Ryzen 5900x going 50-70C on the desktop?

[x Princess Leliana x]

That cant be right. Mustve buggered up thermal paste application or something, mostly just want someone to confirm that before I go taking it apart again.

 

My fan curve is set to 40% until 55 degrees, then ramps to 100 by 70 from there, so it shouldnt be the curve thats doing it. 

 
Idling on the desktop now, with nothing open but google, it goes from around 45 degrees, where the fans go to 40%, nice and quiet, this is what I want, then out of nowhere it goes up to 70 degrees, fans spin all to hell, and it awful. Then after the fans spin itll go down to say, 50. Rinse repeat.

 

I have a triple rad AIO, cant remember the model, so I should have adequate cooling. Only thing I can think it could be is bad thermal paste or maybe not enough mounting pressure (screwed it down till I met with resistance, then left it, think thats the "finger tight" im told its meant to be) , not sure what other issues there could be, my gpu stays in the 30-40 range without the fans ramping up ever at all. Not sure what to do.

Screw everything down with a screwdriver, nothing is supposed to be finger tight. If you have RGB software, could be that too.

Not doubting you, just want you to confirm that, Im worried ill screw it too tight and break the cpu, literally everything Ive read online, even in this forum, is "as tight as you can do it with your fingers"

try cinebbench r23, and if the temps are below 85-90c id say its fine

HW monitor is giving me 73 degrees full tilt in cinnebench.

 

But that must mean something is wrong, why is it getting the same temp on desktop compared to running a heavy duty benchmark?

Ok.. But its pretty hard to have the correct mounting pressure if things are done just finger tight.. FWIW I am idling 15c cooler than you, and only see 70 in a game. And I am using PBO and boosting to 5150 with a heatsink..

 

But read your manual and install like they say to.

Yeah ive done that, i just dont know what to do to fix it haha. Like I open google and it spikes up to 70, then back down to 50. It stays at 50 ish if i do literally nothing, which is okay, but anything minor spikes it.

That is AIO life on a 12 core I reckon, I see no such spikes.. 

 

But everyone here with a big  AMD CPU and AIO say they see the same behavior, and they show the same relative temps. At least that is what I have seen so far.

I still wanna get it down, im going from 60-75 in a game im playing, would rather keep that to 60, any other tips to combat it?

You could try to repaste the CPU.. but before you go through any of that trouble.. what is your ambient temp like? So for me right now its 20.5c in my space, I have the windows open. How is your rad setup, is it intake or exhaust? It should be intake so you always have fresh air through it.

Idle on desktop is 50c ish with spikes. Idle in this game is 60-75.  I have a triple rad AIO, ambient temperature is around 26-30, im in a hot room during summer, and hoenstly I do not know if its intake or exhaust, its on the top of my pc, with the fans on the inside of the pc, the fans have the "Open" section (without the cross bracing behind" facing the computer.

It is probably the hot room.

My 5900x has low temps in benches and idle with a EK 360mm AIO but it is in a room that is at a constant 21c all year round.

If I put it in a bedroom under a desk it will run a lot hotter. 

 

Also some cores run hotter than others.

This is my 5900x after a R20 run. As you can see the cores 09 and 10 are hot but the rest are not. Under load they are about the same.

These hot cores bring up the average temperature.

Even under load yours is still 10c cooler than mine, I wanna achieve that haha. Whats your fan curve like?

26-30c,

That's 78 to 86f Room temp.... ouchy.

 

Put a window unit in your room window..... Yeah.... And that should get you the lower temps.

 

So essentially, your PC is a room heater. Now you need a waterblock and radiator for your room. Or a nice little phase change unit should do the trick!

It is set up to be quiet. With this the fans don't ramp up when it boosts.

Thank you ^^ Maybe I will re-apply thermal paste, since idk what else it could be that mine runs double digits hotter than all of yours

If you are going to repaste, might as well make it so the fans are pushing in cool fresh air through the rad.

A repaste won't repair the issue.

 

The original poster is dumping additional heat in the room that's already hot.

 

End cooling solution to all ambient cooling types is the ambient air temp.

 

That's why OC picks up in the winter. People can really show off!!

Rooms only 26, cant be contributing that badly to it? Half tempted to return it and put my 3600 back in, didnt have these kinda issues with that hahah

My garage, with a simple window unit is 77f and 35% humidity. I don't have temp issues though, because I'm running a much smaller processor. 

In the winter with the heat on, 65f. The difference is quite large. 

So you and I are running a higher temp gradient. High idle temps is kinda normal.

That and taking into account the transistor density as well. THe spikes for AMD chips is pretty normal.

Inside my house, nice and cool 72f. The 2700X runs about as cool as the 12400F out in the garage. 

Imagine that, it's only a 5F difference, but thermally the 2700X easily hits 140w (it's at stock)

 

Before I repaired the house AC (needed a charge 410A) the 2700X was doing the exact same thing as yours is. Now I leave the fan curve in silent mode and it's just fine. But that's just to example only a few c or 5f difference in temps. sometimes it makes the biggest difference. Especially if you can lower the humidity, that helps also. Dense air isn't as efficient at moving thermals as dry air. Though this could be argued that it does help make things feel hotter lol.

I just dont think its gonna be healthy for this thing to be running at 50-70 for 12 hours a day.

The cpu has a MTBF or 100,000 hours at load, all cores 90c or less.

 

However, according to the white sheets, the high temp alert is activated at 70c, the point a default system will command 100% cpu fan duty cycle. Your bios is generous enough to extend this to 75c in the fan profile.

 

But so far, you haven't listed any unsafe temperatures. So there's little worries.

 

Maybe turn the pump up to high speed?

"finger tight"

First thing I'd try is increasing the mounting pressure.

Finger tight is not enough.

Do you know where thatd be in the bios?  

 

Still, no one else is reporting it just going to 75 when idle. Like I have been cooking, pc doing nothing, and it just goes up to 75 sometimes for no reason. That really worries me.

Sure it is.

 

@Somerandomtechyboijust sets his cooler on there.

 

You'd be surprised the amount of clamping force a few inch pounds per screw can create.

 

In a serious note, with a firm grip (like dads old mechanic grip) it sometimes is too much.

 

If the cooler feels tight, like it doesn't slide around easily, the cooler is tight enough.

 

In my humble opinions of course.
