VRM Temps High?

[Apollo Refugio]

I am running 5 GHz @ 1.33 volts and my package temperatures are fine, but my VRM temps are quite toasty. I searched online and I'm getting VRM temps are fine at 120 C while others say 85C is max. I have a Gigabyte Z390 UD motherboard, so I'm not sure if this is an issue. Are my VRM temperatures fine (VRM MOS) ?

That's quite high. 

 

You could try getting some active cooling on the VRM to see if that helps

What is good active VRM solutions? I cannot find any.

Get a 120mm fan and point it at it

 

Are you using an AIO?

I am using a 360mm AIO.

kinda figured. Most people I see with high VRM temps tend to be on AIOs.

 

Is yours oriented as front intake? if so, it's probably heating up all the intake air, and blowing a bunch of CPU-heated air over your motherboard/GPU.

 

Keep in mind the radiator is also acting as resistance for airflow.

 

If you have rear and top fans, are they oriented as exhaust?

 

As far as normal operating temperature, the components are designed to run at a maximum of 120 or 125c (forget which), but that doesn't mean you want them to be that hot. They are rated for lifespan and that is at number of hours at xyz temperature. So the hotter your power delivery components are the shorter that lifespan is and increases chances of failures.

you can try to mount a 80mm fan on the back of the mobo to blow some air on the VMRs. watch some guides about it.

I have the 360mm fan as intakes. and i have 3 exhausts fans at the top that are 120mm each. Okay, Thanks!

I was gaming on valorant and my VRMs were at 56 C max. is that fine? im not always benchmarking so this is fine right?

more than fine. if you never encounter those scenarios where it's over 100 then don't worry.

 

some games i play make my CPU/VRM much hotter than others though, so keep an eye out. But if 107 is the highest you ever see in a synthetic test you will never do, it's probably okay.

Although 107c may seem high relative to your CPU temps, it's really not that bad for mosfets. CPU's are exponentially more sensitive than mosfets and can be damaged at about 100c, while mosfets typically can go over 110c without an issue, though you should always seek lower temps. As others have mentioned, getting airflow to your VRM is your best bet.
