Ryzen 7000 Runs HOT but Does it even Matter?

Some people say the 7950X, 7900X, 7700X and 7600X run "hot". But does it even matter when you compare CPU performance and clock speeds? That's what we wanted to find out with different AIOs and air coolers. And the results are pretty shocking.

This testing was extremely well done and well explained - great work! This makes me feel way more comfortable choosing a cooler that’ll be best for my build

[mrpekko]

Finally, someone trustful who actually tested gaming scenarios temps. Everyone is just rushing towards synthetic benchmark to hit the headroom of the CPU for their audience, but little did they know, most of their audience are gamers and are looking into gaming performance benchmark. Glad we got people at Hardware Canucks, who think outside the box. Who knew the 7000 series were running below 70c for gaming? Not me, well until now.

[johnvandeven]

This review I found much more informative and realistic than artificial stress testing. Cheers.

[Tesla]

This video helped clarify alot, thanks! I was worried that my high temps (48-68c idle and 70-80c at load) were related to that whole exploding chip fiasco.

[corentinrobin]

Mike's cooler videos are imo the absolute best content Hardware Canucks makes. It really revitalised the channel.

[KleoYan]

Hi, thank you for the full explanation and greatly appreciated it. I tested the 7950x, yes it does stays 95 degrees but and clock frequency does depend on the cooler’s capabilities. But if you tweak in PBO2 by lowering the PPT by 1/2 which is 115w instead of 230w you can still hit the 5ghz mark with boost but with a lower temperature. I do agree with you if allow to, best is by getting the best cooler pc builders can get. Am running off a 420 aio which benefits the clock frequency and boost.

[StaySicEver]

What I'm waiting is to see the X3D version eventually, how the heat and clocks will be managed this time around. Should be interesting especially since they plan to release more models.

So Ryzen 7000 has made liquid cooling redundant, that is ironically cool.

[TheDaNuker]

Excellent charts, been looking at these for really heavy workloads so these kind of performance-loss to temperature charts really helps as a rough gauge. Thanks for doing this testing.

[nwheatcraft]

Thank you for going into the gaming bit. So many people think that when their cpu says 100 in game on an osd that it means the cpu is maxed out in every way. They also associate 100 usage to highest temp. This will go a long way to correct this issue with some.

[RafitoOoO]

AMD handled really poorly their explanation about how their chips run. Intel chips have been running at 100°C if unchecked for years and no one bats an eye, AMD could've explained it a lot more better, also undervolting it with PBO2 makes it run way less hot without losing any performance. In my eyes this is a masterclass about how to fail at communicating with your consumer base.

[Meatpipeify]

This was very interesting. I recently bought a 7700X and the Wraith Prism fan ramping up and down due to temp spiking was driving me nuts. I had an old Deeopcool Gammax 400 that I put a Noctua fan on as a temporary solution...temps and frequencies are about the same as as the Prism but much quieter. During typical gaming sessions the 7700X hovers around ~70C with the Gammax 400.

Very informative video, where many/most scenarios are covered and explained. But after reading comments, there's still a lot confusion about HEAT. I've watched many Ryzen 7000 video "studies" talking about 95°C, where people keep asking about heat, but the only answer we get is "no worry, 95C is now 65C" -which (to me) sound like avoiding to answer & explain actual question. Saying (here in comments) "Just because something runs hot, doesn't mean it outputs more heat" isn't really helpful (even it's true!) -it needs an explanation. Not to mention stupid comments like "Gamers have proven with this launch that they REALLY don't get physics." What many wish, is the clear answer to the question: will now more heat come out of PC? And if yes, by how much?

Measuring unit for amount of heat is Joule and measuring unit for power is Watt. How these two relate? The answer is: 1W=1J/second. We can see, that amount of heat only depends on power (equation doesn't contain temperature). That is, temperature has nothing to do with amount of heat. First thing that comes to mind is "wait... but 95°C is hotter than 65°C.. and so it must create more heat.". No, it doesn't! Here's an example which hopefully explain this:
Let's assume we have a CPU (with some "normal" cooler), which has temperature of 95°C when powered by 100W. Now we only change the cooler with a better one and CPU temperature drops to 80°C. Does that mean, we generate less heat now? Of course not. Amount of heat can't just vanish by changing the cooler. By changing the cooler we only reduced CPU temperature -because better cooler dissipates (the same amount of heat) more efficient. Again, amount of heat only depends on input power. And this also explains the following claim: at given power, the amount of heat dissipated out of PC case remains the same, regardless of CPU temperature and what cooler is being used.
In short: if one CPU has 95°C and another has 80°C, and both consume 100W, then both PC's will increase the room temperature by exactly the same amount (because both dissipate the same amount of heat). The only way to reduce (or increase) amount of heat, is by changing power.

Thank you for reading

[andrebrait]

I wish you had tested it with the power limitat set tl 105W or 65W. I've seen reviews saying there wasn't that big of a performance impact and thermals were a LOT tamer.

[sauhamm]

as a gamer i run a 7600x and the ak620… 4k and 120fps and i’ve never tripped north of 60c or so. my cpu fans stay nice and quiet. all core work yes, the am5 chips are fuente. but for every day computing or gaming, you’ll be fine. great video, it helped me make my purchase.

[ItsDisliked]

So basically I've been worrying about my 7700X hitting 95 degree with an 240mm AIO for nothing, thanks for the video! Makes me feel less stressed when I see the temps, haha!

[almostinfamous]

These illustrations are top notch and make the issue very clear, great video thank you guys for the hard work

[alderwolf]

I have a noctua air cooler with three 140mm fans mounted in the top of my case blowing down on it and while I see temp spikes to 95C under heavy load, it immediately cools to under 50C the moment load is removed. Throttling until you hit your thermal cap is AMD's way of squeezing as much performance out of these things as possible.

[Atlanticmantic]

the great things about these CPU's is that you can under volt them lower the over all temps and get BETTER performance.

[Deathscythe]

a lot of people dont understand there is a difference in heat output from a cpu
between 95c 50watts and 95c at 100 watts
