Please log in for more thread options My system fan came out of a compaq server. I don't know too much about this new machine. Some basic info I have gathered about it is as follows. Boot error message: "Secondary IDE Channel no 80 conductor cable installed" Microstar MSI KM3M-V (MS-7061-01S) VIA Pro Savage DDR KM266 PRO CHIPSET VIA VT8237 chipset VIA 823 Board drivers downloading now from : http://support.octek.com.au/Update/VIA/V823x.htm Prompts me to insert "Intel Ultra ATA Storage Driver Disk" The user manual appears to be at http://www.fixya.com/support/p568204-msi_17154bb019u_motherboard/manual-15311/page-25 I'm having two problems right now. Only Linux sees my 2 DVD drives. Windows 98 doesn't know they are there. I'm assuming I can get this fixed with the correct drivers and/or new IDE cable. The bigger problem is the system fan. The end of the plug has 5 holes. The motherboard connector CPUFA1 plug only has 3 thingies. The CPUFA1 plug appears to be located right next to the memory. My fan's plug can't reach all the way over there. Even if it could, it has too many holes. Am I going to be able to use this fan????? dos-man | |||||||||||||

This is a fan for an ML310 (of which there might be five generations). In one Ebay advert, the fan was rotated so the hub was visible. Unfortunately, the smaller part number printing was unclear, but in big letters the fan was identified as a Nidec Beta V. The link is to the datasheet for the fan. As you'd expect, there are cabling options for the fan, so there is no way to know what options are on the cable. To go further in the search, you'd need to use all the info printed on the hub of the fan. And even then, the fan could be a custom design only for Compaq. Part Number: 287179-001 http://www.nidec.com/fanpdfs/ta350dc.pdf Cabling options include the following: Alarm/Tachometer/Thermal Speed Control/PWM Speed Control Alarm = likely locked rotor detection = no connection to this pin is needed. Tachometer = two pulses per rotation, open collector. For a chassis fan, monitoring of fan speed is not essential. If a CPU fan, then yes, this should be connected. Thermal = could use a thermistor. It is more typical in the computer industry, to buy a fan with a thermistor inside the fan hub, saving on having to do it externally. So maybe this option is not on your fan. PWM = currently used on Intel retail CPU fans. 25KHz square wave driven by motherboard. If open circuit, fan runs at max speed, so this does not have to be connected. +12V/GND = At a minimum, the fan needs power and ground to run. The Nidec datasheet mentions red and black as colors used on their two wire cable. But we can't know whether that color choice would be used on all possible cable assemblies or not. The cable assembly may have two ground wires, because I think I see two black wires. That leaves only three more to figure out. One will be +12V. One could be PWM. One could be tachometer. So that doesn't help really, but it is a start. All you really need to do for a start, is identify the +12V and ground pins. You don't need to connect the tachometer signal, as it is a chassis fan. On the motherboard end, the connector has +12V, GND, and tachometer input. The +12V will offer a limited amount of current, and truly monstrous fans should not be powered by the fan header. (For example, I have a 12V at >1 amp fan in my current computer, and to protect the fan header, I
take power for it from a Molex disk drive connector.) If you exceed the
allowed current, either a copper track burns out, or a transistor on the motherboard gets fried. There is *no* fuse in that path. Some motherboard manuals have a pinout for the header, and they may mention the allowed current flow. GND +12V Tachometer X X X ------- (keying tab) HTH, Paul | |||||||||||||

Win98 should see them as drives, without drivers. It was only the really old stuff that needed a driver in Win98.

Sometimes you can peel back the label a little, if the wires attach to the side the bearing opening is on, and see marks on the PCB to denote the power lead and ground. Other times you have to guess and try momentarily applying power to one of the colored leads to see if it spins. FWIW, a different model of Nidec Beta V here uses red for power, and of course black for ground. As for the addt'l positions on the connector, once you'd desoldered or clipped off the unneeded wires you can try slicing off the unneeded positions on the fan's plastic connector block with an X-acto knife or similar. Finding out whether one of those addt'l wires is an RPM lead will be a bit more work, personally I wouldn't worry about it too much if the fan isn't very worn as Nidecs tend to be very good quality and unlikely to be an early failure point unless it has very high RPM. >dos-man

Sorry, I couldn't get back to this thread in a timely manner due to my work schedule. At any rate, I followed your advice and put in a new fan. I also mounted a smaller fan at the bottom of the tower for extra cooling. These Compaq servers have steel towers and I'm told it gets hot inside there. It's a cool 85F right now. I got the machine to finally recognize the DVD drives. Everything is looking good except for some minor probs with USB flash drives having two entries in "My Computer". And the new 1 gig PNY camera cards I just bought are only showing 570 megs of available storage space on them. Those are issues for another day :) dos-man | |||||||||||||
