Fast card with heat problem in SLI configuration

Have the card in December 2013, and for a few months yet another in SLI configuration. Degrees in the latter is the map (the upper course) extremely hot (99 ° in Furmark -> fan from Noctua NT-H1 WLP plan -> 85 °). As some have already written, also give my two cards Spulenfiepsen by itself what often ends in there that I get myself a gamble after prolonged tinnitus.

The performance, however, is terrific and when the card is operated alone, the OC spectrum not to be despised. However, there is no application / game that this really necessary unless 3D Vision or 3 monitor setups are used, then also worth the handle to the second card!
