A plain old 300w ATX one modified so it stays on unless I flip the switch and give me only 12v. Next one I hack up I’ll get other voltages leads. The fan in that PSU gave up the ghost so I’m using the jet blast off this fan to cool the internals.
Not many of HP’s servers take these type of fans. C7000, C3000, and D6000. Any other servers take plain old black box fans but highly souped up ones. Your typical computer have the typical 4 cylinder eco engine of fans. The servers beside the three I mentioned have the Hellcat engine of fans. Those three have the afterburning turbojet of fans.
C3000 - 6x fans.
C7000 - 10x fans.
D6000 - 4x fans.
The Cx000 servers are dozens of individual computers in one assembly. I’m not clear on how they work and whether they can be daisy chained and the operating system see them as one computer but tons of memory and cores. Clearly it’s a must for these to have more than 4 jet fans to cool all those cores.
The D6000 is just a bunch of hard drives in one assembly. 70x desktop size drives. Typical computer is one or two desktop drives within them.
Before anyone (usually a noob whenever they discover an old thread on here about space issues in LG) asks, no you can’t simply install LG in one of those machines in one of the admin’s basement and have more space for more pics. Those things are super thirsty. Both in electricity and bandwidth. And absolutely NOT cheap to run.
The blades HAVE to be metal as I read the fan spin them at over 50000rpm! You’ll lose your finger if you get it in there. You can stop the slower fan blades easily with your finger. This one probably won’t even slow down as it slice your finger to a nub.
