I am more than satisfied. get on a fractal design on a r4 intel i7 5820 via a motherboard asus x99. I'm bluffing I am at rest between 25 ° and 28 ° degrees I get full 42 ° degrees. I have not yet tested in overclocking pc .my say if I believe it will go up to around the 50 degrees. for the radiator no noise and nothing to report. the only negative! the rather noisy fan on medium and very noisy diet full max.je exchange by be quiet and here the silence and gold.
