Good performance poor fan

Have the radiator now for 1.5 years in operation. The performance is ok, even if there are more, for example by Noctua. What has me very disappointed is that the fan broke down after about 15 months, which was a bit early yet. Even if a new fan is not much it cost, it was a little tiring. Could the PC then also be used without a cooler, what has me then very surprised. Of course I have clocked down the processor to 2.9GHz. Property me then 2 new fans buy and suitable clips to fix and now I can my i7 2600K 4.3 GHz overclock and I do not exceed 58 degrees Celsius, which completely goes fine.

Installation is eig. Pretty simple. If you have previously installed before a cooler, the installation takes maybe 10 minutes. But would recommend a thermal grease mitzukaufen because the supplied though is okay, but not as high quality, such as a Noctua or similar brands.
