I decided to ditch S1 because I found my idle and load temps on the GPU were unaccepable 60c idle and 90-100c full load. Which is very strange because in my Chenming case I wouldn't break 50c idle or 85c load. That case had a slim 80x15 fan flowing on the S1 while the advanced has a 120mm blowing on it.
I thought about slapping a fan on the S1 but it would block 3 slots in my rig so that was out of the question. The only open PCI slot was being used by my X-fi Music, so I picked up the an Accelero Twin turbo pro today after reading some reviews on it last night which claim it only blocks 1 additional slot.
So I get home install the thing and it blocks 2 1/2 slots and I can't keep the x-fi installed with the cooler I blame Xbit review on that one
So now i'm going to replace the x-fi with a PCI E version which I can install above the videocard to solve this issue. I wanted to do this eventually but this has forced me to do it sooner.
Here are some pictures of the swap will post more tomorrow.
I decided not to use any of the heatsinks that came with twin turbo because if you look at the picture the 4890 already has stock heatsinks covering the VM's only thing not covered is the memory.
Now if you focus on these last two pictures you can clearly see there is plenty of room for the ram sinks under the new cooler. However, I choose not to install them because they don't fit under the stock cooler and as much as i've enjoyed this card she will be replaced probably with a 6870 and I need to sell it with the stock cooler on. So for now ram sinks will stay off.
