Corsair Carbide Series 200R question

[CDC Mail Guy]

Quick and simple question

This case ----> http://www.newegg.com/Product/Produc...82E16811139018 has two places on top for exhaust fans.

If I use both of them (120mm), should I still use a rear fan for exhaust as well?

You'll get more effective exhaust of hot air with a fan in the rear slot than the forward top slot, so yes. You should always use the rear slot in a typical ATX case with standard motherboard orientation.

However, I don't recommend a fan in the forward top slot at all, assuming that the components you're putting into the 200R are the ones in your signature. A single graphics card setup just doesn't need so much exhaust airflow, especially considering that the 5850 is by no means a power hungry card.

I have tested various cooling setups in a Fractal Design R3, and having a fan in the forward top slot (in addition to the other two exhausts) had no effect on temperatures. In fact, the difference that I measured was something like one degree higher GPU temperature. Although that's pretty much within the margin of error, you could theoretically get worse temperatures when your intake airflow is diverted to the top fan before it even reaches the graphics card.

Thank you for the reply, lehtv, and I will remove the top front fan and put it into the rear of the case. The components are not the ones in my signature, but since I upgraded my CPU and memory, I bought a cheap mobo and case and am doing another build with my old cpu and ram.

The video is onboard, so there will be no graphics card. Also...I am just using the stock cooler, as this will not be overclocked.

I think the top looks funky with no fans at all, and I regret the purchase of this case, but the price was right. Also, the front intake fan...I am not sure what good it will do...if any. I already removed the hard drive cage, and will figure out where to mount the single ssd later on

Thank you again for the reply.

To be honest, for a system like that with just the stock CPU fan and integrated graphics... I'd rather have two intake fans and one exhaust, than the other way around. That way, you'll have slight positive pressure inside the case, which means (theoretically) that all intake air is filtered, keeping the case dust-free. If you kept two exhaust fans and only one intake, negative pressure would cause air to get in through openings other than the dust-filtered front intake area.

Uck... (Yes, I know that's not a word)

That would mean that the top of the case would be fan free...therefore making it even uglier Nothing (dust/dirt wise will fall through the top vent holes?

However, I will do as you suggest and put another fan in the front of the case as intake. I did, after all, come here looking for help

I will check back later for reply. I have to leave my work area to another with no internet

Obviously gravity would cause dust to fall through the open top when the PC is off, but when it's on, almost all of the air that gets into the case should be via the front fans.

You can also block the top with something if you like, but I don't think it's really necessary unless you want to avoid spilling drinks or whatever else into the case (in which case fans wouldn't help either).

Done, and even with good quality filters covering the intake fans, it is silent and cool air is actually blowing out the back. Thank you. Now...off to find a good inexpensive HSF to replace the jet engine of the stock AMD fan... Grrrr....

I still don't like the look of the top of the case with nothing there, but as I intend to sell it, whoever buys it will have to deal with it. Or put a vase of FAKE flowers or a plant to cover it...whatever...

What's your budget?

You can usually find the CM EVO for ~$30, here it is for $30 at amazon,

Already got, thank you though for link. Of course though, I went through Newegg...ordered yesterday and it's already on my doorstep awaiting my arrival home from work.
