find an exact fit with the same or better specs, you could also try contacting the manufacturer's tech support for the info.

I was able to remove the fan assembly from the cooling assembly without any problem.

there is no make or model number for the fan assembly, other than the name "Gigabyte".

well, this has been a learning experience for me. Eventually, it dawned on me that I needed to remove the fan from the fan assembly and replace just the individual fan which had gone lame. Found the manufacturer name, model number on the fan and have ordered a new one.

thanks for your help.

That's exactly what I was trying to explain. :thumbsup:

thanks for your help.

You're quite welcome. Happy New Year.
