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

[2is]

Yep, that's what I meant.

The card got bent pretty bad, due to the weight of the AC Twin Turbo II and nothing to stiffen the pcb so I found a solution to bend the card back and holding it in place

btw: That PCI bracket holding the card up does not even show when the sidepanel is installed on my CM Storm Scout, due to the sidepanel having one 120mm red led fan covering that area. Also the 120mm fan in the sidepanel is feeding the two Twin Turbo fans directly with fresh air. Helping even more on the already great temps.

Ah. The pencil mod.

Yeah, you could put it that way

I tried Diablo III for a few minutes a little while ago.. GPU temp at 30c :wub: I know it's not a very demanding game, but this cooler is just totally insane for this little card :thumbsup: I've seen idle temps as low as 24c

How are the Vram temps. The one problem I always noticed with the Accellero products is the passive heatsinks don't cool the vram as well.

Have no monitoring on the RAM chips but from my experience these types of coolers (HR03 Plus on a 8800GTX. Much better temps across the board VS stock cooler! 8800GTX had monitoring for many different components. And temps got much, much better!) should cool the RAM much better VS enclosed stock coolers. Due to the fans blowing air down on the PCB and cooling the RAM sinks/chips.

Also, my GTX 670 has half of it's RAM chips located on the backside. These had no RAM sinks with the stock cooler, so they are better cooled now, in any case.

 

[The_Golden_Man]

Actually, I don't think there would be a problem running two of these reference cards in SLI with the AC Twin Turbo II, since the cooler extends so far out from the card, both in length and sideways, the upper card would get plenty of air through the heatsink. Also, since it has so great temps with this card already, I really see no reason why it should not work.

Just got my Twin Turbo II installed on my Evga 670 reference, and yeah, its like night and day. No more annoying fan hum/grind sound, and load temps dropped...

Almost 30 degrees. Was topping out a bit over 80, now runs in the low 50s. Clock is now boosting to 1110 at stock as it "should."

Seriously poor stock cooling for such an otherwise good card imo.

I considered the Mono version, but everywhere I looked the Twin Turbo II was the same price (got it for $38 from Ncix).

Time to do some overclocking later.

Congratz! :thumbsup: You have any coil whine from your reference card?

Would love if you took some pictures too

Yes, very minor "humming" noise only audible with the case door off (Antec Solo II) and my ear near the card (first noticed it last night because the AC TT II is so quiet!). Maybe its just my setup, but I'm convinced you are almost guaranteed some small amount of coil whine from this generation of video cards. Had similar experience with Sapphire 7950 and 7850. YMMV.

That looks awesome!

I wonder how much it will cost.

Says $180 - too much! Nice idea though...

 

[birthdaymonkey]

I get some coil whine on my Asus 670 DCII, and the card maxes out in the mid-70s with very conservative default fan profiles. I can barely hear it over my 7v-modded Nexus case fans.

It's not quite as good as the TTII (had one of those on my previous card), but if you're looking for a 670 that doesn't require an aftermarket cooler, the DCII seems a good bet.

The only thing that annoys me about this card is the driver bug that seems to be causing a lot of stuttering with vsync on (which is always the case for me).

Price isn't bad for water cooled when you consider it includes EVERYTHING for a true water cooled card. If you already have a water cooling system for your cpu, a water block runs @ $130.00 and has the advantage of covering both the gpu, vram and memory. However, this system includes water cooling for the gpu, heatsinks for all of the memory and vram AND an Active fan shroud system to cool it all. Price all of that seperately and the price isn't that far off.

I fail to see the benefit with this watercooler. With the Twin Turbo II I get 45c degrees in the most demanding games (custom fan profile), overclocked and silent. Cannot hear the fans over my case fans.

Even if this watercooler did bring the GPU down to 35c degrees, so what? There are no possibilities for upping GPU volts anyway. And if so, the Twin Turbo II would handle that without a problem.

Also, it's much more expensice VS the Twin Turbo II.

With regards to watercooling I can only see the benefit if a system have some custom watercooling on the CPU too, and add a block who covered GPU, Vram and vrm.

The EVGA FTW 670 I just got has regular 680 length PCB. However, i wouldn't mind a shorter 670 without an overhanging heatsink for HTPC use. Anybody know of an aftermarket cooler that will make a reference 670 shorter? A downclocked 670 with a smaller heatsink and fan, plus ITX case. Couple it with a low power Iv-B and ITX gaming wouldn't be far behind regular sized rigs. Especially since HTPC gaming would be at 1080p, where the 600 series seems to really shine.

Yeah it was a close call for me, decided on EVGA + TTII for a bit of extra $$. Wanted the EVGA warranty/service and if the TTII fans go bad you can buy a replacement for $7 from the AC website.

off topic: Now if I can only find a pwm fan that doesn't "tick" for my cpu cooler (both Scythe's I have bought have had this...sigh). Trying out the AC pwm fan tonight. I don't mind noise coming from my computer as long as its a pleasant "whooshing" sound.

I've never had much luck with PWM fans. I think that's caused to a certain extent by the fact they're made to run at high rpm and require some kind of extra material for this reason.

I'd recommend trying a fixed-speed fan, and either using the motherboard or an external controller to set the fan speed. I use a Scythe Kama Flow 2, and it's really, really quiet, with just that "whoosh" you're looking for. Goes up to 1400rpm, but with a manual controller, I usually set it around 1100-1200rpm, and just turn the knob (which is attached to the back of my case) if I'm running a heavy load on the CPU.

As an aside, that's why I'm so ticked off at my EVGA GTX670. I pay extra for good case fans ($60 worth in my case right now), so getting the cheap fan on this card has really stung. I'm waiting on the GTX680 stepup from EVGA now. And yes, even with all this (and an RMA on my first 670), I'm very glad I went EVGA. Their service is superb.

Watercooling doesn't take up 3 slots like your cooler

 

[guskline]

My GTX 680 uses the reference cooler and the cpu is cooled by the Corsair H60 with a p/p fan system. If I was to change the GPU cooling I would go to a complete water cooling system to handle both the cpu and gpu. Running SLI would not cause a problem with either my present setup (reference cooler) or with a water cooling block.

How could you run SLI with these Accelero coolers?

Yeah if the AC pwm doesn't meet my expectations I'll just go fixed speed with no "ticking". As you know, the quality of the noise is just as important as the quantity .

I was refering to this one http://www.arctic.ac/en/p/cooling/vga/569/accelero-hybrid.html?c=2182

Looks like it is a little over 2 slots

Nothing I can hear over regular case noise. My case is hardly "quiet" though.

I'll turn my other fans down and open the side panel next time I game to check.
