Anyone try a push/pull on a water cooler?

i saw these fans, and it sounded interesting reading the write up on them, how they are paired to cancel out noise and vibration. (i found them cheaper, but can't find the link) So here they are in case anyone wants to read about them

I know people do push/pull on air coolers, but does anyone have experience with it on a water cooler? My down low airflow and airflow over all isn't that great in the case, due to the layout and items inside the case, it's more for an Air cooled set up. But the ram block with 4 sticks makes the air coolers i was looking at unable to work. I was considering modding the case and adding a fan bellow the vid card, but that would make all the other slots obsolete. I'm not using them now, but this comp will be going into the locked/back-up realm in the next year, and i don't think i want to limit it in that way.

So i was thinking, doing a double pull, with a single pusher on the top where airflow is best. I realize i can do some testing but does anyone have any experience with this? I'm gonna just add some the fans in normal config and check temps, but it is something i want to play around with.

My main Q on this subject is the Power config. i have two power slots to use on the board, but adding the third fan means a spliter. Would you use the spliter on the push/pull OR on both pulls, and then have the pusher separate? My thinking is split the pull, then tweak the push.

Just get a PWM Fan Hub

push or pull vs push+pull is little difference on most setups
if the rad is thick or the fans are not high static pressure push+pull will help

most fan headers are good for around 1-2a
that fan is 0.13a, you can put 4-6 fans on the single header using an adapter or splitter

*note the rpm/sense line will only report the speed of one fan, but the pwn control will control all of them

Push + Pull not really worth it. Some people like to spend the money for extra bells & whistles, but trust me if the money matters, a couple RGB Fans alone could nearly be enough to buy another SSD or put at least towards hardware that would help you more, like towards your CPU or GPU perhaps.

Look up in-depth reviews and see which AIO as well as what Case Fans would be good for both high static pressure + high airflow without tons of db noise; like nothing above 32db; and buy a Case that offers air filters all throughout the case where intakes are concerned.

When you use an AIO, all of the fans it comes with should be power off of the pump via a single SATA power connection. That fan header is usually just for the Pump. Then control the fans via BIOS PWM RPM settings; or via OS Software.

Don't use any splitters with an AIO to Motherboard; however that is fine where Case Fans are concerned, as long the fans have the same power + rpm range, controlling one header would then change the speed of any connected fan; such as having 2x fans per header via fan splitter which is fine as long as not going above approx 1.2-1.5 amps per header.

Right, that is why i was thinking to put it on then pullers, as they are the tuned fans, then adjust the single. It's basically the case set up, has the PS and HDD block down low, so it blocks the entire lower part of the rad, so i can't get use it in push mode, as i think push is a bit more efficient. On top of that the GPU, blocks the top 2 fans, from getting much air to the rad in the first place.

I don't think it's a waste of money to buy good fans, I can always yank them and use them in my next build which is happening. This comp runs just fine in Non-OC mode, i'm just trying to stretch it a bit further. with end of life coming on win 10, and the 1060, it's days are numbered anyway.

.

The cooler i have, has the pump connected to the AIO, then another connected to the RPG, (which i never got working right, as i don't think the connector is right for my board), and the fan's to a 4 pin according to the directions anyway. It does have a sata connector, but that's on the RGB line. It's a Cooler master 240L i think

I don't understand. You said pump connects to AIO?

An AIO = Pump + Rad Fans; hence All in One.

Yes usually there is a RPM fan connection and no power; the power comes from SATA power on most AIO. The Motherboard or OS Software controls the whole AIO through the fan header, or via USB.

That's not the way this one works Cooler master 240L. You plug in the pump to the AIO, it's a 3 pin, Off the pump has one lead which goes to RGB, the fans are 4 pin that connect to the board, then split to each fan.

Fun fact, i watched a vid to make sure i had it right, and saw a Sata option for the RGB on the pump, because my RGB header on my MB, does not fit right and won't work to power it.. So yay for that. When the new fan's come i'm gonna try to fix that. :)

Ok then what do the instructions say to do? Plug that into CPU or Pump MB header?

If it includes a method to split all the fans that to make it easier for ITX and MATX boards and thus controlling one fan rpm controls them all

Push pull will make all but no difference on an aio radiator they are simply not thick enough nor do they have the fin density to need it.

Most aio rads are between 20 to 30mm thick, really you only need push pull at 60mm, 45mm is fine with Judy one set.

This is based off of a decade of custom loop watercooling plus using aio's etc.

Save the money gir a better cooler, cpu or gpu.

Push-pull will not make enough of a difference with most radiators not being thick enough, if you have a particularly thick rad then push-pull could help a little bit.
