Summary: So much better than the noisy cooler that came with my AMD 8350. The fan is quiet and CPU stays around 32 deg C for average CPU load. My case didn't have room for 120mm fan so I had to do some sheet metal work to make it fit.
Summary: Put an AMD 8350 under full load with multitasking video converting, and running a few HD videos at once. Performance was flawless and core temps never exceeded 43 degrees C. Not bad cooling compared to 70+C with air cooling. Also the H55 runs quiet which is nice after the old fan thermal exchange sometimes sounded like a jet engine.
Summary: I've built and used many PCs over the years and never had a water cooler until now. I kick myself for not getting one sooner. My old stock fan was so loud, especially when gaming, that I needed headphones to hear it. With this Corsair, its so quiet and my temps on heavy gaming never exceed 27C. Definitely worth it and highly recommended.
Summary: I recently purchased 2 Corsair cooling units. They look like they could cool a car motor (Good Thing). I had a Vista Computer that ran very hot, since I installed 1 Corsair Cooler my Vista runs better than before I installed Corsair. It is large but I did get what I wanted. I think these should be standard on all computers.
Summary: It does a great job of cooling the CPU but I really would love to have some better control over it. The ability to change fan speed through some control panel or UI. But for the price I haven't seen any thing better. But the fact that I haven't had to modify a thing to get it to set it up makes it the best unit at this price!
Summary: Mounted the fan and heat exchanger first with no problems. When mounting to the CPU it can be difficult to determine the amount of torque necessary for a good interface. Four screws are used for attaching to the back plate of the CPU but they seemed difficult to screw in properly like there was to much paint on the threads. It's possible I stripped one but I left it alone because it was tight enough to do its job.
Summary: My system came with a defective CPU cooler and would hit 103C regularly. Far too hot. I ordered this H55 and installed it myself in about an hour. WOW! My Intel Quad Core i5 now hums along beautifully at 37C even under extreme loads. This Corsair H55 is worth it's weight in gold in saved productivity, and saved processor life.
