Summary: Use this to replace an H50 model. Put opn I7 860 in a NZXT Phantom 820 case. Installed on top Inside the case. Put 2 Noctua NF-A14 PNW on top in beetween cover and case as iontake in push config. Put the 2 corsair fan as intake Inside the case as pull fans. Used with Gelid Extreme thermal paste Temp stay between 24 and 43 C.
Summary: This is a fantastic CPU cooler. I bought it for a budget build I did and it works great. I would have liked to see some sort of fan hub/splitter included though as I only had 3 fan headers on my motherboard and it used all of them.
Summary: This is my first liquid cooler. I put it on my i7-4930k 6-core processor. I have had it rendering full bore (All cores running 100%) for 3 days now locked at 3.90 Ghz. All CPU's are holding temps between 51-57C. What is strange is that when the system sits idle the core temperatures actually rise because the pump is not circulating as fast.
Summary: Purchased two of these from different retailersUnits are easy to install. BE WARNED - this unit may not fit your case, make sure you check all measurements before ordering. The only downside to these units are the cheap and nasty fans that Corsair supply. Shame on your Corsair. Both my units have noisy fans and I see this is a very common problem for these units. Corsair customer service is a complete joke.
Summary: I attached this to a i7 4770k and my old stock fan would over heat with any overclocking. This thing allowed me to overclock to 4.5Ghz stable. My temps are 85C max load, and 25C low work load and idle.
