Vrms overheating i think.

[Giannak]

The VRMS on my motherboard appear to be overheating, at idle, they run at about 75C and when i ran cinebench, the got past 95C. I tryed touching the VRM heatsink on my board and it felt like i was touching an iron! is this a problem??

 

My motherboard is MSI B350m Pro-Vdh and my cpu 9is Ryzen 9 3900x.

VRMs are safe up until about 100C, so 95C in Cinebench is about the top end of "safe", but the problem is most motherboards will run their VRM up until they get to that point, then they'll throttle the CPU to keep them from blowing up, resulting in worse CPU performance. Your system is likely running into that point, called "power throttling," that motherboard was just never designed to handle the power consumption that a 3900X can output. Compare your benchmark scores to review numbers, if it's significantly lower I'd at least put a fan on the VRM (that's likely necessary no matter what), and if that can't help keep the VRM from hitting TJMax and lowering clock speeds to protect itself, it's a good idea to get a new motherboard.

A 3900X will push the VRMs on that chipset to its limit. Do you have fans on top of the motherboard pushing air out? If not you may want to add some. If the temps stay at around 75C while gaming, there is nothing to worry about. If you were to do more cpu heavy tasks all the time live encoding, rendering etc. on all cores, getting a motherboard with more VRM headroom would be best. For now, don't worry but make sure you have decent airflow over the motherboard.

my case has no airflow in the front or top:(

What case do you have ?

inwin 301(i didnt pick it, bought the whole pc off ebay)

You should be able to fit 2x 120 mm fans in the front and or at the bottom, depending on the size of your gpu.

What’s the vrm temp called in hwinfo is it mos ? 

[Mark Kaine]

i dont think this motherboard is suitable for that cpu lol...

great little case!

 

 

still you need a better mobo, b550 or x570.

this is incorrect though,  its open on the front / side thats still good enough ... do you not have any fans in your case? 2 front intakes,  1 rear exhaust is definitely mandatory in that case!

 

my temps are cpu 85c max, gpu 72c max, but usually its more like cpu 61c, gpu 60c (while playing games, etc)

the thing about the inwin 301 is its so short, its just like a high end wind tunnel lol, need definitely strong intake fans (i got noctuas) and strong rear fan, also get this, when I turn off my psu fan (psu is on top) the case heats up at least 10c, if not more, so even the psu fan is kinda mandatory as exhaust for this case....

 

im not saying it's great airflow case, but at least average *if* you set up your fans properly, etc 

 

ps: whats useless is bottom fans... they bring about 1c less... so useless... (i don't use fans in the bottom...) i think the bottom is meant for a radiator,  though ultimately i think this case isnt meant for watercooling at all... u cant fit a 360 radiator for example (i think not...)

everything is blocked off becuase i have power supply cables crammed everywhere and i cant even get the back panel closed usally becuase i have a non modular psu.

all 3 fans in my case are very low airflow and they only go to 1100 rpm. even when my hand is right over the fans i still cant feel the airflow. Noctua fans are way to expensive.

there are cheaper good fans too... (forgot the name sorry)

but noctuas are 14 each, still kinda ok imo considering what some worse rgb ones cost (60)

i think i remembered, i think they're called arctic p12, $4.50 a piece... 

 

but tbh, its probably not gonna help, the problem is the motherboard... its not good enough for a 3900x...
