Tuniq Tower 120 + Fan Controller

[Cheex]

The Tuniq Tower 120 fan is supposed to run at ~1000RPM to ~2000RPM.
Those are the speeds I usually get from it when I used the expansion slot controller that comes with the tower.

Since I've connected it to the Zalman MFC1-Plus that I bought...I've been getting a range from minimum to maximum of ~150RPM to ~1800RPM.

What gives?

I turned the fan on minimum at first, which I thought would have put it to ~1000RPM, the I noticed my overclocked CPU temperature rise above where it normally would be, even when crunching.

I investigated and found that the problem was this low fan RPM.

I want quiet but I don't want to have to be checking my temps every time I want to turn my fan down.

What gives?

looks like the zalman has a greater range of speed that it can command the fan at. it's allowing you to run as low as 150rpm. I would just set it somewhere near the middle where your comfortable with the noise/performance ratio. Just make sure e6300 stays cool.

The thing is, I don't have a problem doing that, as a matter of fact, I've already done that. But...

I was just wondering why it was doing so. I found it kind of strange.

where r u getting a the fan RPM readings from? pretty sure 150rpm isn't possible on any 120mm fans

CPUID's Hardware Monitor.

I was also thinking about replacing the fan that comes with the Tuniq (I wanted LEDs) but then again...

When the fan is 1000 RPM, it is 42.98 CFM.
When the fan is 2000 RPM, it is 82.41 CFM.

I think those are the official numbers.



Also: How good is Hardware Monitor at monitoring your temperatures?

The fan controller is just a simple potentiometer. The Zalman just seems to have a wider range of voltages, and also a little higher voltage loss than the Tuniq controller. It is a very simple device that you could easily create yourself if you are unhappy with the one you bought. I can give you some tips on building one if you feel the need.

Thanks a lot for the info and the offer but the Zalman works fine...:thumbsup:

It is just that I thought there was a built-in range that the fan circuitry would automatically determine and maybe relay to the controller for the minimum and maximum value...

I'm also familiar with the electronics because I did well at Physics in high school...

Thanks though...:beer:

No problem. Actually the Fan is a simple dumb DC motor, so it doesn't really do any computing. It just turns when you give it power.

Also, I didn't want to make it sound like I was saying you were stupid for not knowing this. I just have a lot of experience with DC motors and controllers from various projects, so I probably had a slightly better understanding as to how that all worked. (Plus I am an Electrical Engineer, so I may have more training in that area if you are not an EE.)

I think you had a better Highschool Physics class than I did. While I don't remember what they taught in High School, I am pretty sure I didn't learn about potentiometers until either my 100 level Circuit Theory class, or maybe the 100 level Physics class. I don't think I really understood anything about electronics before I went to College (Which made the early classes rather difficult for me).

I have built voltage controllers with Potentiometers for specific voltage ranges before, so if you ever decide that you want finer control over your fan, let me know and I can tell you what to get to build your own controller. (What you would want is to build a voltage divider circuit, with the potentiometer on the top half of the divider covering the effective range of the fan. While the resistance values in theory shouldn't matter (as long as they are high enough that you aren't pulling too much current) in practice, the higher resistance you use, the finer control you will get - plus it will help that the quality of the pot will be less important. edit: I also forgot to mention that the higher resistance that you use, the less voltage drop will occur because you are drawing less current.)

What kind of temps are you getting?
I'm curious...see my thread here as to why.
Also, I've tried different fans in my Tuniq...the stock (can get loud), a Yates-Loon D12SL-12 (I don't think it fared any better, but it was a little more quiet), & this fan which had a potentiometer/thermal sensor (one could use one or the other or perhaps both?). It was also a pretty blue...hehehe.

Is that Coolermaster fan any good? Does it live up to its specs?
