CM_S542V.2_DimensionsIf you are reading this on a mission to replace your stock CPU cooler, take a moment.  With any new hardware purchase be sure to check and make sure your current case and hardware configuration will allow the new upgrade. In this instance size is the factor, it never hurts to get a ruler or tape measure and get eyes on how much clearance is available inside your current PC case. It’s obvious a lot of thought went into the sizing and design of the GeminII S524 Ver.2 and it should fit nicely inside all but the tightest of enclosures. Note also the excellent RAM clearance, no worries there.

Inside the BoxCM_S524V.2_1

Upon opening the box we are greeted with a nice Silencio FP 120 Fan presentation, this ohh-ahh moment was broken when we noticed a super bubbly logo sticker in our face. Took only a moment to smooth out the bubbles with a thick card, but we shouldn’t have had to. However, we are confident this was a rare anomaly and you certainly shouldn’t worry about being greeted with ol’ bubble face.


Fully unpacked we get:

  • GeminII S524 Ver.2 with Silencio FP 120 Fan
  • Universal Intel/AMD backplate
  • Mounting hardware for Intel platforms LGA 2011-3/2011/1366/1156/1155/1150/775
  • Mounting hardware for AMD platforms FM2+/FM2/FM1/AM3+/AM3/AM2+/AM2.
  • Nifty little wrench for installation
  • *Full tube of thermal compound
  • User Manual
  • Warranty Information Manual

We couldn’t find any company stickers included. We love stickers, you love stickers, every product from every company should include stickers.

*Some companies will provide a pre-applied thermal compound with their cooling hardware, good for a single application. CoolerMaster did the cool thing and provided a tube of compound for you to use for future builds, or to share with that one friend who never seems to buy any. Thanks CoolerMaster.CM_S542V.2_FanMountsWith the Silencio FP 120 fan off we can see once again CoolerMaster is thinking about upgradability as you get mounting holes for both 120 mm and 140 mm fans in case you would like to upgrade later on.

CM_S542V.2_RamClearanceA picture tells a thousand words, this one told us: The GeminII S524 Ver.2 is made with proper clearance to not interfere with your RAM purchase of choice, big fat heat shields and all. The top-down design also helps cool your RAM and motherboard. See those big red MOSFET coolers? They can get hot too, the GeminII S524 Ver.2 can be mounted in varying positions, allowing you to choose where you would like to cool inside the case.

CM_S524V.2pipes_15 Continuous Direct Contact copper heatpipes combined with shaped aluminium cooling fins do a great job of dissipating heat effectively. We note the contact surface as being near perfect with almost zero gap between pipes.

CM_S524V.2Xtemp_1Moving along we see the X-Vents and Air-Guide design. The law of the universe says everything works best at 45 degree angles and it seems CPU cooling is no different. The X-Vents not only look cool but efficiently guide heat away from your CPU.


For testing it was decided that a consumer looking for a CPU cooler in the GeminII S524 Ver.2’s price range would most likely not have the ultimate latest Skylake or X99 game machine. To give a more “relevant to the people” score we decided to test on an i7-860, A platform we imagine is closer to the spec of the average user. For CPU load we ran our favorite demanding games in real world scenarios. As you will see below the GeminII S524 Ver.2 had one job and it passed with flying colors.


The GeminII S524 Ver.2 is a good product that does an excellent job, but it’s not a top performer.

Final ConclusionsCM_LOGO

The GeminII S524 Ver.2 offers a solid choice for CPU cooling. Featuring all the attention to detail, style, and performance we’ve come to expect from CoolerMaster on everything from the flagship hardware right down to the budget builder.  We love when a PC component does exactly what it is supposed to do, when the design is calculated and offers options, especially upgrade options. The GeminII S524 Ver.2 has the aesthetics as well, when you get it out of the box you’ll feel like you finally got your first shiny after hatching 300 eggs. While we surely like the GeminII S524 Ver.2, we must note there are closed loop liquid cooling systems availableAward_Bronze from reputable companies for the same price. Thing is for closed loop systems at this price range we don’t expect to get much better temps, combine that with the added component cooling benefits, upgrade options, slick style, and ease of use, the GeminII S524 Ver.2 comes out swinging as a heavy value contender.
