First 9.5 mins:

Last 3 mins where I basically just reboot to show BIOS settings:

Long story short here...@1.4V the VRM heatsink is ~37 - 38°C with a ~22°C ambient when the case is closed with no extra fans.
I'm not sure anymore what Temp 3 - 6 are in HWiNFO. It could be the VRM package, or it could be CPU socket or something else. ¯\_(ツ)_/¯

+rep for science.

Temps 3-6 present on asus b350m- variants. No clue.

Nice:thumb:

Those fets at that ambient temp and with that load are in the fields of +/- 92% efficiecy.

How do you like the XB EVO ?

As Yendor said +1 rep for science. thumb.gif

I'll give the videos a look when I get a chance.

I think it's great. It's pretty easy to get at things on the motherboard. Getting at the PSU is a bit of a pain though, but you can take the motherboard tray out without too much effort to make it a little easier.

How did you arrive at that figure?

Still, the temperature of the chokes is unsettling. Why would asus cheap just there on an otherwise good design... dunno.

Anyway, I've seen vrm switching frequency settings for vcore and soc on the bios, messing with the vcore one might produce pleasant results. I wouldn't go above 500khz on the prime though.
post #1487 of 1994
Well I'm not worried about it personally. As others have pointed out it's just a copper coil with a ferrous core in a ceramic case. I wouldn't be surprised if they're good for several hundred °C. It's just heat bleeding into the surrounding circuitry that could be a problem.

For the test, like I say, I wanted to do a setup that your average joe might come across...and I doubt Joe would be messing with switching frequency. I've never even messed with it myself but I'd look into it if I felt it was a problem. I lost the silicon lottery again though anyway (I'm 0 for 3 in the last 6 years), and AMD recommends not going over 1.425V (which doesn't even get me to 3875MHz) so doubt I'll bother going higher than 3800 @ 1.325.

Maybe when Zen 3 hits on the "7nm" node I'll get a new chip and have a reason to drive it hard but who knows?

I can't get rid of mine, I will only change it for something that is not vertical and fits better than the EVO XB. Power supply and plenty of storage are a bit trouble tho.

Yeah the hot swap bays are worthless because the PSU cables are in the way. I have a longer than normal PSU that's not technically supported though so you might be able to use those bays with a smaller one. I knew I was never going to use more than 2 or 3 drives anyway though. For anyone that plans to use more it's not a great option unless you're ok with sticking your SSDs somewhere else and use the 3 main mounts for your HDDs.

It also makes sense to use a VRM water block when you have a loop already and you know it.

I've seen a lot of comments in this thread about needing active airflow to cool VRMs for Ryzen. In fact, people were talking up the Titanium for having the best sink.

I thought you told me to buy that EK block. Maybe that was someone else.

Doing it wrong by cutting out by making use of the superior cooling ability of a water loop that's already there?

Pretty simple, eh? Is that why ASUS released a Sabertooth board with a 40mm VRM cooling fan that blows air the wrong direction (back into the case)? rolleyes.gif

With a hybrid VRM/water block, as has been offered on Intel boards since 2013, one can get even more quiet and even more effective cooling.

The bottom line is that having the option to get a board with feature parity isn't important to you. Being able to take advantage of the loop already paid for isn't important to you. It is to me.
