I baught a pair of r Visontek 6850's from eBay for pretty cheap. They were brand new, but I knew that Visontek would not honor a warranty from there. Well, one of the fan have already died on me, and I need a replacement. I can't find a fan that will just swap out with the stock one. I was looking at the Zalman VF1000 and I was wondering if anyone else would like to chim in on some suggestions. My case is a 700D so Airflow is not that great, but I do have an existing loop for my CPU. I have a 360 Swiftech Quitepower Rad on the top with some high-pressure fans and shims. Since some universal waterblocks would fit, I'm just wondering what the best option would be....
