Question I'm seeking advice on PC heat management during summer ?

[NotUrLabRat]

Hey Tom's Hardware community,

I recently assembled a PC that is experiencing heat management concerns, particularly due to rising ambient temperatures during the summer season. I am reaching out to seek your expert advice and recommendations on addressing this issue effectively.

Below are the specifications of my system:

- CPU: AMD Ryzen 9 5900X with PBO2 enabled
- CPU Cooler: Deepcool Gammax L360 A-RGB liquid cooling system
- GPU: Zotac 3070ti Trinity
- RAM: G.Skill Ripjaws F4-3600C19-16GVK (2x16GB)
- PSU: EVGA 750W 80+ Gold
- Motherboard: Gigabyte X570S UD rev 1.0 (BIOS version: F5, built in December 2022)
- Storage: P2 500GB SSD and 1TB Seagate Barracuda HDD

During heavy loads, my Ryzen 9 5900X reaches temperatures ranging from 77 to 82 degrees Celsius, with occasional spikes up to 85-87 degrees Celsius. It is important to note that these temperatures fall within the acceptable range, but I am seeking guidance to optimize heat management for long-term stability and performance.

The Deepcool Gammax L360 A-RGB liquid cooler is installed, featuring three A-RGB fans on the radiator. I have verified that the cooler is functioning correctly and that the thermal paste (Kryonaut) is correctly applied.

Furthermore, I have a well-ventilated case, the ANTEC eSports 690 Air, equipped with three 120mm PWM intake fans at the front, two fixed RPM intake fans near the motherboard, and one fixed RPM exhaust fan. The Zotac 3070ti Trinity GPU incorporates its own cooling system with three fans.

Considering these details, I would greatly appreciate your insights on the following:

1. Given my hardware configuration, are the current temperatures within an acceptable range, considering the rising ambient temperatures during the summer season? If not, what steps can I take to further optimize cooling?

2. Are there any potential improvements I can make to the fan configuration or overall airflow management within the ANTEC eSports 690 Air case?

3. Considering the Gigabyte X570S UD rev 1.0 motherboard with BIOS version F5 (built in December 2022), are there any recommended BIOS settings or adjustments I should consider to enhance heat dissipation or CPU performance while maintaining stability?

Please take into account that the ambient room temperature reaches approximately 35 degrees Celsius during the day and cools down to around 30-31 degrees Celsius at night. Additionally, this is the first time this PC is facing the heat of summer.

Your valuable insights, suggestions, and best practices related to optimizing heat management for the AMD Ryzen 9 5900X, Deepcool Gammax L360 A-RGB, and the overall system would be highly appreciated.

Also, I am sharing my PBO2 details,
CO1: -4, CO2: -16, CO3: 10, CO4: -18, CO5: -12, CO6: 6, CO7: -18, CO8: -20, CO9: -26, CO10: -30, CO11: -12, CO12: -22 [No crashes till now] for All core -20 beyond this it crashes

Thank you for your time and assistance in advance.

How hot do you expect the room to get?

As I understand your post, you have a very good understanding of the system and the environment.

And it is good to be proactive.

However, doing something now could be counter-productive in the longer term.

My recommendation is to "wait" until summer and just monitor the temperatures each day as summer arrives.

Keep a daily log: times, temperatures, system use, etc.. Whatever you deem appropriate....

Graph system temperatures versus room and outdoor temperatures. Look for trends and correlations that the summer temperatures will, indeed, cause problems.

If there is a problem then you will have more information regarding the specifics.

Could be that the temperature variations do not change all that much.

May be just a small room fan would make a difference with no need to tinker with the system itself.

Just my thoughts on the matter.

All cooling starts with the ambient temperature.
Best would be to get a room air conditioner that exhausts air to the outside.
Failing that, open a window and use a house fan to get some better room ventilation.

Left by itself in a closed room, the pc will raise the ambient temperatures.

I just wanted to mention that I recently searched for better all-in-one (AIO) coolers for my satisfaction. However, I found that most YouTube videos showing benchmarks or gameplay with the AMD Ryzen 9 5900X and various graphics cards were reporting temperatures ranging from 77 to 85 degrees Celsius. This seemed abnormal to me because the thermal limit for the CPU is typically 90 degrees Celsius.

In addition, I reached out to Deepcool because some people I know had issues with their AIO coolers. They mentioned that the liquid in the radiator had worn out or had disappeared entirely, requiring them to get it fixed. Deepcool responded by saying that their AIO cooler is not capable of effectively cooling the Ryzen 9 5900X under full load, and suggested that I consider using a different cooler instead.

I'm curious to hear your thoughts on this matter.

