Cooler Master MASTERAIR PRO 4 CPU Cooler Review

Final Thoughts


Even though our sample was slightly askew due to some rough shipping to our door, it did not make any difference once the cooler was mounted, in appearance, or in performance. The MASTERAIR PRO 4 is a solid cooler with a well thought out design, and it is easy to see by our results, you do not need to spend $100 to get good results. Being based on a 120mm fan brings added size, and better performance comes along with it, but when it comes down to brass tacks, the mounting hardware helps in what makes for an all-around good cooler.


Cooler Master has picked some simple to use bits, and with this cooler, as long as you have a screwdriver handy, it installs easily. Also, even though you do not have to break the bank to obtain this cooler, we do have to give it credit for looking as good as it does. In this price range, we expect plain aluminum top fins, and a basic fan with no style, and some wire fan mounting clips. Cooler Master is sure to raise the bar, as the MASTERAIR Pro 4 is not some basic plain Jane offering we would typically see at this price level.



While the MASTERAIR Pro 4 may not be as fancy as other coolers, even those from its series, but that does not mean we have to suffer in the "OMG, look at that cooler" category. Thermal performance is great, and obviously, this cooler takes advantage of the CDC 2.0 technology, the fin design and the X-Vent technology used around the staggered heat pipe layout. Considering the 120mm fan delivers less than 70 CFM to cool this tower, there is a lot of transfer for the flow. It wasn't until we disabled the PWM control of the fan that we found any real noise coming from it worthy of discussion.


At 34 dB in our initial overclocked run, anyone can deal with this limited amount of noise without much issue at all. If you do plan to run the fan at full speed, keep in mind the lifetime of the fan is drastically reduced, and you will be dealing with a loud hum coming from inside of your case.


As you read this, the stock of this cooler should be on the shelves so that you can leave here and start looking for the best deal to be had. Requiring just $44.99 for a cooler which performs this well, looks as good as it does, and is even able to stay near silent even under heavy loads, is the trifecta in CPU coolers. As long as the MSRP holds and retailers stick to what Cooler Master thinks this cooler is worth, you are in for a serious deal in single tower 120mm fan cooled options.


The MASTERAIR PRO 4 can keep up with better-equipped solutions, and in our mind, is a cooler that should be on your list of affordable go-to alternatives, as the Cooler Master MASTERAIR PRO 4 proves you do not have to sell a kidney to get great CPU cooling results.
