PC running hot in room
Posted by Littledickbigspoon@reddit | buildapc | View on Reddit | 28 comments
Is there anything I'm im missing in my build here thats causing my PC to run so hot in my room?
I'm getting consistent temps for CPU at 50 degrees so at least thats not too bad but my room with my door open is cooking right now.
Heres my parts list, the only thing I can think of is the case is just dogshit for airflow?

Any help would be appreciated, and apologies if I've posted this incorrectly at all.

you should consider getting a 360mm aio , that will definitely improve temps. It fits in your case, i checked

Even if it lowered CPU temp, it would do nothing to lower temp of the room.
Adventurous_Chef7241@reddit
I thought about cpu temp. my mistake
9okm@reddit
No worries.
splepage@reddit
That wouldn't do anything.
Adventurous_Chef7241@reddit
I thought about CPU temp. My bad

If your temps are that low, and it warms up your room that just means your pc's cooling system is working as intended. Heat has to go somewhere, if you want a not so hot room, lower your fan curve profiles, so your pc will retain more heat, or better yet improve your room's cooling system (ventilation mostly)

Can you specify which temperatures you are concerned about? Have you seen something significant? Because a consistent 50degrees is nothing to be concerned about.
Littledickbigspoon@reddit (OP)
CPU's been running at 51 degrees and gpu at 55 while gaming, its more so the entire PC is generating more heat than my previous build, maybe I'm being overly concerned.
splepage@reddit
The temperature of your PC components is not directly related to the temperature of the room.
The amount of power (Watts) that the PC uses is what heats up your room.
A PC with a 90C CPU and GPU that's using a total of 600W is producing the same hear as a PC that's running those same components at 50C and using 600W.
esorgem@reddit
55 degrees while gaming is crazy good temps. There's definitely nothing to be worried about if that's the case. Sounds more like you need to make your room cooler for your sake than your PC's.
syktunc@reddit
because your new components are probably using more power... basic thermodynamics
9okm@reddit
What were the specs of your old system?
DarkPhoenix1515@reddit
I don't think you understand what "cooling a pc" means. It means it will take the heat from components and pc tower INTO your room, thus cooking you.
Having no way to cool your room is going to be a curse that gets worse the more powerful (and power hungry) your pc is.
If having cooling in your room is not an option, consider more power efficient parts or moving the tower in a different room.

The airflow in ypur room traps heat. Get a decent fan and experiment with placing it in different locations.

Considering that even with 100% case fans speed with \~22°C ambient the 5080 would end up at full utilisation around 7x°C as shown in every GPU review. One example here https://www.igorslab.de/en/nvidia-geforce-rtx-5080-founders-edition-im-test-geforce-rtx-4080-ti-mit-blackwell-genen/12/
=> Your GPU temps suggest you dont even utilize the GPU in its higher wattage range and you dont even experience the full impact to your ambient air temperature with a \~500W gaming system.
It could be a lot worse with a game that actually utilizes your hardware.

Solutions for your room heat up issue (outside of AC):

The 98XX3D can suck down 200+ watts of power. Some people report spikes to 300+ watts.
For the video card factory OC models suck down 370 – 420 Watts.
All those watts get converted into heat. It has to go somewhere.
Heat sinks conduct heat away from the components. That heat gets pumped out into the room. It's up to you to cool the room for your 600-watt-ish space heater we affectionately call a computer.
FYI. The highest cost for Data Centres is electricity and cooling. Not the actual servers.

You have high end parts that uses more power and so generate more heat. Not much you can do other than power limit or undervolt your components and hope they can run cooler, but not sure how much impact that would bring.

Just like the airflow for your PC, your room also need a air flow. Probably have trap heat in your room and just having the door open is not enough. Best to have a window open for air circulation. And cleaning up your room helps. Also having a oscillating fan in the room helps.

A gaming pc will generate a lot of heat in an enclosed room when at load gaming. Not much you can do besides get an air conditioner.
deeznutz133769@reddit
A new case isn't going to do anything for you whatsoever... a case just MOVES the heat from the components to your room. If it's heating up the room, that means its working.
The more high-powered the components, the more it's going to cook your room. A budget cpu with a 5600 isn't going to heat your room up that much. A 14900k with a 5090 with an AAA game running or running benchmark software is going to heat up your room dramatically.
Best thing you can do if you have AC is to have a fan blowing out of your room. Bonus if there are two doors and you have another one (from a cooler room) blowing inside.

50 deg is not a bad temp for a cpu
darvo110@reddit
Temperature of the chip and temperature of the room don’t have much in common.
AM5 chips run hot and idling at 50C is normal. That doesn’t necessarily mean it will make your room hotter. What matters for that is the total wattage your computer is generating and outputting as heat into your room. If it’s idling at 100W that’s the same as one or two incandescent light bulbs. Not gonna have a substantial impact. Of course when you’re actually running games it’s much higher and will impact room temp.

Hmm I have the EXACT cooler and processor as you . But I do have 6 intake fans and 2 exhaust . And 4 mo ster air movers too on the Asus Matrix 5090 . I never get above 67C on the CPU . In 4k .
With that noctua . Don't be scared to turn the curve up wild if you wish . Its freaking silent no matter what .
My last PC I used the u95 which is a single noctua 95mm fan . And I juat set it to like 70 - 100% and silent as all hell cooled my 7800X3D for idk almost 3 years . Now im using the bigger noctua that you have because I have more room. IMHO its the best cooler out . Better then the guy below recommending a 360 radiator. You do not need that . Play with your fan curves . Your using a 120 watt cpu . It should not warm the room up like a 13 or 14 Gen intel would. Don't be scared to get the fans spinning . Intake and exhaust

AM5 idles warm. Normal.
Littledickbigspoon@reddit (OP)
Noticed that, I've been trying to make sure to shut it down when I'm out so as to not walk into a sauna lol
FlatImpact4554@reddit
Same I always shut down
9okm@reddit
This PC at idle won’t generate much heat. Only at load would it be a concern.
