Ryzen 5 3600 High Temps with H80i v2

[Fuzzyy]

So 2 weeks ago I upgraded my pc from FX-8350 to R5 3600. I am using the same AIO cooler (Corsair H80i v2) that I used in my FX-8350 build and my temps were around 35-40 degrees celsius on idle, 70-85 on loaded. My Ryzen CPU is idling on 45-52 degrees celsius, 80-85 degrees celsius when doing a cinebench R20 benchmark. It doesn't matter if I crank up my fans to 100%, it still stays at 80-85 when doing a benchmark. Same goes for idle temps, it doesn't drop down from 45 degrees celsius. I might have over-applied my thermal paste, i am using Noctua NT-H1 paste. My AIO is exhausting the hot air in my case (mounted in the back of the case). I have 2 front intake fans, and the top 280 mm fan mounting spots are empty. I tried removing the side panel, removing the top hard covers, but temps didn't go down.

Here are my specs:

ASUS TUF B450 PLUS GAMING

R5 3600(Stock Ghz)

Corsair LPX 16GB Ram

ASUS GTX 760 DirectCU2(Gonna upgrade soon with RX 5700XT)

Thanks for the help!

If you think you may have applied too much paste, try cleaning and re-applying. Aside from that, check the fan header you're using for your pump and make sure it's not running at a low voltage.

I have a hard time with my temps as well. I'm running a Cooler Master ML360 on a 2600X which I know is overkill but it was on sale and fills the space in my case. Try checking your motherboard's reported temps. They seem to be in a closer ballpark of what I would expect. I've read elsewhere of some having Ryzen mis-report their temps and I have to wonder if it contributes to thermal throttling.

 

My Ryzen Master reports 94C but there's no way that it's getting that hot with my setup on Cinebench runs.

It's plugged in CPU_FAN header which I don't think that it runs on low voltage. I might re-apply the paste soon.

I hate to break it to you, but my Ryzen 5 3600 also idles around 40C and 73C under full load with an DEEPCOOL GAMMAXX 400 and Arctic MX-4 paste.

:(((

What software should I use to check the temps?

#1 check the mounting is correct. Not enough or uneven mounting pressure is a common cause of poor thermals.

 

#2 go with a static vcore voltage in the BIOS. Ryzen boards are overly aggressive when on the auto setting. Start with 1.3v and adjust up or down from there, if it crashes in CB R20 notch it up by a 0.01v at a time, if it's stable notch down until it crashes then go back up a couple

I will do number 2 I guess, I checked the mounting and re-applied the thermal paste.

Re-applied thermal paste and nothing changed.

What did the paste look like when you took the cooler off?  Patterns in the paste can tell you about  mounting pressure. 

[xg32]

the "stock" voltage on zen 2 could be too high, consider using a -.05v offset, or even -.1v if stable.

CPU was covered with a thin layer of thermal paste. It had like vein pattern on it or some may call branches of a tree.

Something like this :

I will try that now.

These areas look a little thick indicating maybe its not even pressure. The red looking worse than the yellow. 

 

If you are sure the mounting mechanism is secured correctly it may be that you have a bowed IHS or heat sink cold plate.  Possibly a little of both.  If it's possible try mounting the cooler rotated 90 degrees to see if that makes a difference. . Otherwise you may need to sand the IHS falter.

Okay thanks, will try that.

I've been using HWMonitor for my temps and this seems to be the standard. My motherboard has a sensor to measure the CPU temp itself so I've been confused as to which was best.

I guess TMPIN0 temp is my cpu because it always changes, and it matches with the CPU temp on corsair link software. But I just noticed that they are both wrong, my Ryzen Master app is showing different temperatures

Facing the same problem as you. When I initially installed it with the stock cooler, I was idling around 44c just browsing Google and watching YouTube. Me, being concerned and very impulsive, purchased a Kraken x62. Literally getting the same exact temperatures, if not worse, with the 280mm AIO. I returned it after a day and am starting to settle with the stock cooler temps. Within a week I'm going to order a Hyper 212 Black, or something along the lines of that cooler.

Guys, these CPU's are running at 1.4V ALL the time (Plus spiking when launching chrome etc, which is normal) However, running at 1.4v on idle isn't. Turn on AMD cool 'n quiet in BIOS and your CPU will downclock + use lower voltages when idling.
