Intel Core Ultra 9 285K, OCCT for about 6 to 10 minutes, thermal paste Noctua NT-H2, 23 C room, test rig not named in the text, radiator at the top. The temperature chart shows 81 C load (idle 33, average 38). Noise load 55.8 dBA (idle 30.4) from an ExTech HD600 meter 10 to 15 cm above the radiator with the system fans off, so it is not comparable with 1 m figures. The PWM fans run at the highest speed under extreme load without an external controller.11Reviewprofesionalreview.com/2025/12/01/be-quiet-pure-loop-3-review/ampRead 15 October 2026ProfesionalReview, review of 2025-12-01. AMD Ryzen 5 7600X on an X670E AORUS Master, bench not named, ambient 24 C, 24 hour stress test. Row 1: PPT limited to 80 W, PBO manual with Curve Optimizer -25, 60 C with the peaks almost identical. Row 2: stock settings with PPT at maximum (142 W), about 88 C almost constant and below 90 C. The text says the peak power was 134 W in the test section and 138 W in the conclusion, so the power is not stored for row 2. Noise 36 dBA is the stress-test level with the stock CPU, measured with a sound level meter 50 cm from the bench in a 30 dBA room. Fan speed and paste are not stated.12Reviewigorslab.de/en/be-quiet-pure-loop-3-schlicht-leise-effizient/3Read 15 October 2026Igor'sLAB, Enrico Steinert, review of 2025-09-09. AMD Ryzen 9 7900X on a ROG Crosshair X670E Hero on an open bench table, room 19.0 to 20.5 C, Prime95 30.8b17 Small FFTs for 1200 s, HWiNFO64 CPU Die (Average), the same thermal paste on every cooler applied with the X-Apply tool (paste brand not stated). Noise was measured with a Voltcraft SL-10 at 40 cm in a room of 30.4 dB(A): 47 dB(A) at 100% PWM. The limits tested were 100, 150 and 200 W. The 200 W row stores the 60 K delta over ambient from the conclusion page, which does not say which fan setting it belongs to. The Maximum RPM chart ends near 60 K and the 40 dB(A) chart near 61 K, so the row is stored under 100%. The 200 W is the CPU power limit, not a measured draw.
