Aftermarket Fans and CPU Cooling

Hello,
I ordered the Aurora R12 yesterday. I purchased one of the Black Friday specials. The price was great, but the upgrade options were not. With this said, I've discovered that the stock fans and CPU cooling are pretty undesirable. I've seen people post aftermarket fans and say that eventually the computer wouldn't boot up properly due to the aftermarket adjustment. I called tech support today to try and buy the Alienware CPU liquid cooling kit. The support staff were very kind, but could not seem to understand my request no matter how I worded it. Can you guys point me in the direction for some fans and a liquid cooling kit that will work will this PC? I greatly appreciate your time!
