Corsair Hydro Series H100i GTX Extreme Performance Water / Liquid CPU Cooler. 240mm (CW-9060021-WW)

Pros: Like most Corsair water coolers this one is well put together and doesn't appear in the least cheap.

Cons: This requires a USB2 header on the motherboard to regulate the fan speeds or set the color of the LEDs. The cooler still works without it but you can make no changes to anything. Be aware that a lot of the newer boards are fully USB3 and don't have a USB2 header. My ASUS Maximus VIII Impact has no USB2. I can't even blame ASUS because I knew this before I ordered this cooler so no stars off for that but ASUS should realize they're shipping a new product that relies on old technology to work. How about an extension cable that could be run out the back of the case and plugged into an empty USB 3 port?
Can't say I'm a particular fan of the thick rubber hoses. They're too stiff and too big.

Overall Review: Can't really blame the USB2 problem on Corsair. I should have thought about it before I ordered this cooler and gotten something that didn't rely on a USB2 connection. Other then that a delightful cooler.

Pros: Worked ok for about 9 mo.

Cons: Title says it all! I tried for 1 hr to get in contact with Corsair; lines are busy. Newegg said to call Corsair. These types of products should ensure the cpu if it gets destroyed from product failure (like a power strip protection warranty). So now I probably have to wait forever for RMA authorization, and probably need to buy a new Skylake cpu (and who knows what else that got damaged from getting wet).

Overall Review: I bought this product because tomshardware.com gave it great reviews. I totally regret buying this.
