SilverStone IceMyst 420 AIO Watercooling Review

Installing the SilverStone iceMyst 420 is extremely easy.  This cooler doesn’t have a universal mounting system but, come with hardware enough for current platforms on the market.

We will be testing on the LGA1700 Alder Lake platform with a Core i7 12700k processor.  There are different blackplates for the LGA1200 and LGA1700 so be sure to grab the correct one for your system.

With the backplate installed you’ll need to use the correct mounting screws to hold it in place.  These screws are marked on the plastic bag and control the deck height between the CPU and pump block.

Thermal compound is an important step.  There are a number of different methods for installing compound and while I prefer the superior 5-dot method for repeatable thermal results it has been proven that running your system without thermal compound is worse than trying to replicate the methods used by your favorite tecutainmentTuber.

To install the pumpblock you will need to attach the mounting rails.  These slide into a groove on the pump block and align with two locator notches.  The notches are located opposite the hoses and should lock in place when installed correclty.

To install the cooler, simply align the holes in the mounting rails with the screw posts and lock it down using the included spring nuts.  You will want to install them in a progressive cross pattern to ensure even pressure.  This ensures that the thermal compound makes great contact and is easier to get the screws tightened.

The iceMyst fans are special in that they use a socket connection for fan and RGB control.  Each wire pack is just long enough to daisy chain the fans without any excess wire.  This helps with the cable management and when positioned correctly becomes almost invisible.

Personally, I assembled the fan tails before installing them on the 420mm radiator.  The dual mounting holes made it somewhat difficult to get the screws to line up but, things worked out eventually.

The IMF70 ARGB fan modules are easily installed across the top of the pump block and allow you to reposition the fans to where extra airflow is needed. 

I do like how the AIO radiator fans spin independent of the IMF70 fans and pump block motor with each having a separate fan input.  Of course, you can link all of these together or, you can dial the speeds in differently to better control the level of cooling you need.
