Summary: The temperatures for my particular chip are slightly higher than I am comfortable with. After a mild over clock to 4.4 Ghz, temperatures were hitting 85 Celsius in Prime95. Temperatures in games are 70+ degrees.
Pros: Powerful CPU that is more than adequate for gaming.
Summary: Running this cpu with the stock fan and paste, runs cools under minimal load. I ran a torture test (prime95) on it to burn it in, and the cores ranged from 77-80 degrees Celsius while under 100% load for a little over 2 hours. I'm definitely buying an aftermarket cooler so I can overclock it to above 4GHz when needed, but it does everything I need it to just fine with the stock settings and fan/paste.
Summary: Went from a Q6600 to this beast and it was night and day difference. The amount of processing power is just absolutely phenomenal. The 8 threads of execution just absolutely chew through everything you throw at them.
Pros: - OC'd to 4.5 GHz on a UD5H with a H100 cooler easily, - Very fast
Cons: - Very expensive, - Doesn't support some virtualization features that other processors do
Summary: This processor is an excellent overclocker and performs without generating as much heat as previous generations did (I'm thinking about LGA 1156). The aditional threads provided by HT technology grants you better performance in CPU dependent games and synthetic benchmarks over quad core i5's. In any case, considering the pricing, I would take one start from this product, since there are newer CPUs and this should produce a more important drop in pricing...
Solid at 3.5GHz. Able to overclock to 4.5GHz+ with some tenderness.

Summary: Great chip. If you're overclocking, you might look into 'de-lidding' it. There is an Integrated Heat Sink built onto it that has too much thermal paste and causes temps to rise more than the Sandy Bridge models. Fortunately, the IHS isn't soldered on like on the Sandy Bridges and a delicate hand can fix the problem. Research it first to see if you're up to the task. With a nice aftermarket cooler, you can easily get this thing up to 4.5GHz+.
