DBPJ1238B2G AVC 12cm 6-Pin Cooling Fan for Innosilicon T2T
The DBPJ1238B2G is a 120x120x38mm 12VDC cooling fan made by AVC for the Innosilicon T2T miner. Rated at 3.12A current and 7000 RPM with a 6-pin connector and a ball-bearing motor, it delivers the high-static-pressure airflow needed to push air through the T2T's densely finned hashboard heatsinks.
The wide-angle blade profile and reinforced 38mm-thick frame minimize chassis vibration while moving the airflow volume the T2T thermal design expects. A failed or seized 12cm fan is the leading cause of hashboard throttling on aging T2T units.

Compatibility
The 120x120x38mm form factor and 6-pin connector match the front/rear fan positions on the Innosilicon T2T chassis. Confirm the connector keying on your existing fan before plugging in — Innosilicon and AVC also ship 4-pin variants on adjacent models. For Whatsminer M20 / M21 12cm 6-pin alternatives, see the KZ14038B012U and KZ12038B012X listings in related products.
Where the fan fits
The 120x120x38mm aperture is the standard T2T chassis fan slot. The 6-wire connector carries 12V, ground, tach and PWM-class control signals back to the T2T control board — the board both reads RPM and modulates speed under load. Verify that the upstream 12V rail can supply 3.12A continuous per fan before installing.
Common failure symptoms
- Miner dashboard reports a fan-stop alarm at boot or under warm-up
- Audible bearing rattle or knocking from the 120mm fan slot
- Hashboard temperatures climb past throttle threshold under load
- Dust impaction blocks the fan rotor, stall under load
- Fan spins up but stalls — typical of a tired ball bearing on aging units
Frequently asked questions
Will this fan fit a Whatsminer M20 / M21?
The KZ14038B012U is the dedicated 14cm Whatsminer M20 / M21 6-pin fan — see related products. For 12cm Whatsminer applications, check the connector keying carefully before substituting.
Is the 6-pin connector PWM-capable?
The 6-wire pinout carries control and feedback signals consistent with the T2T control board's fan management. Match keying and pinout to your specific control-board fan header before installing.
How many fans does the Innosilicon T2T use?
The T2T chassis is typically equipped with two 120mm fans (front and rear push-pull). Replace as a pair when one fails — the surviving fan is usually equally fatigued.
Can I run the DBPJ1238B2G at lower RPM?
Yes, via the control board's PWM input — though under-driving the fan reduces airflow and may trigger temperature throttling under hashing load.
