Introduction, Specifications, and Pricing
The second of two cooler to release recently is the big brother of the MASTERAIR PRO 3. While Cooler Master offered a compact cooler to fit into many locations, and at the same time staying virtually silent while doing so, they also realize there is a substantial market for 120mm fan based models as well. That being said, outside of their dimensions, these two CPU coolers are nearly identical. The only change outside of the increased size of this latest model is that there is an additional heat pipe offered in this 120mm fan based cooling solution.
A lot of the technologies carry over with this cooler as well. Cooler Master still opted for the CDC 2.0 base assembly. This is where they get the pipes closer to each other, and then mill them all until there is no gap between the heat pipes, offering an increase in its surface area to contact the IHS. It uses a similar fin stack, increasing air flow through the tower while also limiting resistance to it. It also uses the X-Vent and Air-Guide technologies and comes with all of the same mounting hardware as well. Of course, with increased size built into the tower, and much more air flowing from the fan which accompanies this cooler, performance should improve as well.
The CPU cooler we have been discussing is the MASTERAIR PRO 4, the larger of the two Cooler Master CPU coolers to be released. Cooler Master is expanding the MASTERAIR line of coolers, and while this may not be mod friendly or 3D printing friendly as we saw with the MAKER 8 CPU cooler, you will soon see that it also does not cost nearly as much. The premise here is to deliver a cooler which can handle its business, have a bit of aesthetic appeal to attract buyers, but at the same time, it is likely the pricing that will sway your vote in the direction of this cooler. If you liked our review on the MASTERAIR PRO 3 but find the cooler is not up to your demands, stick it out for a bit, and see just how well its larger cohort does as we get up close and personal with the MASTERAIR PRO 4.
Just as we did its little brother, when it came to the chart for this MASTERAIR PRO 4, we copied what we found on the side of the packaging. From what we can see, all of the latest sockets are supported, including many of the aging sockets as well, delivering excellent compatibility across the board. With the fan included, the MASTERAIR PRO 4 is 84mm thick, 129mm wide, and stands 158.5mm tall. Without the fan included, the height remains the same, but its thickness is reduced to 60mm, and without the fan clips, we reduce to 116mm in width. As to what the cooler is comprised of, we find there are four 6mm diameter copper heat pipes. At the base, which its main section is made of aluminum, under that is where the CDC 2.0 comes into play. As for the stack of 57 fins, they are all made of aluminum. As to the weight of the MASTERAIR PRO 4 the cooler is only 472 grams, and raises to only 630 grams once you add the fan and clips into account.
The fan which ships with the cooler is the MasterFan Pro 120 AB which sports the model number FA12025L12LPJ006. Also like where the 92mm fan came with a micro switch on the back of it, this model does as well, but along with Silent and Quiet settings, this time there is a Performance option as well. This fan can spin in a range of 650 to 2000 RPM, and at the maximum speed, it can deliver 66.7 CFM of airflow and 2.34 mmH2O of pressure. If left at the mercy of the PWM circuitry, the lifespan is huge at 490,000 hours. Cooler Master also mentions that if the fan is run at its full speed for the entirety, the lifetime shrinks drastically to 70,000 hours. Noise can be minimal, as it is rated to start at only 6dBA, but at full speed, these fans can get loud as the noise increases to 30 dBA. This 120mm fan uses a 4-pin connection and sips power over its 12V line. Also, just like the MASTERAIR PRO 3, the MASTERAIR PRO 4 is also backed by a five-year warranty.
What may shock you, as it did us, is that to jump from the compact design to this much larger version, you only need an additional five bucks. Since we are writing this before the actual release of the cooler, we were unable to find them in retail locations, which is no surprise. In various emails back and forth with Cooler Master, they were sure to inform us that this MASTERAIR PRO 4 comes with the MSRP set to just $44.99. It is near nostalgic to see this again, where you get a cooler with excellent specifications, and it still can be had for less than $50.
Cooler Master is proving, quality, performance, and affordability that can all be had on the cheap, and if you are in the market for a new 120mm fan based tower CPU cooler, the MASTERAIR PRO 4 hits all the marks so far and is worthy of the asking price.
