H100i cooling setup in 350D Case

[AthlonXP]

Just checking in to see if I can get some suggestions on fan placements for the H100i in the Corsair 350D case. Unfortunately there is not enough room to do a push/pull setup so I was wondering where would be the base placement for the 2x 120mm fans. Right now I have it setup with the 2 fans pushing the air up with the radiator attached to the top of the case.

You could do a push pull if you placed the top two fans outside the case.

I was considering that but I really want a simplistic look and not a setup with fans sticking out from it.

The best cooling performance you will get by placing the fans as intake not matter if are push or pull it will be the same that has been tested for ages with the same results.. Thats with the best cooling performance but only for your CPU. The rest of your system will receive the warm air disipared by the radiator and overall you will get higher temps, so even reverting all the fans on the case you will have turbulent airflow. The best option its always put the fans as pull exhausting the warm air out the case, and you will not have to reverse any fan, the vast majority of cases are designed for a front to rear and bottom to top airflow, hot air molecules are less dense than cold so they will rise, thats why its better to follow the physics and nature laws. Not matter if fans are push or pull, They should be as exhaust. But i recommend as pull always, by the simply fact it will be a ton of times better to clean, and you have to clean less time in the same time. I'd tested lot of times with my h100i pull or push in exhaust or intake. Intake you can gain 1-3 degrees C(depending on your case and fans setup) better cooling performance but a overall increase of temperatures from 5 to 8 degrees.. (Specially on RAM).. So it realy depend on what you want, in my C70 case i have the upper side panel fan as intake so they radiator its constantly receiving cold air and the lower side panel fan as exhaust so the heat generated by my GPU its rapidly out so it can keep a fresh enviroment in the top, so the temps aren't a lot of diference. But the diference on dust its day - night. With h100i fans setup as intake you have to clean your radiator and the case inside weekly (at most, depending on how dusty if the area arround the case).. With fans as pull exhaust you receive the same level of dust in more than a month on the case and like 3 months on the radiator i don't now exactly because i clean my case every month. But thats my recommendation.

Honestly there is no definitive answer. Over the years I've seen just as many people claim pushing works better. I think it all boils down to the fans and the radiator.

But either way op unless you put them on top, you likely won't get push pull.

theres no law in the world that can corroborate that push fans its better than pull. as you said all its resumed into what fans with what radiator. not the same a super high FPI radiator like h100i with low RPM high airflow than low RPM with high Static Pressure. High airflow maybe perform better as push, but overall will perform far way Worse than Static pressure, in this scenario with a h100i stock fans tested with sock fans, with SP120 Quiet, SP120Performance and Noctua NF-F12. both pull and push show the same temperature cooling.. not only me, i remember some video of linus talking about that...

OP, sounds like you already have it in the best placement. You probably wont see much, if any, difference in the temperatures if you were to "migrate" to pull, rather than push. Go with whatever fits your aesthetics in the case, be it fans on top or bottom of the Radiator.
