I chose this model for its dimensions that stick in my Silverstone SG06 case. I get at least 20 degrees cooler compared with the original cooler on my i5 670. FYI I have a Gigabyte H55-USB3.
Very satisfied, more this price is given.
Reflective in there if I had the space in my case, pay 20-40 euros more to lose 2 to 5 additional degrees would have been a ridiculous idea.
