Review: Latest Scythe VGA-Cooler with superb potential  

This review is also available in German.

 

Exactly one year ago we reviewed the first Setsugen VGA-Cooler from Scythe. Today we take a look at the new Setsugen 2 which is radically different from its older brother.

 

Scythe Setsugen 2 Package

 


Overview:

As can be expected, the compatibily list has greatly improved and now covers pretty much any nVidia GeForce Card up to GTX 470 as well as Radeon HDs up to 6870. Because the cooler went on sale in Japan before the HD 68xx cards where launched, you won't find any mention of these cards of them on the package or installation sheets. This cooler would also cool the GTX 480/580 cards, but because the VRM regulators are on the left side of the card you need additonal cooling to keep the cards from damage. The package contains lots of additonal parts. To save money Scythe did not include PCIe 6pin power extender nor a second PCIe 8pin power extender which would protect the cooler if you need to swap your card more often. Due to the size of the cooler it's quite hard to remove the power-connectors.

You will notice the shape of the cooler is more quadratic and the four heatpipes go twice through the aluminium fins to optimize heat-disappation. It measures 176x139x33mm which will make any graphics-card into a two slot design. The overhanging portion of the cooler will hinder its use in Mini-Tower cases. As usual, the workmanship is excellent.

As expected from Scythe, the workmanship is excellent, but nickel-plated heatpipes would not have hurt.

For some reason Scythe sticks to the annoying fans with fan-controller bracket. It would be more usefull to supply a cable with adapters for common 3-pin and 4-pin graphics-cards fan-connectors. This would allow the graphics-card to control the fan depending on the temperature and would also save a slot. Of course it's recommended to keep one slot free, but nowadays extremly short-sized PCIe adapters are available which would not hinder air-flow. The overhanging cooler-designs prevents heat accumulation directly on the graphics-card.

If you are as annoyed as we with the fan-controller, you can use any other 12mm slim fan to either keep the two-slot design or fit a 25mm fan with cable straps which will improve the airflow greatly. As you can see the identical fan without the controller is available for about €6,30. Both fans rotate up to 2000rpm and the airflow is up to 78m³/h or 45.5CFM.

Now let's build the Setsugen 2 on the HD6870. The installation is quite straight forward but fiddly especially when fixing the screws. You can't see the holes where the screws must go in because the scews are going through the back of the card. This is the only problem mounting the Setsugen 2. As usual make sure all chips are clean before strapping the heatsinks with adhesive pads - press them properly and give it an hour before installing the cooler. When you are done, the card should look like this:

Scythe Setsugen 2 on HD6870 without Fan

For our first tests we used the fan that came in the package. The new fan-mounting clips are much easier to use compared to the previous Setsugen. Any 12mm fan will fit. If you decide to use a standard 25mm fan, you need to use cable straps and the card will exceed the two-slot design.

On the backside you see the screws which gave us some headaches. The mouting plate is coated with a thin plastic cover to prevent potential short-circuiting.

Even as two slot design, the card now weights a ton less, because only the GPU plate and the heatpipes are made of cooper, while the rest is made from aluminum. The cooler weights only 435g and even with the heatsinks you should not exceed half a kilogram.

The cooler is about 5cm taller than pretty much any graphics card, so make sure your case can fit the cooler.

After strapping our graphics-card with the Setsugen 2, you need to connect the fan to any fan-connectors on your mainboard or via an adapter directly to your power-supply. We chose our mainboard. We turned the knob to the lowest possible setting and set the fan in the mainboard BIOS to 100%. That resulted in about 760rpm and the fan to be inaudible. AMD Radeon HD6870's stock cooler is almost inaudible in idle mode, but the Setsugen beat it there too. Of course at full speed the fan rotates at 2000rpm and is very audible, but still much more bearable than anything AMD has to offer.

Scythe_Setsugen_2_hd_6870_stock_idle_ab

40°C in idle is nothing to worry about but at nearly 1087rpm, the cooler is audible.

 

sycthe_setsugen_2_hd6870_low_fan_idle

As you can see, even with the lowest setting the idle temperature is 3°C lower compared to the stock cooling.

 

sycthe_setsugen_2_hd6870_1000rpm_fan_idle

For more balanced cooling we would recommend to set the fan to around 1000rpm, which is what we did. The fan is nearly inaudible and Setsugen 2 shaves off another 2°C.

 

sycthe_setsugen_2_hd6870_full_fan_idle

With 2000rpm the temperatures go down about another 2°C but is quite loud. It's not unbearable like the stock-cooler at gaming, but we still considered it loud.

