Need suggestions for better cooling

[0binary1]

Living in a region close to the equator it's hard to get decent cooling for my rig. And if I add tasks that maxes out CPU and GPU at the same time, then my room feels like a furnace. With CPU >85C and GPU >65C I am looking for solutions that can cool down my CPU more efficiently. Currently using MSI AIO with 360mm rad.

 

With ambient temperature of 35C+ my idle CPU temp is over 50C. During winters (which seems to have skipped us in Mumbai this year) temps are around 33-40 on idle. Which is good because our winter temps are between 18-28 on average.

I'm looking for a solution where I can bring down the CPU temps below 40 at least.

Any suggestions?

 

CPU: Ryzen 5 3600X

GPU: ASUS ROG Strix 3070Ti OC

Mobo: MSI x570 A Pro

CPU Cooler: MSI MAG CoreLiquid 360mm Rad

 

Thanks!

Realistically, there likely isn’t much you can do. You will never be able to get heat producing devices down to be that close to the ambient temperature… if it’s 35c in your room, it’s unlikely the idle temp would ever be under 45 ish degrees. For how hot your ambient is, I am honestly surprised your GPU isn’t warmer.

 

All you can really do is try and undervolt your CPU some so it produces less heat, and hope that helps. AMD does pretty decent with this strategy. 
 

Also, something to remember, no matter what cooling solution you get, it won’t reduce the ambient temperature of the room; if your PC produces 300 watts of heat, a better heatsink will make the temperature of the parts lower, but that’s only because it’s doing a more efficient job of transferring the heat produced into the air in the room. The same heat is being generated either way, so the ambient room temperature will not be reduced with a better cooler. Just clarifying in case you didn’t know this.

undervolt your GPU and save, probably, 1/4 power (pretty easy)

[Ralfi]

Hey there. What case are you using? Does it have a solid or mesh front?

[leclod]

Also you probably got 3 intake fans and 4 outtake. That's negative pressure, not great for dust.

I'd think about ditching that rear exhaust fan that steals "cool" air from the cpu AIO

radiators should be intake.

that AIO is trash. 

[IkeaGnome]

Something to keep in mind with cooling. Your computer isn't going to put out less heat by adding more fans and it running cooler, it's going to be putting out more heat. The components will produce the same amount of heat unless you under volt. Running cooler just means you're pushing that heat out quicker.

@LIGISTX Ah that's what I was afraid of!  My GPU is cooler probably because of the fan setup.

 

The front fans are intake and the remaining 4 are exhaust which was done to keep the GPU cooler (CPU costs less than GPU ). @leclod Correct my if I'm wrong but I was under the impression -ve pressure is better. Maybe I misunderstood JayzTwoCents?  I clean it out once every two weeks and recently just 2 days before the original post.

 

@IkeaGnome @LIGISTX

Yeah I don't expect my PC to cool down the room, only to run cooler that the current setup . I understand the confusion because of what I said about room being like furnace. Got the point and I didn't think it through when I wrote that line. I ran a test last night bringing down ambient to 24C and even though my GPU came down to 33C the CPU hovered around 43-45C. I know I have seen my CPU temps in the low 30C range when my AIO was new. So I'm leaning towards the AIO not being as efficient anymore even though it's only been less than 2 years since I bought it. Maybe applying a fresh coat of thermal compound is all it needs?

 

@leclod @LIGISTX

I did under-volt the CPU to run at 2.5GHz (0.98V I think) but did not like the results, lost the snappiness. I did it earlier because after the Win11 update it always kept boosting to 4Ghz+ even w/o overclocking. Yes OCGenie was on but it didn't happen on Win10. Now it's set at 1.1V and 3.8GHz which is closer to the default for this CPU. I think I'll tune in down a bit more (1V and 3GHz probably).

 

@NorKris I agree but I was more focused on creating -ve pressure. As for the AIO I am starting to think the same. Do you have any suggestions? I am thinking of switching to air cooling. Noctua NH-D15 black, maybe. I'll lose most of the RGB but I'm fine with that!  

 

 

@Ralfi It's a CM MasterBox MB511 with fine mesh front intakes. Focused on good airflow when building it because of how hot it can get here in Mumbai. Last years high was 45C 

 

To all, I did not expect so many responses to my first post. Thank you all for helping me with this.

