No. 1.4v is safe for 2nd gen Ryzen, not 1.45v. 1st gen Ryzen safe max was 1.425v.....................................1.45v is ok for a bit of benching but defo not for any sort a 24/7 running.........................unless you is running under Phase ?
Only for short bursts. AMD have said that 1.5V+ is fine at stock because the chip only spends very short periods at those voltages, only when it has thermal headroom and only when just a couple of cores are loaded. The safe all-core voltage for 24/7 use is much lower. I don't know about official sources for the exact cutoff, but Buildzoid has said that you want to stay under 1.4V when overclocking manually.
It's irrelevant how often it hits that voltage really - only for how long and how hot it gets in the process. There really aren't many common desktop workloads where it's going to hit those voltages often, and the CPU will automatically ramp down both voltage and clock speed once it's reached what it considers a safe limit (in terms of time or thermals). Spikes to 1.5V+ are usually over inside one update in a program like HWiNFO64 (2000ms by default), and only occur under very light loads when only using a core or two. Anything heavier and both clock speed and voltage come tumbling down. On the previous MSI board I had this 2700X in, voltage dropped all the way down to ~1.3V with all cores loaded, with a boost of ~3.95GHz, which is probably about right for bone stock. On the Crosshair VI I replaced it with, I'm getting ~4.15GHz all-core boost at ~1.375V under full load with the 'Performance Enhancer' level two setting and no other manual tweaking. The single-core boost on both boards was the same 4.35GHz limit with voltages bursting to 1.5V+ during those short periods. I've left HWiNFO64 open for hours at a time whilst just using my PC for desktop work and some gaming, and the averaged voltage over the whole period is always somewhere between 1V and 1.1V, so on average the CPU is seeing very low voltage levels in common desktop usage over a long period of time.
If it's B Die like you say then it shouldn't be the memory at fault here... post a photo of your settings
There should be a setting in your BIOS somewhere to control fan ramp up/down time. Increasing that a bit should stop the fan spinning up every time the temperature briefly spikes. Even my Noctua NH-U14S exhibits that behaviour if I don't increase ramp up time a bit.While the supplied 2700x cooler is half decent for me it keeps revving up and down like it's on the edge of the required temp level and has to keep speeding up to pull the temperature back down which can be annoying, that's with a Corsair C70 case. I just ordered a Be Quiet Dark Rock Pro 3 to replace it, I've wanted to get a proper high end air cooler for a while so now I have this one should last longer than me.

Yeah i also can hear the fan revving up and down all over the place
I agree with you about the stock cooler that comes with the processor as half decent indeed.
I have a xigmatek pc case so you are not the only person to hear the fan going up and down like a yoo yoo.
