I hesitated with other more expensive models and supposedly a little better but the level of net perf tests are too detailed for the 80% of us and therefore not really useful. suddenly I did not want to invest too much money for my old 775 chipset but I wanted to reuse the same qd in a future change of processor, and have a rad énormissime not either. Results: no sound with my C2D 6750 rose to 3550Mhz. even with OCCT and fan in 'silent' that does not exceed 58 °. but happiness and fan is compatible with all the chipsets of the moment. One downside: disassemble the motherboard to fix the screws at the back. but hey it's a youthful, 1h taf and here we go for long. not are spending more for the same in larger more expensive and often less effective.
