I need opinions on which water cooler I should get for my 4770k. A Tt Water 2.0 Extreme or a CM Seidon 240M? Or should I wait for Water 3.0 Extreme? If so, when is it coming to Canada? And will these fit in a Tt Chaser A31?

Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.
So by my estimation of this statement it would take almost a year of normal use to properly cure the AS5 compound, or almost nine days of continuous power cycles to meet their recommendation. Benchmark Reviews feels that this is a characteristically unreasonable requirement for any TIM product, and we do not support it. We want products that perform without the burden of sacrifice on our time, especially with some many competing products offering performance without this extra requirement.

Installing the Kühler is easier than most other compact liquid coolers due to the flexibility and length of its soft rubber hoses. The "universal" Intel backplate (on AMD systems, the stock motherboard backplate is used) keeps the parts count (and price) down, and while I prefer the more robust mounting system design of Asetek's original systems, the current mounting system certainly doesn't seem to affect the performance.
The performance of the Antec Kühler H20 620 was excellent, exceeding that of every other water cooler I've tested and encroaching on the performance range of the very best air coolers. The stock fan is quiet at full speed and very quiet at low speed. I tried replacing it with an 88CFM fan, which generated more perceived air flow and certainly more noise, but actually slightly less performance. It's not clear if just any 3-pin fan will work with Antec's unique fan speed control system, and it would be nice to see some information from Antec on this.
The construction quality of the Kühler was similar to that of other Asetek-sourced water coolers, which is to say that everything fit and worked correctly and the swivel mountings for the hoses pivoted freely. Antec silk-screens their logo on the pump housing and puts an "Antec" sticker on the fan's hub, but that's it as far as decoration goes. I'd like to see a little more effort expended on aesthetics.
But I'm not going to get hung up on the Kühler's minimalist aesthetic. The Antec Kühler H2O 620 is the best-performing water cooler I've tested, and that's why it gets a Golden Tachometer award.

The performance of the Antec Kühler H20 920 was excellent, exceeding that of every other cooler I've tested. .....The value part of the equation is where the Kühler H2O 920 comes up short, because as of February 2012 it costs $97.99 (Newegg). Despite its amazing performance, its high price means that the Antec 920 simply isn't a very good value relative to other, less expensive coolers that perform very nearly as well. But as I discussed above, "value" isn't necessarily a determining factor in this part of the market. If you want the very best, this is it... at least until the next great cooler comes along.
