Water Cooling Basics: Fan Configuration

A general explanation of how to configure the fans in your custom loop

[@snrd]

Good call on recommending the Aquaero controllers. Running my loop with several water temperature sensors hooked up to my Aquaero LT 5. It's awesome that fans don't ramp up just because of a short cpu or gpu load.

Brilliant thanks you answered all my questions

[@Nxtgenpcs]

Great video/advice :)

[@v.aesthetic3764]

Thanks man

[@snrd]

Still using my Gentle Typhoons. Lov'em.

[@v.aesthetic3764]

Those are great fans!

i have a question if i have 2 pumps that are 2 pwm do i plug both to the cpu header with a splitter? or do i plug 1 into the cpu header and other to a different header on the board? to controll the speed of the pump

[@michaelkopec.5814]

Noctua NF-A12 or Noctua NF-F12 which one is better ? great video. Thank you.

I agree with most of this, however, CPU and GPU boost algorithms are partially based on component temps and it *IS* easier to get higher clocks out of cooler components even on cooling rigs that are above ambient. my 3700x for example will keep my clocks boosted up to 4.2ghz if i can keep the temps down below 60c, but going over that triggers automatic lowering of clocks. similar things happen on my 3090 at around the same range, so if i'm overclocking both cpu and gpu (as i would if i'm spending $1000+ on a custom liquid cooling setup) and i'm doing long duration workloads (for example say a multi-hour blender render with both cpu and gpu which is pretty common for me), keeping those temps in check is EXTREMELY important or you end up losing performance to the tune of roughly 10% and if you get into the 70-80 degree range on either, it can be as bad as losing 15% or so.

I was under the impression that if you don't have a fan connected to cpu fan header the PC won't boot?

[@y0nki]

Can you do a video on using a coolant temp sensor and configuring it with a motherboard?

[@v.aesthetic3764]

I will probably do a video like that at some point.

[@snrd]

Well it's pretty simple, just get a motherboard that has a temp sensor header and a bios that is capable of running the fans using the sensors value. Are there even motherboards that are capable of the latter?

[@y0nki]

Ok, so you pretty much need to get an aquaero for this?

[@snrd]

Ioannis Hronakis Pretty much. At least it makes upgrading hardware easier because you don't have to look after these special things (even most high end mainboards don't have temp headers). It may be possible with a software solution if you have a temp header but it only gets applied when the operating system is loaded and running. Also when running a custom loop, the last 50$ for an Aquaero shouldn't break the bank and should be considered.

[@y0nki]

Haha, yea, I'm not looking to cut corners, I just never used one. Don't you have to mount them somewhere? I'm actually going to replace my coolant with primochill vue, maybe I'll look into hooking up an acquero as well.

[@DJRanoia]

So coolant won’t break down at 70c right now I have 43c and 8 fans running at 900rpm should I raise my temp to get quieter?

[@v.aesthetic3764]

is that your coolant temp?
