Question requesting help with possible cpu overheating

[vramch]

I recently built a new PC -3 days ago.

Mainboard Gigabyte X670E Aorus Elite
CPU - Ryzen 7950X3D
Cooler - ARCTIC Liquid Freezer II 360
Case - BeQuiet 801 Base
GPU - Radeon 9700 XTX
RAM - Kingston 64GB
Storage - Kingston 2TB NVMe

After building i noticed the idle temps were between 40-44C

I thought this was a bit high so i did some reading and came across several threads saying the case fans should blow in to create a positive pressure in the case. I have the fans on the Arctic blowing out the top of the case. Today i reversed the front and rear fans on the BeQuiet to blow inwards, and the temps now idle at 45-52.
I downloaded cinebench 2024 and ran a cpu test and the highest temp was 86C

should i be worried about these temps and is there anything i can do to lower the idle temps? 45-52 seems high to me. I did make sure the cooler was installed using the offset mounts.

any help or suggestions is appreciated

thanks!

There is a bit of a catch 22 where it comes to AIO and a high powered video card. If you put the AIO cooler on the front with the fans pulling in air, then the CPU gets the benefit of the cool air while the video card is using air already warmed. If you top exhaust your AIO then it takes the penalty from the graphics card.

Your highest temp isn't worrisome but would consider setting it up for the coolest idle temps.

thanks very much for the advice! I did what you suggested
i moved the fans on the front of the case to the top and set them as intake. the fan on the back of the case is exhaust.

i moved the cooler to the front of the case and set those fans to intake.

the idle temps went down slightly, 42-46, i saw it hit 58 on boot.

i did another run of Cinebench 10 mins cpu test. temps were better, from 78-82C. are idle temps in the 40's - low 50's average for this CPU? this is my first AMD CPU and GPU so i am not sure what to expect from it.

I suggest moving the cooler back to the top and set them to exhaust. Rear case fan should remain as exhaust. Front fans set to intake. Hope this helps.

thanks. i'll give this a try tomorrow. too tired tonight. I noticed since i moved the Arctic to the front and set it to intake the GPU is now at 43C on idle. it used to be 33C on idle. thats a large jump. Is there a benefit to the radiator being on top or front? instead of moving it to the top, would it have the same effect if I just reversed the fans on the cooler (exhaust) and leave it on the front?

Cpu temperatures sound good, at least.

You'll win and lose regardless of whatever you do. Both the cpu and gpu have their boost curves tied to temperature - though it isn't the only factor.
-majority of the axial fan gpu coolers recirculate some of their own waste heat. A front intake cpu AIO isn't going to add that much more. The real catch-22 is the air resistance the radiator adds there. To get around this, fan rpm is raised at the tradeoff of noise level. The performance penalty incurred with the rad and fans positioned against an open mesh panel is small, that it may not be necessary to increase fan rpm. If the panel isn't meshed, I wouldn't recommend installing a radiator there.

-front exhaust cpu AIO. This one is very situational. I guess it's like one of those 90 degree or inverted setups. Case ambient temperature is the main air source for the cooler, further warmed up by the gpu cooler.

-top exhaust cpu AIO. Best for gpu operating thermals, worst for the cpu cooler. The case ambient is the main air source.

-top intake cpu AIO. Not recommended, because it basically makes the gpu cooler recirculate even more of its own exhaust. The thing about rads and mesh panels still stands.

Case - BeQuiet 801 Base

Silent Base 801?
Cases like this, are perhaps by default, optimal for negative pressure. Trying to positive pressure this could do more harm than good.

thank you for this - it explains a lot - i am not sure how to manage the AIO fans, there was no software supplied with the product and i can not find any on the manuf website. i know its working, i can see the fans spinning. just not sure how fast its ramping up as temp's go higher.

and i did make a mistake its the SIlent Base 802. i will check into this, but it does make sense. the case fans were all set to exhaust, so i may change it back.

It seems the major consideration is the hot air - in thinking about this why not channel it out? I can put a exhaust fan on the top of the case, and i am pretty sure i can fashion some kind of bracket which channels the incoming air from the CPU Cooler directly to that fan. Would this be worth doing? i think i'll give it a go - possibly try to do the same to the GPU exhaust air.

So a bit of an update. I was digging around and found i did not have the AMD Adrenaline software installed. After installing it i realized the GPU fan was not set to start spinning until the temp hit 60C. that's a bit insane to me. I played with the fan curve and now my GPU sits at a 28C on idle. I found a software called FanControl ( https://github.com/Rem0o/FanControl.Releases )
It detected all the fans but could not control the GPU or the 4 case fans (these are controlled via a PCB managed by the case ) It can control the Arctic! so now i have the CPU idling at 40-42C. I will still mess around with the airflow in the case and see if i can improve it in any way.

Ah, that. If I remember right, and you hooked up the AIO's cables as instructed in the manual, then the fans run slave to the pump rpm(in percents). You'll have to plug the fan cables in a different header to see and control them separately. You can then set the curves through bios.

and i did make a mistake its the SIlent Base 802.

Ok. This changes things quite a bit, as this model supplies optional top and front mesh panels. The question is whether you personally want to use those panels or not. Recall what I posted about installing a rad and its fans against a meshed and non-meshed panel. Also, depending on how you set it up, and your personal fan curves, you should be able to positive pressure in the SB 802.

It seems the major consideration is the hot air - in thinking about this why not channel it out?

Because, even if it's another device's sloppy seconds, some preheated air is still better than none at all.

This makes complete sense now. I could not find an independent connector for the fans when i was setting this up. its powered by a single cable. OK i will either order or make a cable to power these fans separately.

the case came with solid panels installed, i guess to suppress noise. i changed them out to the mesh panels top and front. they do let quite a lot of air flow through as its not pressed up against the fans - there is about at least an inch between the fan and the mesh panel. To me it's still extremely quiet, and i have the fans running on the highest speed i can set via the case control.
