The other Thermalright heatsinks we tested recently were able to rank in a little higher in this list of reference heatsinks. The Thermalright SK6+ is showing its age, and coupled with a stock 60mm fan doesn't look like it has the necessary mix of thermal dynamics to do very well...

It would seem as the glory days of the Thermalright SK6+ are long gone. While the heatsink managed to dish out some decent thermals on the 100W small interface die test, it's really no match for performance cooling anymore.

What does this tell us then of pairing a stock 60mm fan with the SK6+? Well, while the Thermalright SK-7 managed to perform pretty well with a stock 80mm fan, the SK6+ just doesn't have the size to dissipate the heat fast enough.

The design of the SK6+ was good for its day, but now is really just relegated to the cooling that old Athlon in your file server. I'd hoped that the SK6+ would have been able to reinvent itself as a low noise heatsink with the right fan, but that's about all it has been able to manage... and at 50dBA there are far quieter options in the reference list to choose from.
