i'm going to put my H100i back into my pc and have heard that push/pull is a good way of keeping the radiator cool. without sounding like a complete idiot, can someone explain to me the principal? do the lower fans push and the upper fans pull (exhaust)? is this efficient?
Push/Pull
- Thread starter stujim
- Start date
just watched a video on the linustechtips channel, and he suggested that pull (via the top) is better and use the rear fan to exhaust the heat. I've got two be Quiet! silent wings 2 that are spare, would these be adequate to cool the rad? or would Noctua NF-F12 PWM 120mm Focused Flow PWM Cooling Fan be a better idea?

Push/Pull setup can get the radiator to have a lot of dust sitting on it in shorter times in a lot of situations.
My set up it:
4 case side fans pushing air into the case (All running at 7V)
1 front fan pushing air into the case onto the hard drives (7V)
1 exhaust fan at the back on 12V
H100i 2 fans on bottom side of radiator pushing air up onto the radiator, this is grabbing the new, fresh, cool air that is being pushed into the case by the 4 side fans.
Corsair link is linked with h100i with custom curves, so fan speed of both fans for h100i will increase at different temperature increments

How do you get your fans running at 7V? i will probably have the fans for the rad, connected to the motherboard and use Thermal Radar 2 to control them, also use it to control the pump. at the moment i have 2 silent wings pushing air in at the front (middle cage removed) 2 blowing in at the top and one exhaust at the rear. Just bought 2 Noctua NF-F12 which i will use for the rad when i install it. i have two slots in the left panel window that can have fans attached to it (my case is a Corsair Vengeance C70) so i may use the 2 silent wings that are currently in the top of the case.

What I do it I have all 4 side fans going into 4 wires that decrease the 7v from 12v (wires cam with my aerocool shark fans, can buy them separate) then these voltage adapters are also going into my fan control on my case, where 2 fans get controller by one controller knob. When I put fan speed up using fan controller on case I think they go back up RP 12v at full instead of 17v at full.
But I'm not sure what the voltage differences are when the fan controllers get used, I don't know myself, I just know it increases the speed when I use it, not sure what voltage the fan controller can get the fans up to
Btw you sound like you have a good setup for the fans so it's UK to you, maybe try it with push/pull and see what it's like with the dust clog up, it might not affect yours, I've only ever tried pushing air up form inside the case

i have seen a video on youtube, linustechtips, where he said it is better to have the fans for the rad, drawing in air, rather than pushing it up from inside. But each system is different i suppose, due to ambient temps, hardware that is installed, fan positions etc.i'll try his suggestion first, just to see how the temps are doing. What do you reckon about the fans for the side panel? both intake, or one intake the other exhaust? This is the first time i have really messed around with fan positioning etc. I currently have a dark rock pro 3 cooler, but my case is so tight due to only having a micro atx board, that the huge heatsink on the cooler is wider than my gtx 980 and sits only about 15 to 20mm above the backplate of the gpu. i think when i'm playing something that pushes the system, eg The witcher 3, heat transfers from the gpu backplate, and gets absorbed by the cpu cooler's heatsink

Yep I've watched that video before I bought mine, my case it made better for air going out the top and not in through the top search aerocool x predator evil. The biggest one. It depends on the case and the airflow of the case, mine is good airflow and my fan setup compliments the air pushing up onto the radiator more.
Answering your question, I think it would depend on where your case is and how you are having yeh h100i set up. If there is no space at the back of your case, against a wall and very little space I wouldn't have exhaust going on the back, mine is a good 10cm from my wall so mine is fine. Also I would have both side fans I taking just because it looks better and it has better airflow and keeps the air cooler. Would reccomend trying to get some voltage adapters so you have exhaust on full, and intakes on lower voltage. But it won't affect the temps too much, so it is how you want it too look and be accessible from there. Just try it one way and see if your temps are making you happy.
My temps idle were 19c with all fans full, so I used the adapters that came with my fans and it's now ideal at 22c so I can do what I want with my temps as good as they are.
Also if you buy a fan adapter I think it's 3 pin and 4 pin fans that support fan controll but I may be wrong, I know it is like that for the h100i corsair link.mi would just google and make sure if you think about getting adapter
Feel free to ask any more questions anyway.

I've got a low noise adapter with each of my noctua fans. I'll be using these fans to cool the radiator when I install it. My pc sits about 20 to 30cms from the wall, so there is plenty of room for the exhaust fan. I may just stick to using Thermal Radar 2, as you can set some good fan curves with the software
