Excellent ventirad
After my pure rock 2 on my i5-8600k, used to and convinced by be quiet products, I'm not disappointed.
Easy installation, although I was apprehensive (thanks to the official supplier's YouTube video for reassurance and guidance).
The screwdriver in the package is really appreciated.
In terms of performance, I was told in the shop that my i5 14600K was running at 85 degrees because "these processors heat up".
Verdict: it doesn't exceed 55 degrees even after 3 hours of intensive gaming on the latest games. Space Marine 2, which is CPU-hungry, and God Of War Ragnarok. And I'm playing at 3440x1440.
As far as noise is concerned, I can't even hear it. I tested it at full speed, and it's still quiet, given the speed and the pair of fans. You wouldn't expect anything less from be quiet.
I'd also like to point out that I have a large tower case, which must help with ventilation.
So, really top notch, I'd recommend it without hesitation.
PS: I would warn you that in my high-end case, it reaches the limit in width (near the glass) and opt for low-profile ram strips without LEDs, it will go over the top. On this subject, the fact that you can raise the fan to go over the ram during assembly or if they're too big is really great.
