With the TES 1326 Infrared Thermometer literally in hand we found ourselves getting real-world temperatures from the products we test at load (3D clock speeds).
There are two places we pull temperature from - the back of the card directly behind the core and if the card is dual slot and has an exhaust point we also pull a temperate from there, as seen in the picture.
At stock the GTX 460 runs a good bit cooler; the Cyclone heatsink that MSI offers is quickly becoming a personal favorite of mine for these mid range cards. When overclocked we see the GTX 460 does run a little warmer; unlike the HD 5830 not only are we dealing with higher clocks but also more voltage which is making it run slightly warmer. That extra voltage is only adding an extra degree to the GTX 460 Cyclone when compared to the HD 5830 which again is a testament to the cooler.
