Overheating GTX 460: from 45 C idle to 100 C load

I'm really in a bind.

I don't know if this is the right place to ask but I have been having some issues with a Zotac GeForce GTX 460 that I recently purchased and installed. The card's minimum power requirement is 450 W so I installed a 500 W power supply as well. (First time upgrading a PSU) I installed the driver for the card and made sure all of the power connectors were where they should be. And I proceeded to start up APB Reloaded (somewhat graphics intensive F2P game). Everything ran smoothly for about 8 minutes, until my monitor suddenly went into sleep mode and was stuck in that state and the only thing I could do was restart the PC.
At this point, I have run MSI Afterburner and watched as the GPU temperature gradually climbed from 40~50 degrees C (idle) to about 100 degrees C (with load).
Why is it getting this hot?
Is there anything I can do to alleviate this issue?
This card should easily be able to handle this game (and more), yet it heats up so quickly that I am not able to do anything.
Even during the installation I made sure to remove all of the dust from inside the case.
Could it be a defect in the card?

I have a feeling it has to do with the stock case's small size, but I'm not sure.
The PC has 8GB of RAM, a Core 2 Quad, ~300 GB of space, and is running Vista.
(Here's the actual PC: [Newegg])

Any help would be greatly appreciated!!
 
What is the model number of power supply you have? Just because it says its a 500 watt unit, doesn't mean it puts out enough amps to power your card.
 
I'm not sure I would trust that power supply to run the gtx 460. Thats one of their lower end units. I would try a better power supply. Can you also post a link to the exact video card you have?
 
It shouldn't cause overheating but I agree that a new PSU is a good idea. I suggest you take apart the card (if it does not void your warranty) and replace the thermal paste, as well as clean the fans and heatsink of dust.
 
Could be bad case airflow, or just a high ambient temperature of the room the computer is in. Did you install the latest drivers or the ones on the CD?
 
If i was you i'd just get a new card,there not much money

but you can add another fan near your card or get a new case to cool your video card
