ASUS ROG STRIX Z390-F Gaming VRM Temperature + A VRM

[Mugen]

Hi,

I just searched the whole internet to find any info about VRM temperature on (idle + OC) mode and is it 400 A VRM or 500 A VRM etc. but I couldn't find any credible info about it.

P.S. I am planning to get i7-9700K with it and maybe will OC it.

Thanks to all.

asus uses good vrm mosfets that will throttle when hot
if the board has vrm heatsinks it will be fine as long as there is airflow over them

if using a clc or water loop, mount a fan over the cpu block to keep airflow over the vrm hatsnks

Not a whole lot exists for many motherboards for specific VRM measurements; for mine, I actually stuck in a thermistor sensor probe and measure the temperature in real time. (I also do this for ram and other locations that are prone to hotspots.)

My advice is to if you are worried about temperatures, ensure your cooling strategy will include highly variable peaks if you are just not comfortable with what people have reported. You may be forging ahead into unknown territory.

To that end, maybe get blower or a fan to mount over the VRM, if you are not directly intending to replace the VRM heatsink with something custom. I've industrial velcro'd a 40mm fan over my VRM, which actually is water cooled. However, the components around the VRM are not directly benetitting from this, and the airflow movement helps a great deal in reducing the temperature disparity in the area.

I also added a number of small copper and aluminum heatsinks (tall and short, mulipronged and finned, depending on the situation and my airflow orientation). These can help, too.

But I have the same issue. There's no direct answer I could find for what works best, so I had to figure out some of it myself. It'll change, too, if you upgrade the CPU later to something with a higher TDP, so keep that in mind.

ds18b20 temps sensors are dirt cheap and super easy to use with an arduino
you can use many in parallel for multiple reads

https://lastminuteengineers.com/multiple-ds18b20-arduino-tutorial/

from there you can make a java script to do whatever you want

or pick up a display and make it all one seperate unit, for use in the case
the 1.3in oled i2c (white or blue, multicolor is just colored sections) are easy to wire up and nice and bright

I didn't get MB yet but i am planning to get it with that CPU i mentioned before, that's why i asked about VRM temp etc.

i have not seen any mobos with vrm temp sensors that can be read by software
cpu socket sensors are common (temp sensor under the cpu socket)

unless you do hardcore overclocking, there is no need to pay to much attention to VRM. Just dont take the cheapest board you can get

The thing is that “ASUS ROG STRIX Z390-F Gaming” is on a cashback promotion right now, that's why I'm tempted to buy it.

Having a 9700k and the asus z390-f. Using a dark rock pro 4. Highest temps i got at Metro Exodus after 5/6 hours of playing: 65°C @ 4,9 Ghz.
You cant really go wrong with a good asus motherbord.

May I ask, how long you have been using this motherboard?

most pc hardware has rebates of some form

Bought and build everything at the beginning of march this year.

Is the PCI-E slot's lock/retention clip is made of low quality materials?because some people have reported that it got broken with them.

Same material as i always had on mb's. Tbh, you must be really really dumbor clumsy to break this thing in general

Hahahaha, i just decided to go with Gigabyte Z390 AORUS PRO because it got better and high quality VRMs.

Thanks to all for their info, wishing a wonderful day to all.
