That piece is so terribly small I think I'd burn the whole thing up. I broke it right at the entry into the plastic fitting unfortunately. Thanks for the idea.

OK. Thanks.

Get a Bobby pin (packs are silly cheap) and cut the end off of it. Or use a staple.

You could (?) get a repacement cooler.
 
Or get crimping pliers and replacement connectors. You will find all you need at Radiospares for example. But it will cost you a lot.
 
Or get an old GPU cooler, cut off the mini 4pin connector with some wire length, replace yours (just 4 wires to be soldered). Solderings isolation with some shrinkable. Not a big deal. These mini connectors can also be found in electronics devices such as laptops, camcorders, etc.
 
You can even buy a wired connector : for example this mini 4 pin female to standard 4 pin male adapter (you just need the mini female connector and the wires) : http://www.performance-pc...-connector-female.html
 
Don't try to fix such a connector. Chances are you will destroy the male connector (on the GPU) when you plug it back on your graphics card.
 
 

No luck so far. Much more difficult than I thought. I'm down to the fan itself. Any replacements for this:
 

 
 

Might try that. Thanks. Any specific fan you have in mind? The plastic connector looks like it's specific for the male end on the pcb.

It is not a standard 4-pin fan and it won't plug into a standard 4-pin fan header. It uses a standard NVIDIA PWM fan connector though.

If you aren't comfortable fixing it, why don't you take it to someone who is? It's really not hard to fix. Either the existing connector can be extracted and re-crimped/soldered, or the connector from any other NVIDIA PWM fan can be spliced on in its place.

I used one of these when I installed an H55 and Kraken G10 on a GTX 780 so I could control the H55 via the GPU.

Thanks guys. I will probably ship it off somewhere for the repair. Just don't have the tools to fix it. I will probably look at my 580 too. Appreciate the help.

I offered to do it for him. I have rewired many cars, his problem should be a cakewalk !
 

Size matters not with the right tools and experience (or even related experience).  Even soldering 0.5mm pitch leads and smaller is easy.

EKWB cooler doesn't need any power... so if you are considering liquid cooling you won't have to worry about it.

Well, this is impressive. I installed the hybrid cooler on my top card today. Amazing performance. Idles around 27C and never went above 40C on load in SLI with the flight sim I usually play. I was seeing 31-32C at idle and load in the mid 50s before with the ACX cooler. The bottom card still has the ACX cooler which performs quite well but not as well as the hybrid cooler of course. The bottom card idles about 30C and is 47C with load.

Hope Dave can repair my screw up and send it back to me. I am hoping to install the second hybrid cooler as soon as I can. I'm quite impressed at how well the hybrid cooler works.

Didn't realize how well it worked. Won't go back to air cooling after this.
