If it helps, I have the 3950X and my Noctua DH-15S keeps it decently under control. 35 degrees celcius 'idle' with random spikes up to 40ish, during gaming it doesnt go above 60, during handbrake it sits somewhere between 60-70 (65-72 under intense handbrake loads). Never seen it above 72. One cinebench run ramps it up to 62.

Ahhh I see. Thanks, some more to think about.

That's quite informative. If I gather correctly, PBO is just press on and off when I want better multi-core performance? (if possible on my chip/cooling situation) Is PBO purely automatic or do I Indeed have to tweak some other settings to get it to sit and play nicely? (and therefore make sure I go and understand those setting first) My CPU seems pretty cool most of the time - the 70ish degrees celcius using handbrake is the highest I have seen it go. Its around 45-50 dC modelling and 50-55 dC playing Doom Eternal. 35-40 dC 'idle'. Using Noctua DH15s 2X fans Thanks!

@Rem0o @Adrenalina I realise you just asked for the scripts to move, but... Could such a script be used to link PC power profile changes to the change in fan speed profile? (e.g, silent fan profile that switches to low power profile with lower max CPU etc.)

Thanks, gives me some more context at least to start reading more.

From my sporadic reading so far.. PBO is the easyish Ryzen overclocking mechanism right? I have yet to delve deep enough into this to know if I want to give any kind of overclocking a go and if its even worth it.

@emosun Thank you! Downloaded and tried Cinebench and it hits 100% fine.

@samcool55 @emosun I have HWiNFO64 and found the VR MOS - assuming this is then VRM. Temps look okay I guess? Googling says dont worry below 70. Were you expecting this as the issue or a higher temp for VRM temps to be the problem?

Thanks! Yeah the new CPU does it about 60-80 mins quicker for similar sized video. MB is MSI MPG X570 GAMING PLUS.

Hi, quite new here and very new to PC building in general (used to buying laptops), This is more of a 'please help me not go crazy with worry' thread. Been trying to read up on it, but its quite a daunting topic to try and find your way in to. I recently upgraded from 3800X to 3950X to improve my modelling/video encoding pace. On my 3800X running the SHQ preset in Handbrake maxed my CPU (all threads) 100% in task manager and stayed at 100% the whole time it ran. Trying this with the 3950X it jumps around from 55-90% task manager usage and in Ryzen Master I get this: Loads of the the limits in Ryzen Master being hit 100%. I don't have a screenshot for the old CPU but so no comparison I'm afraid. I am just wondering if something is going badly wrong here, or if its expected behaviour as it never seems to hit 100% in task manager for handbrake. It once hit 91% for about 2 seconds (4.01Ghz) then drops back down, it mostly stays around 60-70%. It does reach 100% if I ray trace in PyMol (biological modelling software), but it also doesnt even turn my fans up doing that, and sits at 4.20Ghz, happily not caring. If theres 1% chance of an issue, happy to start providing more details if needed. But if this is likely just a quirk of the software not actually needing to stress out the 3950x as much as the 3900X, then great!

Works fine for me. Thanks again!

Hi, Signed up to discuss this piece of software. Really brilliant idea, thanks for taking the time to write and release it. I have been searching for a few days now for something like this, mainly because the MSI Dragon Center software will only let me set one custom fan profile. The default profiles don't fit any of my needs, so I have to spent 10 mins editing the fan curves before I change what I am doing. Not helpful. I downloaded this and gave it a go. As I said, it looks like it will fit my needs perfectly. Unfortunately it doesn't seem to be working as intended, perhaps there is something I have not done correctly? The issues at the moment: When I start the software it sees all the temps, recognises my curve and adjusts fan speed. But, the temperatures it shows then fail to update (I can see the CPU temp changing in RYZEN MASTER still), and fan speeds remain unchanged. The only way to get the software to recognise the temperature changes is to quit FanControl and restart it. FanControl sees my two GPU fans but doesn't seem to recognise the fan speed. It was recording it once, when it was at full speed, but it doesnt record the speed ever since. When the software is running, MSI afterburner and HWINFO64 both hang. I thought this might be to do with competing fan control actions, but I turned off MSI afterburner fan control and it made no difference. I am using a MSI X570 Gaming Plus M/B, with Ryzen 3800X CPU and 2080 Super GPU. I have tried this with and without MSI Dragon Center running, and I also tried running where I disabled everything I could find in task manager related to MSI/Dragon Center. I hope someone might have an idea to help, as I have no idea why it isn't working. Thanks!
