You would want a closed liquid looped cooler.http://www.decryptedtech.com/enthusiast-peripherals/cooler-master-seidon-120m-all-in-one-water-cooler-review/Page-4.html
- Cooler Master Seidon 120M is a very small cooler and won't block anything in your case, I assure you.
As you can see the Cooler Master Seidon takes on the Corsair H70, which ofc is better than the H60 and the Thermaltake water perform 2.0. The water performer 2 is more expensive and the Seidon 120M beats it. The H70 is a little ahead the Seidon 120M by 1-3 celsius, the price however is a way higher. http://www.newegg.com/Product/Product.aspx?Item=N82E16835103179
