Looks neat BUT it still need some improvements. 1. connect the rams/VRM to the main heatsink instead of cheap stick on heats sinks.

2. 120m fan addon like the ninja scythe. To make it a 3 or 4 slot cooler

Meh, the RAM chips would probably be heated rather than cooled should they be connected to a passive cooler. They're only a couple of watts, so they should keep cool enough on their own (see tests where RAM heatsinks don't really improve overclocking)

Any idea on when they'll be available and cost? I've got a spot in my P180 for that thing!! :)

Can this be mounted on 8800gts\x with a 120mm low rpm fan?

According to AC's website the S2 also comes with 8 memory heat sinks. 8) Unfortunately they don't have any pictures of them or more detailed pictures of the S2....

Does anyone know what this optional Turbo Module is? It must be a fan of some kind, but I can't find any information on AC's site or a Google search. :?: It will be interesting to see if it is just a clip-on fan or a slot fan/blower similar to their Silencers.

If you are looking for additional cooling performance or have very little airflow in your case you can install an additional Turbo Module that uses an active fan to improve cooling.
The RAM heatsinks are just regular RAM heatsinks as you can see here:

I can't wait see this how this preforms in comparison to Thermalright's HR-03, and Aerocase's Raven and Condor. :D Especially in low a low air flow situation!

Pity you can only mount them underneath the card, I would have preferred dual mount, i.e. the heatsink mounted on top for easy hot air exhaust. Right now it works fine, but it means air is taken from the slot underneath the card and hot air heated from the card must pass through the case before it's exhausted. Current solution will work fine for low powered cards, but I'd be weary using it with power hungry cards.

We now have a review of the S2 on a 7600GS card.

It thoroughly kicks arse - silently :twisted:

http://www.rbmods.com/Articles/Arctic_c ... lero/1.php

If the S2 is that good with 2 heatpipes on a mid-range card, I have high hopes for the S1 with 4 heatpipes.

7600GS is a low end card both in performance and power requirements. It doesn't even need external power connector. xbitlabs estimates power draw of only 27.4W under load, so I'm not really impressed with S2 performance yet. I would like to see S2 tested with cards up to 75W and S1 tested with 75-130W cards before making a judgment.

I think it's time SPCR tested new set of GPU coolers like HR-03 and S1/S2, along with Aerocool VM-102 for kicks. Should be a worth read. *HINT*HINT* :wink:

IMO the S2 should do well on 7950 GT or 1950 Pro. The HR-03 should be close, maybe even better with good airflow, but the VM-102 will end up last.
The S1 is the real thing, having 100-120W max heatpipe capacity and the large fin area, why is it not yet available? :evil:

I was looking at the performance of the card compared to the allowed max temp and comparing it to the generic cooler the card comes with.

Most GPU's are OK at 100C and often up to 125C. If we estimate that the ambient temp (outside of the case) is a mere 20C and say add 5C to the inside temp that puts the case temp at 25C (probably 5+C higher in reality). The temp rise under load is only 23C for a 27W card. If we tripple the 27W and the 23C we get an 81Watt card and a 69W above ambient temp, when we add the 25C ambient to that we get a card that maxxes out at 94C. Thats not bad for a totally passive card, and I believe that in an SPCR readers PC the temps would be much lower.

All of my sums above are up for scrutiny/debate/verbal abuse, and of course the original system that this cooler was tested in - which we dont have any information about apart from it having the side on.!

These two coolers are a must for SPCR to test.

I agree.

IMHO 16°C improvement from an aftermarket passive solution is just great. And I expect the difference to be even greater in low-airflow environment.

BTW I'm joining those calling for SPCR review. :wink:

I wouldn't trust max safe temps. Those temps might be max safe temperatures in a sense that the card is guaranteed not to fail if it reaches those temps, but it doesn't mean it will function perfectly fine at those temps (especially for prolonged periods of time, same as CPUs really, run them overcloked too much at high temps for long and their max overclocking frequency will degrade).

My 6800GT is also rated up to 115 or 125 degrees, yet, it craps out way below that, I believe about 80-85 degrees, and I'm not alone. I've read several other reports about ATI and nVidia cards becoming unstable when reaching those temps, so while your card won't be damaged, you will likely get artefacts/frozen PC/blue screen/hard reboot.

According to this spec sheet from AC website, S1 is targeted as a solution for 6800 series.

Spotted at Snowbit in Hangover - the S1's "Turbo Module".

No one should be surprised that it involves fans, but it actually uses 2, and I have no idea how they are actually attached, scroll to the bottom of the page to see it.

Also a new HUGE cooler for the G80 and R600 series at the top of the link.

Those turbo modules look pretty slick, but I'd probably still not use them. The cooler for G80/R600 IS MASSIVE! :shock: Being an AC product I would like to think those things aren't noisy but 3 80mm fans? Come'on that's just over doing it! Personally I thought the turbo module would be a fan that could be attached on the side of the heatsink, so it would blow air either to the back or front of the case.

I really cant stand the word because I hear it far too much, but AC really ARE a "Dynamic" company...... there I said it, the D word......

They are still smallish, they keep innovating, they keep on improving, and they rarely fail (their cases are their downfall... but for how long), however they still have never grasped the high end OR the ultra low noise markets. Maybe they are not interested, but they still innovate, and bring new products to the market, its a shame that the S1 and S2 are nearly 12 months late.

And I have no idea from those pics how the fans are attached - if they even are.

More to the point those fans dont look like the new "quiet" breed of AC fans, they look like the old OK versions, and the literature "suggests" that they are soft mounted, but are they.???

Unfortunately speculation is high on the list, parts in the wild are not, so no benchmarks for a while folks.

Reading the text in the picture below the fans should give you an idea: "clips for easy installation". :wink:

This X1950XTX Crossfire setup is passively cooled by S1s: http://www.madshrimps.be/?action=getart ... rticID=550
The picture shows how large is the area exposed to case airflow, they almost touch the case panel when closed!
Of course, there's no mention of case fans speed, so it probably won't perform as well with a 600 rpm Nexus in the back, but it should cool my 7900 GTX.
