spanishflyer, nice system you have built, the video card you have supposedly runs quite and cool but cards with this type of heatsink dump the heated air into the case so good case airflow is a must, intake and exhaust fans that remove the heat will help a lot. Are you using any video card overclocking software like MSI Afterburnner. You can set a fan profile to increase the fan speed at a lower temperature than the video cards bios to keep the card from reaching those temperatures but you still need to expel that heat from the case.

Thanks a lot Menthol,
I will try using the MSI afterburner to increase the fan speed as you suggest.
The MSI GeForce I have only has one fan and exhausts the air through the back of the PC case, not inside and the Kraken CPU cooler is also pushing air via its two fans, through the cooler and exhausting to the exterior on the top of the box. Additionally I have a frontal 150 mm fan, and two 200 mm fans, top and side panel, all three blowing air into the case; the side panel one blows air directly on the Graphics card and the mother board. One last fan 150mm on the rear of the case that is extracting air from the case (tower type) NZXT Phantom 820. So basically I believe there is plenty of air being constantly refreshed in the case.
I do however believe that I can increase the speed of its fan on the GTX 980Ti and go from there (using as you suggested, the MSI Afterburner; what worries me that it starts becoming a bit noisier, and for that reason I have just found a kit EVGA sells, the EVGA Hybrid Liquid Cool for GeForce GTX 980 Ti for "only" $160 or so (possibly 50% more here in Spain...), but still cheaper than having to buy the whole GeForce from EVGA....

Still I will try out the fan adjustment and see how it goes.

Thanks again and best regards,

you may be able to return the card citing overheating issues and get the water-cooled one after?

what are warrantys for 😛

Thanks for the suggestion Keller1234, I know I can do that, but it will be too complicated and what is worse, I will have to return this one and wait for ages till I get the water cooled one; the supplier is in Germany.

However in the mean time and using MSI Afterburner I have adjusted the GPU fan to run at max speed when reaching about 70ºC and have managed to cool it down a bit.... but the fan noise is totally unacceptable.

I have as I mentioned above found the EVGA kit and I'm going for it; plenty of room in my Phantom 820.

Will keep you posted.
