Yeah any of the Core Duos could have the whine issue, although it was the particularly the early models which were worst affected. Heat is not so much of a problem with the latest firmware updates and a copy of smcFanControl, but the C2Ds are still better.
Since an Apple refurb 2.16 C2D is just £200 more in the UK, might be worth the extra. None of those issues plus more HD and RAM.
