I have two Papst synchonous motors in turntables from the good old days. They were the premium motor of their type in 1960. Unfortunately, the company won't send me a diagram of the things. I want to take them apart. I figure that they might like to be oiled again about now. Richard |

I must have had beer on my mind when I wrote that. Or maybe in my belly! I really like Papst fans. Good engineering. A bit of lube on your Papst turntable motors after a several decades might be a good idea. But only if they need it. |

Roaring? Actually the noise they make is rather benign. Mr Bottoms, of course fans can make a significant noise. Nowadays they are more often high rpm and make even more noise than ever especially as cpu temps are so high. I would have to disagree with this, nowadays more than ever CPU 'sink fans are larger and lower RPM, it used to be, only a single-digit # of years ago, an 80x25mm fan was considered quite large for a heatsink. Today 92x25mm fans are found on the low-end budget heatsinks and 120mm, sometimes even a pair of them on higher end heatsinks - these larger fans not turning very fast at all, modern decent heatsinks with heat pipes can keep a 100W CPU cool enough without such fans even spinning at 1000 RPM. Component or case fan, one with sleeve bearings sound ok to start with then get progressively a lot noisier. And I just won't believe all your fans were Pabst or equivalent. http://www.silentpcreview.com/article63-page1.html I would think that constant speed changes would be more annoying. Besides, it is better for the electronics if it runs as it was designed to do. It is better for what electronics? Fans are not specifically designed only to run at 12.0V, they are merely rated at that voltage because it's a common one to provide a context for other ratings such as current or RPM. A full proper fan spec sheet lists the voltage range any particular model should run at, typically a range for a fan briefly listed as a 12.0V fan would be about 6V-14V. The range gets even larger for 24V fans, and of course these ranges are only what the fan manufacturer guarantees, many people find the actual range a bit larger. There's nothing in the design of a PC which prevents use of thermal controls. Low revving large blade fans are anything but annoying. As for a fan failing...I would hope you would notice. This is such a in-demand product, I'll just bet everyone is now rushing out to get one, lest they bake their machines. More likely, it itself would be the issue in the long run. A machine baking is usually due to fan failure or not cleaning out dust periodically. We can't control the user's environment or lack of proper maintenance when it comes to cleaning, but when it comes to fan failure the slower a fan spins, instead of at full speed the whole time, the longer it's lifespan. Further the slower it spins the slower the dust accumulation. Throttling back fans helps prevent a situation where one bakes their machine, provided they do as any other situation requires - pay attention to the details in implementation and check the result instead of just assuming one can slow down fans as much as possible without bothering to check the resultant temperatures. If you don't yet have the knowledge or ability to use SpeedFan then leave it to others. There's no need to disrespect it or its users. Indeed, though there is one other risk - relying on software to control system cooling also relies on a weaker link, the operating system on which it runs. Pure (discrete) hardware solutions aren't vulnerable to a system instable from motherboard failure, CPU errors crashing the program, windows itself crashing from one of many causes ranging from OS bug to malware to driver bugs to ... The safest strategy is a cooling solution that doesn't rely on anything else working properly (except of course power getting to it within a safe voltage range), a self contained solution that would increase fan speed even if the rest of the system is totally locked up and inable to do anything but create heat. |
