Case fans to cool a GPU

Hi i just ordered parts for a new build and decided to buy a used GPU (in Canada the price for the RX480 and 1060 are terrible and they don't seem worth it). I found a HIS R9 280X iPower IceQ X² Turbo Boost Clock 3GB GDDR5 PCI-E card for $100 CAD and it seemed like a good deal. The ownder had just recently purchased the card used as well, but didn't realize it wouldn't fit in his case properly (mine is a HAF 932 so no worries)

He st the card up and showed it working, seemed fine. However one of the two cooling fans for the GPU was not spinning at all even on a benchmark test. He lowered the price to $55 CAD and said i could probably replace the fan. Well I took the risk and bought it. I'm still waiting for all my other parts. It seems like it will be a hassle to actually pay for the parts and replace (im sure its easier in the USA).

What are my options? I don't care how my card looks; I am interested in it functioning well and be cooled well.

So my thoughts on what i might do:

1.If the temperature doesn't get too high, can I ignore the problem? I am unsure if the average temperature of the card can be monitored for safe operation while only one side of the card is being cooled.

2. Buy replacement parts and fix the problem. I see this as being very costly (Canada).

3. Buy an aftermarket cooler. Thisis costly where I am.

4. Use case fans in some configuration to cool the card. Perhaps i need to remove the shroud from the card. I am most interested in this option.

Anyone here have experience with a hack or MacGyver solution using case fans to cool a graphics card?

You do not want to ignore the problem - it will probably overheat with just 1 fan.

I have upgraded the fans on a GPU before by removing the shroud and mounting higher-CFM PWM fans. All I had to do was screw the fans into the heasink fins, and splice the wires into the original connector. If you are mechanically inclined, this is a viable option, and you can easily end up with cooling that's better than stock. I used 80mm bgears b-pwm fans in my GTX 960 with great results.

Hey Scuzzy I happen to have a bunch of extra Yate Loon case fans. They are rated for 47 cfm and are 120 mm fans. I was thinking of using two of them. Do you think the 47 cfm would cut it?

Also, could I just have the fans run continuously and not have them powered by the GPU?

That would work, yes.
