Compare CPU cooler measurements by test condition. Air and liquid coolers are ranked separately because their overall performance scores use different reference coolers. Relative performance is measured against the best complete result within the same type and condition.
THETA cooler performance: separate Air and AIO ladders per platform, using the measured Overall Performance (OP) at 30 dB(A), or at 25 dB(A) for coolers that cannot reach 30 dB(A). THETA is a Cybenetics performance rating. It is not part of our ISO/IEC 17065 certification schemes and is outside our accreditation.
