AMD Ryzen 7 3700x running way too hot

[VibeChecker]

I recently changed the motherboard of my prebuilt pc along with adding an m.2 ssd and some new 3000 mhz ram and so I had to basically un-build and re-build my whole PC. The prebuilt pc came with a crappy a320m motherboard and I changed it to a TUF GAMING B550M-PLUS. I removed the old thermal paste and applied some corsair paste (I double-checked whether the paste was spread evenly across the CPU before putting the stock wraith prism cooler back into place). One thing I noticed is that for some reason the wraith prism cooler is slightly tilted/rotated to one side (very slightly though, you'd have to be looking pretty hard to notice it).

So basically the issue is that I have very high temperatures. Idle temperatures are anywhere between 45-60 celsius and basically whenever I do something on the pc it can spike up all the way to the 70s. When I play games it can even go as high as 85 celsius. I disabled PBO and I set the fan to go to 100% usage once the temperature hits 65 celsius. If there's any setting I'm supposed to turn on/off in the bios that I'm missing or if there's anything else wrong please let me know.

Specs:

• AMD Ryzen 7 3700X with the stock wraith prism cooler
• 16GB DDR4 RAM (slots 2 and 4, 3000 mhz)
• 500GB Kingston m.2 ssd (windows 10 boot drive)
• 480GB Intenso SATA 3 SSD
• 2TB HDD
• Nvidia RTX 2070 by Zotac
• TUF GAMING B550M-PLUS
• 650W Seasonic PSU

hey there. You could try tightening the mounting brackets a bit more to see if the extra pressure helps.

I have found personally that higher performance thermal pastes don't make much of a difference, maybe a few degrees.

I'm currently experimenting with liquid metal on my gpu with some impressive early results but couldn't recommend that yet.

Most people would probably say buy a better cooler and if increasing the mounting pressure doesn't help then I'd probably advise that too.

Max temp 95C

 

Get new cooler or try reseating CPU with better thermal paste.

Alright, but the problem is that my temperatures used to be slightly lower before switching the mobo, what caused them to increase?

Pretty hard to increase mounting pressure on a wraith prism

Are you 100% sure? Couldn't be ambient temps that are slighty hotter? Could be new motherboard applying slighty more voltage. Have you noticed an increase in clock speed. You run with PBO enabled/auto?

I disabled PBO but I'm thinking of turning it back on since I increased the fan speed. I still don't like that the fan has to go to 100% just to maintain an "okay"-ish temperature though.

because when you switched the motherboard you would have had to refit the cpu and the cooler so maybe the mounting pressure isn't exactly the same as before.

Like I said try tightening it a bit and if that doesn't help get a new cooler

Can't expect too much on stock cooler. What paste did you use, when installing on the new mobo?

FYI this is the cooler installation: https://www.amd.com/en/support/kb/faq/cpu-7#faq-Installing-the-CPU-Cooler

Aka only a clamp for pressure.

Could be slightly worse than AMD stock paste:

I really don't want to change the thermal paste, working in this mid tower case is very fiddly and annoying and I don't want to risk breaking anything. Is there anything I could do in the bios to combat this?

You've upgraded to a board with a much larger VRM package. 

The VRMs and Cpu will share some heat through the tracings in the PCB, thus the higher average temps.

Also, some thermal pastes will actually perform better after a nice burn in. 

This burn in period can take a couple of days to a couple of weeks depending on how heavy the usage is.

Your temps are fine otherwise. Nothing to really worry about here. Not much we can do to battle transistor density.

You can try with less vcore. Setting a negative offset for instance. I would also recommend disabling PBO or just setting it to auto if you want to lower vcore.

Looking back I may have also applied a bit too much thermal paste, could that cause an issue aswell? I just wanted to make sure that it's spread evenly across the entire cpu.

Depends on how much. Most of it should just be pressed over the edge of the cpu die. In most cases you get better performance with a little too much, than too little.

Why not just get a new CPU cooler? If you want something cheap you can go for something like a EVO 212: https://pcpartpicker.com/product/HyTPxr/cooler-master-hyper-212-black-edition-420-cfm-cpu-cooler-rr-212s-20pk-r1

I have the 2700x and was forced to get an AIO as the fan supplied with it wasnt upto the task of cooling it hitting 85*c while gaming.

I guess I might in the future, but it for now I think I'll just deal with the slightly louder fan.

Try reseating the cooler with a blob on the cpu. If you can't determine what is the exact center, then apply on cooler if paste is not to viscous.

Alright thanks for your help!

The 3000 series runs hot like that on the stock cooler unless you undervolt. 1.15-1.2v should allow you to get decent clocks (3900mhz+ unless you have a really bad cpu)

You may even run higher clocks under sustained loads like I did before going ham on my undervolt (I had 4.1ghz all core under 1.2v regular program max temp 76ºC. stock operation peaked at 4ghz, throttled me down to 3.7ghz in sustained loads with temps approaching 90ºC.
