MSI MPG X570 GAMING EDGE WIFI owners - are 100deg c VRM temps an issue?

Hey folks

Got a new OCUK build a month or so ago with a MPG X570 GAMING EDGE WIFI motherboard and everything is going well.

Thing is Ive now seen a lot of videos and a few reviews where the VRM temps on these boards sit at 100 degrees C when running and reviewers have pointed this out as an issue for longevity, esp when rendering which is what Im using the system for.

https://www.kitguru.net/components/...0-vrm-temperature-analysis-luke-deep-dive/10/

One example of the info on the temps.

Ive got it with the 3950x but not overclocked so just wondering if I should worry about this or if its likely to cause issues a year or two down the line (and Im not wanting to buy another system or upgrade having dropped £3000+ on this one).

Would somehow jerry rigging an additional smaller fan on or near the VRM heatsinks be an idea?

Thanks for any advice folks!

would have gone for Aorus Ultra or master if you had the cash or MSI Unify .

In theory, most MOSFETs can handle 120c of heat, but vendors may set throttling of CPU at lower temps for mobos lifespan.

Some MOSFETs can take 150c of heat naked for extended periods of time but again board vendors wouldn't allow this

Push all cores to 4.3ghz and vrm will shoot up

No offence but 3 grand plus
I would have bought a better board
I would slap a couple of those tiny noctua fans on if it was mine
Have heard for small fans they aren't irritatingly loud like most small high rpm fans

I asked OCUK to build a system and thats what they suggested buddy.

I'll look into the small fan ideas as that was my thinking

Thanks

Thats good info thanks

100c isn't actually that hot for a mosfet. I'd say the worst that is going to happen is it might throttle or be unstable if you OC it. Looks like MSI have put just enough on the board to handle the 3950x, with no real headroom.

I've never actually seen anything that really shows vrm temps actually affect the lifetime, and the rated lifetime of these things is generally crazy long, so I really doubt it matters as long as it stays below 125c.

I'd be more worried if there were other more temperature sensitive things next to the mosfets, but looking at the board that doesn't seem to be the case.

Fair enough the board wasn't your choice

And pretty sure ocuk have those little noctuas there's couple different sizes and thicknesses
Think 60mm is the bigger the other may be 40mm
As said 100c might be ok
But wouldn't be keen on it personally

Thanks for the indepth answer bud, much appreciated! Ive run the same mobo monitoring software they use and for 20 mins it hits about 80 degrees so Im a bit happier but will probably get a couple of extra smaller fans just for peace of mind as I want the system to last a good number of years.

Im going to get them, the last system I had running for 8 years (3770k at 4.5) and this one I expect to run for at least 5 years unless we see big strides in performance gain again.

Thanks for the help buddy

High temperatures dramatically shorten life of VRM's capacitors.
Even if less sensitive than liquid electrolyte caps, polymer caps aren't immune to high temps.

You're welcome mate

I have the X570 Carbon which is also considered to have terrible VRM cooling. I ran folding at home for a few days with my 3800X (stock) and max VRM temp never reached 70C. (Case has good cooling)

3800X in a well ventilated case is not worst-case, but it has the same TDP as your 3950X.

Wouldn't oc to 4.3ghz all cores it higher. Just believe it to do its own auto boost

Do you actually just sit there running an Aida CPU stress test 24/7 though?

In "real world" loads, the CPU is unlikely to completely maxed all of the time, so unlikely the VRMs are going to run at high temp for a sustained period of time.

Check what temperatures you are actually reaching, whilst running a "real" workload e.g. gaming, video editing or whatever you normally do, and then if it's too high you can look to improve it.
