New cooler from Artic-Cooling: Accelero TWIN TURBO

thejamppa · Post by **thejamppa** » Tue Aug 05, 2008 2:53 pm

I think that is not arctic coolings... First fan seems to 80x80x25mm and Arctic cooling had habbit to use 80x80x15/10mm fans in intgrated systems. That cooler was first time in MSI's 9600 GT's Hybrid Freezer edition and I am hoping we get soon supply with MSI's HD 4850 with that cooler. Seems to be very effective and probably enough quiet for my game rig.

That cooler does remind me of GF 7900 GTX... It still has one the best reference cooler designs... ever...

From what I've heard, it has been delayed until sept for us here in the USA

Somebody already has this cooler?

I wonder how many, and which ram & VRM heatsinks come with this cooler. And what the quality of the adhesive of this sinks will be. The sinks of the Accelero S1 don't stick that good, I read.

I recently purchased a HD4870 and a Twin Turbo. At first things looked really good. It was easy to install and build quality was decent for a sink that's rather low cost. Then I looked at it closer.

First I noticed that the sink wasn't properly aligned. The sink wasn't flush on the GPU die and that was because the sink's heatpipes were propped against the lowest RAM sink.

Then I went to AC's homepage I noticed that they had posted some information on how to improve the compatibility of the sink. This stated that the bottom RAM sink had to be moved upwards a bit to clear the pipe, which pretty much leaves the RAM bare, with only the hot-as-hell heatpipe over it to "cool" it

. Furthermore their recommended sink configuration shows that the three bottom VRs should be covered by two VR sinks so that they meet over the middle one. This simply does not work as there is not enough surface to fasten the sink properly. The sink would fall of even at the slightest touch. Using a single sink fastened fine however, I don't know if this offers sufficient cooling.

After two failed attempts at mounting the sink properly and a considerable amount of curse words, I decided to bail out and installed the original sink back on and left the Twin Turbo in the cupboard to wait for a better solution to the compatiblity problems. So one may ask "Is the sink REALLY HD4870 compatible?".

Seems te be the same problem as with the Accelero S1, Like in this picture:

To achieve a good adhesiveness between sinks and chip's, it is very important to clean the chip's very good after removing the stock cooler and before installing the ram/vrm sinks. But seems to be the same poor adhesive as with the S1 cooler.

Do you have pictures from the stated problems, as well from the collection (types, and amount) of RAM/VRM sinks that are included in the package?

What you can do (works on the S1) is to press with you thumb on the heat pipe that interfers with the ram heatsinks and bend it towards the cooler and away from the graphics card. You can bend it enough to clear the ram heatsinks.

PaulzY · Post by **PaulzY** » Thu Aug 21, 2008 8:44 am

some problems with installation (outlined on their page)

can hardly cover this memory module as heatpipe gets in the way, if you had one that was only about 5min tall it should be okay.

It seems to bend away so I had no problem with the voltage regulators, I could have installed them normally.

but then it crams against my sata port on my ex38-ds4 but still fits

stock cooling was ~80 idle and a few more for load around 84 degrees and fairly quiet stock and wooshy when playing games.

with the twin turbo fan module plugged into the cards board it starts then stops by the time your in windows and will creep up to 80 degree till it comes on, and only one seems to start or keep going and will go down to 75 idle. as per there troubleshoot page, they tell you to use rivatuner to start fan earlier, except 4870 is not supported (morons), so I'm using the molex adaptor, you have a choice of 7v and 12v. 12v is noisy probably more than stock when playing, 7v is too noisy also :/

its 33 degrees idle for 12v and 40 degrees idle at 7v (case door on) and ~46 for load

Has anyone tried using a thermal epoxy (e.g. Arctic Silver Adhesive) with these sinks? I wonder if it's effective.

thejamppa · Post by **thejamppa** » Thu Aug 21, 2008 10:23 am

I think best way is to change thermal interfearance material and as for problem with heat pipe: You could bend the ram sinks wings slightly, making central groove wider, allow heatpipe go there without interfearance.

I just spent an hour cleaning that goo off from S1's ram sinks and installed new doublesided thermaltape (3M's which I cut into suitable pieces) for tomorrows installation.

Yes, AS Adhessive is very effective. I've used it to attach older heatsinks in very old VGA cards and such. Its bit expensive but that thing will keep things attached while not hindering thermal conductivity like if you put regular crazy glue on ramsinks with adhessive..

disco stu · Post by **disco stu** » Thu Aug 21, 2008 10:54 pm

C'mon people can sombody please answer these questions?

1) How many VRM sinks (and which different sizes) come with the cooler?

2) What is the minimum voltage or minimum PWM duty cycle percentage (from graphic card itself) needed for the fans of the twin turbo to spin up?

