If the fan is bugging you that much I would save up for water loop. Even if you keep the RIVE 3way 670s you are going to run into some CPU bottleneck that will require some high CPU OC. Water will help you achieve a the higher OC needed while keeping temps low to protecting your investment. I have only seen a PCH heat sink combo with VRM water block for the RIVE. http://www.performance-pcs.com/catalog/index.php?main_page=product_info&products_id=33426
it frankly does, cuz am running a quite system with noctua and seasonic 1000w platinum psu, and a punch of NZXT fans and the system is relatively quite, and I have the case sitting on top of the desk, so when this little fan is plugged it becomes really annoying, speaking of waterloop I frankly was thinking about it yesterday
and said to my self instead of spending money on a new motherboard I could just go waterloop, but am kinda terrified that something may go wrong and a leak happen or such, where there is no way I can send any of my hardware back for repair or replacement. I know very little about water cooling, apart of owning a corsair h100 4 months ago, I know how it works but I don`t know how to put it together it and install in on my pc , I will probably start reading about it and thanks for the link you sent me, these blocks look cool, but am sure there are plenty of other blocks for the rive, that require some research. are you watercooling, if so, how easy to install and how safe it is?, does it require much maintenance, like draining the water few months or so?
