How fast should a pump spin

[Agilolfinger]

Hello,

 

I just filled up my newly installed custom loop today.

It's vased on two Aquacool Waterblocks for CPU and GPU. A 360mm Radiator and a 240mm Radiator. Combined with a EK Pump/Res Combo.

 

When I first filled up the loop and started the pc nothing really happened. So I went into the BIOS and set the Sys_Fan_Pump Header to Full Speed to the loop will be filled.

 

But when everything is running fine. What are the Best BIOS settings for the pump.

 

50% speed at idle 100% speed, if I reach e.g. 70°?

 

Is there a Best Practice?

 

 

Full Config:

Ryzen 5 2600

RTX 3060 Ti

Aorus X470 Ultra Gaming

Patriot Viper RAM 16GB@3200MHz

 

Thank you!

That is a lot of cooling for a R5 2600, lol.

 

But for normal use, you can likely set it to 25 or 30% I believe I have my EK D5 pump set to ~1500 RPM when things are at idle, and have it ramp up to 3500 rpm when under load. I think... I could be a bit off, its been a while since I looked. But with that much rad space for those components, you will have no issues keeping things cool. You won't need much pump speed, and fan RPM will be able to stay very low which is the main advantage of custom loops.

 

In game load, my system (10900k OC to 5.1 all core, 2080 @ 2025 MHz) I run the fans at ~900 RPM which you basically can't hear, especially with any amount of game volume via speakers of headphones), and CPU stays under 60-65c, and GPU is under 50c. I do have a bit more rad space, but I have more wattage to deal with cooling, so you will be in great shape (honestly, you spent too much on cooling vs the parts in your PC, your custom loop likely cost 500+ dollars, mine was over 700, BUT, you can continually reuse the rads, fans, pump, res and fittings, so over time the cost does average out as it will last more then just this one build.)

You are right. The cooling is a bit over the top for my components.

 

The reason I built this loop was a mix of personal interest and being annoyed by the bad performance and high noise of the Founders Edition Cooling.

And I thougt if I watercool my GPU, I will watercool the CPU aswell.

I also thought I have the space for both rads so why don't buy both. 

 

In total i spent about 460€ which are about 530 USD so your guess was very good.

But as you said at some time I will upgrade my CPU and I can use the cooler again. (Until AMD changes to AM5)

 

But back to my question.

Thank you for sharing your setting with me. I will refer to them when I set up my pump and fan speeds properly.

With how over kill your cooling solution is for your specs, I'm assuming this is mostly for optimizing noise. I'd start with setting you pump speed really low maybe 10%. Adjust your fans speed to the max speed based on noise for your liking. This will give you your max fan speed under load.

 

I'd then adjust your pump speed to 100%. With a load I'd then start Dialing down the pump speed to the most minimum noise level without an increase to temperature. 

 

This should bring you to a good ballpark and be able to fine fine tune further.

best way to find out for me, is to run stress test (prime 95 small fft + unigine heaven) for 30 mins

 

i set my d5 to static 60%, after adding 2 eiszapfen quick disconnect i set it to 70%

 

that'll depend on your pump noise too

Keep lowering it until you can't hear it. As long as you have flow you're fine. Pump speed doesn't make a huge difference for thermals so I aim for acoustics.
