as i mentioned, i have no fans running off the H100 block. Also, with the two inline i believe its slightly higher than 10.5

min voltage I measured before i loose RPM signal from the H100 is around 7 volts (around 1200 RPM)

So i have plenty of leeway. Im sure if i was running the four fans off the H100 ( why would I when the MB supports PWM funtion) I would need to worry.

Also what about all the other members running there H100's using a fan controller....... Im sure im only one of many that are running it at around 1750-1800 RPM

I double check the Voltage output tomorrow morning. also link me to where Ram guy said this.

Also go back a few pages.. post 225. George states that they got to reproduce our solution by running it at 1800 rpm. Probably by limiting the voltage....

I/we really appreciate the fact that you're involved in this and helping us.

That said, what statistic/number do you look at? I've seen multiple....meaning more than 100 people say they've returned at least 2 units with the noise. That's equal to at least 200 units and I'm guessing based on ww's info and my personal forums searches, that there are way more than that. Your statement, along with information on multiple forums, would lead me to believe that the perceived return rate between H80's and H100's is extremely skewed.

I guess I'd really like to know what number is in the single digits based on the number of sales world wide? I happened to buy one H80 unit off of amazon and it had batch number 12019402. It had the chatter problem until I installed ww's diode fix I bought at radio shack.

Thanks! And that is a fact, the Molex connector isn't of particularly great quality, it seems that the pins and the housing are mismatched. One of the pins broke off in the H100 I had.

The fan controller part of the unit runs off 3,3V supplied by an LDO, so as far as you keep the input voltage above the LDO's minimum input voltage, the fan controller will work (RPM reporting as well). The specified minimum input voltage for this regulator is Vo + 1V, so it's 4,3V. Smoke1991 suggests the RPM signal drops at 7V, this might be due to the IC shutting down or the pump actually stopping, either way there's no point in going that low.
The pump will slow down because the reference voltage for a voltage divider that sets the RPM will change, but it's hard to notice any difference in cooling efficiency while it's running at 1700RPM as compared to 2100RPM. Slightly different solution than that voltage divider would allow the pump to maintain the RPM even when slightly undervolted.
The actual difference might be coming from the fans connected to the unit, which will have lower maximum speed when the voltage is lower, and it's probably the only downside of lowering the voltage supplied to the unit that I can see.
Therefore I do not see how one could damage the unit this way - by lowering the voltage, but keeping it reasonably high (above 10V).

is it normal that the radiator makes a lot of noise too?

radiators don`t make any sort of noise....the only noise (if you can call it so) you may hear is the water+air travelling in the loop but this occurs briefly when first starting the h100 for the first time

with the two diodes inline im getting 10.6 on my multimeter. So -1.4 total off.. Unfortunately I cant test using my the fan controller I mentioned earlier due to its interaction with my foot earlier this morning doh.gif One thing I can add, from looking at the now demolished Fan controller, There is a diode already attached that looks identical to the diodes we are using to get out voltage drops. I cant really read the full part # without cutting it off the board but it does begin with "N" and is a 100X series unit. I guess most if not all fan controllers perform some form of voltage drop regardless if the setting is at 100%

If I can recall, the min this pump was able to run before i got an N/A message was about a 1200 RPM. I agree with wlw about it not harming the unit, if anything it should prolong the life of the motor inside the pump.

The diode in the fan controller is most likely an anti-surge diode connected in reverse parallel to the output to protect the power transistor from back EMF from the motor.

Dude, your right... You sir know your stuff! Just looked and traced the paths on the circuit board it self.

Do you guys think the H100 is worth it? Or should I go with a HSF like DH-14?

Welp my custom cable arrived today. This should do the trick nicely to run both power and the RPM feed to a header on my fan controller. I'll get it connected up tonight and see how it goes.
