Hey,
Is anybody "crack down" the monitoring signal on Alpha server cpu fans?
A lot of people tried to put stock, generic cpu fan on their alpha cpu card without any luck. the monitoring line(3rd pin, blue or gray wire) is most likely different on DEC specific fans than generic
Leaving little option then buying:
"Refurbish",
"Dustoff",
"Used",
"Like new",
"Reconditions",
Fans from 3rd vendor at high price..
An used fan, will always be an used fan..
Those fans are so small, that ball bearing, sleeve, shaft wear off and cannot be really "reconditions".
There are only a handfull of standard for fan monitoring, (RPM, Temperature, Cycle/4...)
But it looks like DEC happilly stay away from those for their own reason (??---$)...
Example :
DEC P/N 12-24701-34 OR 12-49995-01 (P/N seem interchangeable)
OEM P/N: Shicoh ICFAN 0610-12DV --> last letter “V†seem to be specifict to DEC
DELTA ELEC, AFB0612HA –S164 same for the –S164
So my question (again)
Is anybody "crack down" the monitoring signal on Alpha server cpu fans?
Or found a sources for “NEW†at reasonable price?
I will assume that hte fan in question is for a DS10?
I have not yet found any replacement that will work. Most won't fit onto the heatsink properly. I refuse to spend $100 for a fan that should cost less than $10. I was able to acquire another unit with multiple spare parts rather than spend rediculous money for just a fan. I might suggest the same for you. DS10s are available for short money on Ebay. BTW: In the last 10 years with 6 DS10s in production, only 1 has failed and that was due to a bad fan. Not a bad track record...
The fan on my DS10 was pretty noisy when I acquired it. The bolt pattern on mine is the same as a standard 80 mm fan, though the OE fan was thinner than any I had on hand.
I replaced it with a random fan from my spare parts collection, a Datech DB9733-12HHBTL. It sucks air up through the heat sink and exhausts it out the back of the case. I had to switch the wire positions on the plug and trim the exhaust end of the shroud but it works very well and is surprisingly quiet.
