If you have read my review of the new Cooler Master MasterFan Pro 120 Air Pressure already, there’s not much needed to introduce this- the 140 mm version of it. If not, what are you waiting for? I am always eager to check out new 140 mm fans though, and the 120 mm version impressed me. So let’s thank Cooler Master USA, and see how this fares.

At this point, the fans are not up on Cooler Master USA and so let’s take a look at the specs from the product page on Cooler Master Eu website:

Cooler Master provides a decent set of specifications here, and there is also a data sheet for those interested. This is not an LED fan, and neither are any of the other 4 MasterFan fans out so far. This is also a standard 25 mm thick square frame 140 x 140 mm fan, and is intended as a radiator/heatsink fan. The most interesting feature, perhaps, is that the fan has 3 modes which affect the max speed. S (Silent) mode has the fan with an RPM range of 650 to 1550 (+/- 10%), Q (Quiet) mode from 650 to 2200 RPM, and P (Performance) mode from 650 to 2800 RPM. One could argue that Cooler Master is giving you 3 fans for the cost of one, if you were indeed looking for different rated speed versions of the same fan, but we will see for ourselves how it works out in practice. Either way, with a rating of 2800 RPM this is one of the fastest 140 mm fans I will have tested. This uses their POM (polyoxymethylene) bearing which they have used in fans for 2+ years now and is a sealed, FDB style bearing. Cooler Master is quite proud of it and rates it with a life expectancy of close to 500, 000 hours which is more than I have seen anyone else report. But then they go and give this a 2 year warranty thus negating everything and I would really encourage them to increase said warranty to 5 years given they seem to be so confident of the fan.

Let’s take a good look at the fan now on the next page.
