Arctic Cooling Accelero Twin Turbo II Cooler for GTX670 - Page 8

post #71 of 83
Just installed the Twin Turbo II on my MSI GTX 670 O/C (small PCB version), and aside from the nerve wrecking installation of the damn thing (the thermal glue is indeed terrible, but eventually works) it cools like a charm (around 29C idle, and never breaks 51C on full load on a conservative fan curve).

I do notice some bending of the PCB due to the weight, but hope to be able to solve this with a backblate or a bracket of some type.

All in all I'm very very happy with it.

Hi.

I did the same and to prevent bending I've done 2 things:

- 1 metal plate I screwed on the edge of the PCB (using existing holes), of course I used rubber in order to insulate the plate and so to avoid electrical troubles

- 1 plastic thing (sorry I don't have an other word ! biggrin.gif ) I put between the Power Supply (bottom of my case) and the Accelero to sustain the cooler and its weight. I also put rubber to avoid "scracth" (plastic can make little sharp marks).


For the 2nd option you can use a piece of wood, cut at the needed length.

I just ordered a Twin Turbo II with some 3m thermal tape for my Gigabyte GTX 670. The Windforce 3x cools well enough, but I find the fan speeds I need to keep the temps where I want them (~60c requires 50-55% fan speed) are high enough that noise becomes an issue. Heat is an issue in my office. While gaming I normally see temps around 24-25c, and I just don't think the Windforce 3x is up to the task of cooling effectively and quietly at those ranges.
I apologize for asking if this has already been covered, but compared to the Windforce 3X cooler what kind of temperature drop can I expect (ballpark figure) with the TT II? For those of you with the TT II, is 100% fan speed noticably loud?

I put an Accelero Mono Plus on mine because on the 4gb card, the twin requires more modding of the spacers than I wanted to do. The Mono doesnt look as nice but cools very well. I run Skyrim at 2560x1600. The GPU temps hover in the 51 degree range and I've never heard the fan.

As I did not own a Windforce 3X cooler, I won't be able to answer.

What I can tell you is that at 9 Volts, the Accelero noise is very likely to the one you can hear from a fan located in a front of a case (to refresh HD).
And I am dealing with quiet fan for cases when saying that.

But remember, the Accelero will be IN the case, so the noise will be lower.

In the Accelero package you will find a "voltage reductor" (4 pins Molex to put 7 volts instead of 12 volts), if you are very upset with noise you could try... but, unless you've got a full "mesh case", I don't think that even at 12 Volts (full speed) you're going to really hear the noise.

At full speed and with unigine engine, I am nearly at 50°C with the Accelero.
[Of course it will depend of your case, its fans and the surrounding temperature.]

That's good to know about the voltage. My case is pretty well setup for positive pressure (HAF 932 w/extra fans and a fan controller) temps inside the case sit within 1-2c of ambient. I'm not after dead silence, but I'm trying to hit that balance of excellent cooling to noise ratio. I think the TT II will get me there.

I think it will do perfectly the job.

Just one thing, there is an old version of the Accelero: no tapes for insulation and thermal adhesive paste in 2 parts (you need to mix for few minutes, and then to wait hours ...).

In the new bundle, they added tapes (to cut) for insulation (to avoid electrical contact between components with spreaders on memory/ VRAM for example) and a new adhesive thermal paste: 60 minutes to fix (that's what they say... biggrin.gif ).

Hope it will give you satisfaction. thumb.gif

If you're concerned about noise from the ATTII fans you can always remove the fan shroud (comes off easy) and zip tie a couple spare 120mm fans on it.

I have a rather silent system and even tho the ATTII fans weren't that loud to begin with I could still hear the motor noise in a quiet environment - if there's any bit of ambient noise the fan noise would be drowned out.

I replaced the fans with a GentleTyphoon 1850rpm and a low noise 80mm. The combined noise of those 2 fans was lower than the ATTII fans and temps improved from uniengine load hi of 55C ( dual ATTII fans) to 50C overclocked (120mm+80mm fan).

Again, it's not really necessary to do that but if you have a quiet system it's an option.

I was thinking about getting a cooler for my GTX 670 and I heard some pretty good stuff about this Accelero TTII, which have been confirmed here. I've pretty much made up my mind on buying it, but do I have to be concerned with the bending effect?
post #80 of 83
When I installed by Twin Turbo II on my 680 some months ago, I didn't have any thermal paste handy so I just used the pre-applied, and it's always kind of bugged me a bit.

So I was wondering if anyone has changed from the pre-applied to other compound, did you get any notable temperature reduction or is the pre-applied stuff ok?
