Hmmm
My unit uses R507 aswel, meant to perform a little better than R404 I believe, or is it the other way round,
Never can remember,
Mine gets down to around -50 unloaded, and was holding an e7300 @ 5G 1.8v at -40 or less,
I wouldnt buy unless you know more about the unit.
Rotaries arent often used in SS as they are more power hungry, and while they perform better, often not enough to warrant the extra room needed/power draw....
