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

Better coolers add cost

Not much. I agree that it's a travesty. They should either do it right or make the mounting holes universal and let us all get our own coolers like what they do with CPUs.

They might have to do that eventually given how big these heatsinks are getting now.

Dude this card lays waste to a 7970

Good one lol

Good one lol

Down boy! Down!

Good one lol

Id love some 1200 core 7970 benchmarks to compare too :biggrin:

It ain't at 1200 anymore lol .

OT the GTX 670 is a pretty awesome card at $400.

Whatever you're at bro would be fine as well.

That's pretty amazing looking. I have a AC Twin Turbo II on my GTX 460 1GB and there's WAY more PCB to cover (and its not a long card)! The HSF looks fine sitting on it. Yours looks kind of...ungainly, but hey, the results speak for themselves.

Wow I didnt realize how small 670s are either. Are they all that small?

 

[Termie]

OP, can you measure the total length and height of the card with the cooler attached? Also, does it take two or three slots. I'm thinking about getting one because I don't like the idle noise on my reference 670.

BTW, thanks for posting your results.

The reference ones are after you take the stock HSF off (which makes it look like it has a longer PCB the way its fitted). Customs from Galaxy, Gigabyte and ASUS do have longer PCBs.

It takes 3 full slots.

Where are the overclocked results?

The reference GTX 670 PCB is 17.2cm in length (Link). With the reference cooler it is 24.1cm long. The last 6.9cm is just the plastic shroud the fan is mounted within. This is one of the reasons it makes that humming noise. Even at idle. It resonates because of the cheap plastic housing.

The Accelero Twin Turbo II is 21.7cm long However, when it is installed on the card, the total length is about 24cm pluss maybe a couple of millimeters. My reference Gigabyte GTX 570 (Which is dead now) was 26.7cm if I remember correctly. And it barely fitted in my CM Storm Scout case (Absolute max is 27cm in this case). Looking at my GTX 670 with the AC Twin Turbo installed, I still have a few cm left from the harddrive cage. Also, keep in mind, the ac twin turbo II will stick out out 3.3cm from the pcb towards the sidepanel, due to the coolers wideness (12.5cm)

It seems that a Turbo boost clock of 1257 + is very stable. Heaven Benchmark did not reach more than 49c degrees with the fans at only 43%. This was in 1920x1200, 4xAA Tesselation at Normal, DX11 and shaders at high. This cooler is just amazing.

It was just insane to see The Witcher 2 (Which is a very demanding game) hit only 46c with the fans running about 40%. This game really heated up my old GTX 570 and GTX 670 with the reference cooler, to insane levels, and with insane noise.

Also, OCCT 4.2.0 GPU test is probably the most demanding GPU tests I've tried. This test was simply to hard for both my old GTX 570 and GTX 670 with the reference coolers. They overheated, unless I adjusted the fans to insane levels. With the Twin Turbo II max out at about 57 -58c with the fans at only 53 - 55% (which is silent). But for all other tests and most demanding games, it seems I stay well below 50c.

The GTX 670 reference cooler is just the most terrible reference cooler I've ever seen or heard. GTX 570 had the same reference cooler as the GTX 580 did (And was of some quality), but the reference 670 cooler is a pathetic excuse for a cooler, and shame on Nvidia for making such a crappy cooler.

A google search on GTX 670 reference noise says it all.

Awesome info. So to confirm, it's actually no longer than the reference cooler? That's amazing.

Agreed.

Now I just have to decide if I buy this for $46 from Amazon or stepup to a reference 680 for $125 shipped. The 670 will reach similar speeds at lower noise, the 680 will be much easier to upgrade to and will be guaranteed to work in SLI down the road. The AC may block the bottom slot.

OP or others, any suggestions.

I got burned (literally) by the reference cooler on my 7850 as well, and I also went with the Twin Turbo II. I'm very happy with it and had results nearly identical to yours.

I'm never buying a reference card again unless I can re-use my Twin Turbo II on it.

Yes, I can confirm it's a tiny bit over 24cm with the AC Twin Turbo II installed. About the same length as the card with the reference cooler mounted.

I can tell you right now that the AC Twin Turbo II is a 3 slot cooler. When installed in my ASUS P8P67 PRO 3.0 the second PCI-E x16 slot is still free (as far as I can see), but barely. Running SLI with these coolers in a motherboard having normal spacing between the PCI-E x16 slots will be unpractical. The upper card will get little to no airflow.

I have no plans going SLI in the future, so for me it won't be an issue.

The Twin Turbo II is very versatile, and can be used with all kinds of newer and older cards. However, you will either need some thermal tape or some new glue/cooling paste mix to attach the heatsinks, if reusing.

I'm sure even the Accelero Mono PLUS would do a great job cooling the GTX 670 reference. It has a 120mm fan and 200w cooling power. Probably would look better on the GTX 670 VS the Twin Turbo II, as it is only 14cm long

Some results from the Mono PLUS (in German, but the graphs show the results)

I was looking at the GTX 670 (reference) and the AC Mono. I think they might look pretty good together give the short length of both. That single 120mm fan ought to cool it very well.

Looks weirder with a waterblock

Sweet! Someday I'd like to go back to custom H2O. BTW, love your sig :thumbsup:

Is the cooler reversible to the backside of the card? Or does it interfere with something else (perhaps the hsf) there?

Do you mean like this one:

If so, no it is not. btw, it's the thermalright HR03 PLUS in that picture. popular for 8800GTX and 8800 Ultra in it's days
