High Ryzen 3600 temps on MSI X470 Gaming Plus

[MatteRB26]

Hi, I recently got my new Ryzen build going, and ran a quick AIDA64 test and the boost kicked in to 4.2ghz, but the temps immediately hit 90C. This reduced the clock speeds to 4ghz, but still 80C. The speeds would then fluctuate between 3.8-4Ghz while hovering around 80C.

I've only run WoW so far, and had 51C running at 30% CPU usage which seems okay, but the 80-90C constant temps seems a bit high to me?

I'm using the stock cooler with Thermal Grizzly Kryonaut, but before I consider a new cooler, I want to make sure there's no weird settings to check in my BIOS (I'm running latest as of today), or if I should consider undervolting (how do I undervolt? Never had to change voltages before).

I'm coming from an overclock 3570k with a CM Hyper 212 Evo that could keep it steady at 4.4ghz under 65C at all times, so 80-90 feels very high. The monitored temps are coming from both MSI Afterburner and Ryzen Master.

yea, those temps do seem high. I dont use the stock-cooler but at 90c+ ill be a little worried. Temps like that could be caused by bad thermal-paste application (it would have to be bad, which you probably didnt do), high voltages from your MB or poor cooler (surely the stock cooler isnt that bad?)... or a combination of things, like a weak/average cooler with high voltages. Use something like Ryzen master to see what the stock voltage is.

It doesnt help much, but im using a 3900x (stock) on a 280mm AIO, and peak at around 60ish. I would have thought a 3600 would be easier to cool than 3900x, although AIO would help. Sorry I cant help more, maybe someone else can

I'm fairly sure I remember the voltages being around 1.3-1.35v. I'll check tomorrow.

It could be the paste because that cooler was a ...... to install so the cooler moved about a lot during installation. Maybe I'll redo it as well now I have more just to be sure!

So... Update: I tried undervolting and set a -0.05v offset. By default it was running around 1.4v to 1.45v. since applying the offset, it only boosts to 4ghz, but it runs at 60C!!

From here I'll try incrementing the voltage to see if I can hit 4.2ghz at a sensible temperature.

I get better temps on mine running a 4.2ghz all core OC @ 1.325v then stock and its also 100 points up in cinebench.

Also a really cheap option for a cooler is the wraith max on OCUK for £12.95, it's pretty much the same as the wraith prism which I have on my 3600 and it keeps temps below 70c at max load.

What motherboard have you got? I'm finding my Ryzen so much harder to get right than my old i5... My 3570k went straight to 4.4ghz with stock voltage. Google is just confusing me the more I research with the Ryzen...
