We did some further investigation about cooling the Vitec inductors and confirm that operating temp range is -40 to 125C.

These do get hot, and it is perfectly normal. The amount of ventilation provided by the stock cooling solution (the component is located under the fan inlet) is equivalent or less than that described by several posters in this thread.

According to our informed sources, there is simply no need to sink these components, and required cooling is none other than a mild air circulation around the card.

the crashes reported in this thread are occuring for other reasons. software? overclock ?
