Input: Bought 2 of these from another reliable vendor.<br />The first cooler failed after about 3 months, it was RMA'd back to Corsair.  Prior to sending it back it was examined, there apeared to be corrosion around the copper waterblock (which is not really a water block, more on this in a minute).  The second cooler failed in exactly the same way.  Again more corrosion.  This time, thouroghly fed up with Corsairs terrible support I dismantled the entire cooler.  I found extensive corrosion to the back of the copper &#34;water block&#34; I pulled appart the stupidly designed pump to find more corrosion to the internal surface of the impeller around the spindle.  The was the cause of the rattle that is the sound of failure, the only way to repair this cooler is by replacing the pump unit as the spindle is damaged by the corroding impeller too.  The cause of failure.... cheap coolant that was acidic.  Certainly was not coolant that was designed for this kind of use.  The seal around the &#34;water blocks&#34; copper contact surface is very bad too, this allowed for a small quantity of coolant to make its way out and air to make its way in, further compounding the failure.<br />The way the thermal sensor makes contact with the copper is very poor, leading to inaccurate thermal readings and control.<br />The &#34;water block&#34; is laughable, its a thin 2mm peice of copper plate, on its back is a rubber material obviously desinged to flow control the coolant.  This rubber covers most of the copper and so prevents thermal transfer heat from the copper to the coolant.  The corrosion mentioned earlier obviously corrodes the exposed area of copper and so furhter reduces the performance of the system.<br /><br />Its a pooly designed, badly made peice of garbage.  The designers of which have/had no clue on materials science or even rudimentary chemistry to understand how their materials would be affected by the coolant they choose.  I can't speak for their newer models, but needless to say I have completly lost faith in Corsair products.  Had a few cases and had problems ranging from catches breaking, fan control knob failing and even broken front usb port cables.  Memory I have had a few and the heat spreaders became loose on all of them, one shorted out.  Dont get me started on their SSD's  Thats for another review.<br /><br />Their replies to all of these complaints:<br />&#34;You can return the item, once its received and the fault is validated we will send you a replacement free of charge.&#34;<br />I said:<br />&#34;So I have to have my system out of action for 2 weeks becuase of your terrible product&#34;<br />Their reply:<br />&#34;You can avail of our swift replacement option, you provide us your credit card details and we send a replacement, your card will not be charged if we receive the product back&#34;<br />Thats all well and good I suppose, but every time I tried to arrange to have my product replaced in this was I was told &#34;That Item is not in stock&#34;

Worst cooler on the planet even worse support from Corsair
