Assuming you don't want to overclock then that build will work as is, but I don't see a reason to buy a 2011 chipset if you're not going to use a 6-core processor (or unless you really want 64GB of RAM). Especially since you should be able to pick up a 3770K for the same price and then overclock it to be much faster than the 3820. In fact, benches show that the 3770K is just a touch better than the 3820 right out of the box - Source.

The TDP of the 3820 is also twice as high, so it's bound to run hotter than the 3770K (at stock), and it only comes with an extra 2MB of cache (not really a big deal). However, I will say that an overclocked 3770K is still bound to run a little warm (depending on the overclock), but since you're using an H100 you should have no issues.
