Default Super Flower SF-609F Fan Controller

Lazyman is on a roll, he takes a look at a multi-colour fancontroller from SF


Quote:
The question I raised to myself was; why do I need one? It would be like after jacking up my engine output only to put a fuel limiter so that it won’t go as fast. Well, not exactly, the rheobus acts as a throttle cable or linkage so that one could dial up or down the speed according to the traffic pattern. Now, I get it. Okay, I want one.

nice review, I like it.

it seems a great rheobus, especially for it's small price

I still remember the €20 rheobus from Noise Isolator I once bought. one knob didn't turn very well. they don't lower the 12v rail like most rheobusses do, but used some trick to alter the negative voltage between 0v (fan 12v) and 5v (fan 7v). also, the fans vibrated heavily because of the flaky voltage adjustment causing MORE noise instead of LESS.

No vibration on this one. I have the second unit still installed in the W/C unit; with dial turn all the down the 92mm fan is turning at a lazy 1800 rpm; up to 3200 at full throttle.

Actually the wrong "bulb" type sensor is more ideal for P4 heatsink; I installed it like an AMD OE sensor - having it "semi" sticking upward enough to "touch" the heatsink base.

As for pricing ...... I HAVE to pay twice .....

Still learning the system here.
TeuS, I sure will add some tech numbers in. In fact, with two I have, I should compare both in lows and highs.
"They" get away with "murder" in anything related to power switching without UL requirements.

What I'm trying to say; good example with Power Supplies. I refuse to review with a single unit.

I'm golfing tomorrow; will get the numbers as soon as I can.

By the way, this unit is pretty well built. I have 10 years in medical (micro) electronics and 7 years in automotive electrical. This is NOT the one that fools with negative voltage. But, I will get you the numbers.
My concern was on heat built up with the regulators which turned out not the case.

Okay, here is the voltage reading; using Sears Brand Autoranging Multimeter Model 82028.

Readings are taken from the Fan Controller 3-pin connectors.

All four fan controls show within +- 0.02 Volt delta

Lowest setting 6.83 Volt
Highest setting 12.45 Volt

The highest setting is the same as reading from 4-pin molex from PSU. However, MBM shows 12.4 Volt. The difference could be from motherboard power supply circuit.

Lowest setting at 6.8X volt on 80mm fan = 1770 RPM
Lowest setting at 6.8X volt on 92mm fan = 1860 RPM
No vibration none unusual noise ... only lower fan noise.

Highest setting 12.4X volt 80mm fan = 3060 RPM
Highest setting 12.4X volt 92mm fan = 3150 RPM
No vibration none unusual noise .... only higher fan noise.

I also tested the continuity from low to high; voltage increases steadily. Rotation of all 8 knobs from the two units has smooth consistent feel, i.e. I could set it to 7.5 volt if I wanted or 9.4 or however within the range. I'd say this is pretty darn good.
