Pros: Solid overclocking potential, multiple configurations, aftermarket fans improve value greatly
Cons: Stock fans are loud and have poor airflow
I bought my Corsair H80 back in April and have been quite happy with this product overall. The biggest drawback is that the stock fans from Corsair are something left to be desired, and if Corsair were to release a new design of the H80, it needs to have better fans, just like their cases need better fans. Corsair's fans are insanely loud and have poor airflow, however a couple of Scythe Slipstream 120mm fans and this thing is ready for some overclocking action. I wouldn't advise buying one unless it's on sale, that way you can get a pair of better fans right off the bat. I have pushed my i7 2600k to 4.6Ghz with the H80 before stress test, it will stay stable at 4.5Ghz under Prime95 no problem with the right fans. I like that you can choose to push pull your fans either direction, like most water cooling blocks. The biggest hindrances though have to be the thickness of the radiator and the flexibility of the hoses, if you have a smaller case you can't really place it anywhere other then at the rear exhaust port and the hoses don't bend nor are they long enough to mount it in another place in most cases.
