I have tested Ultimaker 2 with their noisy duo of fans and it is not perfect with PLA and overhangs. See picture in the middle of the 2nd page of my review: http://www.3d-tisk.cz/ultimaker-2-legenda-s-citem-pro-detail-pokracovani-recenze/ (texts in Czech language, sorry). 
Much better was Zortrax M200 with ABS: http://www.3d-tisk.cz/zortrax-m200-spolehlivy-a-presny-dric-pokracovani-recenze/ (picture with many models on the mat – and also with overhangs test model).
You should be able to use retraction settings to eliminate any oozing on any hotend we sell. Adjusting temperature lower to find the sweet spot for that particular filament also helps
I feel a lot of people misinterpret nozzle temp. There is a silent rule that PLA needs to be printed at ~205C. I’ve been printing most of my PLA at 190 no ooze at all
@Brook_Drumm Thank you for advice. I try to for weeks as standard Cura settings doesn’t work for me in this area. And I will also change fillament for test (I have 5 spools from Fillamentum.com, now will try another material from Verbatim). And I will try again.
@Michal_Feltl I print at 185 °C. It depends on manufacturer and his additives. PLA over 200 is fine for cubic shapes during the winter time.
Carl prints at 185c on the new all metal “Ubis 13” hotend. It’s extremely precise with this temp and .3mm retraction… Beautiful prints, he says. He is especially proud of his small gears done in polycarbonate.

Sure thing!!
