Sparkle Calibre X460GAs usual, Sparkle is marketing a GeForce GTX 460 model as part of its Calibre range, which groups higher end products. Just a single variant is on offer, overclocked at 790/950 MHz against 675/900 MHz for the stock model. It has 1 GB of memory and is on sale at €190.
For this Calibre X460G, Sparkle has used the reference PCB with the Accelero Twin Turbo Pro from Arctic Cooling. This cooler is made up of an aluminium radiator and four heatpipes cooled by two 92mm fans. A small heatsink has also been placed on the senstitive power stage components.
The cooler sticks slightly out the back of the PCB and its heatpipes rise 3 cm above it, which makes the card quite a bit bigger.
Sparkle delivers its card with a manual, an invitation to join the Calibre Club, a CD with drivers, 2 double molex to 6-pin PCI Express power supply cable convertors, a DVI to VGA adaptor and a mini-HDMI/HDMI cable as an optional extra. A sticker on the box indicates whether or not the cable is included. If it isn't, a mini-HDMI to HDMI adaptor will also be included.
The card is guaranteed for 3 years.

Temperature and noise readings
This is confirmed by the readings. With a GPU temperature of just 61 °C in load, the Calibre X460G is the best cooled GeForce GTX 460 in this roundup. In terms of noise levels, it’s very much the same as the reference model in load but is not as quiet at idle.
With the Calibre X460G, Sparkle has brought out an excellent GeForce GTX 460. In spite of a 17% GPU overclocking and low temperatures, it doesn ‘t make any more noise in load than the reference model. The only small negative is that Sparkle could have calibrated its cooler so as to make the fans quieter at idle.
