Stephen C wrote: No problem with the product overall, but be aware that the installation is far from simple - once its in your machine though it works like a dream!

 Product pros
the fans are so so quiet and my temperatures have remained below 70 at all times with an 8700k and a gtx 1080.

 Product cons
the build was a nightmare - the fan brackets hurt your hands a lot and you'll need low-profile ram sticks (such as corsair's vengeance sticks) to fit under the cooler
