I have an Intel i5 2500K, ASRock Z68 Pro3, 8GB Corsair bought me last week XMS3 memory and this cooler. The first thing I thought when unpacking the cooler fits the old Swede ever in my body clean ?. After about 10 min. Fiddle until I have the radiator bolted together properly (with one of the screws that the thread is no longer good, but how heißts so beautiful what is not fit made to fit), I was able to install the cooler Kinderleicht. Sorry, no backplate is included, which means that one of the cooler "only" with the standard Plastikklips may fix as the original cooler, to my surprise, he sits very stable on the CPU. The processing of the radiator corresponds to the price a little sharp-edged the Good, I got injured when mounting the 8 pin connector on the hand, regardless of plaster on it and then kanns continue. After everything was connected, I have started the PC and hear nothing. The cooler is so quiet that I thought he would not run. I have found in EFI or BIOS the radiator on minimum speed and lo and behold the CPU is not even warmer than 45 ° C with CPU-intensive applications such as Crysis 2, Battlefield BC2 or Photoshop. When max. RPM setting in the BIOS it goes even rarely over 34 ° C (measured with Hardware Monitor Sensor and EverRest Ultimate), so overclocking the DERS should therefore need to be in there too. So who wants to have a little money and lots of power with a little worse processing can be accessed safely here. 4 stars because I got myself an injury during installation. A little tip in the end you have your housing measure whether the cooler fits in with an acquaintance of mine, you can not close the case. Delivery and shipping was great as always thank the Amazon there is you! I test a lot of fun times continued to buy.
