I have a water cooled system and just got in my GTX 470 to replace a GTX 295 Co-Op.  After unboxing and plugging in the stock card (with it's air cooling, no overclock, and fans on auto) the idle temperature of the GPU is 77°C.

Current ambient temperature in my house is 24°C. 
Current temperature of my CPU and motherboard waterblocks is 24°C (no load and no overclock).
*My PC has 3 240mm fans and 3 120mm fans and the temps shown above with all fans at 100%

My old GTX 295 Co-Op under full load only hit 65°C (on air cooling) on this same system.

If I run ATITool and "scan for artifacts" to put a load on this new GTX 470 GPU, it tops out around 90°C.

Is it normal for this card to be so hot when it's unused?  What about the GTX 480?  Wondering if I should return it and grab a different card before I purchase a water block.

    If you are getting 77 degrees C, your card is actually not idle. Use nVidia Inspector and check what powerstate your card is in. It's for sure not completely idle, because the temperatures would be way lower.

    Things that could cause this is for example using two monitors.

    EDIT: To make a comparison. My system is idle right now, and I mean real idle. 2x 480 GTX cards and they are at 42 degrees C with 23 degrees ambient in my room. Fans are at 45% (so, actually stock speed for an idle card). This is in a Lian Li PC-P80B with all case fans at minimum speed.

    Thanks.  I've included a screenshot below.  The power state is P3.

    I also included Real Temp in the screenshot which shows that my CPU is running 36-40°C (rather than the 25°C I'm seeing on the motherboard readout).

    Yes.


    Well that explains your idle temps. The drivers keep the card in a higher power state when running dual monitors. One solution is to use MSI afterburner and use the default user fan profile. It sets the idle fan speed 50% and that will probably drop your idle temps by 15C. 90C under max load isn't bad. The stock fan profile allows that by default and the cards are rated for 105C.

    These cards respond well to water.. Mine idles at 36 an after 60mins of Furmark hits 59C top, ambient at about 28C..... dual monitor creates different profile as already mentioned, 90C on air full load is pretty good actually....

    That's definitely it.  I unplugged the second monitor and rebooted and the card is now running at 44°C (picture attached).

    Thank you all for this topic.
    I have exactly the same problem. 2 monitors and 77 degrees.
