Should my Ryzen 7 7700 be this warm?

[Elthrael]

Two things first off: I know AM5 chips are designed to run hot without problems, up to 95°C, I know how the boosting behaviour works etc.. I've also read a few random reddit posts that say this is normal, but to me, it still seems a bit much.

I recently bought a Ryzen 7 7700 (non-X), and put it in my old case with my old cooler. Idle, it sits around 45°C, sometimes when I'm doing some light browsing it goes up to 50-55°C when watching a 1440p video on YouTube. Curiously, under gaming load, it's around 70-75°C, and even after about an hour of Cinebench 2024 loops, HWinfo64 reported it never went over 82°C, and the average per-core was comfortably under 80°C.

The motherboard is an ASRock B650M-HDV/M.2. The cooler is an Alphacool Eisbaer Aurora 280 AIO which handled my 24/7 fixed OC 8700K for years just fine and that chip sucked down 120W easily. The case is a Fractal Design Define R6, not the best airflow case but it works well with AIOs. I used quality thermal paste (Thermal Grizzly, I think it was Hydronaut), I made sure the cooler is seated properly, I made sure the BIOS has proper information to change the temps accordingly. My case fans are at 100% all the time (no reason not to since they make literally NO sound) and my AIO's fans are tied directly to the CPU temps. My ambient temp is around 22-24°C and it's pretty stable, thick walls and all that.

Do these seem normal for Ryzen 7000 or should I be worried?

temps could be better.....but are not a problem at this point....

things i would do.....make sure the pump on the AIO is at a 100% constant.....play with fan curves to speed fans up at lower temps then current settings....under volt the CPU in bios settings so there is a voltage curve going in to boost clocks, a minus 0.02 voltage offset at full boost can drop temps by 15C in some cases.....

to be blunt IF your coming up on the 5 year mark for that AIO i would watch it like a hawk as its coming to end of life cycle.....

if your in the US for 55 bucks you can get a really good 360mm AIO new.....

C'è la startap di una tec tutta Italiana che potrebbe risolvere il problema.

An Italian technology startup could solve the problems.

Unusually high temp for this specific CPU with an AIO. It shouldn’t go much over 70C under load on a decent air cooler.

[Elthrael]

Honestly, it's not the under load temps that worry me, it's the high idle temperature. Just south of 50°C when just sitting idle at desktop with NO active foreground tasks feels really, really bad.

Yep, I did that first thing, I connected the pump to the CHA3/WP3 header and made sure that header is set to "WP mode" in BIOS, and the only setting possible for that mode is "Full Speed", no other options.

The way fan curves work in this particular board's BIOS is extremely clunky, you basicallly type in values into a menu without getting the actual visual representation of the curve. I've tried using the "silent" and "high performance" settings and it didn't seem to make much of a difference, idle or under load.

It does actually work too, the fans audibly spin up when it's under load.

EDIT: I'm a dummy, found the curve editor, will mess around with it.

I have no experience with this, but I'll give it a try. I researched overclocking (but not undervolting) before buying into AM5 and I came to the conclusion that OC is not worth it (usually actually leads to performance regression or same performance with worse temps), but not undervolting. Right now I have EXPO loaded and everything set to auto, maybe the board's default boosting behaviour is a tad aggressive.

I was actually considering canning it and going for a nice air cooler like the Scythe FUMA or Thermalright Peerless Assassin, but I thought why not use it since it still works.

What would be some signs (apart from iffy thermals) that it's on its way out? It has a refillable pump with a window, and to be honest, I think? remember there being more liquid in that pump when I bought it... In the manual, it says " If the pump is running unusually loud, liquid should be topped up urgently." Pump is dead silent. Should I just refill it to be on the safe side? Or will that not do anything or even cause problems?

That's what I was expecting, tbh. The 8700K I mentioned I had, even though it was constantly on 1.35V and 5.0GHz all core, usually hovered around 65-70°C in gaming and it sucked down a good 30W more. It did, however, easily reach close to 90°C after even short, sustained loads like video rendering or Cinebench testing.

[Elthrael]

I checked out Hardware Unboxed's original review of the 7600, 7700 and 7900 and when he used the 7700, it had better temps without PBO than mine, but around the same temps as mine when using PBO (his hit 85°C on a 360mm AIO). I did notice that the voltages on PBO were pretty darn high, approaching 1.38V. His "normall" results had the voltage lower, around 1.15V.

OK so this is weird. I went into BIOS and there's a setting called "Performance boost" which has three options, "Auto, cinebench_test1, cinebench_test2". So I left that on "Auto". There's another setting called "Performance (something else)" which has Auto and then twelve descending options, three of which are "PBO, TjMax = 85/75/65°C" and then each of those also has a "curve offset -20/30/40mV" variant, so I chose the "lowest" one, which was

PBO, TjMax = 65°C, curve offset -40mV.

