IntroductionI would like to thank Thermaltake for supplying me with the unit for review.
From the manufacturer Thermaltake:
- Application for video card with mounting holes on the PCB only
- Dual heatpipe moves the heat more efficiently
- Much better heat dissipation is delivered by larger heatsink surface
- Ventilation channel and blower fan improve the cooling performance
- Fan speed switch control the fan at different speed and noise level
- Universal clip for both nVIDIA and ATI
- Eight Copper Ramsinks included, can be applied on any chipset

InstallationInstallation of the Giant III is relatively complex because there are many parts. The instructions are very precise - split into three chapters keeping confusion at a minimum. The installation process takes about one hour if you do it the first time.
Here is a quick summary of it:
- Remove the stock cooler and clean GPU.
- Put thermal paste on GPU.
- Put front heatsink base on GPU.
- Put clipset on front heatsink base and fix it. I found this step a bit difficult to perform since the front heatsink easily moves around while tightening the screws. It helped a bit to just hold the screw with the screwdriver and tighten the backside screw with the other hand.
- Put rear heatsink base on video card backside.
- Put clipset on rear heatsink base and fix it. While screwing down the fixing screws I heard a strange 'pop' sound. After looking I found out that the screws go through the rear heatsink base, and push the protective adhesive tape on it away from the heatsink which makes a sound. This is perfectly fine and does not create any problems.
- Apply thermal grease where the heatpipes will contact the front heatsink base.
- Install front heatsink.
- Apply thermal grease where the heatpipes will contact the back heatsink base.
- Install back heatsink.
- Install fan on front heatsink.
- Install blower fan.
- Connect fans to speed switch.
On the backside the spacing between the Giant III backside cooling plate and Northbridge cooler is about 2 mm. Which is not enough if you plan on using a bigger aftermarket heatsink on your Northbridge.
