Temperatures
65W Processor
Despite a more violent 65W profile, the latter still represents the least stressful phase of this protocol. It allows to highlight the performances obtained with compact/entry-level heatsinks. These results are only indicative for the largest heatsinks (AIO, large dual tower, etc.).
When it comes to temperatures, at full speed, the Pure Rock LP does slightly better than its Noctua counterpart. At mid-range, the be quiet! model is at the same level as its Austrian rival, only to lose face at low rpm. In our opinion, this is because the fan lacks pep on its slowest speeds. Moreover, we realize this when we mount the small NF-A9x14 PWM of the NH-L9a chromax.black. Moreover, in this configuration, it is now slightly better than its equivalent from Noctua.
Our series of readings will stop with the test with a consumption of 65W. This kind of heatsink is not strong enough to hold on our processor consuming more.
Summary
In summary, we find here a rival to the NH-L9a chromax.black from Noctua because of its size. On the other hand, if it does a little better at high speed, the performance of the fan collapses at low speed. This is noticeable when you change the fan of this little Pure Rock LP.
