The collected works of anotherlin

Hi everyone,

I'm trying to change my noisy Fuel fans for some silenced PC fan.

I'm first trying to exchange the big 120x120mm fan with a Noctua NF-S12-1200 fan. I've checked the spec, the Noctua should be able to pull out enough air.

When I plug it into the Fuel's motherboard and turn on the computer, it just doesn't run. Are the fans of Fuel using the standard 3 pins, as the one usually found on PCs ? I've checked the Noctua on my PC, it works just fine.

I was wondering if the L1 controller is not the problem. The Noctua works at low RPM (1200 only). Maybe it is considered as an error or the L1 tries to drive it at higher speed and the Noctua just does not want to itself on. I've checked the L1 controler document ( http://techpubs.sgi.com/library/tpl/cgi ... /ch03.html ) but I was unable to find the command to set the fans' speeds.

Any idea ?

Regards,

Ok, I'll be sure to check the wiring. But the Fuel probably uses all the wires because it has environmental monitoring.

Indeed, the wiring of the Fuel's fans are not the same as PC. I rewired the Noctua and it runs fine.

However, how do I turn off L1's environmental monitoring during boot time ? I didn't have time to do much tests (got to go to work) but the Fuel shuts itself down during boot time auto-test.

Ok, I've wrote a small C program to extract a file.

I tested it on fx.64 of my 6.5.30 overlays and it works. My fuel is re-installing right now!

Right after the offset, there's two bytes (big endian) with the size of the file name (not \0 ended), which can contain directory path.
Then we have the .Z file.

Why haven't you told me before ? I wouldn't have written this crappy program, if there was already one doing it right...

I have a 180MHz R10k single processor O200 I want to get rid of, if you're interested, I can part it.

Did you feel one? Sorry to disappoint you, this one is for a different project.

Can you tell us what's all about, unless it's top secret ?

How about the noise issue ?

I mean I own a O200 and the 3 (huge) fans are so noisy that it's impossible to work next to it.

I'll confirm that. I've two SAS 15k5 Seagate Cheetah, they're almost silent. They make an SCA version, you check it.

I used to own an iBook G4 1.25GHz and I sold it (300 euros).

I don't think it's a good idea to buy a G4. It's not slow but the response time is not good. Safari and Firefox run ok, but not as smooth as on desktop PC.

For $949 you can get a MacBook featuring a dual core processor, quite good accelerated graphics, and 160Gb hard drive. It can pretty much replace a desktop PC for non computation intensive or gaming applications.
