Dual 92mm fan CPU

Dual 92mm Fan CPU Cooling

It is recommended to choose a high quality fan for this modification. Also, ensure adequate airflow through the chassis.

Fans Used

• Noctua NF-B9 PWM
  • Tested by q66 on single 18 core system. Reports lower max temp and lower noise levels vs stock, under stress testing. Achieves max turbo boost.
• Noctua NF-A9 PWM
  • Pending testing by nashimus on dual 18 core system, SC747TG-R1400B-SQ chassis. More photos/info to come when board is back from RMA.

Attaching The Fans

(Noctua NF-A9 Pictured)

Attached using a thin, but stiff, solid stainless steel wire to connect to partially inserted fan screws. An "H" pattern is used to keep the fans aligned with the heat sink.

The fan is a little crooked in this photo from being handled. An additional strand could prevent the fan from moving, but it doesn't seem necessary at this point. The fans are already pretty snug.

Due to the placement of the heat sink retention mechanism, the fans stand about a centimeter above the top of the heat sink.