I have here Arctic Silver Thermal Adhesive. When adhesiveness should not seem acceptable, I will remove thermal tap and use the A.S.T.A. Still figuring out how to use it in combination with AS5 so the sinks can be removed in future.

Once I buy 4850...

1) Accelero will come two PMW heatsinks, suitable for Ati X1950 pro, Ati X1800 and X1900 series. FOr 8800 GT(s) and HD 38x0 and HD 48x0 do not need VRM heatsinks according Arctic. If you want to have such things, then you have to buy separate heatsinks for ram package and use them to cool down the VRM chips.

Has anyone tried using one of these with a side fan?
As the heatsink isn't wider than the card it should be possible to have a 12cm fan blowing air at it from the side. There's quite a few cases that have sidefans or fanducts (i.e. lian-li) - sidefans can't be used with most heatsinks on the market as almost all of them are too wide, but this one would be a prime candidate (just remove the fan module).
I would be very interested in hearing what temps can be achieved that way - ideally you could then cool the card with just a 12cm@5v fan - I'd also leave at least 1 more slot open than the old S1/2 w/12cm fan method and be easier to install to boot.

falcon26 · Post by **falcon26** » Sat Aug 23, 2008 9:19 pm

Does this cooler require 2 fans headers for each fan? And when the heck is it coming out? I thought it was July but I guess not...

thejamppa · Post by **thejamppa** » Sun Aug 24, 2008 12:14 am

Appareantly it has 4-pin fan header for the PCB and 3-pin motherboard header, but like Turbo Module, one fan header powers both fans.

PaulzY · Post by **PaulzY** » Mon Aug 25, 2008 6:36 am

I switched the pins around and tried to run fans at 5v, but it wouldn't start

Answer by Arctic-Cooling:

Dear Sir,

the Accelero Twin Turbo comes along with 8 Ram-heatsinks, and 4 double-VR-heatsinks.
Regarding the start-voltage I'm sorry, but I can't provide you any information about that at this moment.

Best regards
Arctic Cooling Support

darn I was thinking S1 and not Twin turbo. My mistake. Sorry.

no, it's some other chinese brand (i don't recall which).

anyway, this thread at tom's hardware has some temps if you're interested how this performs. plenty of pictures too.

with new version of rivatuner 2.10 I can slow fan down to 35% and not hear it over the whirl of the WD 640GB, and rise it up to 50% for when gaming. Now I really want one of the new VRaptors for a sys drive in a Scythe Quiet Drive.

MoJo · Post by **MoJo** » Mon Sep 01, 2008 10:19 am

Sorry, just to re-cap, the Twin Turbo does not fit the 4870 properly, but what about the S1? It's listed as compatible and contrary to some reports seems to work okay on the 4870 (with active cooling), if you make a small mod to one of the RAM sinks...

nici · Post by **nici** » Mon Sep 01, 2008 10:40 am

I have the S1 rev.2 on my 4870, and im using the stock VRM / memory cooling plate and it fits fine. I removed the red aluminium plate from the stock cooler, it's just a few screws, and then mounted just that on the card and the S1 on top of that. Works well but definately needs a fan on the heatsink or nearby.

Thanks nici, I think I might give it a try then.

So how's it going PaulzY?

I'm considering a 4870 + Twin turbo.
Have you had any problems with the setup?
Is the uncovered ram a problem?

PaulzY · Post by **PaulzY** » Wed Sep 03, 2008 9:07 pm

card is awesome, since I haven't really gamed on pc since AGP video card days

Uncovered ram hasn't posed a problem for me, one of the heatsinks is slightly touching it so must be doing okay to transfer the heat maby to the other ones touching it if you look at my pics above. If you don't have fans plugged into molex (which is always just the one speed and loud) You can use rivatuner to control fans, but have to set it to come on 100% on windows load, otherwise the fans wont start till later (when it gets really hot) but thats hows its programmed in the bios, unless you want to flash the bios to alter that.

So at the moment windows loads up, starts the fans at 100%, then I have another profile which I change it to 35% (and stock settings) and then can't hear the fans. If I started it at 35% straight away only the right fan will spin. When I game I change to 50% fan speed and have it overclocked slightly (haven't experimented too much or benched) but haven't had any problems with running it like this.

I could have done a better job with the heat transfer compound which i botched up a bit during install, and would probably be better to use or modify a heatsink to cover that chip properly, but its staying under 50 degree while I game and even overclocked and its silent while idle in windows so its doing its job as far as I'm concerned.

Some people may like to try using 120mm fans, but I think that would take up more room, currently it takes up two extra slots, but would allow you to run a second 4870 if you wanted to do crossfire for most motherboards I'm assuming.
