AC Accelero S2 + 92 or 120 fan enough for GTS 250?

I just picked up a cheap Geforce GTS 250 1GB (Gainward Deep Green Editiion). It is slightly underclocked but the stock fan is still pretty noisy.

I would like to keep the card short in case I use it in a smaller PC at some point so I'm wondering whether an Arctic Cooling Accelero S2 with a zip-tied 92mm or 120mm fan would do the trick.

IIRC I have seen people using this setup on the similar 8800 models so I am presuming it should be ok on the GTS 250?

Thought I would check here just in case!

Hi,
My gainward 9800GTX+ (same as GTS250) runs without a problem with a slow 92mm fan on the Accelero. It could even run passive if you have good enough airflow and if you don't mind slightly higher temps.
Put any quiet 92mm or 120mm fan on it and you'll never have to worry about temps or noise.

I'm running an XFX GTS 250 with Accelero S1 rev2 passively without issues..

Hiya, are you running the S1 or S2 frenchie, I know the S1 should do the job but would prefer the S2 to keep card shorter (then it can fit in my spare system if I need!)

Back on topic : It's the S1 (with the 4 heatpipes), same as Wibla.

When you say keep card shorter, do you mean in length, width, or height ?

[EDIT : also, I'm not sure the S2 is compatible with the GTS250]

Yeh I mean lengthways. The S2 only has 2 heatpipes, but it is advertised as compatible with the 9600gt which I think is the same fitting as all the 8800/9800/250 cards?

Only 2 heatpipes but I wonder if they can handle it with a fan added!

GTS 250 isn't exactly a short card. Some quick Googling suggests they're about 9" long, and the Accelero S1 is about 8.5" long, so it shouldn't add much/any length to your card. Honestly I see no reason to get the S2 instead of the S1.

That said, S2 is a pretty capable heatsink. Should be able to handle a GTS 250 with any fan blowing on it. Passive cooling is likely a no-go, though.

The Deep Green is much shorter AFAIK, it may look like this:

I am interested to buy one, but I don't know how much less power it uses compared to a non-green one.
Also I don't know where the GPU socket is located, if it's moved towards the back, then the S1 might not fit without maiming.
Passive cooling with an S2 seems impossible to me without massive case airflow. Maybe the OP could post a couple of pictures of his card?

Judging by the fact that many gts250s ship with simple extruded aluminium heatsinks, I`m sure the s2 + a fan could handle it. What I don`t know is how fast you will need to run the fan at load and unfortunately it will be quite hard to find anyone who has tested the s2 with such a card. The biggest problem of the s2 is ... the s1.

There are other, more compact coolers that could do the job by Zalman, Xigmatec, Skythe etc (Zalman vnf100 would be my favorite). None is as good value as the s2 but on the other hand, most of these have been tested with cards similar to the gts250, so you could get a better idea of what to expect.

This is easy. The S2 doesn't fit the GTS250/9800GTX. You have to get a S1.

Could someone maybe comfirm whether the little RAM sinks are sticking properly nowadays? I know there were problems with the sinks falling off in earlier shipments, but I guess they could and should have corrected this by now.

I really don't want to glue the sinks in place due to warranty issues.
