ASRock N68-VS3 UCC and NVIDIA GeForce 7025/nForce 630a

Is there a way to lower the temperature of NVIDIA GeForce 7025/nForce 630a? I don't use this in-built video card but it is so hot that it seems it is going to burn.

For optimal cooling an aftermarket heatsink/fan combination is best.
You will need to remove the stock chipset heatsink and install a heatsink/fan combination that will fit the existing heatsink's mounting holes.

Another option is to buy a 40mm fan and mount it so that it blows down and/or across the stock chipset heatsink.

Thanks. I don't like additional fans as it produces a lot of noise. I might install the heatsink alone though. It is weird there is no way to turn the in-built videocard off.

I had to start using a heatsink. it helped a bit. I don't get though why there is no way to turn the in-built video card off on these ASRock motherboards.
