Adding a huge reservoir

[TheNaitsyrk]

Hello there,

 

I want to add a huge reservoir to my loop. 

 

The temps are excellent, and over the top but I think they rise too quickly.

 

If I added a huge reservoir, would it help?

 

I was thinking of adding another pump with bigger reservoir or just the reservoir.

Reservoir size won't make any difference to performance, positive or negative. It can make it a bit easier to fill the loop and top it off but that's it.

Would it help with temperatures rising a lot slower?

a big reservoir doesnt help, the reservoir would mean just more water to be cooled by the radiator

 

who does all the work is the radiator and the fans

 

perhaps what you can do is handle better airflow, that could control temperatures better, but since you gave 0 details, no idea what is best for you

Everything is in the sig.

 

I got 3000 RPM fans so I don't think it can get any better.

You would have more thermal mass so the coolant would change temp slower

3000 rpm all the time, you got deaf then!

 

airflow and low temperatures doesnt depend only on that, also in the amount of fans, internal flow, place where you put the radiator, if you put fans in push or pull, there is alot you can do to improve or to decrease performance

You should be aiming at lowering your deltaT. If you have a low DeltaT then we are talking temps rising by 3-5C from powered off to full load.

Only if your problem is airflow anyway.  Assuming that you change nothing about your system other than increase the size of the reservoir, yes, temperatures will increase slower when you first boot up the machine, but only because the water has more mass to absorb the energy as it passes over the chips and cycles back through the loop.  It's still going to hit that same load temperature, and it's going to take longer to cool down after the system starts to idle again.  So if it takes 10 minutes to hit the equilibrium load temperature from startup, adding a bigger reservoir might make it take 11 minutes instead.  But that won't change what the equilibrium temperature is.

 

The rate of air changes over the radiator and the rate of water changes over the radiator and the thermal conductivity between chip/waterblock and water/radiator are the real variables here.

It's not running at 3000 RPM lmao.

Ah okay, so I'd have to add another radiator which I can add. 

Temps are ultra low as is, just wanted to see if I can push it lower.
