So Corsair released (I don't know when exactly) some GPU brackets which are attached to the video card (Removing the stock cooler of course) and then an All-In-One CPU cooler is attached to this bracket; seems fairly easy to install, doesn't take much space (Depending on the computer case) and seems cheaper than installing a custom GPU liquid cooling system.

But is it worth to liquid cool a GPU like that? is it safe? (Considering a Corsair H100i exploded or something, and even some h100i GTX coolers had leakings, weird noises Etc.) I have the MSI GTX 970 4G, temps seem ok; even at 100% (Let's say 50°, 70°)

And finally, are these PCI express fans worth buying? or is there any other way to get a better air cooling system?
