Galaxy GeForce GTX 470 GC Video Card - Temperature and Sound Tests

Temperature Tests



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.




The fan from Galaxy might not look like much, but the cooler design does a great job of dropping temps. You have to remember the GTX 470 isn't the second bar, but the top one, so we're seeing a drop of almost 10c.


Sound Tests



Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.


After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).




The best thing about this drop is that it's not coming at a increase in noise; instead it's significantly quieter at load which is fantastic.
