4080 - water cooling options?

My office is in my loft...which gets a tad warm to say the least! I am looking at A/C, but even in winter the 4080 starts taking off (particularly running BF6).

There is no other water cooling in the PC and I've maxed out the fans I can fit in there. I've got a spare sat on top of it to try help, but it hasn't done a thing.

TIA!
 
Water cooling will heat the room more efficiently, so possibly not the best solution depending on quickly the room becomes toasty.

If you just want lower noise levels then a 120.2 or larger loop would easily deal with a 4080 and CPU.
 
This is the sort of situation that would seriously get me looking at putting the PC somewhere else in the house and streaming to your office location, during the summer at least.
 
What brand/model is it? I thought the 40 series were meant to run pretty cool/quiet.

May need a repaste?
It's an ASUS 4080 16GB TUF Gaming OC.

I'm not sure where I could put it though - house isn't very big, only a 2 bed bungalow and fairly open plan downstairs. There is a side bit to the loft that has my solar stuff and hot water tank in, but it gets REALLY hot in there - it's also only about 10ft to my right...
Portable aircon unit would probably be a better and more useful investment tbh
I have one of these, but it's as noisy (if not more) than the card...!
 
Air conditioning the loft would be your best bet, watercooling can only do so much when the ambient temperature is high. It will also add to the heat already in the loft.

If temps are still high when temps are low you may need to repaste and/or mount the gpu block. Or add an additional or better radiator.

What radiator do you have?

It's this loud year round though, but the loft is probably say 20 in winter (once heating has pushed it up) and then it has reach very high 20s, even low 30s.

The radiator is the stock one...

If you have a presumably enclosed bit up there next to where you are then the next best thing would be to put a radbox in that enclosed space and run tubes back to your PC. Yeah it will get even hotter in that room, but it your actual hot water tank is in there it may be beneficial for that slightly. The water cooling won't be quite as efficient when compared to true ambient temps surrounding the rad, but as long as the air temp is lower than the water temp there will be a net heat transfer. Best if you could vent the radbox fans outside somehow. If it like absolutely *sweltering* in there though then maybe you really are knackered.

And by "radiator is the stock one" I guess you meant the cooler is the stock one, and you don't have any water cooling on either cpu or gpu.

Correct - no water cooling there at all at the moment. I do actually have an AIO CPU cooler that I could put on...

The ASUS 4080 16GB TUF Gaming OC is an air cooled card so does not have a radiator. Assume you just mean the stock air cooler.

Your OP kinda implied you had some form of watercooling already but if you don't I dont think you would get much benefit from switching to watercooling until get sort the loft temperature out first. Once you have done that you might not need to upgrade the cooling.

If you are just concerned with noise rather than heat you can experiement with fan curves.

Yes, sorry I meant I have no water cooling full stop. As in if I watercooled the 4080, the rest of the PC is on air. And yes, I mean the stock air cooler.

The thing is, it does it in winter as well, so I'm not convinced this is an ambient temp issue...

You would need to do some testing when temps were normal to see how bad it is. If you are just going off noise then it could be a bad fan curve if you know what I mean.

If its overheating then repasting the 4080 GPU and replacing the thermal pads will probably help.
 
This maybe a bad idea for you but you just watercool the gpu and have the radiator right next to the windows or something with the pipes leading out of the pc case to the radiator. If not by a windows could be put by a vent? You could even set it up for the cpu aswell and get a little bit of a bigger radiator. I have a alphacool nexxxos 9x120mm radiator and when im all set up I hope to put it by the vent of the room out of the way of my pc.

If your not arsed about aesthetics you could just get the EKWB ZMT tubing. Its apparently the least leechy tubing out there and is black.

Depending on how hot the loft gets and buildings structure, a simple AC system might not be the best idea. The dew point could be in the single digits and you might end up with damp building up in the loft.
 
Have you bothered to undervolt the card yet? The 4080's are pretty receptive to it.

You can usually manage around 20-25% lower power draw with no real performance loss, that's where I would start, that'd net you a good 10-15c lower temps on the GPU.

No, I'm going to look into this as a first step as I've seen lower volts and higher FPS results!
