Questions about this item

How often should the HK120 fan be cleaned or replaced to keep my GX620 running cool?

Clean the fan blades and heatsink every six to twelve months with compressed air; replace the unit if bearings become noisy or airflow drops noticeably.

What thermal limit will the HK120 hit first during a long compile on a GX745?

The fan spins at a fixed speed, so the CPU temperature ceiling is reached before the fan can ramp higher.

How much noise and heat does the HK120 add when the GX755 runs all day?

It produces a low, steady hum typical of a 120 mm case fan and moves enough air to keep internal temperatures stable without adding measurable heat.
