I would expect same and worse issus on MSI board, as the VRM looks like a complete overkill. Also my previous experience with MSI was not very good.

AsRock used to have as bad or worse reputation, but when i saw the quality of the build in x399M taichi i gave it a try. The VRM has some specifics (mainly the Prochot switch and only 8+4 connector) , so I will understand that it will not perform as good as the Asus original.

Gigabyte was clearly concerned about the heat caused by the VRM. That itself is not a good sign.

In my opinion, for what it's worth, we need to separate the VRM into two parts: 1) ability to deliver power, and 2) effectiveness of companies' cooling solutions.

As to chips on the motherboard, the taichi uses the exact same components as the Zenith Extreme. You can complain about the 8+4 pin on the taichi, but it shouldn't be an issue outside of extreme over clocking. Now, it may have issues depending on circumstances with the 24 and 32 core chips, but that is more a cooling problem before it is getting power to the VRM.

Now, for cooling solutions, they all suck, just some worse than others. The GB solution seems to have the worst heat dissipation, followed by the taichi. If not for being useless decorative blocks, these companies could have done better. Asus isn't much better in these regards. The MEG creation gets around this by spreading heat to more phases, allowing cooler operation. How I for around this on my taichi is universal water blocks from koolance. With that, my VRM stay roughly between 20-50C, depending on ambient and load, with low 40s being common under load when ambient is in the high 60s F.

But wanted to being up that even well designed VRMs an make a board fall if you don't have proper cooling (hint, hint MB MFRS)!

Those blocks are not just decorative if the board is enclosed in a aircooled case and there is plenty of air flowing around them. But clearly... taking a saw and make some fins out of it would be more effective.

^ Wow I guess the MEG creation is the only one that can deal with 2990WX well

Anything up to 120°C on VRM is still within specs, but it would cause faster aging of VRM. I would recommend to replace thermal pads on AsRock boards before overclocking 2990W, because the cooler mounted to it wasnt getting much hot.

Running any of those systems outside of a PC case, or without proper aiflow is also not a good idea.

incidentally, the cooling of the Mosfets should be judged positively. In series operation, we have carried out a load test of 20 minutes, with no active airflow was placed on the radiator. At the end we were able to read a temperature of 55 ° C of the MOSFETs, 52 ° C for the CPU (Enermax Liqtech 240 @ 670U / min) and 40 ° C for the X399. So there still seems to be a lot of room for maneuver here, especially if you actively activate the coolers.

On my base temps for the GB x399 Aorus xtreem ie web work I get 42 C per Hardware Monitor.
When gaming or folding it runs 70 C.

I am letting AMD do the management of the CPU clocks. In general the web speed runs 3500 MHz and Gaming or Folding runs 3999MHz.

I am running a waterblock on both the CPU and GPU.


I placed a probe on the back of the board and it appears the back of the board runs quite hot.
