The positive pressure isn't just input RPM vs output RPM. You'll have to have a rough idea of how much air the fans will move. You want more pressure pushing into the case than pulling out. So, try and arrange the fans so that most of them are pushing air into the case. The front 200mm is 1, if you add one to the optical bays that's 2. If you're going to make the cpu cooler intake, that's effectively 3 intakes. You could have one large 200mm exhaust. That would give you less output than input for positive pressure. You may prefer two 120mm exhaust fans up top. Since you'll be using a fan controller you can go either way. The 120s might allow for better control, but the 200 would be fairly quiet.

As for the SilverStone case, it looks pretty nice. That style is not my personal cup of tea, but I can see how some people would really go for it. It's pretty different. I prefer the more standard design myself.



From the first page: "replaced them with one Noctua NF-S12B FLX at the back for exhaust and two of the same model at the top, as intake fans".

He has turned the case into positive pressure by converting the top into intake, but keeping the rear as exhaust. We are discussing something similar right now by regulating the exhaust flow out the top and converting the rear into an intake for a rad (H70).

so all the air exits out through a single rear exhaust fan that has been upgraded to the noctua? sorry for the confusion

ty for the clarification though

This actually gives me an idea. (excuse me if you get a burning smell) I would like to try an experiment whereby a separate fan controller was used so you can vary each fan individually. IF all the fans you are controlling have a lower power draw than what the built-in stock fan controller can handle, you could plug the the aftermarket controller into the stock controller and use the big knob on the top as a "master control" for all the fans. That way you could keep your positive pressure all the time while varying the air flow through the case. This would likely work best on a nice simple manual fan controller like this one:

It looks like it wouldn't use much power over what the fans would draw. If you're only using 3 or 4 fairly low power fans I think this would work great. However, if your fans pull a lot of juice this might kill the stock fan controller.

Anyways, sorry for that. I would pick an after market fan controller if I was you and use it to control the pressure in the case. Don't forget that a dust filter will cut down on your air flow.

I am using my H70 as exhaust for two reasons. 1. It does not pull outside dust in through the H70 and 2. I have video cards that exhaust out the back so I'm not pulling hot video card exhaust through my H70.

The other two fans in the rear are also exhaust. All of them are connected to an aftermarket fan controller except the H70 fans, which are connected to the CPU header. (I used PWM fans for my H70 and a PWM fan splitter).

Without a fan controller, the only way to make sure you have positive pressure is to try and calculate the air pressures based on the fan specs. This would not be entirely accurate due to the dust filters, mesh and grills. With a fan controller you can experiment on which RPMs for which fans achieve your desired result.



Hey, that's great to hear. Glad you got that figured out. That's what I went for with the PWM splitter and fans for my H70. I absolutely love the automatic control.



Looks good. I love the job you did on the switch.

I love having these guys a few blocks from me.

Here's the fan testing thread again for everyone asking about 120mm fans:

CeaserNYC, after I eat I'm going to try your fan mounting idea (now that my basement is dry). I will report my findings later tongiht

Looking at your pics, I saw that you mount 2 pcs of 120mm fan on the front as a replacement to stock 200mm fan.

1. How do you mount it? Use a velcro or drill new hole?
2. What is the brand of the fan? Is it better compare to GT AP-15? 'cos I had 2 of them as spare.

PS: Mergatroid share his experienced about 2 page before that 25mm thick fan will not mount in the front while the HDD cage mount behind it, so he did a little mod on the HDD cage.

Thx..

The button on the pump unit is a bit different from a fan controller though. It sets a profile, and I figured that most people would find the profile they liked and stick with it. The profiles aren't a static fan speed like a fan controller would set, they're a range of fan speeds based on internal coolant temps.

Low - 900 RPM to 1300 RPM
Mid - 1300 RPM to 2000 RPM
High - 1600 RPM to 2600 RPM

If you want, you can use a standard aftermarket fan controller (like those built into some of our cases) and no harm, no foul. But if you think the idea was stupid, I'll take the blame.

Why the hell would I want to open my case every time I wanted to change the fan speed? Really stupid move on Corsair's part. So now I need to find a new cooler to buy.

Second do you think Corsair will ever make it's own line of case fans? I ask because I would love to see really good purple LED fans that have higher RPM and CFM ratings, that will also last.

of the CPU. I have placed a 120mm fan in the CPU backplate access hole blowing air onto the back of the board. At his suggestion, just for the test, I let the mess of cables hold the fan up while I closed the hatch.
