Having a look at the card, you can see that the cooler GIGABYTE has opted for isn't anything we haven't seen before. With that said, it's one we've been happy with a few times now due to the fact it's an 80mm fan which means it's able to push more air at a lower RPM, which in turn means less noise.
Apart from the GIGABYTE sticker in the middle of the fan, there's not a whole lot more to look at thanks to the fan itself having quite a large shroud around the 80mm fan that manages to cover up most the card.
Like other HD 5670s we've looked at, the card lacks the need for any extra power connector, but does carry with it the standard CrossFire ports that we're use to seeing on the HD 5600 series and above.
In the I/O department we can see that GIGABYTE has dropped the DisplayPort for a VGA one. They have still included HDMI and Dual-Link DVI, though. While the card uses only a single slot for the connection, it is a dual slot card due to the larger nature of the fan.
When it comes to having a look at the clocks of the GIGABYTE HD 5670 OC, we think that the OC title might have been a bit of a stretch. Looking at the 1GB of GDDR5 memory, we can see that GIGABYTE has opted for the stock 4GHz QDR clock.
On the core front they've bumped it to 785MHz which is only 10MHz above the stock clock of 775MHz. With that said, this isn't the first time we've seen a company offer only a small overclock and slap the OC tag on the model.
