Compact 12 V frameless fan

The Zyvpee DFB351012H is a 12 V DC frameless case fan rated at 1.7 W. It uses a two-wire power connection and a ball bearing for smooth rotation. The 31 mm square frame suits tight spaces on graphics cards or small CPU coolers where a traditional framed housing will not fit.

For confined GPU or chipset cooling

Builders fitting a low-profile graphics card, a compact CPU cooler or a chipset heatsink can use this fan where height is restricted. The lack of PWM control and the fixed 12 V supply mean it runs at a constant speed, so users who need automatic speed curves or near-silent idle operation should look elsewhere.

31 mm frameless footprint

The 31 mm frameless outline is the single dimension that decides whether the fan will mount on your cooler or PCB. Measure the available clearance and hole pattern against that footprint before ordering.

Questions about this item

How is the 31 mm frameless fan mounted without screw holes?

The frameless body relies on friction fit or adhesive pads inside the CPU cooler shroud; the step most people miss is cleaning the mounting surface so the fan cannot shift and vibrate.

What maintenance does the ball-bearing 2-wire motor need later?

Ball bearings are sealed for life; no lubrication is required, but dust should be blown off the blades annually to keep the 1.7 W draw steady.

What limit appears first when the 12 V fan runs continuously at full speed?

The 1.7 W power envelope caps airflow; sustained load hits that thermal ceiling before the ball bearing reaches its rated life.