 

sycthe_setsugen_2_hd6870_25mm_fan_idle

We found a 25mm fan from Scythe from the first Ninja cooler which was quieter than the newer models. You need cable straps to fix the fan on the cooler but this is minor annoyance. At 75% setting in the BIOS, the fan rotates with about 960rpm. It's also nearly inaudible but due to the bigger blades it can push more air. As you can see the temperatures are steady 34°C which is the same as the original fan at full speed.

 


Scythe_Setsugen_2_hd_6870_stock_furmark

The Catalyst driver does slow down the card under load but we did not find any game which would exceed Furmark's temperatures or fan-speeds. As you can see the stock cooler heats up to 85°C and the fan is very loud - more annoying compared to the Setsugen 2 at full speed.

 

sycthe_setsugen_2_hd6870_low_fan_furmark

Even with the lowest setting at 760rpm the Setsugen 2 beats the stock cooler by up to 5°C. All in all, 80°C is safe for GPU standards.

 

sycthe_setsugen_2_hd6870_1000rpm_fan_furmark

With just 1000rpm the temperature drops another impressive 7°C.

 

sycthe_setsugen_2_hd6870_full_fan_furmark

At full speed the Setsugen maxed out at 64°C. But of course, we don't like it that noisy.

 

sycthe_setsugen_2_hd6870_25mm_fan_furmark

With the 25mm fan at 960rpm the Setsugen manged 68°C which is 17°C less compared to the stock cooler.

 


Just to prove that no game can come close to Furmark temperatures, we also tested with the Lost Planet 2 Becnhmark, but we avoided the stock cooling due to the noise.

sycthe_setsugen_2_hd6870_low_fan_lp2

While Furmark maxed out with 81°C it's pretty clear that actual games will not reach such temperatures. With 69°C at it's lowest setting the Setsugen 2 is more than sufficient for cooling the HD6870.

 

sycthe_setsugen_2_hd6870_1000rpm_fan_lp2

At 1000rpm you get another 5°C off the card.

 

sycthe_setsugen_2_hd6870_full_fan_lp2

At full speed another 7°C are shaved off the temperature-scale.

 

sycthe_setsugen_2_hd6870_25mm_fan_lp2

As expected the 25mm does not do so well compared to the slim fan at full speed, but 61°C is just great for an inaudible cooling solution.

 


We also tested the DX11 version of Lost Planet 2. Besides a massive drop of fps and little more eye-candy, the reduced framerate also had an impact on the temperatures.

sycthe_setsugen_2_hd6870_low_fan_lp2dx11

With less than half the framerate compared to the DX9 version, the temperature reaches only 63°C.

 

sycthe_setsugen_2_hd6870_1000rpm_fan_lp2dx11

At 1000rpm it manages 61°C, just 2°C shy of the lowest rpm setting.

 

sycthe_setsugen_2_hd6870_full_fan_lp2dx11

Just 54°C at full speed is impressive, some passive cards would like such temperatures when idle.

 

sycthe_setsugen_2_hd6870_25mm_fan_lp2dx11

With the 25mm fan we also managed to get under 60°C.

 




Conclusion



We'll start with the cons - we don't like the fan controller. There is no reason whatsoever that makes sense for such a move. In future versions we would like to see adapters for the graphics-card fan-connectors. Also, the installation of the cooler is fiddly and to have stud bolts with screw nuts as the first Setsugen had would have made installation much easier. Furthermore, the installation instruction sheet is a joke with such small letters that you may have to use a magnifying glass. A small CD with a real manual would be the better choice. Due to the size of the cooler with its rather unusual design, you'll need a case which offers 5cm space to the door otherwise the cooler won't fit. That's a down compared to the first Setsugen which fit in any case.

However, and we really do love those "howevers", once you have installed the cooler the results speak for themselves. HD6870 is a midrange card roughly as fast as the older HD5850 and with the TDP slashed by 20W, but even the lowest fan settings on Setsugen 2 offer sufficient and inaudible cooling. The product is certified to cool anything up to GTX 470 series. You may even install it on GTX 480/580 cards, but the VRM portion is located on the left side of the card, so you need to cool that seperately. The installation on a HD6970 should be possible because the fan will cover the VRM portion, although you may need to improvise with the heatsinks and set a higher fan-speed. Even at 1000rpm or with any 25mm fan running at similar speed - the cooler stays very quiet.

The cooler will be released in Europe and USA on December 3rd and should retail about €35,- to €40,- which is not cheap but justified. The first listings have appeared and you can check them out here.

There are a few quirks, yes, but actual performance is flawless. So, if you want impressive cooling without the common noise, then Fudzilla Recommended Scythe Setsugen 2 should definitely be among the first on your list.