These CPUs run hot. While you're not able to control your environment in a home that you don't own as much as in one you do, the ownership status doesn't affect the laws of thermodynamics. I don't necessarily think your AIO is underperforming. If you're that worried about pushing heat the best option may simply be not using PBO.

These CPUs run hot and near thermal limits because they're *designed* to do so. Overclocking is basically using the difference between a CPU's temperature and safe limits as a resource, and if a CPU is running at fairly low temperatures, that means there's performance left on the table, which things like PBO are meant to reclaim, at the cost of more heat.

If your environment is that hot, you may simply not have the option to get everything you want. You'll know better when you're in those hottest months if you can't have all three of hot room, aggressive CPU performance, and good CPU temperature and may have to pick two.

I'm a little unclear as to what you mean by fans "near" your motherboard. Do you mean a side or top intake? If you mean side, that's a decent intake (and you ought to have a couple exhausts on top then too), but if you mean on top, that's a really awkward place to have intakes.

Then you're left with cutting back on power used by the PC. The more power it is using = more heat dumped into the room.
Bigger coolers and airflow friendly cases actually serve to pump that heat out a little faster. Thus, PCs are essentially space heaters.

-Turn off PBO as mentioned by DSzymborski.
-Cap fps.
-Lower the gpu's power limit. You can even bump up the core clock to offset the lower average core clock.

Thank you for your time and assistance in advance.

Open your case wide and put a large fan blowing into it, that's about all you can do without buying a refrigerated air unit for the room it's located in. Some people buy a small AC and duct the cold air into their PC or across AIO radiators which would cool it pretty well. If you do be aware it can create condensation on the PC parts so turn the AC off first and allow the internal parts to warm up before shutting down the PC to prevent that.

AMD has told us that operating at temperatures up to about 90C, or it's Tjmax, is not unexpected and it's designed for it so it is safe. But performance will decline the higher above mid 70's it's running since that is the way the boost algorithm works.

Curve Optimizer is a great way to help it perform better at any given temperature but it probably won't lower the operating temperature in a given workload. I'd test for stability with a utility called Core Cycler, though, to know it's stable. It generates light, bursty workloads on single threads that best show up stability issues from shifting the V/f performance curve.

There's nothing you can do in BIOS to enhance heat dissipation since that depends entirely on the physics of moving heat from CPU components to surrounding air mass, a process compromised by high ambient temperatures. Suggestions you've gotten will probably help lower temperature but at the cost of compute performance. One thing to consider is the boost algorithm is already doing much of that for you as it is temperature sensitive: as temperature rises it lowers CPU performance to keep it from rising too far.

There are lots of knobs and switches that will help keep temperature lower in AM4 BIOS's by killing performance. The easiest IMO is the most direct: simply set a platform thermal limit at the maximum temperature you want it to operate. You have to enable PBO to expose it but don't fiddle with any of the settings (other that platform thermal limit) and it's not doing anything. It will keep the CPU temp at or around where you set it during heavy workloads. Performance is lower but it's not abrupt so there is no sudden throttling where clocks drop extremely low. If you don't move it lower the platform limit is normally 90-95C, depending on specific CPU.

Modern processors and motherboards are designed to ramp up and perform the the best, given the workload and cooling situation.
High temperatures are normal with occasional backing off. 85-90c. for ryzen. 100c. for intel.

Air coolers and aio coolers are both essentially air coolers where the cpu heat is exchanged via a radiator.
No cooler(except peltier) can cool below ambient or even close to it. A 20c. delta might be typical.
Ambient is not your room temperature, it is the temperature of the air that is blowing against the radiator. If the aio cooler is not mounted in front to use fresh room air your cpu temperatures will be higher.

In time, your room will heat up from the heat given off by the pc.
This will increase your ambient temperature.

The best you can do is to open a window so the heat can flow out of the room.

Hey there,

Have you tried Eco Mode? It will affect the multi scores but keeps single core pretty much on the same level.

You can also reduce PPT, TDC and EDC values lower, and test with each change of those. Lowering PPT, TDC and EDC should help.

Currently I am using that PBO thermal limit: 75C
I have tested with and without PBO somehow its better than stock when it comes to temps.
So, if it goes up to 85c for spikes and and if stays at 77 to 82C its normal it wont affect longevity.
Front three and side two are intakes: Front PWM 60CFM side fixed rpm IDK whats the CFM rating it has.

 

[DSzymborski]

Are you sure those are front intake fans? Could be the lighting and angle, but that looks like the front of the fan in the camera view, which would make those front fans exhausts.

That's the important take-away: Ryzen 5000 CPU's are designed to run in the 80-90C range with full expected design life. Of course you want it to run cooler if you can because it's pulling back performance when temperature is above 75C or so but there is not much you can do about it with a high ambient environment.
