Pros:

Cools well. Not too loud. Includes fan splitter.

Cons:

Installation was hard. Definitely requires at least 2 people, especially when securing the retaining plate. Radiator metal was slightly bent at some spots. Not a big deal at all, but I would expect a higher quality. Instructions for mounting the fans is lacking. Almost freaked out because I thought they didn't include fan screws. Thing is really big. 0 space between fan and RAM on my Corsair Carbide 300R. Trying to connect both fans to the CPU-FAN 1 and 2 is a joke. The fans do not need to be 4 pin but they are for some reason.

Other Thoughts:

The plastic cap for part that connects with the CPU is really good for spreading the thermal paste.

Manufacturer Response:

Hello,

My name is Robert. There are a few ways to install this hefty radiator and a second pair of hands, don't hurt. Any radiator it's important to be gentle as keeping the fins too thick reduces surface for air to pass through and push heat. We are working to keeping improving our instructions for customers. If you're having trouble, anyone is more than welcome to contact us by phone, 888-624-5099, or (Link Below) live chat where we can help instruct you on the process.

Yet, make sure for CPU_FAN 1, you have the block pump plugged in and working between the 1400-1600 RPM. The fans are 4-pin as PWM functions are becoming more and useful for motherboards that can support it. PWM fans help regulate temperature as the system needs vs 3-pin which runs only at full speed, unless regulated through BIOS or a fan controller. You, also, have the option of running the fans through the PSU at constant full speed if your motherboard does not have SYS_FAN and CPU_FAN 2 available.

Please contact us if you would like to learn more.

Respectfully,

Robert N.
