Dumb Question about 5600x vs 5800x temps

1 : Anonymous2021/11/29 09:40 ID: r4sawo

Money isn't a problem and i definitely want the 5800x concerning everything else, but my room has poor ventilation and gets warm very easily from my pc.

Will the cpu be a problem in terms of temps compared to the 5600x?

This is in relation to heating up my room.

Just get an 5900x then if money is not an issue. Better temps.

If stock 5800x, 5900x and 5950x put out the same amount of heat since they have the same power limit.

ID: hml4x8o

The 5900x runs cooler than the 5800x because the 5900x has the heat more spread out across the IHS making it easier to cool.

There seems to be a great variety between samples and it is more pronounced with 5800x There are people who run it without problems with simple tower coolers and there are people with hot chips under 360mm aio or custom cooling. But i highly doubt you will face thermal throttling in normal application with 5800x. Especially if you play around with curve optimizer or set all core setting. I have one of those “bad” 5800x samples.

Do you also get high temps if PBO is disabled?

I was thinking that maybe the variety in results comes from each motherboard applying different power limits with PBO.

I am sure it’s cpu sample. I actually had 2 different boards, gigabyte aorus b550 pro - it died on me and i replaced it with Strix-f. CPU behaves in the same manner. I use custom pbo limits of 145/92/115 because i am thermally limited anyway in benchmarks - i cant reach higher than 16200 score in cb23 with custom waterloop, very sad. Higher edc only makes it worse. But the boost in games is pretty solid.

My 5900x (so, not a 5800x) on manual 4.3ghz oc (1.21v) with pbo disabled hits 90c super easily during occur stress test. And this is using a 360mm Arctic aio (seated correctly, triple checked getting same temps every time). I can’t even get it to 4.4 without failing stress tests with errors and/or getting insanely high temps. I guess I was super unlucky with my cpu, but pbo is definitely not the main culprit.

I bought a 5800X and chilled this bad boy with a 420mm all in one. I currently play a lot of Battlefield and a lot of no man sky. Maximum temperature of almost 50 C and that only if I play really long. If temperatures are your problem and money doesn't matter, you can build a custom loop. lol

ID: hmjmoqr

A 420mm AIO for a 5800X seems like tremendous overkill unless you’re planning to slap in a 5950X or the upcoming vcache 16-core for high workloads later.

I have a 5950X that I use in my work from home 3D rendering PC and even a 360mm keeps it well in check.

ID: hmjr2gh

I don't like fan noises, my PC is not audible even under load.

ID: hmkt9is

Cooling is good

ID: hmkkc1t

I used an Arctic 420mm AIO on my 5600x because lower is better, and silent is best lol.

define warm lol, unless the cpu is hitting the 90s you won't be getting issues in terms of performance since this is the CPUs thermal throttling limits

ID: hmijebe

Not really worried about performance, worried about cooking myself

ID: hmiycdr

I think you are confusing heat and temperature.

The 5800X might reach high temperatures, because the heat produced is concentrated on a single chiplet and it's difficult to dissipate that energy, but the amount of heat a 5800X produces in comparison to another processor is not going to contribute significantly to increasing the temperature in any room.

You yourself already add at least 100W per hour from body heat, mid-tier GPUs are around 200W, and smaller electrical heaters start at 1,000 or 1,500W, just to give you some examples.

A 5800X only adds 140W at peak power, so only a 70W difference or so when compared to a CPU like the 5600X.

If you had a 200W CPU paired with a 300W GPU you could start worrying about increasing temps in a poorly ventilated room when at full load for long periods, but a 5800X by itself is not going to be a significant factor.

Your cpu definitely lowers clock speeds before hitting 90c

Also I’m not sure why people think heat doesn’t matter even if it wasn’t throttling. When I turn pbo off using a dh15s it directly impacted my gpu temps

ID: hmk12s5

Also I’m not sure why people think heat doesn’t matter even if it wasn’t throttling.

Because that's how intel does it. ​ IIRC Intel has (stock) 3 states: turbo, normal, and thermal throttling.

Ryzen processors dynamically adjust clockrates based on temp - the same piece of silicon at 80c will be clocked lower than at 50c, and 20c, the term AMD uses for this is 'precision boost' (not PB overdrive, that's different).

If you can handle 150W of heat casually being dumped into your room, sure go for the 5800x. I honestly wouldn't unless you need the extra threads and cores.

ID: hmijhjx

Shouldn't they be similar temps unless I'm rendering something?

ID: hmil2jt

temps≠heat but yes, during normal use, they'll heat your room around the same

you can also reduce ppt in bios to make your 5800x heat your room less than a 5600x while matching it in performance during rendering

7 : Anonymous2021/11/29 11:23 ID: hmiq8oy

I think you will be fine. I was actually surprised with how well the temps are on a 5800x especially when i'm only using a small single tower cooler the ID cooling SE-224-XT but then again it's in a decent case (4000d airflow) and i'm getting 30-40c idle and 55-68c gaming and like 80c under cinebench

8 : Anonymous2021/11/29 16:53 ID: hmjs9dt

Use Curve Optimizer and lower PPT to 120W or less. At most you'll lose 100-200MHz in 100% all core loads. I cool mine with a Wraith Prism, 80W PPT and it doesn't reach 80°C in video rendering while sitting at around 4.2GHz. In gaming it reaches 4.5-4.6GHz and 4.85GHz single core boost.

80°C is equivalent to 176°F, which is 353K.

I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand

Good bot

5600x will definitely run cooler.

What kind of case and cpu cooler are you using

10 : Anonymous2021/11/29 17:46 ID: hmk040v

Doesn’t get as hot as others have claimed for me with a 240 mm AIO. I’ve never seen it hit over 80 while playing Cyberpunk 2077.

Thermal dynamics states no, basically insignificant difference. Ryzen is very efficient, just because the temperature may say something quite high, doesn't actually translate to producing more ambient heat to be dissipated.

Even though my i7 3930k idles at about 27C and spits out 65C maximum load while overclocked, it's peak wattage is in the realms of about 200watts minimum on it alone. Meanwhile a 5600x can hit 95C but it's using basically 1/2 to 1/3rd the power and MOST of that is going into the workload as efficient work rather than straight heat compared to the i7.

If you're gonna use the CPU at 100% constantly. Then yes, it will warm up the room.

What about you install an air extractor on the wall? Your room needs some airflow management, not your PC. 🙂

12th gen uses less power (thus creates less heat) while gaming and gives more performance.

But if your looking at solely what will give you the least amount of heat in your room, regardless of performance, it's the 5600x at stock, though an undervolted or PL2 capped 12600k would give you the best of both worlds, but requires a little tweaking.
