Compact 70mm Case Fan

The OEM Industries MGA7012XR-A25 is a 70mm frame fan designed for tight chassis positions where larger units will not fit. It runs on a standard 12V supply drawing 0.30A through a two-wire power lead. The black plastic housing suits system builders who need targeted airflow without RGB illumination. Ball bearing construction supports continuous operation in desktop or industrial enclosures.

Replaces Worn 70mm Units

This fan serves as a direct drop-in replacement for failed or noisy 70mm coolers of the same thickness and voltage. The jump is worth it when an existing sleeve-bearing fan develops rattle or reduced spin-up reliability. Builders maintaining legacy small-form-factor systems or rack appliances will match the original mounting pattern and connector without rewiring. It does not address builds that require PWM speed control or higher static pressure ratings.

Simple Two-Wire Mounting

Installation uses four standard corner screws through the 70mm frame into any compatible fan grille or heatsink bracket. The two-wire lead connects directly to a 12V header or molex adapter; polarity must be observed to avoid reverse rotation. Common issues include overtightening screws which cracks the thin frame ribs, and routing the short lead past sharp chassis edges without strain relief. No software configuration is required.

Questions about this item

Will the 70mm frame with 25mm depth fit my case fan mount?

The fan measures 70mm square and 25mm thick, so it fits any standard 70mm mounting holes with that depth clearance.

How do I connect the 2-wire lead to a 3-pin or 4-pin motherboard header?

Align the two pins with the outer ground and 12V pins on the header; the missing tachometer pin simply leaves speed reporting unavailable.

When should I expect the ball bearing to need replacement?

Ball bearings typically run for tens of thousands of hours; replace the fan if noise increases or airflow drops noticeably.