I then ran a single pass of Cinebench 2024 just to see what's going on and the darn thing hit the same clocks as before on "Auto", but at 66°C and the voltages dropped from 1.35-ish to 1.15, just like in Steve's review.

Thing is, it still idles at 45-50°C, but the voltage hovers around 1V anyway, so even when it's under load, the voltage barely increases.

Is there some kind of "off/boring/no boost/Intel Power Saving" setting that I'm not seeing and that's why the idle temps are a bit higher?

[Heretic]

High idle temps probably means a poor cold plate and/or paste, but even 45c idle isn't terrible if you're going for near silent running. I assume you're on a balanced power plan and your case and case fans are decent enough.

When I moved to Ryzen from Intel I learned to run them warm, because of the way their CPUs boost (more rapid than what I was used to), so idling at 40-45c wasn't a problem for me since I didn't want to hear the boost when I was just opening a web browser. I did this intentionally though the fan curves on mobo.

[Rumpelcrutchskin]

Those temps are bit on high side but they are not too hot or critical for AM5.

[smokerob79]

most motherboards give a little more juice then needed to pump their numbers up on bench marks....so many motherboard makers have been slapped with issues over "overvolting" CPU's its caused intel to fall off a cliff......

[AmaiAmai]

There are so many variations with boards, it is best you ask your board's manufacturer whether or not their auto-OC implementations override your user set ones.

Considering your temp rises so much when just browsing, almost certain you left those on.

I think I did a good job with the pump+coldplate mounting, I did it out of case to make sure it has even vertical pressure when I tighten it down, it's snug and the thermal paste used was Thermal Grizzly's... Hydronaut, I think? Case is Fractal Define R6 and it has two front intake fans (140mm) and one exhaust (140mm), they're all on 100% (they don't have PWM).

Funny enough, the fan speed of the AIO fans doesn't seem to make much of a difference to the idle temps and temps when doing everyday stuff (i. e. not gaming, benching, rendering). 30%, 50%, 100%, the CPU just hovers around 45-50 degrees.

Yeah the 60°C when watching YouTube definitely stopped since I applied the "PBO, TjMax = 65°C, curve offset -40mV" preset instead of the "Auto" one.

One more thing... the actual individual core temps are pretty low when idle, low 30s. I guess that means I'm good?

what aio cooler are you using?
if its a 120mm rad, then its too small even a 120mm tower cooler will be better than that

make sure the pump is at 100% all of the time, and its fans are using the cpu header
then it will always have cooling flowing, and cool the liquid as needed

I'm using an Alphacool Eisbaer Aurora RGB 280mm AIO, it should be more than enough.

I have the pump connected to CHA_FAN3/WP and I have that header set to "WP" mode and "Full Speed" in BIOS. I also logged a 30min Cinebench run and checked that the speed actually stays at 100% (the RPM didn't change the entire time).

is ti throttling?

how is the cooler mounted?

[Elthrael]

No, it's nowhere near throttling, it wasn't near throttling even at stock settings. Now that I've set the Performance Preset to the lower TJmax and -40mV offset, it stays around 75°C under full load, I just did a 60 minute Cinebench loop to verify.

I was just a bit concerned to see idle temps near 50 with the stock settings.

If you mean the AIO, it's top mounted with fans set to exhaust.

[Elthrael]

After some more testing, I think I'm ready to call it case closed, it just runs that way.

I ran three 1 hour Cinebench tests, one for each "Performance preset" setting:

Auto: runs the worst. power draw 95W, boost clocks never go above 5.2GHz, effective clocks barely go over 4.9GHz, avg voltage is a whopping 1.2V with spikes to almost 1.4V. Worst Cinebench score, around 950-970, occasional 980 score (12 passes in 1 hour).

PBO, TjMax = 75°C, curve offset -40mV: power draw is reduced to 85W, boost clocks reach 5340MHz no problem, effective clocks around 5050MHz, avg voltage is 1.08V with occasional spikes to 1.18V. Cinebench score slightly better than Auto, first time I broke 1000 pts multiple times (at least 5 times in 12 passes)

PBO, TjMax = 65°C, curve offset -40mV.: power draw further reduced to 80W, boost clocks still reach 5340MHz albeit a bit less frequently, effective clocks reduced to 4960MHz, avg voltage is now 1.04V with the same 1.18V spikes. Cinebench score more or less the same as the previous setting, higher than Auto, and it broke 1000 pts maybe 2-3 times in 12 passes.

Idle temps? The same across all three settings. 45-50°, although with Auto settings it keeps spiking up to 60° during normal stuff like opening low-cost apps (Word, Edge, Explorer), with either the 75°C or 65°C and -40mV offset it stays at 50 or under.

I'm glad y'all encouraged me to fiddle with the OC settings because I never would've even considered it since I had no intention of fiddling with the chip at all. Now I have a system that's basically silent and cool under full load while running at 97% of its full performance potential.

Thanks to everyone for helping me optimize the hell out of this setup!
