Will these fit in crossfire?

Paulieg · Jan 30, 2009, 01:04 PM

I need to replace the cooling on 2 4850's that I just bought. I'm thinking of replacing them with the AC S1 Rev2 cooler, but I'm concerned that they won't fit in crossfire. I don't want to order them, and be wrong. Do you guys think these will fit OK in my setup. Here's a link to the coolers, my board, and my case. Keep in mind that my WC rad is installed in the bottom of the case.

Which slots are the Crossfire slots? The Blue ones?

When I had the S1 it used up 2 and a half slots with the S1 and the turbo fan kit. I rigged up 2 120mms to the S1 to get better cooling and it took up 3 slots.

It is the blue slots. I plan to run them passive, since there is a 240mm side fan for airflow. Think it will fit?

I don't think it'll fit. The PCI-E connectors are just too far apart. Because of the cooler, your crossfire cable has to be over it before reaching the other gpu.

Take the plastic bits off and the S1 is no taller than the card.

I think it will fit, quite easily.

Can anyone confirm or deny this?

What about the crossfire connector? It seems connecting the cards might be a PITA? Thoughts?

Agility · Jan 30, 2009, 01:35 PM

As you can see the cooler is of 32nm height. Plus it protrudes out of at least 8nm. What's the length of your card?

The longer crossfire bridges should work. If I'm right, there should be a 5 slot length version. (i think)

Agility · Jan 30, 2009, 01:38 PM

Btw paul, the cooler seems to take up 2.5 slot of the PCI. So you might want to measure it for the 2nd 4850 (the one nearer to your WC radiator.)

Really?

Just another FYI, the AC S1 works just fine with Crossfire as long as you only need a single cable...the cable will slip easily between the fins on the edge of the S1.

If you need to run two Crossfire cables (older, pre-3xxx series cards), it'll still work, but it requires bending fins by the first heatpipe to make room to feed through the cable end of the second cable, then bending them back into place. The cable will be kinked a bit by the heatpipe, and the fins will never be 100% straight, making the whole deal a bit ugly, but it works.

BTW, been running a pair of them since November, my overclocked 3870's stay at 38/33c in 21c ambient idle, and never ever hit 60c under load, even with hours of COD4. Still using the stock mem/vreg coolers on the cards too.

I dont know if he is referring to the second revision of the S1..

I have that cooler on both my 4870s, just carefully seperate the fins and attach the bridge. Works like a charm!

this was referring to the second revision.

Just some stuff google turned up. I think it will work but you need to "make" it work.

Hey paul try this website i found.

Connecting a crossfire connector is no problem. The sides of the Accelero look like they are made out of a solid piece of aluminum, but actually it's just each fin that's bent downwards. You can easily slip in a crossfire connector without any issue.

Actually, the Asus board came with the lond flexible crossfire bridge. Thanks guys.

I saw you say you wanted to run these passive... I hope you're kidding.

LOL. Yes and No. I ran a 8800GT with one of these about a year ago. Even overclocked, with good case airflow, I really didn't need a fan attached. My HAF has both a 240mm front and side fan, along with excellent cable management. I bet the S1 with good case airflow will cool the cards better than the stock coolers do. Wanna bet?

TRIPTEX_CAN · Jan 30, 2009, 03:10 PM

I know the HAF side fan can keep those cool. They have such a large fin array that a fat lady within 3 meters could break enough wind too keep them cool. I think you should still mount some fans and vmod the 4850s.

JrRacinFan · Jan 30, 2009, 03:14 PM

Paulie, whats the max res of that 20"? Just curious so you dont have issues running a single bridge.
