120 x 25mm Cooling Fan + Wire Guard - Medium

This 120mm fan is a square 120 x 25mm unit with a chrome wire finger guard and wire leads. It’s Blue Alpine part E00119-00, $14.60, and it’s listed for the Medium Select. That listing is as far as our information goes. We can’t tell you where it mounts or what it cools, so this page sticks to matching it against the fan you’re replacing.

Sizing up a 120mm fan

Fan sizes are quoted as frame width by depth. This one measures 120mm along each side of the square frame and 25mm front to back. That’s the usual depth for the size and the same format found in a lot of computer cases, which is why 120mm fans are so easy to come by. The computer fan article lists the standard sizes.

Measure your old fan with a ruler or calipers before ordering:

• Width along one edge of the frame
• Depth from the front face to the back
• Center-to-center distance between two mounting holes on the same side
• How many wires come out, and what’s on the end of them

If width or depth is off, it’s a different fan. The hole spacing has to line up with whatever you’re screwing it to.

What you get

• One 120mm fan, 120 x 25mm, with wire leads
• One chrome wire finger guard
• Blue Alpine part number E00119-00

Read the label on the old 120mm fan

Most fans carry a sticker on the hub with the voltage and current. That label matters more than the size, because a fan on the wrong voltage either crawls or burns out. Write down what your old one says. If you can’t read it, or you want us to confirm it against this part, send a photo through the support contact form.

Wire count tells you something too. Two wires means power only. A third wire usually carries a speed signal, and a fourth adds speed control. If your old fan had more leads than you see in our photos, check with us first.

Which way the air goes

Fans push air one way only. Many have small arrows molded into the side of the frame, one for rotation and one for airflow. Before you remove the old 120mm fan, look for those arrows or take a photo showing which face points where. Fitting the new one backward is the classic mistake on a fan swap. Both faces look nearly alike, so it’s easy to do.

The wire guard

The chrome guard keeps fingers and loose wires out of the blades. It comes with the fan, so there’s no need to move the old one across. Put it on the same face the old guard was on. A bent guard that touches the blades will tick as they turn.

Fitting the new 120mm fan

Unplug the dryer before you open anything. Photograph the old fan, its leads and the way they’re routed, so the new leads go back the same way and stay clear of the blades. Fan frames are usually plastic. Tighten the screws until they’re snug and stop there, or you’ll crack a corner or strip a hole. When you’re done, spin the blades by hand to confirm nothing catches.

Signs a fan is on its way out

Noise is usually the first clue, since fan bearings wear gradually and get louder as they go. Grinding. Ticking. Blades that wobble on the hub. A fan that needs a nudge to start, or runs noticeably slower than it used to. Heavy dust on the blades also cuts airflow, so clean that off with the power disconnected before you decide the 120mm fan has failed.

A worn 120mm fan rarely recovers. Oiling a sealed bearing might quiet it for a week, but the money is better spent on a new one.
