--------------------------------------------------------------------------------

looking at the possibility of getting an accelero s1 (http://www.newegg.com/Product/Produc...82E16835186054), or something else similar to mount to a Powercolor AX7850 (http://www.newegg.com/Product/Produc...82E16814131464)

I will be sticking this into a relatively small mATX enclosure (Asus V3-P5G33: http://support.asus.com/download.asp...wC5cR1KFeHkbEL )

When I measure my clearance from the top of the PCIE slot to the bottom of the side panel, I get 14cm- the listed vertical size of the cooler. Is this thing going to fit without cutting up my case?

I really want to reduce noise, as the increased noise pollution for this from my previous card (HD-5770) is annoying, even at idle....

If the accelero wont fit, what is a good quiet cooler to pop on to this card?

I will define dimensions as follows: with case laying flat (CPU fan on on top as I look)

Height from top of the actual PCIE slot= 14cm
Width= current 2x slot cooler, 1 slot available on side towards bottom of the case, 0 slots available on side towards top of case due to PCIE 1x tuner in that slot
depth= 33cm to front panel board

with that being said, if the accelero takes up 3 slots INCLUDING the slots of the Video Card (taking space consumed from 2 to 3 including addition of a fan), and the height is sufficient, that works just great.

I guess this is where my mATX case really hits it's limitations...

(I am running an Asus P7H55-M Pro for thos who feel my slot configuration makes little sense)

If you have no expansion cards below the graphics card, you should be fine in that regard. As far as the physical size of the S1, it's a large cooler. You will need 154mm from the motherboard to the edge of the case for it to fit comfortably. I have two 4850's with S1's on them, and I just measured from the edge of the PCI-e connector to the tip of the heatpipes.

The Asus V3-P5G33 only uses only a 92mm rear fan, so I think you may be short on width for this cooler. Your case needs to be about 12mm wider to fit the S1.

The Arctic Cooling Xtreme models might be able to squeeze in there, I have one at work I can measure in a few days, mounted on a GTX285.

The thing about these is that they mount on the GPU core, not the edge of the PCB, so you have to take the measurements with a large grain of salt when planning.

The AC Twin Turbo II should fit in the case, but first check the GPU position on the PCB (I couldn't find an image of your 7850's PCB).

how about this: http://www.newegg.com/Product/Product.a ... 6835186053

Accelero L2 Plus

looks to be much smaller, and reports itself as a 0.4 Sone cooler..
