Is it better to mount fan as intake or exhaust with AIO for VRM better temps ?

MB I/O has different between Z370 Godlike and Z170 Xpower

Z170 Xpower has HDMI output

Z370 Godlike hasn't video output

I prefer that MSI Z370 Godlike is 16+1+1

Why confused? They doubled 6+2 to 12+4 for the CPU vore and iGPU phases, then they used a Primarion digital PWM and some On Semiconductor PowerPAKs for the VCCSA and VCCIO, most vendors use different PWM controller for VCCSA/IO as there aren't many PWM controllers that support 4 different PWM output blocks, most support 2. From my review:

The VRM on this motherboard is in a 12+4+1+1 phase configuration for the VCore, iGPU, VCCSA, and VCCIO. The main PWM is an IR35201, one of the most popular high-end digital PWMs on the market, and it's being used in 6+2 phase mode. Each power stage for the VCCSA and VCCIO is an IR3555 60A PowIRstages.

BTW the NIC difference is because of a special networking tech they have called Killer xTend, it makes your motherboard capable of being a sort of switch/WIFIAP/wifi range extender, and you can also throttle connected device bandwidth in favor of providing more bandwidth to your rig. I assume the price of the board is high because the license is pricey as are the three wired NICs and a single killer wireless NIC.

Should I just get the Maximus X Hero for a 5.2-5.3 binned chip or will the Gaming Pro Carbon be enough?

Binned chip (I'm assuming it's about 1.35v) should be fine on z370 Pro carbon although I think the heatsink is hampered by the plastic covers. I wouldn't push it on AVX2, but for SSE or AVX with maybe -200Mhz or -300MHz offset I believe the power draw will be close enough. All the midrange boards should be capable of ~ 220W with airflow

edit: For example AVX2 is used in x265 and ffmpeg

Yeah I'm not sure what the voltage will be like, probably 1.35 to 1.4. I probably won't be buying for another 2 months or so but I want to get an idea of how much I need to spend for a motherboard that can overclock. I won't use the extra features of the Hero

Depends on the system and configuration.


I was curious in my situation because I have a very large full tower case with a huge amount of space inside. The fans are nearly an inch away from the top of the motherboard, and there's a ton of empty space all around the radiator. With the AIO set to exhaust it can pull a lot of air out of the system without getting much airflow across the VRM heatsink specifically. Switching to an intake would at least blow part of the air directly on the VRM heatsinks, which might improve temps for me by a few degrees.

In a system with less free space such a switch would have less of a benefit. More air would be pulled across the VRM heatsinks in an exhaust configuration so there would be less of a change if it was swapped to an intake configuration. Antsu posted a picture where the fan was about 3mm from the VRM heatsink. Fan orientation wouldn't make much difference in that setup. My fans are closer to 3cm away from the heatsinks and there's more space to draw air in from other directions, so the fan orientation could conceivably have a greater impact for me.

So I am looking at the MSI webiste page for the Z370 Gaming Pro Carbon

https://www.msi.com/Motherboard/Z370-GAMING-PRO-CARBON-AC/Overview

and it says there is a debug LED.

Where??? Am I missing something?

It's not what you think which is why you don't see them.

There are 4 tiny LED lights on the top-right corner of the motherboard. They are marked "EZ Debug LED" and are just above the 24-pin power connector.


But they're pretty much useless, there’s no code reader or onboard power/reset/clear CMOS buttons. I suppose they are there so their tech support might be able to figure out what's wrong when you tell them the blinking pattern.

Got the Hero, fitted the monoblock. Going to report back some numbers when I can.

I don't have any kit for making direct heat and power measurements though, and I'm specifically interested in VRM temps.

Are the VRM sensor readings super hidden or will I be able to view them? Also, can someone suggest kit for making real readings - I'd like to up my game a bit and actually start taking this seriously.

@ aDyerSituation

If you want to be more sure, grab a board on the Siliconlottery QVL.

I'd budget $150-160 (Extreme4/Fatal1ty K6 cost on Newegg). In two months maybe all this early adopter price gouging will end.

Voltage x current = power.

Use hwinfo64 and attempt to verify results with an infrared thermometer at the back of your board (aim it to the back of the board where the VRM heatsinks are).
