I replaced the case fans with Noctua IPPC NF-F12 case fans, radiator fan with a IPPC NF-F12 and NF-A12x15 for push/pull.  Use Throttlestop or Intel Extreme Tuning Utility and work on the voltage off-set.  Mine was best at -0.105mV. Here's a breakdown of how mine was.

I bought an Alienware Aurora R13 a few months ago and it came with the regular water cooled cooler. I would love to upgrade to the Cryo-tech solution as it would hopefully help keep my system a little more quiet and cool. I tried calling Dell and they said they're only offering storage and ram upgrades. If you can direct me to a place where I can purchase such an upgrade of if someone here changed their cooler and would like to sell the cryo-tech one and ship it to me for a fair price (I live in Israel) you'll make my day. Thanks in advance.
