Would monitors attached to my USB hub make my CPU run hotter? Would having 2 monitors attached to my USB hub (along with 1 monitor attached to the MiniDisplay port) contribute to the CPU getting hotter?

My MacBook:


Core i5@2.5-GHz
16-GB of RAM
1 HooToo 7 port USB hub
2 Diamond USB Multi-Display Adapter
the USB Display Adapters attach to HP 2511x (25") and Samsung S24D300 (24")
the MiniDisplay port monitor is HNC iF281D (28")
MacOS 10.11 (El Capitan)
I installed iStat to monitor things.


I just read in some forum that the CPU might overheat with more than 1 external monitor???  

I have been using this set-up for a few days. It is working fine.
I found the answer:

USB graphics devices, like the USB-HDMI-DVI, are “virtual” devices where much of the heavy lifting is done by the CPU, by hooking into the graphics stack. 

Even so, I'll keep this set-up and monitor things with iStat. All I display is MSFT Word documents and stupid web pages. I think I'll be ok?

Sorry I did not do more research!
