I will try putting a fan on the card just in case.
If all this does not work out could buying a PCI Express sound card make any difference?
I am thinking, in another post found that my motherboard my HT link is only 1000mhz. Just thinking with an AM3 processor in it could it effect the sound card? Seen as all data travels on the bus there could be delays due to all the devices demanding bandwidth?
So thinking, a PCI-E x1 is faster than a PCI slot, meaning it should get more bandwidth?
