Thanks for the post jojo4u,
Unfortunately, I could not find the review online (not that I read German but I wanted to glance at the figures).
Since SLI is not really interesting to SPCR I left out the 100% figures
The C't is a first of all printed magazine but you are able to buy the articles online.
There are no additional figures about efficiency or power distribution. But i scanned the noise figures available here
. The noise level is in sone, the transparent columns are with fan speeds set to highest level.
