Really quick temp jump on aio

[svenlaene]

Hi. I recently build my pc with a 5900x and a artic liquid cooler 280. Rev4.0 mounted normally not the Ryzen specific mount. And I noticed that even when doing quick high power jumps my pc would jump up in temp really quick . I have my cpu cooler set to 70% min and the 85% at 60c and 100% at 80c.

 

I assume that this is not supposed to happen that quick. So I tried repasting the CPU. I am using kryonaut thermal paste. But that didn't help at all.

 

If anyone has a idea why it might do that please let me know. I included a video of what happens. Gpu is normal just wanted to stress both. If I don't stress the GPU the same happens.

 

If I keep the CPU loaded the temp doesn't really rise any higher. After about 83c. The pic is how it's mounted inside a meshify 2 without the top filter.

@svenlaeneSounds like there's an air pocket in the water block on the cpu,

@svenlaene that's just a guess but if the water is cool that does seem like it's getting hot fast, are you overclocking?

Might try to flip the system to get any possible air out Tomorrow. Nope no overclocking just the boost thing. Can't remember what it's called

Its the CPU temp not the actual AIO fluid temp?, with the 5800x it does something similar with it just jumps in temps when under load and stays there, even with custom loops.

Yeah it's the CPU temp. That's weird I thought water coolers where meant to absorb shorter burst of power. Because the water needs to heat up.

Yeah but it takes time it's not an instant thing. So if the temp spikes it's gonna take a few seconds to cool it down.

 

Looking it up AMD says it should hit a max of 86'c with a 360mm AIO. So If it's like the 5800x it's probably designed that way. The temps on the higher end 5000 series are weird.

It does seem high if you're not overclocking. Yea I would make sure there isn't air in the top half of the water block. If there is that could be the problem, you want water contacting the entire block.

I would imagine that's under sustained load and after the water warms up, he's getting to 80 in like 1 second.

Another thing you could do is watch a video of someone benchmarking that CPU and compare the temperatures, it's possible that's normal but it does seem a bit off to me.

 the 5800x does this (that's how it's designed according to AMD) and looking around online (quickly) everyone is reporting the same thing with the 5900x. The 5000 series runs hot and completely different to the previous gens of Ryzen.

Kinda makes sense. More cores and power limit then previous gens I guess?
