Bios update for palit GTX460 Sonic Platinum MOSFET heatsink Problem

In a phone conversation with Palit on Friday Guru3d guys have requested some sort of statement for the end-users, this arrived this morning:

To who it may concern,

That review sample is the very first model we made, after finalizing the BIOS, there was no need to add a VRM heatsink.

GTX 460 1GB "Sonic Platinum" without a MOSFET heatsink (the samples for review had the heat sink)

1. It is no need to add a heat sink for those components (MOSFET power circuit).
We had passed the thermal qualification testing for the the specification. The NV reference board does also not add it too.
2. 100% burning tests for the GTX460 1GB "Sonic Platinum" (We have tested and done burning test for each "Sonic Platinum" board before shipped out to our customers. The "Burning test" - with at least 2 hours under 45 Degree C inside the chamber
3. The temperature on the GPU, memory chips and VRM components of the GTX460 1GB "Sonic Platinum" is not over NV specification under 45 Degree chamber. (We run 3Dmark2006 "GT2" that was suggested by NV for the Thermal testing.

Please be confident with our serious testing process, which you do not need to be worries about an damage possibilities.

Quality is always out priority. Thank you.
