Any experience with stuck GPU Fans...
 
Specifically GTX 750.
Happened twice now; first time under warranty; second too late.

I've read I can simply take off the fans and add a drop of 3-in-1 oil or silicone oil?

Or do I simply pitch it and get a screaming fast 1080? :)

You can try a DIY repair if there's nothing to lose, but once a fan start to go, it probably wont have that much more life even if you get it going again. As makeshift repairs I have in the past cable-tied case fans onto cards. You can also try looking at the fan part number, or exact card model number, and searching for it on ebay as there are places selling replacements. Depending on price, it might be worth considering.

If you should get a new much higher spec card is a different consideration...

I have repaired many fans, but some can't be gotten apart without destructive forces. On many fans, the blades can be removed by releasing a plastic washer under a rubber plug, often under a label on the side opposite the blades. There may be other washers in a particular order on the shaft.

I use a grease rather than oil. I try to use one that claims not to migrate. I think oil is too thin and will dry out quickly. I have found many ball bearing fans that either wore, or were improperly built, in which the shaft spins in the inner race, instead of making proper use of the bearings. These will not last long before more attention is needed.

With fans that make it hard, or impossible to reach the bearings by label-pealing or hub-drilling, I have been able to insert a thin tube along side the wires to the motor, and get oil to the bearings from the side. This works best if you have the fan on edge so that gravity works with you. It has taken a bit of time and working the fan up and down on the shaft for the oil to infiltrate. Of course, you don't want to overdo it.
I have a squeeze bottle of oil which came with a built-in tube. Lacking that, you might improvise with a tube like those which come with canned air.

I found a system recently in which its gradually increasing unreliability (over a period of years, it's old enough to vote) may have had something to do with one fan needing oil, and another having a burned out winding (brown label, char beneath). This was a PC with 3 fans total. Case fan was ok, power supply fan stalled, cpu fan burned out. After one relube and one replace, its mean time to hang is 100 times better.

Unless you are running out of slots, or concerned about your power bill, fix the 750 _and_ get that 1080?

I have found success by replacing the fan on a graphics card, when age and dust stopped it from reliably spinning. :smile:

It takes some effort to disassemble and reassemble the card, and maybe $10-$20 for the replacement fan (you should be able to find a model number on the fan, once the card is disassembled enough for you to take the fans off). I'll let you decide if cost/benefit-wise that makes sense. :wink:

I understand your point about the value of one's time.

There are people like me, for whom these efforts are part of the entertainment value of having a computer. True, they are frustrating, and cause much cursing, especially if you have no alternate card.

I have dismantled more than one graphics card to replace the thermal interface material. Besides that, I am rather obsessed by fans.

Diff'rent strokes...:smile:

I have reconditioned two of the GTX750Ti fans before I found sources to get new ones, so it does work (at least for a while-YMMV).

The only sources I have found are:

I believe the original manufacturer is no longer making them. Good luck whichever way you go.

RIP
 
Seems that the fan started behaving for the last 4 days.
Until this AM when the GPU died completely.

Gosh, It all seems futile to attempt to offer more oil to bronze bearings that run hot long hours.
It bothers me to image that any decent GPU manufacturer would use crap fans.
I vote to replace with ball bearings, or I prefer, ceramic bearing fans, as have done many times with zero regret.
My favorite wholesale electronic store has a sizeable stock range in this country.
Interpret that to mean that the good stuff might be hard to acquire.

PS: I noticed this thread late, is it really entirely dead or just not enduring more than a short burst without operational cooling?

The first thing I noticed that morning is that it was no longer sending any results from the GPU. In the past when the fan was stuck it would still send results but much less; without cooling fans that GPU would do 150 vs 500 Ghz/Day.

Sadly it had gone 4 days without any slowdowns to this point.

When I looked at the GPU that morning it showed no signs of life; no fans; no LEDs.

Then I went into the NVIDIA GPU tool it gave me as message something like: "No GPU detected".

Totally guessing, I might assume something burned out and deemed it unworkable.
