Question regarding performance.

Hello,

So i have a mbpr 15" late 2013
2.6 Quad i7
16gb 1600mhz

nivida gforce 750 (2gb gpu)

Up to date on everything

i am using 2 Dell u2515H on full resolution 2560x1440 Resolution, The macbook is in clamshellmode, and i am connecting everything as such
1 tb to a thunderbolt dock

1 tb as displayport to the other.

My macbook is running the fans like crazy, and i am not doing anything, I have tried setting the displays to 1080 or something lower, but the fans are still warping.

My old macbook pro could run two screens with no problems, fans only kicked in when i started to work.

Surely the gpu should be able to handle this.

And yes, i connect the charger, connect the thunderbolts and then press my keyboard to go into true clamshell.

Any help would be gladly received.

best
Johannes Drakenberg
