Review on AMD Athlon II X3 400E Energy Efficient Rana 2.2 GHz 3x512 KB L2 Cache Socket AM3 45W Triple-Core Processor for Retail - AD400EHDGIBOX by Nguyn Thng Qun  (Chu ᠌

The already quite high-performance Athlon II X3 460 processor turns into Phenom X4 B60 by unlocking the fourth core. The Windows performance index in the unlocked and non-overclocked version was 7.4, so I see no point in overclocking it further. With a simple cooler with a copper core, the idle temperature was 27-28 degrees, under the maximum long-term load on all 4 cores it did not rise above 54-55 degrees. I took a new one for 40 American - an excellent combination of price and performance! I definitely recommend it to owners of boards on AM2 / AM3 sockets with a TDP of no more than 95 watts.
