Re: DIY voltage drop

Let me summarize that again: * A voltage regulator is a cheap solution that looks ugly on a wire. * The earlier ohmages I chose should already do the trick provided the fan still starts. * A start amperage of high value might burn the first resistor if it takes too long * Raising the resistor values...

Re: DIY voltage drop

Ah. I regret not just going ahead with my voltage divider plan: I think it would have worked :). Today I seem to be going for a voltage regulator but the annoying thing is that you have to get a fixed value (or get a variable one with a potentiometer to go with it, which then has to be a form of tur...

Re: DIY voltage drop

Someone wrote in 2014:
A resistor divider circuit is for creating a voltage that's a fraction of an input
voltage, and expects to be driving a very high impedance load (otherwise the
divide ratio is influenced by the load).
which is basically what I described in my post.

Re: DIY voltage drop

Lol I think I have already said it. It's a graphics card fan that won't honour the Maxwell architecture BIOS values (that I modded, and which it recognises, to some extent) so it is stuck at a base minimum of 1500 RPM and has a fan that can do reportedly do 3600 RPM max. It uses JST PH connectors th...

Re: DIY voltage drop

I'm gonna have to stop thinking because I'm not doing very well at it. The maximum resistance minimum voltage drop is 1/4 (for these figures) at 3V up to a fan voltage of 9V. The speed reduction is then less pronounced at lower speeds, but more pronounced at higher speeds. 3V of 12V is still 1/4 low...

DIY voltage drop

I am very inexperienced with regards to electronics and solderings. It seems most if not all voltage reduction cables just have a single resistor on the wire for the yellow (+V) or red (+V), depending on which you have; the +V cable has a resistor to it. If you're talking about 2 resistors Ohm's law...

Re: CS550M alternatives

I worry about this. I have had a Corsair VS350, a Corsair RM550, and a Corsair RM650i and I have never heard these sounds. The CS550M is said to be not very well engineered. If you compare pictures of the internals of the CS550M and the EDGE 550 for example, the difference is outstanding. In how wel...

Re: i still use windows xp on the desktop

I would agree with that. It seems pretty dogmatic to say that you "need" Windows 10 for anything other than what it really introduces, which is like the Windows Store and nothing else (for me at least).

Re: Current state of fan (brands)

In general I think a regular non-PWM fan will run fine on a PWM header. PWM probably just runs on 12V by modulating something else, so you won't have issues running your regular fans but you will have to check whether the motherboard also supports voltage control over the yellow wire. Some motherboa...

Re: Cooltek "Silent Fan 120" little review

I must rectify a little bit. It seems that when I did the motherboard BIOS readout (from the BIOS screen) of the fans I had not put them behind a fanmate2, but I'm not sure. In any case, that reading of 800+ RPM at the lowest voltages is not correct. At 5V the fans spin at 580 RPM. With another cabl...

Cooltek "Silent Fan 120" little review

I purchased 3x Cooltek "Silent Fan 120" (non-PWM) to test them. They are cheap enough to test in 'bulk'. At 1200 RPM (or 12V) (likely, my BIOS claims the IO chip so my software can't read it, have to see if I can turn that off) the thing is definitely audible at over 3 meters even in a noisy dayligh...

Re: Current state of fan (brands)

I think that would depend on whether these brands change hands (or management). Nexus was acquired by a US company and hence do not ship to Europe anymore. Bit strange, they were a Dutch company so I guess they just bought their intellectual property and brand, and manufactoring contracts. They disc...

Current state of fan (brands)

So in the past there was the Dutch brand Nexus that was cheap and I just bought every fan from them and never had issues. They were normal, decent, and no frills to them. They looked good too, but very decent and normal and regular. Most of the brands you see in the stores try to be special or "cool...