I would love to contribute as a team once I can get better cooling . I don't think Folding has an option to use 100% GPU and 50% CPU. Maybe not how it works.

I doubt it needs new TIM (thermal interface material). TIM lasts for a long time... Was it in the low 30's when the ambient temps were lower? Ambient temps are directly proportional to the temps you see on your components. 

 

As others said, you could put the AIO as intake to get cooler air, but it probably will not make much of a difference.

Yeah the ambient temps were lower around 23-25C. That's what I' concerned about; the gap between CPU temp and ambient temp was not this high since I got the AIO.

Right now it's 37C ambient and the CPU temp is hovering around 53-55C with just 6 chrome tabs open. CPU load is <10% @ 3.6GHz. GPU is doing much better at 44C only 7C above ambient.

[leclod]

Undervolting doesn't mean underclocking, just undervolting. The same performance but less power (Watts).

You didn't say if you undervolted your gpu (my RTX3060 went from 170W to 130W)

 

Negative pressure is bad for dust mainly. That "negative" air isn't filtered.

 

I doubt the gpu knows the rear exhaust fan is intented for it.

Oh ok. Just after my last reply I undervolted the CPU to 1V from 1.1V and also changed brought down the clocks to 3GHz. I thought bringing down the clocks along with volts is required to maintain smooth operation. Not an expert in this. Just learning from videos.

And no, have not touched my GPU. I have left it alone as I got it only less than 5 months ago after a long wait and I am scared of damaging it. Playing GoW 2018 ultra at 1440p it's temp does not go above 70C.

 

I think the rear exhaust pushes out GPU heat mostly because the CPU AIO fans are exhaust. I am aware with this config the CPU will get the hotter air thrown out by the GPU but it used to be better which is why I'm thinking if it's an AIO issue.
 

I'll take your suggestion and undervolt it further to 0.98V and leave the clocks at 3GHz.

 

Thanks! 

[leclod]

Leave your cpu for now and focus on your gpu. Your gpu doesn't get too hot because it has a big cooler.

You won't hurt your gpu by undervolting.

Here's a short tutorial with MSI Afterburner (maybe start with 0.9V or higher, not 0.85 straightaway and check if it's stable with benchmark/stresstest)

 

 

 

[0binary1]

OK, so I undervolted the GPU from 1081V to 950V. The GPU temp has gone down by a degree to 43C. On 99% load in FurMark the temps are below 75C which is close to what was earlier. I was expecting a bit more difference or maybe I did something wrong.

[0binary1]

Sorry, ignore the previous one. The latest curve is 1935MHz at 925mV.

 

UPDATE: Tried 900mV and furMark crashed. So I guess 925 is where I should stop.

You could probably try 920mV and 915mV, usually 5mV steps   (or 910mV at 1900MHz)

But fair enough, thank you for indulging.

 

About your temps, what was the previous full power Voltage ?

It makes a big difference in my computer (from 1V to 0.85V / 170W to 130W)

My 3060 has only one fan and it ramps up to 1430rpm in a 20mn stresstest, which is still quiet for a decent amount of power (my room temps are lower than yours though)

Afterburner can display the Watts, can you tell, from .... W to ..... W ?

 

He does 1900MHz at 0.9V or 1800MHz at 0.85V

 

[freeagent]

I would start from scratch.

 

High airflow case, like a Torrent Compact, A good cooler like a PA120, or FC140, and maybe a couple of decent fans for the floor of the case, and one for exhaust.

 

That way you can run full power on everything, and get full performance out of your components.

I wouldn't sweat the thermals too much 3000x series CPU's are rated to a 95C's cap  and a GPU is sitting comfortably BELOW the 75C where newer NVIDA cards tend to Thermal Throttle.

CPU temps seem unusually high.

The Msi CoreLiquid series has had some recalls due to sediment buildup issues.

Have you contacted Msi about this? They may send you a replacement cooler.

[leclod]

Just thought of something : maybe your system was thermalthrottling ! so undervolting might result in the same high temps but at higher performance.

 

Only solution would then be underclocking. And it doesn't hurt that much, underclocking little saves power fast.

might wanna change those MSi coolers from Tier 1 to Tier 7
