Pros & Cons

Pros

  • ✓ 118mm tall, so it fits compact mATX and ITX cases where tower coolers won't
  • ✓ Rated at 23.85 dB(A) max from the 92mm TL-P9 fan
  • ✓ 4-pin PWM fan up to 2200rpm and 32.77 CFM, so the board can manage speed
  • ✓ S-FDB bearing rated for 20,000 hours and built to cut blade wobble
  • ✓ HDT direct-touch copper base with full aluminum fins; mounts for AM4 and AM5

Cons

  • ✗ A single 92mm fan moves less air than 120mm tower coolers
  • ✗ No TDP rating listed, so matching it to high-wattage CPUs is guesswork
  • ✗ LGA1700 is in the title but not the compatibility list; check the bracket
  • ✗ Heatpipe count isn't specified in the listing
