“Sandy Bridge-E” (LGA2011) Core i7 3820, 3930K and 3960X CPUs may be sold without a heatsink and fan in the box, which is unlike Intel. Instead, Intel will market certified CPU coolers independently in a market that LGA2011 aftermarket cooling is already available.
The end user is suggested to utilize liquid cooling with these three processors. TDP is 130W rated, with reports of closer to 180W used. Intel told power supply makers to make sure that their PSUs can handle a peak current of 23A on the 12V2 rail and accomplish this with an 80-percent or higher efficiency rating.
The Core i7 3960X Extreme Edition is a $999 USD enthusiast grade CPU, with 6 Cores/ 12 Threads, 15 MB of L3 Cache, and operates at 3.33 GHz (3.9 GHz turbo) . The Core i7 3930K received a price in the middle at $583 and the Core i7 3820 will be priced at $294.
At least four more Sandy Bridge-E processors are to arrive by mid year of 2012. The Core i7 3980X Extreme Edition CPU (possibly Intel’s flagship Sandy Bridge), the Core i7 2800K to retire the i7 2600K, and two more replacing the 3930K and 3820 processors. Like the rest of the upcoming chips, they may ship without heatsinks and fans in the box.
