Macbook Pro w/External Display & SwitchResX Heating/Loud Fans Issue!!


so have huge loud fans/heating issue. here situation:

have mid-2014 15" macbook pro w/ retina display (2.2ghz). bought external monitor (dell u2515h - 25" @ 2560x1440p), , connected via minidp believe. when first connected it, realized how small was...the text, webpages, icons. did little research , found switchresx make texts bigger while keeping resolution @ 1440p. worked out great, did little math , worked out perfect custom resolution me (3840x2400 hipdi...so it's 1920x1200 displaying 2400). worked out great, text sizes perfect, icons, webpages.

problem, however, when play fullscreen video on youtube 1080p. whenever play videos, hulu...on fullscreen, fans become pretty loud. rpms averaging 4000-6000 rpm, , macbook pretty hot. dies down when video stopped. i'm web designer, can use photoshop...coding softwares, multiple tabs...and works fine without fans/heating issue. no, smc/pram reset isn't issue. problem when watch videos/let alone streaming movies fullscreen.

found out, last night, when switch resolution native (2560x1440p, disabling switchresx hidpi)...it goes normal. full screen video streaming not cause fan noise/heating. , rpm average @ 2500.

understand higher resolution, processor needs work harder. there fix? firstly, normal? if so, there hack make macbook think it's displaying 1200p fans wont loud? if not, there fix issue? bug related switchresx , hidpi? or cost of using hidpi?
