SXDOOL

SXDOOL rl4z 135mm case fan 12V .33A 1700rpm 135x135x25mm

SKU CH-ZV79-VDDV9 MPN rl4z

12 V 135 mm case fan with double-ball or oil-seal bearing runs at 1700 rpm and draws 0.33 A

  • 12 V .33 A draws little power for efficient cooling
  • 1700 rpm airflow keeps chassis temperatures low
  • Double ball bearing design extends operational lifespan
  • 135 mm frame fits standard 120 mm mounting holes
  • Two leaf colour options suit different build aesthetics

135 mm case fan for chassis cooling

The SXDOOL rl4z is a 135 mm square frame fan designed to move air through PC cases and similar enclosures. It runs on a 12 V supply and draws 0.33 A at its rated speed of 1700 rpm. The unit suits builders who need a direct replacement for an existing 135 mm mount.

Double ball or oil seal bearing at 1700 rpm

Two bearing variants exist: the B1352512H uses a double ball bearing while the S1352512H uses an oil seal bearing. Both spin at 1700 rpm from the same 12 V .33 A input. The short 12 cm lead keeps cable routing simple inside compact chassis.

White or silver blades with 120 mm hole pattern

Each variant ships with either white or silver blades; all other specifications remain identical. Mounting holes sit on a 120 mm square pattern with a 171 mm diagonal spacing. The small 2-pin interface on the S-model connects directly to standard headers.

Questions about this item

How do I mount the rl4z fan and which screw spacing should I use?

Align the fan with the 120 mm parallel-hole spacing or the 171 mm diagonal spacing on your chassis, then secure with four 135 mm fan screws.

When will the rl4z bearing need replacement?

The oil-seal bearing on the S1352512H model or the double ball bearing on the B1352512H model will typically last several years; replace the fan when noise or speed drops noticeably.

At what point does the 12 V .33 A power draw limit the fan under sustained load?

The motor is rated for 0.33 A at 12 V, so sustained operation at 1700 rpm stays within that limit; exceeding the rated voltage would be the first constraint.
