Cooltek W2 Review
With 163mm of room on tap the W2 is able to accept all but the very largest of tower CPU coolers on the market. As ussual for comparison reasons we've lobbed our faithful old Havik 120 in to the case for you to see what's what. As with all solid roof cases, there's no room to manoeuvre up top, so if your cooler has a complex mounting method then it's best you mate it to the Motherboard before you drop the lot into the case.
The W2 does though have quite good native water cooling credentials. For starters it's able to take 240mm radiators in the base. Obviously the thicker the rad you go for the less room you're going to have for PCI devices.
As you can see in the images below, even with our usual XSPC rad and 25mm thick fans we're already totally obscuring the last two PCI slots and impinging on the sixth. This won't be a problem if you're just going for a thick three bay single card set up but is going to cause you problems if you're looking to go multi card.
All is not lost though as the front of the case is also able to take a radiator. In fact with 75mm of room to play with behind the fans a decent thickness 280mm unit will fit just fine, remembering of course that you will be encroaching on the cable management holes and reducing the maximum GPU length. In the images below we've fitted an NZXT Kraken X61 280mm rad and as you can see there's tons of room left over.
