NZXT Kraken X40 Review

The Kraken X40 uses exactly the same mounting mechanism as the H110 which isn't quite as elegant a solution as that adopted by Corsair on the H100i, however, it is fairly straight forward when using the Intel Sandy Bridge-E platform which we will be documenting today.  If you want to see the cooler being mounted on Ivy Bridge, please see the Corsair H110 review here.

First of all, the retention ring must be prepared by fixing plastic mounts in each corner, so that the spacing is correct for the 2011 socket.  Then, the four thumbscrews can be inserted into place.

Next, the radiator and fans can be attached to the case.  Then, the ring must be affixed to the CPU block using the plastic bracket provided.

Then, the unit can be secured down into place, using the in built 2011 cooler mounts.  This does away with the need for a custom backplate.

Finally, all of the cables need attaching to your system.  The unit needs to be hooked up to the CPU fan header and the fan needs to be plugged into the fan controller in the CPU block.  The fan controller has an extra socket should you want to install fans in a push-pull configuration.

  4. Unfortunately the NZXT compat guide is totally false. The systems listed, majority of them are not actually compatible. For example, the Corsair Carbide 500R. The guide will state rear compatibility, which is entirely not the case. There is no functional way for rear placement. As for top placement, there is barely enough room, but it works just about. Impossible for any push/pull config however.

    When contacting NZXT about this, I was referred to Eric Henry the Tech Manager. He stated and I quote:
    “We have the same case, here and I have tested it on it before responding to your email”.

    I have had to make a video and take photos to prove he is lying and it doesnt fit. When called out on this, he said he must have made a mistake. Total and utter rubbish.

    My warning to people, go with something that you know is going to fit. Buy something that is made by your case manufactor or is 12cm in size for a more guaranteed rear placement setup, because if you base your purchase off of their guide, they will pretty much tell you to bugger off, cut your own case up, and bother someone else.

    As for product functionality itself, it works, so I guess thats a good part, just a shame I can’t return it for a refund and buy something that is compatible and has decent customer service.
