This water cooling (Corsair H80i) cools my processor (i5 4570) with no problems at 30 ° C and stays in the idle to about 28 ° C, while the computer is in the corner of the room. In the used housing in which reinpasst watercooling and works, there is a Prodigy Mini ITX by the company BitFenix. The water cooling suits with two fans a bit short in the case - if someone makes a Mini-ITX Build has planned. The fans were exchanged directly at the entrance of cooling with two Noiseblocker NB-Black Silent XL1 Rev.3. These fans run almost silently and hold the block cool. The H80i holds even after loading the CPU temperature in the green range. At my last water cooling (not from Corsair), the pump very annoying noise spreads, which are not present in this water cooling - you can exchange the product if the pump operates according to the operation.
