PRODUCT PICTORIAL AND WALKTHROUGH
Twenty-five aluminum fins help dump heat from the heatpipes and the fins themselves have a number of through holes stamped into them to aid air movement through the array for efficient passive cooling.
The bottom of the cooler features a thermal pad protected by a plastic sheet and the mounting plate has numerous holes to accommodate supported graphics cards. The thickness of the thermal pad is necessary to make up for surface irregularities and electrical contact points. The use of thin, conductive thermal compounds here would clearly be a bad idea.
As you can see, the ‘pipes are flattened somewhat and a channel cap is soldered over them for maximum heat transfer. The whole works is then nickel-plated for an eye-catching and corrosion-resistant finish.
PRODUCT INSTALLATION AND TESTING
The user has a couple of orientation choices when installing the HR-11, and both can be used when running cards in SLI/CrossFire applications. For this review, I'll be using the rear-facing option (as illustrated in the topmost card in the photo above) to take advantage of the airflow provided by the rear exhaust fan in my Zalman Z-Machine GT1000 case.
I'll be putting the HR-11 on my EVGA 8800 GTS graphics card. Thermalright has included an instruction sheet, but installation is so easy that, while helpful, a user's manual is almost unnecessary.
One simply needs to remove the OEM fasteners, choose the correct screws and tighten them into the mounting holes of the OEM cooler. Installation can be accomplished in well under ten minutes with a small phillips screwdriver being the only necessary tool. Don't forget to remove the plastic sheet on the thermal pad! You won't get much cooling performance out of the HR-11 if you do.
