Hey guys,
not a while ago i've purchased new Samsung monitor (U32H850UMU). My problem is that when the monitor is connected with DisplayPort to PC, on boot i got CPU Fan Error. Now, if i switch the connection to HDMI (same monitor ) - boot is perfect. And if i connect my old monitor to PC (not through DisplayPort) the boot is also perfect.
Someone got any idea how to solve this odd issue?
 
Solution
Try a new Display port cable. My display port cable failed and my system wouldn’t post at all. If your monitor and GPU both support HDMI 2.0 you should be fine using HDMI.

Be glad you found it was the display port cable. I took my system apart three times. I’d take it al the way apart and it would boot connected via the motherboard’s hdmi connector. Once I’d get to reinstalling my GPU and using my DPP cable it would fail to boot making me think my GPU was faulty. At some point I finally tried HDMI from my GPU and it booted completely fine.
