Hello everyone, I'm searching for a custom water cooling loop for the HAF 912 Plus. Do you think my parts will perform better than the Corsair H100i? I have a 120mm copper radiator and a 120mm fan. Check out these links:
- http://www.amazon.com/Yosoo%C2%AE-DC12V-...mp+cooling
- http://www.amazon.com/Universal-Computer...waterblock
I only need CPU cooling and not planning to cool the GPU. (It's just because I can't fit a large radiator in my case, so sealed water cooling isn't an option.) Thanks for all the suggestions!

Well, not really, but you're still only allowing yourself to have a 120mm radiator worth of cooling space? The problem is that 'just having a radiator' doesn't mean you have enough to cool what you need to cool. The reason that most 120mm closed loop coolers do not perform well is that they only have a 120mm (cheap aluminum) radiator and a poor pump. The pump you have listed will be better than a Corsair H100i pump, but you also have 50% the radiator size it does. If you didn't overclock your CPU, you would likely be fine, but if you plan to overclock, you are going to exceed the thermal capacity of the radiator unless you have higher speed fans (3000+ RPM) to compensate.
Plus, the 'HAF' series cases are designed to be 'High Air...

Well, not really, but you're still limiting yourself to just a 120mm radiator for cooling purposes? The issue lies in the fact that merely having a radiator isn't enough to meet your cooling needs. Most 120mm closed loop coolers underperform because they use a small 120mm radiator made of cheap aluminum and a weak pump. Even though the pump you have is better than some, it only handles half the radiator size. If you don’t overclock your CPU, you should be fine, but if you plan to do so, you’ll likely surpass the radiator’s thermal capacity unless you use high-speed fans (over 3000 RPM) to make up for it.

Additionally, the 'HAF' series cases are built for high airflow, which means they aren’t optimized for smaller radiators like 2x120 or 2x140.

My approach would be: if you’re running at stock CPU speeds, a suitable closed loop cooler should work, or you could opt for a better air cooler. However, if you’ve already overclocked and bought your parts, sticking with the single 120mm radiator and using fans in push/pull mode might be necessary.
