Pros
Cons
I bought this cooler for an old processor (AMD A8-6600K, TDP 100W), with the plan to also use it in a new PC (AMD Ryzen 5 3600, TDP 65W). The cooler completely met expectations: it is very quiet and efficient, the included thermal paste is pre-applied to the cooler's base, so I didn't replace it. In the old PC, the processor temperature was no more than 30°C to 35°C at idle, and in games, the maximum temperature was (in GTA V) - 64°C. - Quiet (Compared to the rest of the system. Without background noise, when right next to the fan, you only hear the airflow) - Price (Compared to competitors in this price category, there is no equal in quality) - Dimensions (The height of the cooler when assembled is only 155 mm. I thought it wouldn't fit in my dinosaur, but luckily it did.) - Quality (I think no explanation is needed here). No disadvantages found in this model. |
Everything is great. I got it for the i5 8400. Cool and most importantly quiet for me, since I'm constantly at the computer. The price matches its quality level. Cold Very quiet, Be Quiet fans are among the quietest Medium in size, does not protrude The appearance is excellent Noticed it with no one else, but mine is slightly loose although I tightened it so much the board bent. use be quiet!

Simply lovely, like all products from Be quiet!! I have both the PSU and all the fans from Be quiet. Silence at 320 - 500 RPM (I don't get more than that), easy installation on the Z 370 motherboard, sits firmly on the processor, very tightly. No |
