[SOLVED] Do better MOBOs regulate temperature more carefully?

[remywang]

I'm new to hardwares, so this might be an obvious question and I hope you forgive me. I just "upgraded" to the old X370 Crosshair VI Hero from my new albeit barebones ASRock B450 Pro4. However some things became noticeably slower, for example rendering bloated websites like slack or doing heavy compilation. But I also noticed that the CPU temp now never goes up above 60, like not a single degree. On B450 the temp easily shoots up above 70 when I browse in Firefox. I'm guessing that B450 doesn't slow the CPU down even if the temp's high, but X370 is being more careful and keeps it at bay below 60? Or is there something else that's holding the CPU back?

The Mobo has no impact on your temps, that is your cooling solution. Did you apply thermal paste and check that the cooler is correctly seated with even pressure?

On things being slower did you enable XMP/DOCP in Bios of the 450 for your RAM to run at the correct speed, is your HDD/SDD connected to the correct slot, is it set correctly in BIOs? in BIOS?

This may help to get more from your PC.... it uses an Asrock AM4 board but as I don't know your full specs use it as a general guide not as a 1-1 implementation....

A motherboard may have different fan curves as default. The X370 might be more aggressive and the B450 default might be for quiet.
Fan curves and built-in heatsinks is all the motherboard contributes to cooling.

Did you install Windows after changing motherboard?

Some details to clear things up:

• I'm migrating from B450 to X370
• System:
  • Crosshair VI Hero WIFI-AC X370
  • Graphics: gigabyte 1030 silent low profile
  • CPU: Ryzen 5 3600
  • RAM: ripjaws v series 16gb DDR4 3200
  • SSD: WD Black SN750 NVMe
  • Cooling: Nofan cr-80eh Fanless cooler

I'm not too worried about the temps right now as I have a new cooler on the way. Right now I just want to get the performance fixed regardless of temps.

did you enable XMP/DOCP in Bios

This helped, things got a bit faster but still slower than B450.

is your HDD/SDD connected to the correct slot, is it set correctly in BIOs? in BIOS?

Check, there's only one slot and I believe the default setting works fine.

A motherboard may have different fan curves as default

The system is fanless so I can eliminate this as well.

Did you install Windows after changing motherboard?

I don't use windows. I'm on gentoo linux and it runs fine albeit a bit slow.

Also, reason for the migration: I'm perfectly happy with the performance on B450, but the temps were a bit high. So I got the best fanless cooler from nofan which is the CR-95C. But the cooler has AM3 mounts, so I had to get the Crosshair VI which has holes for both AM4 and AM3. So from the migration itself I'm not trying to get more performance, just better temps. But ATM the performance on X370 is even worse than on B450.

The VRM temperatures will vary between motherboards, but that shouldn't affect your CPU temperature. Plus it is only really an issue for the very high core count CPUs
