A closer look at the Gigabyte Radeon HD 5670
The Gigabyte Radeon HD 5670 is a little longer than 6 1/2 inches and has a fan that almost covers the entire PCB! The reference card only takes up one PCI-e slot, but with the size of the fan in this Gigabyte card, you will be using two slots. Looking at the Gigabyte Radeon HD 5670 card, you can see that there is no external power connector needed. That is nice for those that have an older power supply that does not have this type of connector on it.
The back of the card lacks any type of heatsink for cooling the memory IC’s. Even in our overclocking, there was no real amount of heat produced that would have required it. The Gigabyte Radeon HD 5670 features 1GB of GDDR5 memory, so there are four IC’s on the front and four on the back.
The Gigabyte Radeon HD 5670 1GB GDDR5 graphics card that we looked at
used eight Samsung branded memory IC’s with a part number of K4G10325FE-HC05.
This Gigabyte card has Dual-link DVI-I, VGA and HDMI outputs, and is capable of multi-view technology.
As mentioned, the fan is extremely big on this Gigabyte video card. In fact, it is an “80mm Large Fan” as Gigabyte so proudly displays on the box. It is very quiet though, as I hardly ever really noticed it during any of our testing. The heatsink itself is also very large, and obviously does a fine job of cooling the card during use.
