Thats how I setup my corsair fans on top of my case, I pump the warm air OUT of the case ....thru the radiator
Also have two fans on the back side of the case blowing out ... all my other fans blow IN I have 8 fans total All 140's except for one 120.

Nice! Mike .. good to have physics in practice!

This is from Corsair's website:

Let me tell you, it was an adventure getting the fans between the radiator and the case, I basically had to flip the case upside down, place the fans in place so the holes lined up, then carefully placed the radiator "on top" of the fans. Then tip the case just slightly enough to put in a couple screws through each fan hand tight into the radiator. Flip every over right side up and then insert the remaining screws and tighten them all down. This is in a Corsiar Obsidian 450d case.

I`ve done that on my Corsair C70 case, and yes it is very difficult to do it by yourself. I have since switched strictly to pushing. You get the fans on so much easier, then you just line up the radiator holes to the top of the case holes, or wherever you put it.

When I install my 9900X I may have to move my H115i to the front of the case and do a pull, because the Zotac is making so much heat during gaming.

Or just put my 1080 Ti`s back in

I'm not real impressed with my setup currently. The fans are pretty noisy when they spin up with heavy CPU load. I think I'm going to move them to under the radiator.

Don`t set the fans to PWM and they won`t ramp up and down, you can set them to balanced during heavy CPU usage, there won`t be much of a temperature difference. Remember, it`s all about room temp.

Nice to see you`ve finally filled in your specs

Depending on board you may not need to do that. On both my Gigabyte Z270 and Z390 all fan headers are 4-pin and the boards will auto detect PWM or voltage fans. And each header can be configured individually to use PWM, Voltage or Auto, and allows you to create a custom fan curves for each header. In addition you can link headers to zones - CPU temp or case temp readings. Example my rear fan kept ramping up and down until I took it off the CPU temp reading and assigned it to system reading. Now the fan stays at it's set curved value until the case temps rise. This is all BIOS (UEFI) controlled. There's also Gigabyte's Smart Fan software, but I prefer the BIOS settings since I set and forget.

Anyway you might check your owners manual to see how Asus works.

Exactly. whichever fan header you plug the Corsair into, you do not want it set to PWM (I use the Bios and Disable it)

Nice system Drew

I doesn't make a difference (just tested it) for tach readings. Remember the wire going to the CPU header is a single wire strictly for tach reading. The tach readings come from pin# 3 (sensor) and won't change whether voltage or PWM.

Also the pump gets it's power from the SATA cable which is why you can only control pump settings via USB through Corsair's Link or iCUE software. Also how you can control fans when connected to the pump.

Well I'm really impressed with my little Asus 120 - I can't even get Prime 95 past 65 degC on my R5 and it's whisper quiet even at 2000 revs and this does not have the Noctua fans of the topline range - the only way I can check full power and hear it is if I manually select it - then it runs at over 2500 rpm

I have 4 PC's but only one running AIO which is a CM Masterliquid lite 120 installed in a ThermalTake versa H15 case and I have it attached to the front of the case with it exhausting out the front of the case.
