FX 8350 CPU core temperature spikes on Windows 10 Pro

[MBK1989]

Hi,

Last month I upgraded my OS from Windows 7 Ultimate to Windows 10 Pro. Everything worked great but I experienced some aggressive core temp spikes in almost every games. For example, while playing NBA 2K16 on Win 7, my max core temp is 40 C. However on Win 10, it was 47 C (with similar CPU usage!).

I was monitoring my core temps with MSI Afterburner while gaming and noticed temp spikes. To be more specific, while playing games, core temp was 30-35 C but it spiked to 45-50 C in a second than goes back to 30-35. In Win 7, I also experience spikes but not that aggresive. Because of this problem I reverted back to Win 7 (thats why I used past tense to describe the problem 😀). Do you guys have the same spikes when upgraded/clean installed to Windows 10? Please do not recommend to clean install as I already tried it. If I solve this problem, I will use Windows 10 again.

PS1: Gaming perfomance, CPU usage and GPU temps were the same with Win 7. Only cpu core temps were different.

PS2: Overall CPU core and package temps were similar with Windows 7 but core temp spikes were way higher than Win 7.

Specs:
CPU: FX 8350 @ stock
GPU: R9 380X Nitro @ stock
MOBO: GA-970-ud3p
CPU Cooler: Corsair H80i
PSU: High Power Astro Lite 750W 80+ Gold

Win 10 exploits hardware better than Win 7, so, if your PC is old, then try

1. Putting good thermal paste
or
2. Get the III party cooler

Thanks for the reply. I have Corsair H80i liquid cooler and thermal paste is newly applied. As I said, core temp spikes are way higher even in same cpu usage. So maybe it is related with how Windows 10 manages core voltages?

Windows will not alter nay voltages but mobo do, so, go to BIOS and check what voltages are going to CPU and keep them in recommended range,

Even win 10 gets more CPU power, voltage should sustain at some level, it should not raise with good CPU Cooler.

So may be you are getting false temp number
Can you install CPU core temp tool and see the temperature of cores and post here, to confirm

(And sensors cannot be wrong because you already told that, on Win7, the temp will be in normal range)

I have an FX 6350 and I have been using win 10 for several months and never experienced anything like this. At idle with two tabs open in chrome my cpu hovers around 0-4% usage. And stays at between 30-32c.

I think you are using your cpu with OC which means your Turbo Core is disabled. I am pretty sure turbo core clock causes these spikes as it bumps the core voltages. I am using my FX 8350 @ stock clocks with turbo core enabled which causes spikes. But as I said the spikes are way higher in Windows 10. Thanks for the reply btw.

Edit: Check your Core Temps not package temp. I am pretty sure you will notice spikes too when you open any apps. My package temp is also stable.

Yeah I know that voltages are related to BIOS but power management settings can be changed in Windows settings. Anyway, as I checked voltage range is the same with Win 7 and did not change any settings in BIOS when upgraded to Windows 10. Maybe as you said, as Windows 10 gets more CPU power it uses Turbo Core feature of my cpu better that causes voltage bumps and higher temperature spikes.

Package temp is the core temp as recorded by the cpu, core temp if your using hwmonitor or similar is socket temp recorded by the motherboard. No i don't get spikes in package temp when I open apps unless its a resource heavy app like a game or something, also package temp is notoriously inaccurate at lower temps it becomes somewhat accurate when your cpu reaches 40c or so. I do not have turbo core enabled.

Yes you are right, i mean socket temp. Anyway, as I said the reason could be turbo core as it increases core voltages to the max in a very short time. However, higher temp spikes in similar cpu usage and the same games doesn't sound logical as only difference is OS.

So, any other recommandations to solve temp spike issues? Can you guys also explain how Windows 10 uses more CPU power than Windows 7?
