H115i platinum push vs push-pull

[Mikealongo]

Hi everyone,

 

Next week i will be upgrading my cpu mobo and ram to the 3700x from amd and im also changing my old H115i for the new H115i platinum (I can't find the plate online for the AM4 and my brother will use the old one)

 

But a question came to my mind.

 

Should I use a Push config or a push-pull one?

 

Now im using push pull with 4 SP140 from corsair and its a little bit loud (and I have some problems connecting all the 4 fans, so they arnt rpm synced...)

I heard that ryzen is temperature dependent and i want to know what your opinion is:

 

Push with stock h115i platinum or push-pull withe the stock from the platinum and the SP140?

 

Thank you all

What is preventing you from syncing the fan speeds of the 4 SP140 fans?

If i recall correctly the fact that the 2 fans that came with the aio connects to a single fan header (like a splitter) and then to the cpu fan opt i think while the other two I connected to the modifier in the 760T i guess

 

The fact is that I don't know with the new mobo x570 strix gaming e (long name) if I can connect all the fans somehow and link them with ICue or the BIOS itself...

 

Or even if I should go push pull or only push!

I would get a fan cable splitter or hub and then run all four fans off of one header.

I cant help with your RGB issues, but push is better than pull, and push/pull is the most effective option. I had an H100 and ran 4x 120x38s on it at 7v for daily stuff, 12v for benching.

The fact is that i had those cabkes on my wishlist for years but while one of the ends has 4 connections and is PWM the other one isn't so tuns at max speed

My concerns begins with having different pairs of fans for the push pull the other is because i dont know if i can sync them when 2 are connected to the pump (and with their fan curve deppending on the liquid) with the other 2 attached to the motherboard

Is that possible?

What do you mean?  If it's PWM then it's PWM.  Not all of the cables in the splitter will have 4 pins, but that doesn't mean it isn't PWM.

 I watched a confusing video this morning wich says that ona of the ends only have 3 pins instead of 4 abd in the comments section someone makes that assumption. 

 

Lets make my scenario:

 

I have the 2 fan header from the pump, then I plug one novtua splitter in each header and I have then 4 of them

Will the 4 one run at same rpms? If icue want them to run at 1600 rpm will 4 of them at same rpms?

If yes, it will be great but i dont really know

You need to keep the same type of fans on one splitter if you want them to run it at the same RPM.

Yeah, if the pump has two headers then I'm assuming it was meant to control the original fans which means those two headers are going to run at the same speed.  So if you put a splitter on each of those headers than all four fans will run at the same speed.  They have to be the same fans though.

Well i just bought the splitter and a cuple of ML 140 (the basic grey ones).

Using a splitter per channel and ataching each side to each end it should work, doesn't it?

 

Thank you btw your the man!!

If you already had 4 matching fans why did you buy 2 more?

Because the 4 i have are the sp140s that in theory are louder than the ML 140s and the ML140s have RGB (not a big rbg fan, pun intended) so i bought another 2 MLs and i will give the old h115i with the SPs to my brother

 

Will work? xd

So you're going to have 4 matching fans?

I guess,

 

2 ML pro RGB 140 and 2 ML 140 (i guess that are matching?)

They are not.  They have differing speeds.  The Pro RGB go up to 1200 RPM and the plain ML 140 get up to 2000 RPM.

I guess that as long that i connect the lower one to the heather with the 4 pins it will make the fast one to sync? Or at least not excwed 1200 rpms

 

If not, i can mount the fastest ones to pull to help th pushing ones

If you're gonna have different speed fans then you'll want to use different fan headers for each set of fans (not both fan headers on the AIO) .  Then you can actually adjust each set of fans and monitor their actual speeds.  If you use both sets of fans on the same header then the speeds won't match up.  The header will supply a certain amount of power and the fans will respond differently.  

 

Using separate headers for the different sets of fans will allow you to tune each set of fans so they can actually work together.

You mean each set from a mother noard header and no one from the pump?

Then the fan curve wont be linked with the aio water temp, im wrong?

What happens if the fan speeds dosen't match? (Im really new to fan things, sorry)

[The Torrent]

I personally can’t see any point of doing push pull for a 3700x temps really ain’t gonna be a problem.

If you want it all to revolve around what your AIO software reports then you need 4 matching fans.  What I am talking about is using the motherboard headers which won't respond to your AIO software.

Because the noise level will be lower at the same temp

What is the best way to setup the fan curve? With the water in the aio or how?

And temp wise, what are the effect on having not matching fans?

The only 400-1200 on the ML lineup is the ML PRO RGB that increases the bulk (node, comander... wich implies another usb wich i don't have) all the ML runs 400-2000 

 

Edit:

Fun fact, in the details of the radiator the fan speed is 2000 rpm so now im so very much confused... XD 

 

Edit 2:

 

If the fans weren't the same rpm, I saw that I can adjust the curve for each channel. I guess that I could adjust each one to make them run at same speed

[The Torrent]

It’s literally so quiet anyway. I actually have one of my fans turned off lol

[nick name]

Yeah, I'm not sure what fans you have or bought so that makes sorting it more difficult.  If you're talking about the fans the AIO came with and those fans are listed to reach 2000 RPM on the product page then that should match with the fans you bought.  

 

And your AIO software may control the fans if they run off a motherboard header.  I've never used it before so there's a good chance I'm wrong on way or the other.  If all the fans run the same speed it may not matter though.  You should be able to use the two headers on the AIO to run all four with no issues.

Looks fine then i will do the four with the two AIO headers.

What i don't get is why the AIO fans are listed 2000 rpm while the same fans are listed 1200 rpm in other corsair page

 

Thank you
