I have an Nvidia geforce 8400 GS and purchase Accelero S1 R2 at first. Turns out it wasnt compatible I suppose. So I purchased the S2 which says its compatible with 8400 series. What I dont see is when installing it, you place spacers on the mounting bracket. But doing that the heatsink of the cooler does not come in contact with the GPU. There would be a space in between. Also, it cannot be installed without the spacers due to capacitor height. I am not sure what to do. I dont really want to buy a third cooler because I always fail to return them if they dont fit. I will end up with piles of coolers, lol. Any help would be greatly appreciated.
If you are any good with a soldering iron, you can move the capacitors to the back of the card. -or- If you are any good with a dremel, you might be able to make notches in the cooler so the capacitors don't touch (just don't cut into the heatpipes).
