What are good VRM temps for longevity?

[T_Dawg]

Hi everyone, first post on the LTT foums

 

I just recently finished my second PC build ever with a Ryzen 1600X on a MSI B350 Tomahawk mobo. As I'm writing this I'm stress testing an overclock @4.0GHz, 1.35V in Prime95 and my motherboard temps are in the 90s. Overclocking is something pretty new to me but I'm pretty sure those aren't very good temperatures.

 

 I'm using the NZXT H440 case as well as the corsair H100i v2 AIO cooler. Front mounted rad on the bottom two fans and one of the included fnv2 fans for the 3rd front mounted fan, one 140mm rear exhaust and two 120mm top exhausts.

 

What are  the highest safe/good VRM temps for longevity while running Prime95 blend test, whats the max you'd be comfortable with? Thanks.

This is between "OK" and "burn your house down".

Capacitors are 105°C, so as long as you stay under that, it should be fine.

I'd buy a small 80/60mm fan and put it on the VRM "heatsink", so you have some cooling.

Please stop

Also what are you reading the temps with?

Just shove a fan over the VRM and you should be fine.

Laser Temp Gun would be nice, not sure how accurate a cheap motherboard's temp readings are

 

if you touch your VRM after a few benchmark runs is it pretty hot to the touch?

Yes, the one on the left felt like I briefly dipped my finger in hot coffee. The one on the top is just a little warm, no pain. This was before I stopped Prime95 though.

Just shove a fan over it in any event, especially since they aren't real heatsinks like this board, or even the ASrock Pro 4

Okay, thank you! But just to be clear, around what temps do you consider to be unacceptable for general OCing?

Until it makes you OC unstable, but you want your temps as low as you can go for longevity of the motherboard always.

How's sub 30c?  (Heavy breathing while using monoblock on a 12 phase intensifies)

VRM temps below 80C is a good thing i mean you have to worry more about the capacitors temps then the VRM.

Sorry to resurrect a thread, but shoving a fan over the VRMs is the right idea. I had a Ryzen 9 3900x build with a board that didn't really have sufficient VRMs the temps were over 100C was worried how long it would live. But then realized a duct or shroud put over the exhaust fan would force air to flow over the VRMs. I searched on ebay found a plastic VRM cooling duct that worked out well lowered the temps to below 80C.
