My Rig is Turning Off, is My Cooling Unit Failing?

The issue started about a week ago playing Tom Clancy's: The Division. My PC just shut down mid mission. It will start right back up though, and I was able to play no problem. Recently however, if I go into a game (or run Prime 95 on heat test) it will shut off.

Last time I looked at the figures on CPUID my CPU heat was somewhere in the mid 60s C. However the Package temp was mid-high 70s C. After checking several other things I am pretty certain that either my cooling system is failing (liquid), or my CPU is failing(?). So I have come here for help/insight.

Cooling unit is a Cooler Master Seidon 120V (its about 4+ years old). Lights are on, sounds like its running, but the radiator doesn't get hot, just warm to the touch. Not sure if that means its failing on me. The CPU is an AMD FX-8350, is it just outdated and running too hot?

Thoughts?

Full Specs:

Mother: AMD AM3+ ATX - ASUS Crosshair V Formula-Z
RAM: 32gb Corsair Vengeance Pro
Cooling: Cooler Master Seidon 120V
PSU: Fractal Design 750W Integra
GPU: GeForce GTX 780
CPU: AMD FX-8350
HD: Main is a 120 SSD with a 1TB standard as backup

So, it must be the pump although FX 8350 can be pretty hot when pushed, I know that my was pushing 200W at 4.9GHz and 1.55v. CM 612 evo and Mugen3 were able to keep heat pretty well contained and that Noctua should too.

I tried both OPT_FAN and CHA_FAN 3 (which are the only options nearby. CHA_FAN 3 worked well, I ran Prime95 for a about 5 min and it was in the mid high 70s. I let it cool and ran the real stress test, The Division. I played for about 20ish minutes and the temps kept bouncing around in the 70s slowly climbing up and down until it hit the 80s and my comp shut down on me again. I could hear the pump make a sound as if it were revving up every once in a while, but obviously I feel like this is a sound it should have been constantly making if it is really working. So here is my BIOS Fan Control Set Up:
CPU Q Fan Control: Enabled
Fan Type: PWM
Low Limit: 600 RPM
CPU Fan Profile: Turbo

Chassis Q Fan Control
OptFan 1 Control: Disabled
OptFan 2 Control: Disabled
OptFan 3 Control: Disabled
--The options for these 3 are 'Disabled', 'Duty Mode', and 'User Mode'

With control disabled it should run full speed. I believe it should be about 7000rpm. if you have an adapter, you could try running pump straight from PSU by Molex, such an adapter came with my Nepton 140xl. but don't have to use it because this MB has AiO_Pump connector and there's no adjustment for that header, full speed all the time.

So is it safe to say, that with the settings as they are, and the pump plugged in where it is, that if the cooler isn't keeping up with the CPU then it is failing and should be replaced? I had read that a lot of liquid units have a lifespan of about 4-5 years and this one is right at that mark. I was thinking of replacing it with the Noctua NH-U93, will this be able to keep up/provide the same cooling as my Cooler Master Seidon v120?

This was it! For some reason my water cooler has worked for four years plugged into either CPU FAN or OPT_FAN or CHA_FAN (I honestly don't remember which header I took it from) . That apparently was no longer giving it the juice/signal it needed. Stopped by my local PC store and they gave me a 3 pin to Molex adapter for $5, now my rig seems to be up and running like normal again!

Unfortunately after some more testing, even though it was going strong hooked up to the Molex, it started to fail and overheat again. At this point I would assume it is either an issue with the FX 8350 (which I have read run pretty hot when pushed to do so), or the Cooler Master Seidon v120, now at age 5, is starting to fail. I have ordered a new cooling unit, Noctua NH-D15, though this isn't a liquid system I am hoping a new cooler will make a difference, I will keep you posted once it is installed
