Q: Would this fit into the front of the NZXT H400 Mid Tower case?
Answer by Website User on 5th September 2018
The radiator will fit but the cable to the pump may not be long enough. I would recommend installing this into the top of the case.

Great cooler. Keeping Intel i7 5960X below 40"C under full load. Very quiet, worth the price.


last month

Low price. Difficult to install, only 2 screws to the existing mounting bracket for AMD. Keeps the CPU nice and cool at around 28 degrees idle at 100% pump speed and 30% fan speed. Adjusting the fan speed any higher makes it sound like a helicopter attempting to take off. Makes me wish I had stuck with air cooling. Not sure what all this silent fan advertising was about on the coolermaster website for this product, complete nonsense. I intend swap the RGB fans for a set of NZXT standard case fans which run faster and are much quieter. Would not recommend this product unless you are Intel and intend to swap the fans, in which case why bother with the RGB version really.

Very easy to fit, looks great and does the job perfectly while still costing half of the equivalent Corsair product. All games with average overclocking my Ryzen2 2700X does not go above 45deg C. Recommended product.

A fairly simple assembly job initially comes with all mountings & thermal paste easilly mounted in roof or vertically on case front . Basic RGB controller but looks good when running. Thermal performance very good CPU averaging 32c good value all round
