Comments: I got this item less than a month ago. It generally was easy to install and performed well but due to its plastic enclosure, it all of a sudden cracked and what happened then is horrifying. Though, I probably lucked out at most of the liquid just sipped onto the bottom of the case but some of it got around and into my agp slot frying my x850xt, and it then went down a few more slots and even though it leaked over my secondary NIC and Audigy2, it didn't fry them. My whole northbridge was wet but luckily it survived and I managed to clean up the leak from inside the agp slot and get my computer back up. And I didn't even get to OC my rig after I got this waterblock...I dare not thing what would have happened if I did. If you need a NB waterblock, please look further and make sure to get a solid sealed copper or aluminum one instead, avoid any blocks that have plastic window on them. Now I have $500 worth of stuff to replace because of a $20 waterblock, amazing! CoolerMaster products are generally good, but don't get any of their waterblocks that have windows or plastic. Same probably goes for waterblocks made by other manufacturers that fit within my above description. AVOID THIS ITEM!!!

Pros: None

Cons: None

Overall Review: Liquid is conductive. Water that is not deionized is conductive. If you think otherwise, climb into a tub of water and toss in a running hair dryer. Even deionized water will become conductive over time by taking ions from your waterblocks. This effect is accellerated in areas of high heat. As far as the cracked block is concerned, your system should not be able to create enough heat to cause a crack under normal circumstances. I would guess that the crack was pre-existing, maybe caused during shipping, and was only spread by the heat of your system. Unfortunately, since you were using a conductive liquid, the manufacturer will most likely not cover damages from a faulty unit that could have been avoided by using a quality coolant.

Pros: Low Price.

Cons: Ran in my system for about 3 weeks and then TROUBLE. Hair line crack in the block . Leaked on my mother board,vid card & sound card. Long story short.My ASUS P5GDC-Delux mother board is dead also my audigy 2ZS sound card is dead. My BFG 7800 GT OC survived :).

Overall Review: The clips to mount the block are a pain to use.
