Accelero twinturbo and Crossfire? * Does NOT work! Not out of the box anyway * I just bought the Accelero twinturbo for my two cards, Asus 4890. http://www.arctic-cooling.com/catalog/product_info.php?cPath=2_&mID=101 (All temps in this thread are in Celsius, °C) After installation i was very dissapointed with the temps. I noticed temps exceeding 100° on both Memio and VDDC slaves. At one point i aborted the benchmark since one VDDC showed 135° in GPU-Z...card survived. So i did the only thing i could do, removed both cards. Double checked the cards to see if i missed something. Installed one card and booted up. Now the temps are outstanding. The highest value i get in idle is @ something called " ??? Slave #2 " which shows me 63° now. Under full load after several loops in 3DM Vantage the highest value is the same VDDC Slave and it shows 83°. I am happy with that. The cooling solution works and is very quiet. The problem is offcourse(or atleast i think that is the issue?) the card on top will suck hot air from the card below. I have good airflow in my NZXT Tempest (air flow king case) Also there is a 120mm side intake, that blows right over the Accelero and graphic cards. This doesn't seem to be enough tho. So my question to you guys here is: * How can i get it to work with my X-fire setup? * Can i put the card even further down to my 3rd PCI-E slot? (If i can get a longer Crossfire bridge that is) Probably it will go @x16 / x8 or if i am unlucky x16 / x1. How much will that decrease performance? As it is now, the card on top is very close to the card below, it is no gap what soever, the "fancage" on the Accelero is almost touching the card below. I understand that the Accelero isn't Crossfire approved or anything. But there must be something that can be done to improve this. My system: i7 920 @4GHz with a Noctua NH-U12P Asus P6T DeluxeV2 OCZ Gold 1600MHz 3x2Gb Corsair HX750 2x Asus 4890 Some harddrives Case: NZXT Tempest. The temps on the CPU is around 38° idle and goes up to around 55-60° while doing 3DM Vantage. Sorry for bad english and/or spelling issues I would be very grateful for any feedback on this!
