Calling anyone who owns one of these for their opinion. Thats it really!

Also, to mount the thing to a mobo, do you basically turn the heatsink upside down on a table, turn the mobo upside down and place it down onto the heatsink and tighten the nuts on the underside?
 
Easily the most pointless cooler yet produced... almost twice the size of the Tuniq/Ultra-120 and doesn't cool anywhere near as good.

It's a gimmick. :(

Thats not what I asked but thank you for your opinion :)

Unless you own(ed) one?

I realise that wasn't what you asked, but as you asked the question I was presuming that maybe you were intending to buy one, therefore offering sound advice on its worthiness as a purchase. So sorry if that bothered you. :)

Can you substantiate what you are saying? Ive read some very good reviews, and a few otherwise too. I cant see how using a cooler like this on a passily cooled mobo where ram/chipset/vrm will be cooled too can be a bad thing. When I had a Big Typhoon it was a great heatsink, this is just that times two? Im not looking to trump my Tuniq, I just think some extra cooling over the ram/chipset/vrms could be a good thing. Also looking for something to do over the long weekend :D

If you genuinely think that then there's nothing I can say that'll change your mind as it's only my personal opinion but I think you can get far better and more practical solutions for the money. Have fun with it. :)

Anandtech is the only review I have read that says its rubbish. I havent made up my mind, Im not posting just to get the answer Iwant to make myself feel better about a possible purchase, I would just like substantiated and reasonable arguements to why someone says its rubbish. Even on anandtechs review @ 3.8ghz it doesnt go over 60C with any fan they throw at it, and on the pic showing system temps the mobo is @ 35C (I assume the pic was taken when using the geminii). Currently my mobo temps are 45C-47C which, although not hot could do no harm with dropping 5C or so.

Maybe I should just get one and spend the weekend testing it against my Tuniq and I can report back if anyone cares? At least it will give me something to do :D

Good article on fitting here:
http://www.hi-techreviews.com/Joomla/content/view/3398/27/1/2/
and another here: http://www.hardwarelogic.com/news/62/ARTICLE/1355/2007-03-08.html

Incidently I am using one have upgraded from an artic freezer so I'm happy lol

When you say you are happy, did you notice a substantial improvement over the freezer? Did you happen to notice mobo temps before/after fitting the Geminii? Your feeback is greatly appreciated :)

Also those reviews I read but maybe I missed where it actually gave the info on fitting. It tells how to fit, but I am just trying to work out if what it means is: Geminii on table, mobo turned upside down and put down intop of the geminii? Is it a difficult cooler to fit?

I care. I'd be very interested. And more worthwhile than spending the money on food. ;)

Alrighty then. Ill do that then! Ill be testing the cooler with 2 Sharkoon Silent Eagle 1000 fans vs the Tuniq with a Sharkoon Eagle 2000 fan, unless you would prefer a direct comparison and Ill swap out the fan in the Tuniq. I just thought 1 fan vs 2 fans compensates for the lower rpm on the fans going on the GeminII vs the rpm of the single fan in the Tuniq (sharkoon 1000 (1000rpm) vs sharkoon 2000 (2000rpm). Thoughts? Id like to make the results as useful as possible :)
 
I have only slightly clocked my e6400 but at e6600 speeds temperature is 30 and my system is 27. The bios reports temperatures lower than this, but the above temperature readings are from the thermal probes that came with my Lexa case. I think it is quite easy to fit: depending on the way you orientate the heatsink make sure you have your ram in first. All you have to do is bolt the cooler to the board prior to installing the motherboard in to its case.I only finger tightent the nuts as there was no point in causing any damage using the adapter. I am using a ds3p which is sli so it gave me the option of turning the heatsink towards one of the pci slots if I so wished. I will never use an artic freezer 7 again though.

Ideally you should test with the same fans, as then you're only testing the heatsinks, not the fans.

What I would like to see is the Temperature achieved by each after 10 minutes running the 100% load test inside TAT.

Given that you have to pull the motherboard I would say it's just as valid to test the two systems on bench as that massively reduces the chances of you damaging anything putting them back in. Plus, sod's law dictates that the one you will want to keep on your system is the one you tested first, so you'd only have to pull it again a third time, most likely.

Big test here, it doesn't beat the the old Scythe Infinity... http://www.xtremesystems.org/forums/showthread.php?t=132996&highlight=gemini

Shame he couldn't get a Tuniq in there to test. The Noctua doesn't do great... quite surprised by that.

It doesnt beat the Infinity, but it gives the exact same temps. Is that a bad thing? One test he didnt do was to show chipset/vrm temps using the coolers. I think you missed my point where I said I wasnt planning to best my Tuniq but the added cooling for ram/chipset/vrm's seemed like a decent idea. Anyway Ill have one for the weekend and will do some testing.

Edit: Actually opening my eyes and looking at the screenshots I can see that the GemimII Chipset temps are 11C lower than the Infinity and other coolers. Am I stupid in thinking thats a good thing?

Just installed the Coolermaster Geminii. I am using 2 x Scythe s-flex 1600rpm fans and another two as case fans all running at full speed. Chip is a Core2Duo. Ultimately it is a dissapointment. I find the top down cooling idea sound and it has worked in lowering the MCP temp (680i) to 40c idle from 60c idle (also turning the nvidia chipset fan around so it blows out, onto the graphics card. Graphics card temp increased from 40c to 45c. From that I will take taht it is doing an excellent job of cooling other components under its shadow.

The mounting to the board is really secure, wish Scythe would use screw down fittings.

Geminii flaws:
The finned area was clearly designed for two 92mm fans. Perhaps the performance wasn't up to scratch and they decided to bodge two 120mm fans onto it.
You end up with two massive deadspots over the shallow fins and about 30% of the bladed area directing air onto the mainboard not through the fins. It will probably work as effectively with a shroud and 1 120mm fan. (I'll be testing that theory).
Sizewise it is bloody enormous with two fans on - on my standard midi case there is maybe 3mm clearance between the coolerfans and the casefans.

Heatpipes:
I was reading yesterday in an xbit labs review of the Scythe Andy that the best orientation for that cooler was with the heatpipes facing the bottom of the case, with the second best position being to the right or left and the least favourable position being at the top of the case.
On the geminii, there is really no other choice but to use the orientation where the heatpipes are at the top of the case. I ran Orthos and placed me case on its side, so the mainboard was now flat, like in a desktop case. Within five minutes my CPU temp dropped 6c - thats enough for my CPU to handle the Orthos blend test @ 3.73Ghz and keep the Cpu temp @ 65-67c load.

Overclocking: Reviews all use there own methods so it is not easy to compare their temps with you own. So if I go for the best? CPU stability test of Orthos Small FTT then my max. overclock is 3.66GHz @ 1.48v(bios)
SuperPi will work at 4.0GHz, idle temps of 51c though!


Would not recommend this cooler! much better price/performance/noise coolers out there!

nice review there frank , although i am stil considering it .
can you please tell me its height with the fans attatched please frank ?

What was the reason for not being able to mount it with the heatpipes the other way round? Was it the Northbridge heatsink getting in the way?

Don't know the height with fans. My case is 210 mm wide(outside) and there was about 75mm from the top of the fan to the outside of the case - I was thinking of putting a hole in the side panel and ducing air in to the cooler.

The cooler would fit in the optimal position outside the case, clearance with the northbridge heatsink wasn't an issue, but it has an assymmetrical design and so was either level with the edge of the board or had a slight overhang, either way it interfered with the rear mounted case fan and was a non-runner.
