Just today I upgraded the standard air cooling on my Alienware Aurora R7 to a liquid one, the Masterliquid M120 Lite. My choice for this cooler was mostly space driven, as the Aurora's case provides VERY little room inside.
I installed the liquid cooler, which is working properly: I ran Intel's stress test and the Intel burn test and the processor if performing fine with temperatures never exceeding the 85C mark. However, booting has become massively slower: my system used to be up and running within 20-25 seconds, that is now 4-5 minutes. On top of that, during start-up I get some warning signs from my on/off switch: it flashes either once (which might indicate system board failure) or five times in succession (which indicates CMOS battery failure). However, after the entire process my machine runs smoothly as ever, including games, and tests provided by Dell and PC Doctor are not showing any errors at all. I think I should mention there is no monitor output whatsoever during 95% of the start-up. Only thing that is flagged is a fan error, which is probably due to the cpu-fan no longer being connected (as it is now replaced by a pump fan).
Is there something I forgot or should do when adding new (aftermarket) hardware? I tried the usual: double checking all cables on the system board etc.. Hope somebody can help me!

CPU: Intel i7 8700 up to 4.6 GHz
