You will not be able to keep the 590's cool in the R4 regardless of the power requirements.
Well I don't know what you guys did, but I just got my Aurora r4 and have gtx 590 working SLI, also installed the new 1. 1 power supply. No heating problems and perfectly working.
How exactly are you defining "no heating issues"? It's a rather subjective statement without some data behind it. Your definition may be that 95C is perfectly fine while I think 70C is a problem. I'm exaggerating here, but for your information to be useful to others (and I don't doubt that you want it to be) please post info like:
"My system <specs in sig> runs at xC when under y load for z amount of time. I have it configured with n settings."
Please know that I'm NOT trying to flame you; I just have a serious personal interest like everyone else about our systems, how to improve/fix them, and help others do the same (I happen to be professionally interested as well).

i am so glad I found this site. I have had my Alienware for a year and 20 days and it never worked as promised. I am at work now when I get home I got some many questions. I have to get my specs and link them, But basically Dell is sending me 590 GTX to replace my 295 GTX for 300.0 dollars, sound fair should it be free?
