I took the Arctic Alpine as a replacement (the speed controller died: either it didn’t start, or it barely rotated at any t). They brought it the next day, changed it in 10 minutes. And I forgot about it . (the best characteristic of a good spare part). At first, I occasionally glanced at AIDA, then "scored" - it works, and all right. Pros: Convenient fastening, got up without straining. Relatively quiet, only when video processing becomes audible. Convenient form - memory (I have high standards) does not interfere with it. With its cons: I did not notice that the cooler gave out the declared 2400 rpm. Video processing, t=70°-80°, starts "beeping" the BIOS speaker - and in Aida you can see its 1900-2100 rpm MAX.
