1 x 200mm or 2 x 140mm

Hi

I currently have a Cooler Master MegaFlow 200 Silent Fan in the top of my Cooler Master Stormtrooper case and because I've just upgraded some components I've been considering changing the fan. Is it better to stay with what I have or change to 2 x Noctua NF-A14 PWM

My first and only question: Does it work? If yes, then why waste money and change?.

Is this your best attempt at irony?

I'm personally not a fan (lol) of 200mm fans, and Noctua are the kings, I'd go 2 x 140mm

Thanks for the help guys, I went for the 2 x 140mm Noctua.

Would it impact on the speed of my Grahics card if I moved it to the 2nd PCiE x 16 slot as the card seems to generate some heat directly below the CPU. I feel that if it were in the lower sloty there would be a better air flow over the card.

You can try. It may help, but hot air moving around D14 is better than colder air not moving. You can also try speeding up case fans. Will it improve performance of the card?I doubt it. Few degrees you can drop the temp down wouldn't impact performance drastically.

Thanks for your response, I'm more concerened about the heat coming off the card and warming the CPU. If the card was lower then it's more likely to blow the heat off it and through the back, I just need to know that if I use a different PCIE slot will it change the performance of the card or should it always be in PCIE slot 1

Ok now the Noctua NF-A20 PWM is out, i'll ask the questions again, LOL^_^

I have already bought Noctua 2 x 140mm NF-A14 PWM and according to the specs it moves 140 cubed meters per minute at full bollocks at 1500 RPM.

The NF-A20 PWM moves 147 pm at 800 RPM.

Is it wise to assume that 2 x 140mm fans will move approx 140 cubed meters at approx 800 RPM.

Im aware that if temps get higher that having the ability for the 140mm fans can double the movement of air. I think I'm answering my own question here. It would appear that the 2 140mm fans would be better at keeping the case cooler than one 200m because I have more overhead to play with.

Can anyone confirm this?