 

recommended-2010

 


On of our users requested an update with a HD4890, which should be a little hotter compared to the HD6870. Our HD4890 is clocked at 850MHz for the core and 975MHz for the memory. Overclocked versions will of course get hotter. We were pretty impressed with the results so we didn't bother testing at 2000rpm.

 

HD4890 idle temperatures:

sycthe_setsugen_2_hd4890_low_fan_idle

Idle temperatures at 760rpm.

 

sycthe_setsugen_2_hd6870_1000rpm_fan_idle

Of course lower with 1000rpm.

 

sycthe_setsugen_2_hd4890_25mm_fan_ide

Idle temperatures with a 25mm fan at 1000rpm.

 

HD4890 Furmark:

sycthe_setsugen_2_hd4890_low_fan_furmark

760rpm; indeed very impressive.

 

sycthe_setsugen_2_hd4890_1000rpm_fan_furmark

At 1000rpm 5°C less.

 

sycthe_setsugen_2_hd4890_25mm_fan_furmark

The 25mm fan at 1000rpm is of course the best.

 

Lost Planet 2:

sycthe_setsugen_2_hd4890_low_fan_lp2

At 760rpm we nearly hit Furmark temperatures, but nothing to worry about.

 

sycthe_setsugen_2_hd4890_1000rpm_fan_lp2

1000rpm; on par with Furmark.

 

sycthe_setsugen_2_hd4890_25mm_fan_lp2

The 25mm is, as usual, the most efficient.

I dont wana be rude, but that was one of the worst reviews I have ever read... First just want to ask. why did you pick the HD6870? There is no issues with this cards temps or noise. Would make a whole lot more sense to review it with a actual card that people would seek alternate cooling. like the GTX 470. Next up. I like looking at Afterburner shots as much as the next guy. all 20 of them. but surely this would be ALOT easier if u just put all the stats in a little bar chart? i mean 4 pages of Afterburner shots is just too dam much!

First, you are rude.
Second, if you don't think anything wrong with the stock cooling, that's your choice. For me, the noise is unbearable under gaming. Just accept there are people who are sensitive to noise, especially if they are causul gamers and don't use their soundsystem at maximum settings where noise would be irrelevant. Some have to work with there machine too and they like it silent.
Third, it's not the case we could keep any card we get, so all the GTX470 were returned. So, if you have a GTX470 lying around which you don't need, please send it to me. I would have prefered to test it with a HD6950 or HD6970 if they would be available. And I do not set the launch dates for Scythe :D
Forth, a chart would not show GPU utilization, which I think is important.

When you work on the pc the card goes into idle mode is near silent. simple example of a chart would be like this

i concur with freddy,
this is a limited review..

more comparisons,.. throw it on a REALLY hot card..
or try to overclock the one u used and see how much burn you can get from the gpu , and how much the cooler can REALLY handle

also, you throw a very big personal stamp on this card by saying you dont like this and that,
but try to make an objective review..
in a lot of situations, a seperate fan controller is very welcome,
its not like you have 5 of them on the back of your comp anyway

and indeed,
its not hard to throw some data into office and make a nice graph

It's fine .
What's the issue with putting a 6870 ?
Or you guys fed-up that your Nvidiot is a real sucker ?

well tbh, the nvidia gpus are the ones that run at 70deg C+, and need the cooling most.
 
 
+1 #7 Supercrit 2010-11-29 22:13
I think this cooler is for people who want a thin cooler that takes 2 slots max, while having better than stock temperatures, not for pure performance, since most performance coolers take 3 slots(fan included)
 
 
0 #8 Wolfdale 2010-11-30 01:51
i mean.. i use 2x 4890 myself, and while this review obviously gives some insights, i wonder what the cooler would do on other cards BUT the 6870 tested (not all cards are unique anyway)
my 4890 runs on 1000mhz/5500mhz
so yeah, i wonder what this cooler would do for my card, i know my t-rad2 has a easy job for it..
but i did have to apply additional VRM heatsinks (not those crappy sticker ones)
because i actually burned one card cuz of overheated VRM's WITH the t-rad2

right now it works like a charm, but yeah i wonder what this one *could* do for my cards and the insane ammount of stress caused by my VRMS (ive seen em go 90+ even with heatsink screwed on)
but no much info about that either

I can assure you, that a HD4890 can be cooled very easily. In some minutes I should have the tests online :-)

thanks for the update eliot,
appriciate it, and indeed these are good figures,
i do wonder how hot the VRMS got during those tests, and if you modified any way of cooling on them during the tests

i know for the 48## cards, the vrms are the bottlenecks for serious overclocking and/or custom cooling,
as i said, i actually managed to fry one, even tough core temps were well within limits, but i forgot to take notice of the boiling temps going on at the vrm's
