I heard they send a different version of the GPU for review.

May I know is it possible to buy the vrm heatsink and install them myself?

* I have no experience about installing vrm heat sink *

I'm not sure about the specific Sink on the review cards, but you can buy VRM/RAM sinks from any good computer store.

usually a pack with a bunch of different sizes and double sided thermal tape is only a few bucks. and it shouldn't be difficult to install.

Installation is relatively simple, remove the fan shroud and you have access to the chips, the heat issue with the Palit 2GB GTX 460s isn't only the lack of the VRM/RAM heat sinks, but the use of the Sonic edition - simple extruded aluminum heat sink, opposed to Sonic Platinum edition. To get a reference of what it looks like see below:

Aftermarket/Custom Modifications
Although Palit uses a non-referenced design PCB board, from what I understand you can use aftermarket coolers for G92/8800, such as the Scythe Musashi. Using a more efficient heat sink for the GPU effect temperatures far greater than installing heat sinks on the VRM/RAM, and according to Palit, they claim that the heat sink on the VRM/RAM/MOSFET isn't required during their tests - resulting in negligible benefits to mitigating heat or increasing stability with a factory over clock ( http://www.guru3d.com/news/palit-geforce-gtx-460-sonic-... )

Looked into the issue a little more deeply, and according to the testing performed at guru3D, comparing the use of heat sinks on the VRM/MOSFET, actually lead to a 5 C change, from 74 C to 79 C. But the results were for the Sonic Platinum edition, not sure how much it varies with the 2GB, whether the situation is better or worst, as the Sonic Platinum comes over clocked past ~800 MHz, whereas the 2GB version comes factory over clocked at ~700 MHz, but has additional VRM, in addition to the margin of error with TIM, air flow through the case, and other additional variables.

I think I'll just pick up a set of heat sinks too to try out.

While browsing some more, I also found an interesting IR scan/picture which confirms that adding some heat sinks there is warranted.

*However, it looks like the individual that used an IR camera, is cooling the GPU on water, so there is a lack of air flow which would diffuse over these components if using the stock air cooler.
