The Inno3D iChill GTX 275 with Arctic Cooling Accelero XXX cooler performed great in testing, and being factory overclocked definitely helped. The temperatures never got close to reaching 50C, and the fan noise was bearable even at 100% as it was nearly drowned out by the case fans. There is more headroom left in the card for overclocking. The great core cooling and quiet operation are superb features of this card, especially combined with the stream processor power of the GTX 28x series cards. The 55nm design of this core paired with the massive Accelero XXX combined for an extremely cool operating temperature while loaded.
