my cpu vcore voltage is at 1.3 but it has dropped down to .888 volts. so would people agree which i somewhat agree too maybe it is indeed the psu? and like i stated would a 750 psu be sufficient enough or should i get a higher?
If it's "vdroop" - then it's meant to, this is a built in safety freature to prevent voltage spikes from damaging the core when coming off of, or going to a load state.
The reason I say not to use/do overclocking yet is to help get the system back to a stable state. Not introducing more factors to the issue.
Factory overclocked default settings is fine - it's been 100% tested at the factory before release to be stable.
750W is fine for the PSU, it just matters if the rail is stable or damaged.
under high load voltage drops under bois set voltage
if the core voltage drops when the cpu is idle
thats the c1 idle states kicking in
lowering the core votage and cpu multi
try disabling those in bios too
its fine for a decent overclock on the 9590
cx750 is a good psu, capable for sli with lower power gpus, gtx970+ in that build
Cool air actually comes from the front intake fans of the case, across your motherboard, and then to your CPU (ensure cables don't block this flow)
You don't want to intake air from the rear, as the graphics card below that also exhausts hot air there, then goes up and recycles back into the case.
This should rather be a push/pull directing the airflow to the rear:
- front fan of the CPU cooler intakes (from inside the case)
- rear fan of the CPU cooler exhausts (out the rear of the case)
Rule of thumb:
- Front, Bottom (optional), and Side (optional) are intake fans
- Rear, and Top (optional) are exhaust fans
- Any Internal fans help that flow of air in the same direction (from front/bottom to top/rear)
- Hot air also rises and therefore follows that path
- Ensure there's enable space behind the PC case for exhausted hot air to escape (feel that it's not hot pocketing - hot air sitting stable behind the case and re-entering, just getting cycled around)
Here in Australia businesses like CyberPower wouldn't last as an initial 12 month warranty on parts and labour is mandatory.
yeah thats what i thought. it just kind of funny because the way my fan set up is working right now it cools it off better somehow. the way i had it before was the way you described and it was getting much hotter. yeah i dont think my fans are super powerful. they are all at 1200rpm in the bios. one fan is only 800. i will mess with the limits though just to see. i did change a few things around and tried metal gear, i started it at 6pm and let it run alll the way to 3, and my cpu only got to 45. when before it would crash my whole computer or bsod. so maybe i did fix it already. i am going to look into a better cpu cooling system i just only have a 120mm space for a cooler. any decent coolers that can keep up with a 9590 that is only 120mm?
Yes; the FX-9 CPUs are sold two ways; OEM or AMD Branded Retail Box without any cooler; and Retail Box with a bundled 120mm Closed-Loop AIO Liquid Cooler. In USA, 9590 sells for approx $299 w/ AIO; and approx $229 without.

Now, can it be cooled by air cooling without any liquid/rad type of setup; YES, but it would have to be a very high-end air cooler, such as Phanteks PH-TC14PE or something along those lines.
TBO, if I were the OP, that system (which OP says had troubles before already) would have gone back to CyberPower. I mean you have a warranty, USE it. Otherwise demand your money back and buy something else.
From my experience; generally there are two ways to best use AIO Liquid Coolers; A smaller 120 or 140 Rad based AIO; which if needed, make use of Push+Pull fan setup on said Rad and install the Rad in the Rear Exhaust placement of the case. But instead of having those fans blow out, have them blow inward. Then ensure having exhaust fans at the top of the case and use that to exhaust the hotter air.
Or use a 240/280mm Rad based AIO and place it's Rad at the top of the Case; either having it's two fans in front, or beind the rad, blowing the air towards the top and out the case. Some do push+pull with those as well, but generally under stock clocks shouldn't be needed given the extra size and capacity of a larger Rad of this size. Then have the rear case fan blowing inwards.
The reason I make this points with regards to having what would normally be a rear hot air exhuast fan area on a case be swapped around; is simply because with the use of a liquid cooler on a CPU, u can often end up with a dead/hot-zone around the CPU/VRM/RAM area if you do not use that rear case fan area as a means of bringing cooler air to that area.
From the sounds of what all the OP has said, CyberPower never had it correct, or even close to effective from the start. According the OP, his Rad was setup with 2 fans on it (one on either side of the Rad) but were both facing each other; which is an obvious culprit for those bad temps.
CyberPower PC also have a terrible reputation, I know that and I live in Australia where there are NO CyberPower PC (since in Australia a 12 month warranty on parts and labour is the minimum legal duration).
