HIS are using the same cooler on the HD 5830 Turbo as we've seen on the other two Turbo models from the company; it's done a good job in the past and should handle this lower end HD 5800 series card without any issues at all.
As you should know by now, the Turbo series is of course a pre-overclocked series. Here we can see that HIS have bumped the core up to 840MHz from the stock 400MHz clock. As for the 1GB of GDDR5 memory, that's gone from 1GHz to 1.1GHz or 4400MHz QDR. Compared to the stock HD 5830 we should see some nice little gains with the overclock on offer.
