ARCTIC Accelero Twin Turbo II installed on MSI GTX 670 reference card

[The_Golden_Man]

The GTX 670 reference cooler is just terrible. The plastic housing the fan is installed in makes a terrible resonance sound. Even at idle with the fan at it's minimum of 30% this annoying sound could be heard from the next room.

Also the heatsink itself is way to small.

So now I've bought myself a ARCTIC Accelero Twin Turbo II :biggrin: This cooler has just been approved (Same cooler as before, just checked to be compatible) to be compatible with GTX 670 and GTX 680 reference cards.

So today I installed it, and wow!

In the Witcher 2 the reference cooler hit almost 80c with a terrible noise from the fan speeding up. The ARCTIC Accelero Twin Turbo II is hitting 46C degrees with the fans at only 40% :biggrin: And totally silent! Cannot hear the fans over my case fans!

Also with the latest OCCT, which stresses the graphics card to it's limits, it did not hit 60c (58c - 59c) with the fans at 55 -60%. The reference cooler overheated in this test. And the test aborted itself when it hit 85c. I had to run the fan near it's max 80% in order to run the test. And the noise was terrible!

Edit: Idle GPU temp is sitting at just 25c

Anyway, very happy with the ARCTIC Accelero Twin Turbo II, can confirm it works with the GTX 670 reference and warmly recomment it to anyone!

A few pictures:

The card got bent down pretty badly due to the weight of the cooler and nothing to stiffen the pcb so I found a solution

Now thats funny looking

I'm shocked at how small the GTX 670s are. They look even smaller than the 7850 PCB.

OP you should see a nice drop in temps. I hope you wrote them down from the reference cooler.

Aww that 670 PCB is so tiny. But I'm glad it works out for you. I'm planning on reference EVGA 670 + Twin Turbo II as my next upgrade.

The temp drop is totally sick. As I've said, in the Witcher 2 with all maxed (Only uber sampling disabled) the reference cooler hit almost 80c at really high fan speeds and 1137MHz - 1150MHz Turbo boost. The noise from the reference cooler is sick.

With the ARCTIC Accelero Twin Turbo II I hit 46c in the same game (Turbo Boost at 1267MHz! Overclocked it), and with the fans at only 40% + ! Totally silent!

Basically you could OC the card by a sick amount and still retain good temps and total silence at load. OC'ing would become dependent on VRM cooling, really.

As you can see, I left out two ram sinks due to the mounting bracket covering half the ram chips.

Looks weirder with a waterblock

I cannot get over how small this card is... Almost like a soundcard or a very cheap graphics card.. This small, yet beating a Radeon 7970 in many tests, and even besting GTX 680 in a few cases, due to Turbo boost clock varying from different cards... And all this coming from this tiny little card...

Dude this card lays waste to a 7970

Nah, I find it looks like a red headed stepchild with the Twin Turbo on there. The waterblocks look bad-a. I'll probably go with water if/when I ever go SLI/Crossfire again.

Yeah, I know :biggrin: It's almost unreal :awe:

Try telling that to a 7970 owner who overpayed :whiste: :twisted:

Who said we were talking stock clocks?

 

[tviceman]

What frequencies are you running the card at on the core and memory with the new heatsink and fan?

Turbo boost have been up to 1267MHz and seems stable. Much over this, and I get artifacts. Memory runs at +400MHz in afterburner. I assume that accounts for about 6800MHz mem clock. at + 500MHz I had to take the GPU clock down.

But the temps with this cooler is just insane. And it's very, very silent

Edit: Will probably try take the memclock further down to see if I can get an even higher Turbo Boost.

It might be better to run the memory as high as it will go, and adjust the core from there. I do believe that is the best overclocking strategy for the gtx680, at least.

Memory doesn't scale at all over 6400

I wonder how wierd the reference GTX 670 would look with the Accelero xtreme III installed :hmm: 28.8cm long

Right...because u cant overclock a 7970...

 

[SickBeast]

Look, the 670 680 and 7970 are all equal. Just buy whatever is cheapest.

LETS GET BACK ON TOPIC

that card looks really really funny

 

[BD231]

So anyone wanna chime in on why $400-$500 dollar premium cards come with utter *SH T* stock coolers? He just cut his temps in half for $40 bucks, WTF!?

Better coolers add cost
