4870 X2 cooling

I would like to know if anyone has modded the cooling solution on their 4870 X2 card. There is currently no aftermarket coolers for this cards. I have heard that arctic cooling is working on one but it is still in the engineering phase. Until one is brought to market(if one is) we have to make do on our own. I have replaced the stock TIM with ASC and modified the fan speed with software.

the newest CCC has adjustable fan speed.

i have a fan at the bottom of my case blowing air up towards the 4870x2 fan... works a treat... with the x2's fan set to 45% the warmest chip is around 50 degrees under load and is in the mid 30's when its idling...
