Hello friends, I do not know that how many have got this problem, but I am getting it. To start computer you have to remove EK water-block or EK's "workaround" which is been used inside your computer. I think that this is very much know problem with EK-MB water-block, if anyone is thinking to use then let me tell you that it will be creating short circuits on Asus Crosshair V motherboards. I believe that it is happening due to copper base shorting the SMD elements surrounding the northbridge chip. I have seen this problem now and earlier I was not at all aware of it and also there is no instruction about it. When this problem has occurred then I have done checking of the system but there was nothing which can make it proper. So just order new board for my system and also like to tell that when I was visiting EKWB’s official site to get a new heat tape by which I can mount it on new board then also I was able to found this problem listed over there, even there was solution to solve that just use scotch tape over the SMD elements. But one more thing which I have found shocking was that, specification for it was been changed. When looking on those specifications I will be not using scotch tape and totally wasted my money for it. Removed water-block, there were plenty of tiny burns in the copper from electrical arcing, once it was removed then computer start working. I was very much surprised that EKWB is not ready to agree that there was problem in their product. I do think that there is any clue such that under the clamping pressure and thermal stress that this will be a long term solution. Now have to order a new water-block for computer. Just wanted to share this thing with you all so that no one get problem with water-block. Thank you.
