I just did a review on a Thermalright SK-7 and this is the little brother to that heatsink, the Sk-6+. This heatsink is almost identical to the SK-7 and has a lot in common with the SLK-800. The only real difference between the SK-7 and this heatsink is the fact that this heatsink can only hold a 60mm fan while the SK-7 can hold a 60mm and 70mm fan. This heatsink is about $8 cheaper than the SK-7 which is one reason you might want to go with the SK-6+ over the SK-7. If you are only looking to use a 60mm fan and want to save some money this SK-6+ would probably be a better buy for you.
