Cooler Master GeminII S524 Version 2 CPU Cooler Review

Cooler Master's GeminII S524 Ver 2 CPU cooler won't have you setting any overclock records, but its price and silent operation are big positives.

Cooler Master GeminII S524 Version 2 CPU Cooler Review 99 |

Considering the last CPU cooler we saw from Cooler Master was an AIO, we are completely changing gears in cooling types, and even getting a bit of a history lesson at the same time. This is because the latest cooler for them to release is a visit back to the GeminII series of coolers, which we have not seen in what seems like forever, but with all the movement towards smaller and smaller cases, Cooler Master wanted to offer an updated cooler to suit the needs of users who cannot fit a tower cooler or even a 120mm AIO.

The original version of the GeminII S524 offered things like a solid copper base, good memory clearance in a C-style cooler design, yet staying at 105mm in height. It also offered things like Nickel plated heat pipes, and a fan more than capable of handling the processors of its day. The thing is, with this latest version of this cooler, a lot of what we are discussing has changed in favor of other ways of accomplishing the same sort of performance, while lowering the volume, yet still delivering a cooler that is up to date, and able to fit where others cannot.

As we look at the GeminII S524 Ver 2, we find a very familiar cooler in our hands, yet there is definite differences that you will notice right away, and others that are not so obvious. The thing is about this cooler though, while it may be an attempt to offer a better product from the original design, the one thing that customers will love on top of all else is that the pricing hasn't changed since 2011 when we last saw a cooler with this same name.

While this chart is loaded with information, there are the main components and their makeup left out, so we will get that out of the way as we move through the top of this chart. The RR-G5V2-20PK-R1 or GeminII S524 Ver 2 CPU cooler will fit anything AMD including AM1 and anything after that, and for the Intel side of things, it fits anything LGA775 or later. The S524 Ver 2 is comprised of a group of 41 short fins next to another group of 21 longer fins, all made of aluminum, and all are pressed onto the ends of five copper heat pipes. These pipes take the heat from the CPU via CDC Technology where they use an aluminum plate to house the copper pipes, but the pipes are milled to make Continuous Direct Contact (CDC) with the IHS. This design is 144mm long, 141mm in width (3mm skinnier than the original), and stands 105mm tall, well technically 105.4mm when looking at the dimensional drawings of it.

To cool this 392 gram cooler, Cooler Master has chosen to go with the 120mm Silencio FP fan. This fan can spin up to 2000 RPM, but delivers slightly less air flow at 65CFM where the original was at 77. The thing we get from this though is that this fan is more silent in operation with only a 22 dB(A) rating offered, and they also ramped up the pressure to 3.33 mmH2O over the older 2.4 rating. This fan spins on a Loop Dynamic Bearing and offers 160,000 hours of run time, and at the same time using less than a tenth of an Amp and under a Watt of power. It is odd though that there is no mention of the 140mm cooling option built into this cooler. The last thing most customers will need to know about this cooler is that it comes with a two-year warranty against workmanship and defects or failures during "normal" use.

As we mentioned earlier, it is the pricing that will attract many potential customers to this cooler. We used to say back in the day that $50 could get you a really good air cooler, and today that pricing has moved much closer to the $100 mark. Considering that Cooler Master is able to, some four years later, deliver a revision of an older design at the exact same price point is near an astonishing feat considering material costs had to have gone up along the way as well. The fact that we can find the Cooler Master GeminII S524 Ver 2 with an MSRP of just $39.99 in today's market is great to see. You will have to spend just a tad more to get one to your door though, as actual listings show this cooler is $42.47 with free shipping at Amazon at the time of writing.

After a year of gaming, Chad caught the OC bug. With overclocking comes the need for better cooling, and Chad has had many air and water setups. With a few years of abusing computer parts, he decided to take his chances and try to get a review job. As an avid overclocker, Chad is always looking for the next leg up in RAM, cooling, as well as peripherals.
