Summary: I've been using this product by Intel with Intel Core i7-3930K Hexa-Core Processor 3.2 Ghz 12 MB Cache LGA 2011 - BX80619I73930K processors and so far had no problems with them, even where there's no air conditioner installed the temperature stays at 40-45 degrees celsius. Silent operation and well built.
Summary: This cooler worked just fine for a LGA2011 processor. Like other reviews the chip is bigger than the contact on the cooler. The plastic piece that protects the thermal compound came loose in shipping and some of the compound smeared which I believe is bad packaging on Intel's part. The fan makes little noise and the heatsink seems to do a decent job at cooling the chip. Pros Cheap Not noisy Easy to install Cools decently Nice little blue light when the computer is on.
Summary: Fit perfectly on an Intel LNA2011 processor on EVGA SLi motherboard. This will be much more reliable than the Corsair Hydro which failed. Solved my problem with CPU temperature shutdown. Easy four screw installation and a plug. The fan unit runs quiet and glows blue.
Summary: Gives excellent cooling, with much easy installation. One note though about poor documentation, the supplied manual says it needs a backplate to be fixed on the motherboard prior to installation, while actually it doesn't need any plate.
Summary: This fan/heatsink assembly arrived with the thermal paste smeared and ruined. The circular clear plastic top that is supposed to protect the thermal paste was dislodged and smeared/lifted the thermal paste. A proper packaging design would have prevented this.
Summary: I've heard talk around the internet about the stock intel cooler being sub par; now I can understand this could be an issue if you didn't adjust the fan speeds, although I don't much care about case noise so I cranked the fan to 100% and it keeps my temps around 32c at idle and it only reaches 43c under load clocked at 4ghz, I'm impressed.
Summary: Nothing fancy here, pretty much what you would expect for a stock cooling solution from Intel. The base of this heatsink is very small, I don't think it even covers the entire processor. There is also a very minimal amount of copper on the base. On the positive side it provides adequate cooling, just don't plan on overclocking. It's also very quiet which is always a good thing. Overall it's a decent heatsink for basic cooling, plus the price is cheap!
Summary: I don't have air conditioning in the summer, and I don't like the idea of water cooling, so I was concerned that I may be building a noisy air-cooled monster. I was resigned to live with a bit of noise, since I had another dead silent system which would be powered up most of the time. I figured that I would order the Intel stock air cooled thermal solution, BXRTSLGA2011AC, until I could find something better suited to my needs.
