Replace Heat Sink / Fan on 9400 GT Video Card?

Click for full size
Video Card with Heatsink Removed
Click for full size
Heatsink & Fan
On one of my friends system, I upgraded their video card. They had an nVidia GeForce 9400 GT. They now have RADEON HD 6570.

However, the GeForce card still works, outside of one problem. The fan on the heat sink no longer spins freely.

As you can see by the pictures, I was able to remove the heat sink / Fan unit from the board. I also took off the plastic shield over the heat sink as well to get at the actual fan.

It was very dirty inside (user is a heavy smoker). I got it cleaned as best as I can. However, as I said, the fan does not spin freely on its own.

If I look at the back of heat sink , I can see the following information on the back of the fan itself

EVERCOOL
Low noise. Long life time
HEAT DISSIPATION SPECIALIST
EC5010LL12E
EL BEARING
DC 12V 0.07A
CE
Quality Product

Would I be able to just replace the fan? I see the fan is attached to the heat sink with 2 screws. I did try to remove them, but they seemed to be stuck (and I did not want to try to much and strip them).

Or, would it be better to contact nVidia and see if they will sell me the unit (heat sink + fan)?

Thanks in advance for any help or ideas.

There's typically a sticker or plug on the fan that covers the end of the fan shaft. Remove that, then carefully remove the tiny E-clip that holds the fan onto the shaft. Pull the fan off of the shaft and clean everything with rubbing alcohol. Apply a drop or two of light machine oil and reassemble. The fan should be as good as new. I've fixed several in this manner and they're still in 24x7 operation several years later.

EVGA made the card so if you're looking for a fan replacement, I'd check with them. You can also replace the heatsink as well, this should fit on there.

Definitely try lubricating the fan first, I've had good luck with doing that as well.

Thanks for the replies so far.

I think for starters, I'm going to try the lubrication route. I know the sticker / plug that HarryH3 See Profile is talking about. It also does not sound like that hard of a process.

If that does work, I'll have to use the same technique on a power supply fan that has also died in my PFSense box. Sometimes it spins, and other times, it does not. I did not know you could do that to these fans to get them working again.

When I do this, I'll post back with my results in regards to the video card.

Thanks again,

Be careful, and don't lose that little clip! (I have, maybe three or four lost somewhere 'round my bench.) Once in awhile I find one with the vacuum cleaner, or a large magnet I sweep across the floor.

I pealed the sticker off the back of the fan, and found the shaft and the little clip. And yes, they are small, and I can see why they would be so easy to lose!

I took the fan out, cleaned it all out with rubbing alcohol, and then let it air dry. Once that was done, I took a drop of light machine oil and put everything back together.

In the process, I also cleaned off the GPU and heat sink of any old thermal paste (used the rubbing alcohol for that), and applied new thermal paste.

Once it was all put back together, I tried it out in my main system, and it works great!

Thanks again for letting me know of this little trick. As I said, I have a larger fan inside of my power supply that is currently running my PFSense box that is starting to fail. Sometime this week, I'll take it down and fix that one as well.

Glad to hear that you have it working again!

Good luck with the power supply fan. Sometimes the fans are installed in such a way that you have to remove a LOT of parts inside the supply to get to the fan.

Ha... just had to peak inside this thread to see if it was an EVGA card... of course. A long time ago I worked at an EVGA only shop... I really wonder how they have survived with some o the crap they have put out. Some models they told us... "oops, even if out of warranty by a month or two, we'll take care of it" which seems kinda cool except it was a model that ALL the fans failed on within 6 to 18 months and they never told customers that.....

Grrr... sorry, glad you got it fixed and I didn't mean to thread-jack.

Indeed! While I don't need the card right away, it is good to know that it is ready to go as a spare if/when I (or someone else) may need it.

As far as the power supply fan, I had it apart about a month ago to inspect it. I made a note for myself the make/model of the fan, and was just going to buy a new one. Now with the knowledge that I now have with fixing the fan in the video card, I won't need to do that. With my power supply, the fan was actually very easy to get to. Just had to take the case off the power supply, and it is right there. Unplug it from the board, unscrew it, and it pops right out.

Just wanted to give a quick update to this.

Using the same method, I was able to fix the fan in my power supply that runs my PFSense box.

That is a nifty little trick!

HarryH3 See Profile I again thank you for sharing that information with me.

Glad to help! So many things today are made so that it is nearly impossible to repair them. For the things that can be fixed, the fixes are often easy, once you know how.

Each one teach one.

Just keep an eye on the fans, as I have done what you just did on numerous fans in the past. You may find in a year or maybe a few months, that you'll have to repeat the procedure as the oil dries up.

I recall one power supply fan required a few drops of oil every 6 months or so... I got to be pretty good at tearing down that particular PS.
