Temperature Testing
Since video card temperatures and the heat generated by next-generation cards have become an area of concern among enthusiasts and gamers, we want to take a closer look at how the PNY GeForce GTX 465 graphics card does at idle and under a full load.
PNY GeForce GTX 465 Video Card Idle Temperature:
At idle on an open test bench the GeForce GTX 465 had some pretty good temperature numbers, which makes sense as we pointed out on the previous page the card has solid idle power consumption numbers. We were seeing right around 50C at idle it a room that was pushing 78F, which isn't as bad as we expected here in the summer. As you can see from the screen shot above, the idle state
of the GeForce GTX 470 drops the GPU core clock frequency down to just 50MHz and the
memory clock down to 67.5MHz to help conserve power and lower
temperatures. The fan spins at 1430RPM at 40% rotation speed when at idle. This is identical to the idle characteristics of the GeForce GTX 470, so when it comes to fan noise and speed the two cards are identical.
PNY GeForce GTX 465 Video Card Load Temperature:
We fired up FurMark and ran the stability at 640x480, which was enough to put the GPU at 100% load in order to get the highest load temperature possible. This application also charts the temperature results so you can see how the temperature rises and levels off, which is very nice. The GeForce GTX 465 maxed out at 88C. The fan on the GeForce GTX 465 video card was left on auto during temperature testing and the fan speed is dynamic. This means that it will increase/decrease depending on the GPU temp and GPU load. When we hit the space bar to stop the rendering the temperature dropped. Since a 2D application was open the GTX465 video card wouldn't go back to a complete idle state, but as you can see the temperature dropped and started to level off around 75C in this quick and simple test.
