Montech AX120/140 PWM White ARGB Fans Review

A Closer Look

First impressions are good, as affordable as these fans are, they certainly do not look or feel like a cheap product. I mean, there’s nothing in the way of accessories, the cables are hard-wired, there are no extension cables or anything, but you’re paying for a fan and you get a fan, so I don’t see anything overly problematic about that.

The white colouring looks great, nice and bright, a little glossy and a little matte, but overall a very clean look. There’s a stamped Montech logo on the 120mm model (more on that shortly). The LEDs are built into the surround of the fan, rather than into the fan itself, so you’ll get more of a fixed light rather than it illuminating the blades. I actually prefer this accent light approach, it’s a little more interesting to me, but if you want fans where it’s the actual fan that’s ARGB, you’ll be left disappointed here.

Up in the corners, you’ll find four thick rubber rings on each side of the fan, giving us eight in total. These will help soak up any vibrations from the fan or your computer and prevent the hard plastics of the fan from making contact with the hard surfaces of your PC case.

The fans are hard-wired and come with a 5V ARGB header, as well as a 4-pin PWM header. However, there’s no Y-splitter or pass-through, so you can’t daisy chain the fans without some additional hardware, this isn’t a problem for cases that come with a hub, but if you only have say 2 ARGB headers on your motherboard and four fans, you’ll need to buy a splitter or daisy chain cable.

The fans are case fans, so you simply get four screws to put them in place, pretty straightforward stuff really.

Around the back, the fan is nicely designed, with the all-white cables being neatly routed right into the central motor housing.

There’s a sticker on the back with a little rainbow colour on the edges, and all the usual model numbers.

I like the back of the fan surround too, its shape helps further increase the overall airflow, but keep in mind these are high-airflow fans with a lower air pressure, built for cases, not for coolers or radiators.

The 140mm variant looks pretty much identical, only it’s a little bit bigger, but overall, it still has an identical 9-blade design, it just operates at a slightly lower RPM, but will still move more airflow overall.

Which one is right for you really depends on what your case supports, but 140mm fans tend to move a lot more airflow at lower RPM and run quieter, so I tend to go for larger fans anywhere they’re supported.

Like the 120mm model, the back of the fan is the same and again has that rainbow ring on the rear sticker.

But weirdly, it looks like they either forgot to put the sticker on the 120mm model, so they don’t actually match the aesthetic of the 140mm front the front, which I think it absolutely should.
