Update

[Okda]

so heatsinks with fans mounted parallel to the mobo is better for cooling the components even if ur cpu will be hotter by 2~3C

thanks for the review

[roadie]

So it appears for low RPM fan use, the Ultra 120 Extreme and the Gemini are neck and neck in terms of CPU temp?

[zanzabar]

for reference, cool master and thermal take have been the same company for 6months+ now, and cool masters is the name sake for cooling products

what ???

[PhilDoc]

First, it would be nice to hear what your conclusions are and second why not use 2 fans on the Ultra-120?

[lowfat]

where do you get this? Pretty sure that is false.

[Grafton]

never heard anything like that on the cooler master forums i bet it is false as all get out

[Spawne32]

what?

[Start]

The results aren't that suprising, two 120mm fans blowing to the chipsets, mosfet, and memory of course will cool a lot of stuff down.

[rbsmontemor]

Test with a quadcore please

i have all the Q6600 results, only problem is, i cant get cooler master to respond with a gemini 2 sample :/ im gona have to order one soon.

Looking forward to your results

I really don't wanna believe that I really don't wanna believe that I really don't wanna believe that...
Proof please?

You dont have to, theres no proof of that, i doubt its true, and i will contact Thermalright directly about the matter if he can amount any truth to it. I think he may be mistaken with Thermaltake, but even then i cant say that it is true. I think hes completely mixed up and confused.

good review

[it_burns_when_i_pee]

remember it is 1 fan vs 2 fans. if thats anything to go by the ultra is better because it keeps up with just one fan!

but depending on your case layout, the gemini could be a good choice! considering the downward force of air will contribute to mobo heatsink cooling or heatinking up (if the cpu is very hot). if your psu is directly above with a fan then hot air will be blown down into the direction of air being exhausted out through the psu.

to get more "real world" results you should test both in a case because of restricive flow / drag a case presents. the gemini could suffer alot if the distance between the side of your case and fans is only a few inches - it will greatly effect the fans CFM output. try putting your hands either side of your fan and move it closer to reduce drag & you will see what i mean

[Pntgrd]

I am thinking that for almost the same performance vs the Ultra 120 the added benefit of chipset cooling would make this a good choice. In my case there is almost no way to get air to the PMW area other than what goes from the Ultra 120 to the rear exhaust fan. I am using a small chipset fan but what good it is doing is debatable. The loss of the 2 top fans in the side of my Stacker with the 120 is also a negative. With the Gemini and the addition of the top 2 fans in the case it seems to me that I really need to try the Gemini. I just may be one of those cases where the Gemini may be a better choice. I also think of the way the Uptra is so top heavy as a negative.

I may have missed it in the review but how was the base of the Gemini? Will it need to be lapped?

The initial results of the gemini 2, if i remember correctly, when it was first released, werent all that impressive, not sure why. Judging by the pictures it looks to be a standard mass production style base, probably has some minor imperfections but an over all good quality.

[PhilDoc]

I think its all going to depend on what you want and need. The Ultra is going to be the better cpu cooler. As I mentioned above the test was done with only one fan on the Ultra. Just from Vapor's review, the Ultra is going to drop around 4-5C under load with the second fan. If you go with that the Ultra will be 4-5C better than the Gemini.

As far as the rest of the temps are concerned, the ony one that I think would make much difference is the memory temps. MB temp would rarely make a differnce in overclock. Perhaps you could get lower video cards temps because of it and help that way.

Memory temps do make a difference however, but for my money, I'll just hang a 120mm fan blowing on the memory. You could, though, gain a few mhz on the memory using the Gemini.

As far as overall airflow affecting overclock much, I'll let you know in a week or so. I'll be going from a wavemaster, very poor, to a stacker 830. I will probably gain a slight amount from having cleaner air getting to the Ultra, but mostly I'll gain some extra room to work with, which will be helpful in itself.

Anyway, for me I'll go with the better cpu cooler and find another way to cool the rest of the electronics.

I also thought I would gain some room with the Stacker. When I first got the Ultra in the mail I knew I was going to have a problem with my old Antec P160. It would fit in there but it would be like building a wall it was that close. So I picked up the Stacker to gain some room for the Ultra. Unfortunately, you lose the top rear fan in the door due to the Ultra. That is the fan that might of gotten some air to the PMW area of my IP35 Pro. IF you use a 120x38 fan you will also lose the top front fan in the door.
I tried a push/pull setup on my Ultra wit 2 Antec TriCools on high but found that using my SanAce with a 120x25 spacer in push on high my temps were the same.
I still am intrigued by this to see if I can get better PMW temps while maintaining my cpu temps with the Gemini vs the Ultra. SVC has the Gemini on sale and with a rebate to boot. Final cost would 14.95 + shipping. It is mighty tempting. Then again maybe I should just bite the bullet and go back to water.

Thanks, that's good infor to know. Sounds like I'll loose both of the top fans, which means I'll probably have to figure out something for the memory. Bummer, oh well, at least I should be able to close my case, lol

Wow, that's cheap. For that kind of money its certainly worth a try.

[Vapor]

That's either the best GeminII or the worst TRUE I've seen....not sure which.

The GeminII has a major advantage with unrestricted ancillary airflow toward the board, but for CPU cooling, something's awry. :-/

[it_burns_when_i_pee]

the weight of the ultra 120 is deffinately a concern. it sags alot in a tower

i counteracted this by using a zip tie looping around the top ends of the heatpipes to the powersupply. works a treat, doest sag at all now

I haven't noticed that yet, but haven't really been looking either. Thanks for the heads up, I'll watch for that.
