Your Palit GeForce GTX 460 Sonic could have issues
The reviews on the Palit GeForce GTX 460 Sonic Platinum edition have been extremely positive in most reviews, including ours in the GTX 460 shootout. Great performance, good cooling and an extremely silent noise level. However earlier on Wednesday we noticed some reports in our forums that an batch of the Palit GeForce GTX 460 seems to be missing the VRM heatsink.
As a result the cards temperature could heat up massively and the cooling will try to compensate by spinning way harder (RPM) and this it makes the product loud. Is yuor VRM/MOSFET area exposed like that ? Here's how you can identify this:
To the left a photo of our review sample, clearly visible is the black heatsink located to the back of the PCB. To your right you can see the same product, yet missing is obviously that heatsink.
If you purchased a Palit GeForce GTX 460 Sonic Platinum edition graphics card, please check if that black heatsink is missing.
So apparantly it is common for Palit to submit better samples to the press opposed to what they sell in the stores: Here's an answer from Palit which makes clear as to this apparantly was done on purpose:
