Utter noob with cooling - fans being volatile
- Thread starter Lovejoy!
- Start date
have done this now. not really seeing any differences on the ryzen balanced/windows balanced power plans unfortunately. my cpu does seem to have a idle voltage of around 1.25v which when not under load seems like a lot? also explains the high heat?
not sure on next steps. don't know whether i've just been unlucky in the lottery, or whether i need to further cool the system with an AIO or good air cooler? yeah, bit deflated with it really
If everything is at stock BIOS settings (i.e. no manual overclocks on anything and all voltages also set to auto), then Vcore is supposed to idle at <1.0V:have done this now. not really seeing any differences on the ryzen balanced/windows balanced power plans unfortunately. my cpu does seem to have a idle voltage of around 1.25v which when not under load seems like a lot? also explains the high heat?

What monitoring software are you using? Make sure you don't have more than one monitoring software open at the same time as they can conflict with each other (e.g. HWiNFO, Ryzen Master, CPU-Z, Corsair iCUE, etc).
Are there any processes hogging resources in the background, preventing the system from truly idling? Maybe you might want to try a clean Windows installation and also installing latest Windows updates. Remember to backup all important data first though.
Depends whether the temperatures and noise are ok under load.

If your case fans are set to follow the CPU temp they will rev up and down when the CPU temp increases and decreases. That drives me absolutely insane even with quiet fans and is the reason why I always set the case fans to follow System Temp so the case fans increase and decrease much slower in line with the temp of your system.
This also means that when your GPU starts to heat up the case the case fans will follow, on my old Gigabyte board I could the default curves as they worked well, on my MSI board I had to go custom as the defaults made no sense at all for System Temp

that's a fair point, i'll try that too. is the risk there though that you'll get the CPU running too hot and throttling without the fans being able to counteract it quick enough?
my overriding problem is that i just expect these things to work without much effort which is just naive

Yeah, might be worth getting an after-market cooler if you'll often be putting the system under similar loads. If it's rare that the system will reach such temperatures and noise levels, then stock cooler may still be fine.
Something like the Scythe SCMG-5100 Mugen 5 Rev.B CPU Cooler is good value for money.
The Ryzen ones are mediocre, but worth trying to see if they're sufficient for each person's own needs.

No because the CPU cooler is still cooling the CPU according to the CPU temp as long as it gets some air from the case fans it can do this fine. Its how I've had all of my systems set up anyway and never had a problem
i have a bit of a rgb light thing going on at the moment. is there something rgb friendly that i can install. was looking at an AIO really (don't mind spending the money) but not sure what's considered the best.
so, restored bios settings to defaults, did a clean install of windows and only installed chipset drivers directly from AMD and the CPU-Z. was getting 0.2/3/4v at idle, which is nice.
i've also changed the case fans to react to the system temp rather than CPU, so we'll see how that goes. they're ramping up a bit but i've not set the curve at all so...
but yes, i think upgrading from the stock cooler might be the next step. any further recommendations would be lovely.
thanks guys.
Yes, result!
This one has very good price to performance:but yes, i think upgrading from the stock cooler might be the next step. any further recommendations would be lovely.
Scythe SCMG-5100 Mugen 5 Rev.B CPU Cooler= £42.95
If you want to go cheaper, then you could consider something like this plus the additional AM4 mounting kit:
Alpenfohn Brocken 2 PCGH Edition Dual Fan CPU Cooler - 140 mm= £23.99
Alpenfohn AM4 Mounting Kit for Brocken Coolers= £2.99
But this one is bulkier and doesn't come with PWM fans.
Any mid-level tower cooler will cool better than stock coolers. Towers push heated exhaust back and out of case while drawing cool air from front intakes in. Stock flat coolers draw air from above them down in where it hits mobo turning out, hitting RAM, GPU, etc. turning up sides of cooler and is drawn back into it's own fan .. all this means it is using air being pre-heated by it's own exhaust. You might find the below link to basic giude to case airflow and how to optimize it of interest:

when you go into the BIOS what is the CPU voltage at? I have been reading all day that Ryzen and current BIOS's are screwed and CPU sits around 1.4v when in idle you may need to manally set your voltages. This might be why you are hearing things "rev" up when doing basic tasks.
