AIO liquid cooler makes my room uncomfortably hot - wondering if I should go back to air cooling

[Jacky60]

Appreciate the responses guys. The CPU is a Ryzen 7 7800X3D and the GPU is a RTX 4070 Super. I previously had an Intel i7-8700k and RTX 2070 Super. I have noticed that the CPU runs noticeably hotter when idle, and also when under load, compared to the Intel. With the 7800X3D, CPU idle temps are around 53c, rising to 70-75c when playing games. I'm using the included L-Connect software to control the fan speed as I don't like using Armoury Crate (it's known for being bloatware). Not sure why the idle temps are so high as I've seen comments saying it should be around 40-45c.

Using same CPU my gaming temps are near your idle temps. Gaming 55-60C using Peerless Assassin 120 on 7800X3D, Regardless of how you cool the CPU the same amount of energy as heat will be released into the room whether AIO or air cooler.

You should undervolt your CPU. Many Ryzens handle undervolts quite well, and this can lower the power draw by a noticeable margin. Nothing groundbreaking, but it's basically free "cooling". Likewise, you could undervolt and power limit your card. That's how you get components to draw less power. You can undervolt to a certain extent and lower power draw without sacrificing performance. You can go even further and sacrifice some performance for even better efficiency and lower power. As others have pointed out, it's the power draw, not the cooling, that fundamentally results in your room heating up. The power drawn generates heat, and your cooler merely exhausts that heat to your case, where the case fans will exhaust it right into your room. An AIO will do this faster than an air cooler, but over a longer amount of time both will raise the ambient room temperature by about the same amount given the same power draw.

As already mentioned Undervolt of CPU and GPU will make a huge impact, if done correctly usually yields lower temps and slight increase in performance, in addition to this you could setup a more aggressive fan curve to keep temps even lower, reducing heat given off into your room.

I notice the same, it’s like stepping off the plane walking into the room

Honestly IMO you're not going to make much difference to the room temps even if you undervolt everything in the pc, it's still going to kick all the heat out into the room. Don't get me wrong, yes rooms can get unbearably hot but imo +7C isn't that bad, I've seen +10-15C over outside temps in summer.... and I've capped my max temps in my bios so they don't go that hot as well....

Only real way you're going to cool a room down with a pc going in hot weather is either cool the room with something like air con or figure a way to divert all the heat out of the room to begin with.

The real issue is extracting heat from the room rather than the pc.

You could also underclock and/or power limit. 300W GPUs nowadays can shed 80-ish watts with only minor performance loss if you couple that with an undervolt. You can go 100-120 if you are willing to sacrifice more performance. That's enough to where it could make a difference. Though I do agree, air con is the best solution. There's just nothing quite like it.
