noctua nh-l9x65 se-am4 cooler on a Ryzen 5 5600X?

[Tomgang]

Just a simple question to ask.

Does any one use a noctua nh-l9x65 se-am4 cooler on a Ryzen 5 5600X or similar cpu and can tell me about temperature or if it is even a feasible achievement?

It's because I will put it in a asus b550 strix mini-itx baord with a limited space between cooler and a vertical mounted gpu. Hence I am cooler size limited. But it also seems despite 5600X is a 65 watt tdp cpu, it can run quite hot.

It looks like the entire 5xxx family runs dummy hot to begin with. You should be fine.

I hope so, cause I know there are aio options. But aio tube length is a problem as well. So the easiest solution is a small air cooler.

 

[Mussels]

the chip will run upto 90C because yay zen 3, it'll just performance throttle to some extent.

I highly recommend running Eco mode or tweaking your PPT settings to keep multi threaded power down, and then you should be perfectly fine with a weaker heatsink.

Yeah that is an option, but an option that will reduce performance. But I guess it better than the cpu runs melting point the entire time.

Hmm maybe by tweaking voltage and use the new curve feature. That might give me som lower temperature with out sacrifice to much performance.

I guess I really don't have an option than reducing power consumption. Causes as all ready told. Bigger air cooler is not an option and aio is not either because of to short tubes.

ID Cooling AIO's seem to have longer hoses, some sites list the length which makes selection easier.

Ah i will take a look at it then. Thanks for the information.

absolutely not.. only the 5800x because it has the same powerlimits as a 5950X and consumes under stress almost 20W per core.

for comparison.
my 5800X under Water runs at 80°C in Cinebench.
my 5900X on a NH U12S tiny 120mm cooler runs at 58-60°C in Cinebench.
with my AIO i barely see more than 50°C.

tell me about temperature

Don't forget, ambient (your room) temperatures play a big factor in cooling. Also remember it is the case's responsibility to provide a sufficient supply of cool air flowing through the case. The CPU cooler needs to toss the CPU's heat into that air flow. If you don't have enough cool air flowing through the case, it does not matter how efficient the CPU cooler is. I would rather have excellent case cooling and a weak CPU cooler, than poor case cooling and a strong CPU cooler.

If you are stuck in a traffic jam, it does not matter that you have 650 horses under the hood.

If this mini-ITX board is mounted in a tiny case, you may not have enough cool air flowing through the case. If you cannot add another case fan, your only option may be to live with higher temps and the consequences they may bring.

I am well aware about ambient temp. Case airflow is as good as it gets. It´s for a dual system in one case and the case is phanteks enthoo 719. So airflow is plenty.

howd you get your 5800x that cold? mines... toasty.

I probs need better than kryonaut paste

You'll be fine. The fact that the 5600X ships with a Wraith Stealth, a far shittier cooler than the L9x65, should tell you everything you need to know.

With strong airflow, my L9x65 could just about tame my 4790K at 4GHz all-core with very high default Vcore in P95 Small AVX. To this day, no chip I've owned has even come close to measuing up to the thermal challenge that is a non-delidded 4790K. If you want lower temps you can always mess with the curve optimizer/undervolt in any AGESA 1180 or later BIOS.

Though I will say, the L9x65 really isn't a performance cooler, even if it's miles better than the L9a. If you're not actually limited by case clearance, there are better SFF options for your money out there. Even just amongst Noctua.

L9i/a ~ Wraith Stealth <<< L9x65 < D9L ~ L12S < U9B SE2 ~ U9S < C14S.

I have all those coolers except the L12S and would probably just tell you to get a U9S if you want easy to install, decent performance in a small size and just let it do its job. The difference between the U9S and L9x65 is like $10 where I live.

I am cooling limited be cooler size. The cooler will be behind a vertical mounted gpu and U9S is simply to big. L9x65 or an aio is only durable solution I have.

How much clearance from the top of the A9x14 fan on the L9x65 to the backplate of the GPU?

While it won't necessarily be a *problem* for the CPU, temps may end up higher than you'd personally like.

Top-down coolers have potential but they suffer tremendously if they aren't provided good direct, top-down airflow. The L9a/L9x65/L12/L12S/C14S all work this way. If you want to compensate for that solely using case airflow from the front of the case, that airflow needs to be really, really abundant.

This is from another Phanteks enthoo 719 build. Look at the system in the buttom of the case. This is cooled by an aio. But as you can see there are really not much clearance between gpu and aio pump head. The same will be the problem for an air cooler for my system.

There's very little clearance there. I thought you said you'd have great case airflow? I'm not seeing any fans whatsoever blowing towards the ITX board in this case...

How much the GPU affects the L9x65 depends on the GPU you use, but you're probably better served with a 120mm AIO. Like I said, the L9x65 is a decent low profile cooler......if you have excellent airflow to sustain it.

Unless there's another position for a 120mm fan in the empty space below the 360mm rad in the front in that picture. But even then, the fan is so far away that unless it's a 3000rpm NF-F12 iPPC at 50% or higher RPM, no actual airflow is going to reach the ITX board.

Or if there's another spot for a 120mm fan directly below the board on the bottom of the case, that could work. But I imagine you'll probably be using a GPU riser, so the ribbon cable would be blocking all the airflow from that fan even if you could fit it.

I'm at around 75°C in multi-core and 82°C in single-core workloads with a 5600X on a Noctua U9S. Idle is in the high-50's. It's currently summer here in the southern hemisphere and I don't use the best-performing thermal paste, although regardless I'd be hesitant to go with an even smaller cooler.

I am aware that I might have to mount a fan closer to the gpu/cpu cooler.

The problem with an aio, is that most have to short tubes to front mount it and mount it in buttom of the case means pump is the highest level and that means air bobbles in the aio can go to the pump directly and shorten the life span of the pump and lower it's efficiency as well. So air cooling seems most sensible for reliability and cooler life span.

 

[tabascosauz]

Yeah, the AIO thing definitely isn't ideal, but neither is choking a monolithic top-down cooler by having it breathe from the back of the GPU.

Where would you mount a fan? That airflow needs to be direct, so if you put a 120mm where the bottom rad is in that picture, it'll do precisely nothing for the CPU. The only suitable place for a fan I can think of is directly underneath the board in the bottom of the case, but clearance might be a problem and the riser cable could block pretty much 100% of the air coming from that fan.

Again, what GPU are you going to use for the ITX system? That'll play a big part in determining whether a L9x65 will be enough.

 

[Tomgang]

I'm planning to mount a fan by the end of the gpu cooler to blow away hot air. So both gpu and cpu cooler is not choked by hot air circulating around that area.

Something like this, but hopefully pretier solution in my case. Are looking in to it. But a fan just behind the gpu. I'm planning on using a Asus rtx 3060 TI tuf gpu.
