Do AiO'S NEED Fans?

[Aytex]

Ones like the h100i looks really builky in ITX Cases so I was just wondering on how much it will effect the cooling performance

Where is all the heat that goes into the rad going to go?

USing the Case's Fans and not the ones on the RAD, i was wondering if just using the case's airflow has enough pressure to cool the rad's

You NEED them or the rad can't cool itself. The fans move the heat from the rad off the rad so I can heat up from the hot liquid. The fans are pretty much necessary  although they do make low profile RADS and low profile fans

Depends on the components and the body.

What are some low profile 240mm's? for around $100

Actually no, this is a true story where my fan controller went bust so for 1 whole months, my 3570k ran with no fans on my h100i and the temps stayed under 75c gaming and 85c with p95 running...obviously with 2 OEM sp120 at lowest speeds, with p95 it only goes up to 60c and with gaming up to 55c...but yeah...you don't need fans...(I guess I did have my 2 h75 fans pulling air out of my case while my other 4 fans idled...due to no power...but those were also at 5 volts so...not much air indeed...)

at that point you might as well not buy a AiO, hmm, alright thanks!

Actually, it depends on what chip you are running, I was running 65C With a 4690K At stock on a H110 With no fans.

Don't know any of the top of my head sorry, I would use PCPartPicker.com or make a new post about that in Liquid cooling section like this one is

You NEED a fan in an AIO to cool the water in the radiator.

 

Since its an AIO, it should come with a fan so youll be goooood!

You don't it will dissipate a small amount anyway, the thing that matters is the water temp and rad size and he has fans directed at it

If you have good intake fans that can generate positive pressure inside the chassis and that pressure then causes air to flow through the radiator you could get by without radiator fans.

 

The problem is that the air will tend to flow out the path(s) of least resistance - open vents, gaps, etc,  And not flow through the radiator.

[Dschijn]

Exactly! The case would have to be air tight and the fans would have to build up enough pressure to overcome the resistance of the radiator to provide enough airflow for cooling.
