The cooler isn't fundamentally different from those used with the previous GTX solutions. A turbine drives air through a heatsink and ejects it out of enclosure. However, due to the extreme power consumption of GeForce GTX 480, the cooling system has been improved in the heatsink department. As you can see, the heatpipes only cool the core, while memory chips are taken care of by a plate under the cover.

They have probably run out of ideas on how to make a silent cooler powerful enough to deal with such a hot core. So have in mind that the cooler is very noisy. Even in the 2D mode, it works at 44%. Compare this to the 20-25% of the previous graphics cards. The noise, however, starts after 50%. So the idle mode feels like you're about to hear the noise. And you do -- in the 3D mode, when the cooler speeds up to 70-80% on average.

Traditionally, we monitored temperatures using RivaTuner.

The core heats up to 95°C, so you might as well forget about quiet, even if you only want to watch a movie or something.


A basic bundle for such graphics cards should include the following items: a user manual and a software CD. Now let's see what other accessories are bundled with each card.

A basic bundle expanded with power adapters and a mini-HDMI-to-HDMI cable. Plus a bonus disc with demos and other free stuff.

This is also a basic bundle plus power adapters, a DVI-to-VGA adapter and a mini-HDMI-to-HDMI cable. Note that the 8-pin power adapter requires connecting two 6-pin PSU power cables. Therefore the bundle includes corresponding molex-to-6-pin adapters.

A traditional glossy jacket enveloping a thick cardboard box. The card is securely stowed into a polyurethane foam compartment to avoid transportation issues.

The Big Eye is watching you! It wants you to buy a new card at once!

A stylish box without a jacket. The card is also securely fixed inside.

The car probably symbolizes your PC, while the monster symbolizes overheating. Make sure you provide sufficient airflow or your machine's done for!
