    Re: Computer fan noise and maintenance

    ^ What a treadmilll uses could depend on the manufacturer and where it is used. If it is in a gear housing then it's probably 85W petroleum gear oil. That would work, but won't as readily soak into the porous bearing.

    Silicone oil is rarely used for lubrication except where petroleum oil would break down components or in an extremely high temperature environment where it better retains its viscosity.

      Here it is.

      I think it is silicon based. What is your opinion?

        ^ Based on (lack of) color it does look like it may be silicone based, but I can't read the text on the tube. Where is it used, which specific parts of the treadmill?

        I wouldn't use it on fans, but in an emergency it might keep one running.

          My favorite for fans is Tri-Flow, it's brought a lot of seized fans back to life too

            Ah, I wish I'd found this thread a while back when I was researching grease.

            So far, I have some of the ol' PTFE Super Lube for plastic gears, and plastic/metal lubrication, and some Wal*mart stuff - Supertech "Moly-Lithium" grease (which reportedly has very little Moly at all).

            What I'd like to know about are worm gears - it seems to me that these parts are likely to experience some wear that could be prevented with the moly-additive grease. I just put a little on the worm gear of a floppy drive, which I hope is best for the job. I've also got some worm gears for optical drives that I'd like to lubricate. In both cases I want to avoid using a too-heavy grease so that the drives don't seize (but that's probably not a major concern with worm gears after all).

              For worm gears in optical drives, you're supposed to use lithium grease... I know this because there was discussion about it years ago with regards to certain xbox360 drives...

                Re: Computer fan noise and maintenance

                There are a few potential wrinkles here:

                - Some worm gears are brass, some are something like brass-plated steel, others are steel or some other shiny metal...

                - There's also additives to consider...molybdenum is the most common one.

                In some cases the chemistry of things matter - but I haven't found any record of lithium, or lithium with molybdenum, causing problems in commonly used metal worm gears.

                The synthetic silicone stuff seems pretty good and versatile - it's just an open question (for me) as to whether it competes in this application, even with the PTFE additive.

                As an aside, the Wiki reports that there are some PTFE (Teflon, Syncolon) types being produced now which also have molybdenum for extra lubrication.

                This is really promising, too: "By current calculations, a switched-off molybdenum disulfide transistor would consume even as little as several hundred thousand times less energy than a silicon transistor." - R&D Mag

                  Re: Computer fan noise and maintenance

                  I think there is a lack of concern in this thread as to the comparability of lubricants with non-ferrous metals. Transmission and gear oils are good because they are meant to protect and prolong use of non-ferrous metals, especially brass and other yellow metals. There is an exception however, as specs such as GL5 call for extreme pressure additives, which have the unfortunate effect of degrading yellow metals

                  To reiterate what I've posted, before I have always used Dexron III and never had to relube afterwards.

                    What about this oil type? I bought it today for 2.5euros. Is it the suitable for fan bearings?

                      Re: Computer fan noise and maintenance

                      Looks like seweing machine oil type (unlikely that it is genuine "Singer" like the seweing machine brand, but anyways). If so, it will probably do fine. Sewing machine oil tends to be a bit more runny, but it doesn't dry and (at least IMO) it works fine.

                        Yup. I've un-stuck and lubed a few fans with sewing machine oil before. I usually use chainsaw lubricant, which is just a bit thicker, but that works fine too.

                            Even those fans with that chunky, pasty, "gloppy" grease, salvaged from junked Deers (or cheap cases), run for years with this, after a full disassembly/clean/relube.

                                      I think Globe fans mix some of that with their oil too, cause they get stuck way too often.

                                      I just found a (nearly) empty bottle of motor oil (new) in the garbage room at the condo I live at for college. There's probably just a few grams worth of oil left in there... but good enough for a lifetime fan repair. Oh yeah, it's synthetic too. 5W30 or something like that IIRC.

                                        my system is nothing special. i use a Icute 750w modular PSU. This has a very quiet fan.
                                        in my case i have a pair of arctic cooling 120mm case fans. these are fitted using rubber mountings to stop the case vibrating. i also run them at 7 volts using an inline resister between the fan and board connectors. when it comes to cleaning them i use a half inch paintbrush with the bristles cut to half the length. i have never needed to lubricate them in the 5 years they have been in the case and they are still extremely quiet.
                                        My CPU fan is an Arctic Cooling Freezer Pro 7 Mk2. the 90mm fan is rubber mounted as standard and even at full speed the fan noise is acceptably quiet but at the lower settings which i tend to use the fan is hardly audible.
                                        if i ever need to lubricate a fan i use a special oil used to tune high speed multiplier fishing reels which spin at speeds in excess of 200.000rpm (yes you have read right) during tournament casting. the oil is called TG'S rocket fuel. you should be able to get it from most UK angling shops or ebay http://www.ebay.co.uk/itm/TGs-Rocket...-/130820196698.
                                        I use the red grade but red or tournament grade will do the job

                                          Recently, picked up a Thermaltake A4021 for $5, and it was obvious the bearing was dry. Apparently, these were notorious for not lasting, very long at all. I chalk it up to inappropriate lubricant. I cleaned the bearing with alcohol and relubed it with Redline CV2, and it's flawless... and will probably last, forever.

                                            RTX3090 working fine but fans not spinning
                                            by emil_t
                                            Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....

                                            HP1955L Buzzing noise & interference
                                            by stvhop
                                            Hello, This is my first post so please forgive me if I miss out some vital info.
                                            I have a problem with my HP1955L monitor from 2005.
                                            The first thing to say is that it is still basically working, ie the picture is fine.
                                            However it makes an electrical buzzing sound. I know all monitors make some some of hum, but this is louder and more of a buzz.
                                            The volume of the noise seems to be dependent on how hard the monitor is working; switched on with a blank screen -> no sound; small dialog (like OSD only) -> minor buzzing; full screen picture -> loud buzzing.
                                            ...

                                            Removing electrical noise introduced by fan
                                            by tony359
                                            Hi all,

                                            I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.

                                            Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
                                            1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
                                            2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line....

                                            Onkyo TX-SR805 noise in one channel

                                            Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

                                            Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

                                            There's some logic behind it. As soon as I select an input I get only left...

                                            i recapped the entire foxlink psu with rubycon caps of the exact uf needed. i also purchased a delta psu to see if the different brand would change anything and it did not. i recapped the entire motherboard except for about 5 of the 22uf caps. i used rubycon on everything except the five in front of the processors. i used 5 nichicon polymer caps there. i soldered a wire to each screw hole of the psu and soldered one wire to the metal outer shell and one to a screw hole on the motherboard(to make sure it was all grounded well). i also recently tried disconnecting the power cables from the dvd drive...
