Thermal Performance Audit
Structured airflow and temperature survey for active mining shelves, identifying fan wear and duct misalignment before hash boards throttle.
View detailsWhy Field-Replaceable Fans Matter
At 0.05 TH/s and above, a single seized bearing can throttle an entire shelf. Cartridge-style fans let us restore airflow in minutes.
No Board Removal
Cartridge mounts release from the shroud exterior. We replace the fan module while hash boards stay seated and powered down safely.
Matched CFM Specs
We stock OEM-equivalent modules rated for the static pressure your duct layout demands—not generic case fans that fail within weeks.
Documented Thermal Recovery
Every swap includes before-and-after inlet temperature readings logged against your facility baseline.

What Operators Say
We had three S19 units running 8°C above rack average. Filehemlockpath swapped all six intake cartridges in one afternoon visit to our Sasang warehouse. Hash rate stabilized by evening—though they noted one shroud had hairline cracks we should monitor.— Min-jun K., small-scale hosting operator, Busan
Their thermal audit caught a misaligned duct before we lost a board. The written report was detailed enough to share with our landlord's HVAC contractor.— Hye-jin L., co-location manager, Gimhae
