The Zalman LQ320, which the other poster recommended, for $39 from newegg is probably the best deal on a closed loop liquid cooled CPU cooler right now. It is comparable to the Corsair H60 in both design and performance. Newegg also has a rebate on the old H60 (there is a new H60i) for $55:

The best closed loop system is the H100. It is the best performing, but at $130, it isn't the best bang for your buck and doesn't lead the 120mm single fan closed loop coolers by much. Check this list out. Use the 85w readings for reference. It is closest to the 77w TDP of an Ivy Bridge i7:

If you go to page one of that article, it is a detailed review of the H100. Frostytech is a very good resource for information on CPU coolers in general. They measure the performance on both Intel and AMD boards and also the decibel levels of the system. Each CPU cooler is measured both with the fan or fans on high and low and they post both results. The temp readings are how much the CPU's temp is above ambient temp in Celsius.
If you are on a budget, the Zalman LQ320 is sufficient for mild overclocking of a i7 3770k. At $100 less than an H100i, it is 1/4th of the price but only about 15% less in performance. You should be able to clock it to 4.5 GHz, maybe even up to 5.0 GHz. The H100 might be able to do 5.0 GHz as well, but at slightly lower temps. I can't say for certain since all CPUs are different even if they are the same model. One person's 3770k might be able to hit 5.0 GHz while another's 3770k might only be able to do 4.2 GHz stable. I have an air cooled (Hyper 212 Evo) 3770k and it is running at 4.5 GHz with just a multiplier increase. I am using Speedstep and Windows Processor power management to downclock it to 1.9 GHz. I highly recommend Speedstep even if you aren't overclocking. It will use less power and keep your system cooler while extending its life as well. And the best part is you won't notice it when the clock speed fluctuates. It happens seamlessly.
