Hello guys,

Sorry to ask such a simple question. I am looking to build my first workstation over Christmas and am slightly confused which is the best airflow setup within a 650d case. I am getting the H100i and my current thoughts are:

Front Fan: 200mm Spectre Pro = INTAKE
Rear Fan: 120mm AF120 Performance Edition = EXHAUST
Top Fans: H100i with SP120 Quiet Editions = INTAKE

Would this be the best option? OR would it be better to have the H100i Pushing or Pulling air into the case? OR have the H100i as an intake by pushing or pulling? Really confused....

Cheers in advance! Any pictures of previous builds would be of much help!!

i would set the top fans for the H100i as exhaust otherwise you blow the hot air from the radiator directly to the GPU affecting its temperature.
all the other fans should be fine.

Do not use quiet edition fans on the h100i I did and it isn't wise :)  I would just get good static pressure cans on the h100i the performance edition fans SP120 are good as well as the Noctua NF-F12's. And use them as exhausts.

I disagree. The purpose of a radiator is to draw cooler air across a warm radiator in order to cool the liquid. Think of your car radiator - you wouldn't pull hot air from the engine compartment for cooling purposes would you?

Set the front fan as intake, set the H100 as intake and set the rear as exhaust. You want more intake than exhaust to maintain positive pressure in the case.

True but I was only stating for the radiator.

front push air in
top push air out
rear push air out
if there is a side fan push air in

Thanks mate that sounds like the best option, shall I have them as a push or pull? Or does it not matter? :)  do you know where I can get one from as everywhere seems out of stock at the moment... I'm in the UK and both overclockers, Amazon and Scan are out of stock!!

There appear to be some in stock at a couple of UK sellers. See list HERE.

I would set the cooler up with fans as pull (case top>fans>rad) to get the best shot at airflow.

As an aside, I'm not a big fan of AIO loops. I prefer air cooling (Hyper 212 EVO, Xigmatek GAIA, or in extreme cases Noctua) as the only part that can fail is the fan. Since the fan is monitored by the cpu fan header and required in order for the pc to run, a failure tends to shut off the system. With AIO loops, you have the fans, the pump and the chance of leaks. The KISS principle rules here for me.
