Following up with my review of the CM Hyper 612 Ver. 2 CPU cooler, it is now time to take a look at another revised cooler- this time from the GeminII series. This is my first top-down cooler and it definitely is different from the usual AIOs or tower style air coolers. For one, this allows for the usage of relatively large 120 and 140mm fans in a small profile. On the other hand, top-down coolers are usually associated with low TDP CPUs because they tend to have a lower heat dissipation surface area compared to bigger tower style heatsinks while also sticking to 1 fan more often than not. The original S524 had nickel plated heatpipes, a nickel plated flat copper cold plate and used an older Blademaster style fan. This new version, among other subtle things, employs copper heatpipes and a continuous direct contact system as seen in the Hyper 612 V2 and, possibly the most important, comes with their new Silencio 120mm fan which has had people rave about already. Thanks to Rajiv from Cooler Master, we have the opportunity now to take a good look at this cooler.

Let’s begin by taking a look at the specs courtesy the product page:

Once more I am glad to see that Cooler Master has a lot of detailed specs listed out here. Even things like the dimensions of the package that it comes in is helpful to know for users like me- I know now, for example, that this would not fit in my mailbox at home and so I have to arrange for the delivery person to drop it at my door or have to pick it up myself. I encourage everyone to put up as many specs up as possible irrespective of how useful they seem to be at the time. They are missing a few things like RAM height clearance though which is a big omission in my opinion, and there are a few things put elsewhere such as the fan current rating next to the power draw rating. But I will not fault them here given that the product launch in North America is supposedly today itself and my contact at Cooler Master took down all these notes and said he would get the product page filled out correctly soon. In fact, if you notice that the product page has been updated by the time you read this then you know they have listened to feedback.

Now if you compare these specs from those listed on the predecessor’s product page, you would see that the heatsink is different also. The S524 original has a heatsink coming in at 144 x 144 x 78 mm vs this one at 136 x 124 x 77 mm. This also results in the newer heatsink being a lot lighter too (392g vs 490g). One thing I did notice missing was the technical drawing of the cooler with all the different dimensions listed out. But I was able to get it from the CM China website so here it is for the S524 Ver. 2:

Hope that helps people out. To quickly see what the changes were, here is the technical drawing for the S524 original:
