Yep with 1700 I have similar results. Thanks to my toyota hilux radiator, which i bought on ebay in 2006 for 20 Euro. My water cooling was amazingly cheap and is amazingly efficient. The components last much longer than usual due to the lower temperature. My enermax infinity 720W power supply has actually been in use for 11 years, because it also benefits from the cooling.
