Good thing it isn't around April Fool's Day:

Hey, it weighs less than a kilo, that's something.

Not (yet?) available for sale in the US.

Ha. I think this must be the ultimate conclusion to "bigger is better".

Looks good, and it apparently doesn't extend past the top of the board, so it may be a relatively easy fit. The fins don't look too close together, so it may work in a super low-airflow setup.....read quiet. Notice the bracket on the top edge.....a stabilizer of some sort, maybe necessary for such a massive heatsink. This thing would just drop right in my latest positive pressure project.....

Is that flange on the top so that you can attach it your power supply? The holes look like the appropriate size for those screws. Otherwise I'd be afraid of it snapping my motherboard in half.

If you don't mount any fans it's under a kilo...

Hello,

I'll bet that the bracket screws to the brace that is just under the PSU in many cases -- which would be a good thing. I wonder how well the fans would fit near to the side of the case?

holy good god what will they put out next ... y would u ever need a heat sink a third of the size of ur motherboard (plans on buying it when it comes out) the only thing i see a problem is mounting the fans... how close to will they be from the side

This heatsink was already released in Japan, by *Cooler Master*.
It's HUGE!

Edit: Oops, wasn't Scythe.

This thing looks really awful, but I'm seriously considering about getting one

You know, that upper left picture looks an awful lot like a Coleman Stove, doesn't it?

any guess on release date in the us

Remember when Intel said that the "Netburst" architecture would hit 10GHz, I think that Coolermaster still thinks it will happen - 800 Watts anyone.

I'm more interested in how tall it is..

Edit:

Darn it, 3 mm too tall!
175x124.6x81.5mm

The Europe page says March, still no mention on the CM USA site.

Looking at the pictures with the fans installed......What a convoluted airflow setup. Just what will the rear case opening be doing? There doesn't look to be enough room for an internal case fan. If you mounted the rear fan outside the case, blowing outward or inward, you would upset the airflow of the CPU fans.....what a mess.

I'd probably close off the rear case opening and come up with a different solution......

Looks like effectively the same airflow situation you get with an SI-128, SI-120, SI-97, or Big Typhoon. For that matter, it's more or less the same airflow situation you'd get with an XP-120 or similar. (Amazing how quick we've gotten used to tower-style setups, isn't it?)

Also, anybody else notice that that thing isn't actually as big as the two fans? They hang over the ends of the heatsink, it's only 175 mm long. 65mm worth of fan will not even be blowing on the heatsink, and it'll be 65mm of blade, not hub.

Would 92mm fans be more effective? If you have a perforated side panel like the CM Stacker 830 series would a sucking setup be more effective?And given the 830's 4 120mm fan bracket on the side, why mount fans on this cooler at all as pictured on the CM-Europe site? Worth noting that this case now has a large vent on the bottom and top, so it seems like there should be some sensible option.

Kremmit · Post by **Kremmit** » Fri Feb 02, 2007 9:53 pm

92 mm fans would be closer to the "right" size on length, but wouldn't cover the whole width.

Hexus has a review up, with pics. I downloaded the 3rd pic to my desktop as a .BMP (3MB) and took my time making some measurements.

The actual cooling grid width is the right size for a 92mm fan! The specified 125mm width includes a metal "foreplate", much of which contains no cooling fins. The other direction is slightly smaller than 2 times 92mm as far as the cooling fins are concerned. The fin spacing appears to be approximately 1.87mm, about the same as an XP-90 and a little tighter than the Freezer 64's 2.0mm.

The metal "foreplate" contains 4 holes only, on a 118.75mm square. I believe this will allow mounting my "140mm" Aerocool 25mm fan, with the center of the 3 hole spacings that fan provides.

There are no holes for mounting 120mm fans anywhere. In fact, Coolermaster's site specifically shows 120mm fans being slid from side to side so one can mount whereever one wants. Perhaps masking tape is intended to be used?

The "foreplate" can be unscrewed, leaving a rectangle of cooling fins that's about 92mm by 170mm. The Hexus review states that "obviously" the cooler can be used passively or actively. Gosh, I wouldn't have thought of that.

The dimensions I "measured" were from a foto, so allow for some sloppage...

Oh, yes: the Coolermaster U.S. site sez the new cooler will "arrive" in March, so we're looking at one to three months to find one in a store.

Comparing with some other monster cooler out there then this method is probibly one of the smartest I've seen. It's easy to find some spot where to connect the cooler with a PSU or something else

A couple of corsair dominators there and a X6700 and you can have a fast and quiet system

Looks like the fans screw onto a mounting bracket that you can slide to wherever you want on top of the cooler. The screw holes on top of the cooler must be meant to secure the mounting bracket.

My Ultra-120 should be on its way, yet the GeminII looks mighty interesting. Hope we get some sneak (p)review soon!

Awesom-O! That's like the Godzilla of Coolers...

Felger Carbon · Post by **Felger Carbon** » Sat Mar 03, 2007 8:33 pm

GeminII is now available for purchase in the US of A, $49.99. Check either Google or Froogle and search "coolermaster GeminII".

I'm not sure the total cooling fin area is higher than my Dominator, which is currently awaiting delivery of some 14" fans (Yate Loon, Evergreen) for further testing. I've figured out how to whip the Dominator fan mounting problem (the Dominator has fan mounts for a 120mm square grid instead of the standard 125mm square grid for conventional 140mm fans).

The standard 20mm-thick stock fan for the Dominator is a really lousy fan.

The GeminII is now for sale at case-mod.com, where I've done business several times. They're in the San Jose CA area. If you buy *anything* from them, be sure to buy at least one $4.88 digital multimeter. An excellent 3.5 digit product, it comes with the 9V battery and very good test leads. The battery is already installed; the unit is ready for use out of the box.

Why buy more than one? Well, you might want to modify the test leads on one so they plug in just like a 3-pin fan connector. Makes monitoring the fan voltage a hands-off operation when used with a 3-pin Y connector, usually about a 75 cent item. And do you have any less-astute friends you want to help out for less than the price of a six-pack?

edit:

review added.

This is an extreme overclocker's review using 220CFM fans. The GeminII and Infinity (with push-pull fans) seemed to have the same performance - 2 fans in each case. But doesn't seem too relevant to SPCR!

ronrem · Post by **ronrem** » Thu Mar 08, 2007 8:09 pm

Gemini is available now at New Egg,about Ninja prices ($50) It's an option to the Aerocool Dominator if used with a giant side fan. I suppose counting fins is possible to see how Gemini/Dominator compare,but Gemini's 6 heatpipes should be some edge.

Review here. Some excellent pictures, particularly of 775 mounting. No K8 mount details. CPU cooling same as TT Big Typhoon, but also cools NB etc.

Post by **NeilBlanchard** » Fri Mar 09, 2007 5:42 am

Hello,

The three heatpipes on the AeroCool Dominator are each 8mm, or ~50 sq. mm, or 150 sq. mm total. The six heatpipes on the CoolMaster Gemini are (probably) 6mm, or ~28 sq. mm, or ~168 sq. mm. So, they are pretty close in heatpipe capacity, if my estimates are accurate.
