One thing bothered at one time and from the very beginning and the other increasingly:
1. Installation is a disaster. Do I have the fan on the heatsink, I get the fixings on the board barely attached. If I take the fan before installing from going though - somewhat - but I can hardly attach the heatsink. Next two RAM slots at my Asrock board are covered, low profile RAM but still it fits. Since there is always a middle ground between the radiator height and space for the surrounding components must be found, I will not complain, but memory with high heatsinks I could install only on the two outer seats.
-Allerdings - But it can of cooler nothing - I do wonder: it is well known that the cooler is greater. Why is the board vendors not possible to take this into account and continue to put the memory banks a little to the edge? As I said, for this problem, the cooler nothing, it has no effect on the rating.
But for fumbling when fixing it can be quite a bit. In the year in which I have him now, I only have to expand it again - to just get to the RAM chips and had to cancel almost my fingers again. A miracle and a sign of the good quality of today's components that the motherboard and the CPU have survived the ordeal. Why must it take nearly an hour to secure a CPU cooler? The box cooler sat quickly and easily.
Fortunately do you do that not so often.
2. But what is making very negative effect for just over a year, is the fan, which is increasingly louder. I'm not an expert, but the restless clacking seems to indicate to me on a camp out proposed, especially as the air flow noise are themselves clearly audible. I have no comparison, I have only BeQuiet Silent Wings 2 installed, moreover, show in any case to me that there is another way. Primarily because of the potential bearing damage worries me, I just ordered 92mm Silent Wings and hope that I get somehow fumbled on the radiator, because the two metal clips that will keep the radiator, a real punishment for the makers are. Something is but hopefully come to mind.
In short: The cooling capacity on the i5-2500K is good, so it seems to me as such to do his job dutifully the heatsink. The fan is now a year old and "by" while the BeQuiet-case fans do for almost three years their work without hesitation.
The two points I do not draw from the fans - what do you expect? A Silent Wing will cost almost as much as the entire fan - but only for the poor design of the attachment.
