I purchased a water x-cpu water cooler from 1COOLPC and installed on my amd 2100 athlon. I sometimes have a high room temperature that my computer has to operate in so I wanted some enhanced cooling and the water x looked like it might be a good answer. The water x appears to have been designed very professionally and looks to be built very well compared to other coolers I have tested. At this time I have only limited experience with the water x unit but it runs very quiet and holds temp very well. After only a week and one half of use my water-x had a major malfunction and had to be replaced. A-Pros Eddie Lin and 1COOLPCs Bart Lane came to my rescue in the toughest of situations standing behind the water-x cooler 200%. I was very impressed by the support service for the water-x cooler. In my opinion water-x, A-PRO, and 1COOLPC deserve awards for their customer service. I would not hesitate to recommend the water-x cooler or 1COOLPC or A-Pro. I am sure the replacement water-x unit will be just fine and I know their reps are very reliable and honest.
