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.
malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
