How much heat does a 2080 put out on water?

[Taswell]

Does anyone know how much more heat the 2080 puts out than the 2070? Thinking about upgrading to a 2080 and wondering if it will heat saturate my loop.

 

Context:

I have a R6 2600X mostly stock and a 2070 in a Custom loop with 1 240mm standard thickness Radiator and 2 120mm fans on it. (the only fans in the system)

Case is a corsair crystal 280X, so not much room for more radiator space. I think I can fit another 120 but I don't think i can fit a fan on it.

 

I used battlefield V  on High 1440p for my temp benchmarks

2600x Never goes above 75C and hovers around 70C under load (keep in mind I have overdrive cranked in ryzen master so my power limits are really high)

2070 usually static at 80-82 under load because of GPU boost or whatever

 

My concern is that a 2080 is going to drive my CPU temps to high 80s and 90s? How much more heat does a 2080 put out?

 

(I attached a photo for more context)

a founders edition 2070 has a TDP of 175 watts, a founders 2080 has a tdp of about 215 from what google could tell me.

so that's a possible 40 Watt difference. so yeah, your temps will rise a bit. take this with a grain of salt tough, as tdp ratings do not really directly translate to temperature differences.

 

your 240 rad should be enough to cool the specs you have tough. i'm running hotter hardware on pretty much less rad space in my main rig, tough i do have more airflow through those rads.

i think that if you can maybe add more fans on the radiator and go push/pull you might see a better temp improvement over just adding another rad without fans, but this is pure speculation.

What are your water temps?

 

IMHO you are already at about the max a standard 240 is capable of cooling.

I thought of adding more fans the problem is that I only have 1 more fan header on my dog shit motherboard (Insert regret here, asus b450 TUF)

 

I know I am pretty close to My thermal limit but I don't know how many "theoretical" watts of cooling I have VS what I would need.

sadly there's no real answer to that without measuring your system specifics.

 

the thermal dissipation of a given radiator is dependant on a lot of stuff. for example:

 

if you have a 120mm radiator, and we give it a theoretical dissipation of 200 watts at peak performance, it would only behave like that in it's peak performance state. so with a given amount of airflow and a given amount of fluid flowing through it. if you change any of those variables the dissipation rating of the radiator changes. so if you run your pump at a lower speed, or your fans, or even use a different fluid that is thicker or can absorb less heat you arn't going to get peak performance out of your radiator.

 

now you also need to keep in mind that even a slight overclock on your hardware pushes a lot more heat into your cooling system. so eventough a 240 rad should be enough for your hardware when it is running stock, when you overclock it you might need more cooling real soon.

 

all in all your system is definitely at the max as it is now, you can simply see that by looking at the thermals. tough getting better cooling would require you to change any of the variables the change the tdp of your cooling system.

so either you crank the current system with more airflow, more fluid flow and maybe even a better fluid (tho admittedly that won't change too much), or you expand on the system by adding more radiator space, or you drop the overclocks on your system to push less heat.
