Both of the jacks where 3k RPM Ultra Kazes connect are messed up.
At first everything worked as it should but now they can either be 100% or off!


Im going to RMA it but kind of sad that the KAZE MASTER can't handle the Ultra KAZE fans...

Anyone know of a strong fan controller?


UPDATE:

Ok the Rheobus came in the mail today. Works great so far. 2 gripes: comes with only 2 real 3 pin extensions. The others are molex to 3 pin and Y type to connect it to the mobo as well as the fan controller (Couldn't get this to work correctly).
Another one is that the lights can't be tuned down. As the RPM changes so does the light but it starts off bright enough!

The build quality is definitely better than the Scythe Kaze Master. It has big heatsinks.

thanks for the suggestion.
Hilariously enough I own one of those but as you said they are pretty simple. I liked the look of the Scythe. But I'd rather use something that will actually work!
Is there a 5.25 bay version?

Odds are good that your replacement will be fine. But the Sunbeam Rheobus has the same specs as the Vantec and costs about half of what Frozen asks for the Vantec. The Sunbeam is a 5" bay unit. Or the Sunbeam Chromatic Windmill can handle up to one Ultra Kaze 3000 per channel. Both available here: http://www.jab-tech.com/Fan-Speed-Control-c-42.html .

I didn't build this because I'm one of those "live off the land" types who has to do everything for themselves:

DIY binary fan controller

Rather, I surely wasted more time looking for a design that wasn't junk or overly ornate that I could buy, than I spent making this.

I have on order from Mouser some SP3T toggle switches and 3A diodes, so my next prototype can control two fan circuits of 3A each using base 3 and two pairs of toggles. (I want my TRUE fans on a separate circuit. Base 3, not binary, was nearly Von Neumann's first choice for a computer design.)

Active circuits run hot and usually top out below 12V. Passive rheostats don't get rid of heat as easily as a series of diodes. Toggles are simpler and more reliable than rotary switches. So this was the simplest, cleanest design I can imagine for my current loads. I detested the jumble of cables that came with most controllers I could buy. Like I said, I would have just bought this if I could. But if you can't buy it, build it.

I bought this because of the led temp readings and the damn thing near caught fire w/ one 3,000 rpm 38mm Kaze. POS, don't buy this! The sunbeam zepper mentioned looks good but after the one that I bought I'd call jabtech first to see if they will back it up before buying.

I also have a Cooler Master Aerogate 3 that works fine. But the heaviest fan I've run on it is the Sanyo 1011 at 0.52 Amp. The AG3 has been discontinued for a long time but you can still occasionally find a new or used one out there. Then there is the Silverstone Eudemon (SST-FP52S or B), but it doesn't have as many channels - kind of pricey too unless you buy a TJ05 case along with it (doesn't add much to the price of the case - the ones with the Eudemon have X in the suffix - SX is silver with, BX is black with)...

The two versions of the Sunbeam Rheobus are actually one of the few rheostats I've seen that has heatsinks for each channel. I also have a different fan controller without the heatsinks, and I've damned near burned myself accidentally touching the heatsink-less transistors after working on the rig immediately after powering it down.

Ok I placed the slower fans on the busted controls. They're running full speed or off too but full speed is 1000rpm.
Just a while ago one of other control got messed up too!
Wow...

I'll give another +1 for the Sunbeam Rheobus controllers. I've got one of the "original" versions and it is great, albeit simple. Has 3 Scythe S-Flex "F" fans on one channel and hasn't given a problem for almost a year of continuous use with that.

Remember, there are two versions.....the original that handles 20W/channel and the upgraded version that handles 30W/channel. Heard the new version's LEDs are a lot easier on the eyes, too. Probably will be going in mine to replace the old one I've got simply for the reduced LED brightness.

the sunbeams are nice.

However i really dont think i will ever find something to replace the kaze master.

The reason why i love it so much is the VFD and also th 4 temp probe prongs.

I cant live without my monitors, and 4 is exactly how many i needed. :\


I seriously recomend an RMA. And try again with a new one. As i said ive been using mine for quite a while with ultra kaze's and havent had any problems.

Linear fan controllers' transistors need heat sinks while PWM chips generally don't at the power levels of most fans. The former is a resistive control while the latter are switches with less than a volt of wasted power.

Yup, the Sunbeam products generally come with little in the way of extras. My Aerogate came with a fan extension for each channel, but then it retailed for over twice what the Rheobus did.

Single wire rpm monitor plug to mobo, looking at this yours have the ground as well so it is the female plug w/o the red wire to the mobo.
3 wire female to control,
3 wire male to fan plug

Many times to dim lights I've painted the recessed parts of the knobs to block some of the light.
