Yes, I found that this unit tested well on the Intel Extreme Burn In. I ran all 6 cores at 100% with an overclock of 3.55MHz. At the same time FurMark was running at 1920x1080 x4. The temperature with an Intel Extreme Air Cooler never exceeded 65C during an eight hour test.

Built a new (using an older x58 motherboard) system with this Core I7 990X. This is the fastest processor for this motherboard. I coupled this great processor with the Extreme cooling fan from intel. Frame rates in games, intensive video along with various media applications are so much improved with this intel 32 nm technology. What is old is new again!
