Desperate for help on troubleshooting PC failure (PSU or CPU liquid cooler?)

Hi all,

So it all began after I started playing Overwatch this week, which is the most hardware demanding game I've played since I built this PC a year ago.

For the last three days, I've had random power outages while playing the game because it keeps on tripping the AFCI breaker for my apartment bedroom (here I assure you that I am absolutely not overloading the circuit in any way). Originally I attributed this to nuisance tripping of AFCI breakers or potential faulty power supply. However, every time the power supply would turn back on perfectly without any problem and the PC starts up normal after I flip the breaker switch back on. However, during the last three days I did notice once that when I turned the PC back on my Corsair H110i GTX's LED turned red which indicates hot CPU temperature.

It was until today that when I was playing the game, the game became super laggy. I then opend up HWinfo and I saw my CPU temperature is at 90C! I then looked at my liquid CPU cooler and see it just completely failing (fans not turning, LED not illuminating). However, after shutting down and rebooting the CPU cooler is working perfectly again! So strange. I was wondering if this is more likely the liquid cooler's problem or the PSU problem. Note that I also do have the liquid CPU cooler hooked up to the same SATA power cord with another SDD and HDD. I don't know if this could cause the problem as well.

My build is as follows (no overclocking of any sort, not the CPU, not the memory XMP profile):
i7 5930k
Corsair H110i GTX liquid cooler
ASUS X99 Deluxe MB
EVGA GTX 980Ti SC ACX2.0+ (x2 SLI)
Corsair Dominator Platinum 4x4GB 2666MHz Memory
Corsair AX1200i PSU
Samsung 850 Pro 512GB SDD
WD Black 1TB HDD
Corsiar 750D Case (with airflow front panel)

Thank you in advance for any insight or suggestion!

You should address the temperature problem first. The pump is probably failing on the H110i. What baffles me, though, is why the circuit breaker was being tripped.
