Cooling experiment

post #1 of 7
Thread Starter 
Hey guys, I ordered a coolmaster 212 the other day, and it should get here on the 5'th.

Now this is a two part question so hear me out

1: Can you put ANY 120mm fan onto the 212+? I have a 190cfm Delta fan That is just begging to cool a cpu!

2: Can you get a type of fan controller (or something of the sorts) that EITHER
A: can control a Delta fan (3A) or
B: Will turn a relay switch on when the temps exceed a specified number?
C: Does both?

Thanks guys!

- Kieron

1.Yes
2.Yes
A. Yes
B. with some soldering Yes
C. definitely yes.


For 1. You might need to make some clips to fit the thicker 38mm fans yourself. It's easy with some wire from the hardware store and some pliers.

2.
A. Look for a controller rated at 40w or more. The Rheobus Extreme or the Lamptron Fc-2 come to mind.
B. It is a decently easy job to split the 4 pin connector two two connectors. Have the + and ground on a molex, the sensor wire and pwm plug on a 4 pin connector, that you plug into your motherboard's cpu_fan header. That way you can use the motherboards temperature based pwm control without killing your mainboard due to the current the fan draws.

C. There are a few posts here and on other forums where people have built their own PWM control circuits, those would be an option for point C. but are a lot more work.

Awesome, thanks for that.

Do 40w+ Automatic fan controllers exist? (under the £30 bracket anyway)

Im not aware of any, sorry. All i could think of is building your own programmed controller, for example using an arduino board and using that for a PWM circuit to control the fan.

I was thinking of building one my self, but its been years since I did any proper circuitry. The only programming I did was with a Pic (was quite fun too!).

Well Thanks for your help, Be sure to gimme a PM if you do find an Automatic fan controller that will support a 3A fan.

on a side note, I bought a rather nice looking one not too long ago from my local pc shop (they didn't want it anymore and said, if it don't work We'll give you your money back). So I ran home hoping it would solve all my problems, plugged that sucker in then promptly made a small bang and poured smoke.

Bugger.

Also, do you know anywhere were I could buy some molex's?
Preferably with a bit of cable on the end already.

I have a bad tendency of clipping them and loosing the molex. my Delta fan is a Frankenstein of a thing now, and if I did buy that controller, I wouldn't be able to connect it

Most automatic controllers allow for less then 10W on each channel.
You Delta with 3A on 12V draws 36W running, with a spike of approximately 40-45W when being switched on.

No wonder it went *poof*

The Lamptron FC-2 uses 3 pin fan connectors, so make sure to connect only +12v and ground, leave the other two disconnected. You will need a 3pin and some crimp-connectors.

Here is a UK based retailer that is recommended in the following thread: http://www.overclock.net/case-mods-g...-services.html

Link to the shop, specifically the plugs:
