Hey guys!
I'm looking at the Corsair H100x 240mm and I've overclocked my CPU to 5.1Ghz. I need some advice on airflow setups for overclocking. Also, I've upgraded my GPU, so it runs hotter than usual—keep that in mind.
First example:
***I'm not sure where to install the H100x (please suggest a good spot on top of the case)***

Be aware - heat moves upward. Therefore, the proper setup should be this way.

Be aware - warm air ascends. Therefore, the correct placement should be here: so where should I position the H100x 240mm at the front on top?

daniulianov :
where exactly should I install the H100x 240mm on the front, at the top? Either option works. Just keep in mind the airflow direction.

This product involves placing a back fan and a top fan near one another, which may lead to a struggle for airflow.

simple setup where the radiator is at the top and air is being expelled, it makes sense to push warm air back into the case. when you need more fans inside than escaping air, consider a case that can handle additional fans. for example, the Fractal Design R6 or S2 models are suitable options.

The Original Ralph explained his setup clearly. He mentioned that with a simple design, the radiator should be at the top while air is being expelled. Adding more fans inside would be unnecessary since the GPU also expels air. For a case with two rear fans, he emphasized needing a case with sufficient capacity and multiple fans.

He shared his configuration: top has the radiator with two 140mm fans pushing air out, rear has one 140mm fan pushing air in, front has two 140mm fans drawing air in, and the bottom has a 140mm fan drawing air in. This setup uses a Fractal R6 without the extended bay configuration, making the internal arrangement obvious. He also noted that placing the exhaust behind the radiator is logical because it's right below the PSU, which also expels air.

simple, radiator goes to the top - with air being exhausted - why would you want to blow warm air into the case?
and you want more fans blowing air into the case than air being exhausted, keep in mind you'll have a GPU exhausting air as well
if radiator has 2 fans, and one fan at the rear, you really need a case with capacity with more fans
Fractal Design R6 or S2
Got it, bit let me share my setup then:
Top: radiator, 2 x 140mm fans exhausting air
Rear: 140mm fan exhausting air
Front: 2 x 140mm fans intake
Botton: 140mm fan intake
This is a Fractal R6 without the extende bays setup, so its pretty clear inside the case.
The reason I did the rear as exhaust is because right bellow it its the PSU, and it also exhausts air.
that's the very case i;m going to order in Jan or Feb - looking for a sale price
but you're still going to have a GPU exhausting air - i;m thinking to open the PSU shroud (ie, cutting that perforated grating open to allow easier airflow into the case
I;m also thinking about possibly boring a hole in the left side case cover to mount another fan or two blowing straight at the motherboard's VRM and cooler
the coolermaster HAF 932 http://www.coolermaster.com/case/full-tower/haf-932/
Not the prettiest case but it sure does get the job done, plus i need all those 3.5" bay slots

What I did instead was purchase (during black friday) a 1600W Gold PSU for my system that will only consule 455W at maximum. This way not even 50% of the PSU is used, that means less heat is generated. My current PSU the fan runs at minimum speeds.
Plus its future proof if I ever want to add a SLI configuration or any other devices that consumes energy.
I know it might see like a waste of money, but I got an EVGA G2 1600W for 160$ only! That was a great deal
