Would this improve Air Flow.

Hello guys
I thinking Adding a Corsair H100i to Replace my H80, I have 3x Corsair SP in the Front and 2x Apache Blacks up top and the H80 is also intake.

Now
Say I was to put the H100i in the top two fan mounts on the front as Intake, and another spare Apache Black out take on the back, you think this would help air flow? Do you think the H80 over hanging the GPU's is blocking Air flow out the top case?

Is this worth £100 change? "sadly I was given a H100i but its broke" so its a cost upgrade I not sure is worth it?

Thank and hope you understand haa

I don't think it's worth it. The cooling performance between the H80 and the H100i is like 1-3c. With the card setup you have, you want to have the top exhausting out as much as you can, so the air from the graphics cards goes out of the case ASAP. If you put the top to blow in, and the only exhaust is the rear, you will fill your case with hot air pockets that cannot escape.

Turn the H80 into exhaust, keep the front as intake, and put the top as exhaust. Run the top fans as high as you can with the noise you tolerate.

DIY a fan on the bottom of the case to blow upwards, even if you don't have an intake for it. It will force the air from the GPU's to the upwards of the case.

Thanks for your reply.
The two top fans will stay out take, what I mean by adding in a H100i it will be mounted on the front of the case as intake and I will then put another Apache as out take on the back.
Still not worth it?

You will get better results having it blowing out. I have 120.5 of rads in one of my builds and even if only the CPU is under load, they are better off ALL blowing out. I am willing to bet that the h100i wont be as cool as my rads, so you will see a better performance gap.

Why do you want them blowing in?

Thinking because I can then have the better Air flow of Apache Blacks 140's moving air out the case on top and back faster?
 
The fans 'pull/push' air independently from each other. If your case was air tight, you would see more air flow from the top but because it isn't, so it wont make a difference i am afraid.

If i were you i would mount the h100i wherever it looked best and have the fans pushing outward.

Forget about convection currents too, not worth thinking about as the effects are negligible. So many people plan their route so carefully thinking warm air will rise and push through the top fans easier but in reality, if the power of convection currents were powerful enough to make a significant difference, we would never have to run pumps in water loops to keep the water moving round.

TBH the best way would be to either keep teh h80 or mount the h100i on the roof. Putting the h100i in the front will lower GPU air flow and in SLI/Xfire, air flow for GPU's would be my top priority.

+1 I've had a few comments from a few on another forum due to my rad/fan set up in my Enthoo Primo. I've got my top, bottom rad as intake, as well as my 2 front fans, then the single rear fan as exhaust. And my temps are lower than the norm of all fans as intake, and the roof as exhaust. ( It was this way first )

My way of thinking was the best positive pressure, plus with having the bottom rad as intake and the roof as exhaust, the roof rad would be sucking through the warm air from the bottom rad, and gpu heat. Also the norm of thinking warm air rises yes is true, but how much of a height difference is there between a desk top and the top of your case, to cause a problem ?
 
In my 540 I have my H70 pulling in at the front. Seems to cope fine on temps. 38120mm (including the h70) pulling in at the front, 2*140mm exhausting at the top, and 1* 140mm exhausting at the back. GPU temps are down by 5ºC compared to having the top fans pushing air in (tried out of curiosity)

Not a bad idea that, I could try putting the H80 on the top fan slot out of the 3 120mm fronts. That then would allow me to put my 140mm on the back "outtake"
