Some videos for people who want to reduce vrm temperatures when overclocking the 3900x which this board is not designed to do.
Here are the IR images from the
MSI MPG X570 Gaming Edge WiFi which has the same vrm's.
In some review, the voltage regulators of this motherboard have been brought to the boil with great audience appeal. The practical value of such show interludes (which nevertheless didn’t break anything) is of course far below zero, because who takes the VRM coolers and puts a Ryzen 9 3900X on them at the same time, which is cheerfully beaten through the village with levered out BIOS limits and AVX? Nobody with any sense. But you shouldn’t gloss over the somewhat cheap VRM configuration either, because the fact that MSI saved a lot of money and didn’t use very cost-intensive MOSFETs is a fact.
With only real four phases you can of course easily achieve your goal, but efficiency and high performance OC potential will go a little to your knees if you really sound out the extremes. However, all this is still whining on a quite high level, because with the small graphics cards around 130 watts TDP, strangely enough, nobody gets excited about four or five phases. But somewhere you have to get the money for WiFi and Bluetooth back. MSI is just as little Mother Theresa as all the others. The calculation of such motherboards is similarly scarce with all manufacturers.
As long as one moves within the specifications, this part is however almost to be neglected, but OC is now times explained people’s sport number one. Let’s therefore first look at the front and back of the board with 90 watts of supplied power (BIOS default settings). The hotspots and the somewhat higher waste heat result from the somewhat less favorable power distribution on fewer MOSFETs, which in addition do not combine high and low side as PowerStage in one package, but are discreetly realized and the somewhat lower efficiency of this built-in voltage converter solution. However, the maximum measured 67 °C after approx. 30 minutes full load of CPU and GPU in the closed case is nothing to criticize, especially since the average of all converters is approx. 62 °C (VRM sensor in HWInfo approx. 61 °C).
The backside is significantly cooler, which is due to the rather thick and massive PCB. At least MSI hasn’t saved here, after all. The Doublers / Gate Drivers are still the hottest here, but nothing gets even close to areas to worry about. But the PCB is warmer than the other two competitors. Whereby it remains complaining on a high level.
But what happens if you overclock and the 130 watts are almost 45% above the AMD CPU norm and 25 watts above the 105 watt CPU power of the board? The peak value of one phase rises as a hotspot to almost 84 °C, whereby the average is a good 75 °C (sensor value via HWInfo64 76 °C). But even this is still justifiable, if you consider that even now there is still more than 20 degrees left until the throttling and that the board material only starts to gas out above approx. 100 °C. The temperature of the throttling is about 100 °C. You won’t find any bending problems either.
The backside is clearly cooler with 77 °C and it is actually almost comparatively cool if you take the front side as a comparison.
Interim Conclusion
You have to be honest and point out the disadvantages of the rather simple voltage transformer solution on the MSI board. This is not a limitation of the CPU performance, functionality, stability or lifetime, but only a certain thermal disadvantage, which might lead to inevitable throttling with a Ryzen 9 3900X and permanent wattage of more than 200 watts (Default TDP / TDP 105W) and a fully loaded graphics card. It’s up to the user to decide how relevant this is for him.
So with all three boards you are far away from any sensation when it comes to operation within or slightly above the specifications. If you’re looking for the extreme OC of the big CPUs, you’ll prefer other hardware that was designed for it anyway. But it’s not quite so coincidental that these boards are much more expensive. Surprised?

Concusion
Even though some PR departments (and some media) may think that certain details are sensational, you can still safely rule out any thermal problems as long as the boards are in power consumption ranges for the CPU that the Ryzen 7 3700X can reach as a normal Central European without sinister murder intentions. You really have to be honest in the end and put the price and the target group in relation to the result. And that’s exactly where individual boards don’t cool worse than others, but some cool better than the rest, because nowhere is anything broken. So it’s always a question of perspective and marketing that is paid to produce arguments.
And you won’t get more than 130 watts out of the Ryzen 7 3700X, as long as you don’t lever out all mechanisms in the BIOS and try extreme OC with supposed monster coolers and brutal voltage increase. Then, with a bit of good will, you can get everything sorted out, even the throttling. But what is really close to my heart is the fact that a reviewer does not forget his own responsibility towards the consumers in all the understandable hunting of quotas and ranges. For it is precisely these cases with a different cooling configuration and without any reference to reality that lead to uncertainty that benefits no one.
I think it makes much more sense for me as a customer to know that nothing burns up, as long as I stick to the very broad possibilities of the OC, use a CPU that is also reasonable in price for the board and also find out whether my headset performs at least to some extent at which plug – or not. In addition, a missing 20-pin motherboard connector for e.g. the USB 3.1 cable of the front panel is much more annoying if you have to buy something else instead. The potential chance of a fooling around with improper overclocking seems quite silly.
If you are looking for gaming benchmarks, you will intentionally not find what you are looking for here. All boards perform absolutely identical within possible measuring tolerances, which also applies to the maximum possible clock rates. Those who overclock manually will not notice the different efficiency of the power supply, because the differences are rather marginal and also not within the limits of reproducible results. Only the temperatures are different and the slight voltage regulator losses then affect the EPS. Only those who use PBO for overclocking alone and maintain the strict limitation of the wattage to 90 watts will perhaps sporadically have 25 MHz less, but this is relativized when CPU cooling comes into play. You can lose a lot more if the CPU gets too hot.

I can’t understand all the media excitement about this board. The voltage regulators are not world champions, but they do what they have to do. Thermally everything still works fine, so you should really stay on the ground. These savings, which don’t interrupt the function in normal use, give the financial manager more leeway for additional features. And so it comes as the only board of this price class already with integrated WLAN module (Intel) and Bluetooth 4.2 to the customer.
So the connectivity fanatic is well served here. Apart from that there are no further highs and lows, even if the board still touches it best haptically, which is probably also due to the relatively high weight. Ok, I missed the 20-pin for my Type-C front panel.
