Aftermarket cooler for gpu fans won't spin

[kupic]

Hi,
I recently purchased and installed arctic accelero xtreme 3 cooler on my gigabyte r9 290 windforce graphics card due to high temps (around 94 degrees celsius), throttling
and loud fans. I chose the ac3 following Tom's guide for the r9 290.

Now after the install the pc boots but the gpu fans won't spin. Pc utilities read crazy number rpm or at times 0 rpm on the gpu. I connected back the stock cooler while keeping everything together and the fans spin.

Do I have a dead ac3 or is there anything I can do?

Thanks

You should've tried Afterburner and cranking the fan speed up. If you have a spare 3/4 pin extender or Y splitter you don't mind destroying, then get a knife or something thin that you don't mind getting a bit black and warm it over an oven then cut off the walls around the pins of the plug so you only have the pins sticking out, then get the plug of the cooler and match it with positive and negetive, the pins will going a bit tight because the cooler connectors are small but they will go in, then you can plug the another end into your mobo fan connector.

I have a dedicated extender that I modified this way to test old fans and coolers that I buy off ebay before re-selling. It works really well.

Yeah I read about connecting it through the mobo but I contacted the manufacturer and they said to plug the fans into the PSU using a 4 pin adapter (12 volts). Fans did spin.

Support said : We believe that your graphics card has semi-passive feature or controls the fan by voltage (spin base on RPM) or using different PWM programme, therefore the fan doesn't spin if you plug it to your graphics card. For instant solution, you may simply keep plug the fan to your power supply.

Is this a good enough permanent solution? To be fair I'm running the card at 60 degrees celsius instead of 94 now...
