Is a fan controller needed?

[Reloadron]

Someone please correct me if I have some of this wrong but I see a small problem in the master plan of things.

2 Fans for the CPU cooler will work.
1 Exhaust fan for the case rear will work.
1 Intake fan for the front of the case. I see a small problem.

The fans chosen should work fine blowing down into the CPU Cooler:
Cooler Master GeminII CPU Cooler Review - the Cooler

The fan of choice here is the Arctic 12 (120 mm Fan). This fan is pretty much designed to function as an exhaust fan isn't it?

The fan only allows mounting on a single side unless some standoff system is devised. Thus, if the fan were mounted on the front of a case in a normal fashion, it would exhaust and not bring air into the case? Unless I am missing something along the way here.

As to fan speed control there are some pretty nice controllers out there to be had. With the proposed setup I don't know as I would be too quick to worry about controlling fan speed on the CPU cooler. I would likely just let them run full speed and see how quiet things were. Then if noise was excessive I would pursue a speed control.

Looking at the case design of the selected case, I would definately want a front fan simply because it would aid in keeping the HDDs cool. Assuming I am looking at the picture correctly? I am just big on having forced airflow over the HDDs when possible.

The only small downside I see to using a fan speed controller is that unless it automatically adjust for temperature, it is not quite a set it and forget it affair. The user needs to manually compensate. Controllers that do compensate are sweet as no user intervention is needed.

Anyway the only small quirk I see is that case front fan with the selected fans.

I would likely just use the adapters mentioned and just see how things sound. Then work from there.

those fans are being used for the CPU cooler, as they were recommended, and as they were used in the review of that cooler

Yes, and I linked to the review. I think they were great fans for the CPU cooler. I was just wondering about the use of the front case fan? Aren't those fans designed primarily as exhaust for case applications?

yeah, exactly right....they can only be used as exhaust fans because of their design.

Actually with some minor mods and some fun, these fans can be used anywhere. I just wish I had a couple to show off my ideas. Until then I'll just have to keep on using what I've got.

Fluid Dynamic Bearing fans are the absolute best around.....The performance to noise ratio is phenomenal.

Arctic Cooling offers a variety of these fans for every need.......
The Arctic 12025PWM is the exact same fan with a full fan body

Speaking of Fan Contollers, does anyone know of a controller that will work on Molex connections? I want to put the 4 fans for the Nine Hundred on a single controller for ease of adjustment.

Its tough because most fan controllers have a limit on load.....which is why these fan controllers typically have 4 separate channels to work with.
The fan controller I linked has one 4 pin molex input, and four individual 3 and 4 pin molex connectors to run to the different fans

The unit I linked to is going to be used in my 900. I can't wait to get started on it, Bailey.

I thought I would mention this fan controller...

It's called the T-balancer BigNg. I discovered it a few months ago, while researching about watercooling. It seems to be very popular in the w/c community because you can plug just about anything into it including pumps.
