[H]ard|OCP has posted a short and sweet review of BFG's ThermoIntelligence cooling technology. ThermoIntelligence is BFG's attempt to improve on Nvidia's stock cooling designs. Did they succeed? You'll have to read the article to find out.
There are two BFG graphics cards availbale right now that use ThermoIntelligence. They are the GeForce 8600 GTS OC (BFGE86256GTSOCFE) and the GeForce 8600 GTS OC2 (BFGE86256GTSOC2FE). The OC2 model is currently available at Newegg for $249.99 which is $30 more than the stock cooled (yet still overclocked) BFG 8600 GTS.
