Probably the same noise level, but I find the humming of a 4D deskside more agreeable than the noise of an Onyx2. That loaded Onyx2 will eventually go into fastfan mode and then you want to run away. I believe 4Ds and Crimsons can spin the fans faster, but I've never seen it happen.
Now this is a deep dark secret, so everybody keep it quiet :)

Weeeell Given my location it does get pretty hot during the summer months, 104F sometimes. Very uncomfortable.
Thankfully these beasts are in an air-conditioned study... However you're right... fast fan mode isn't something to poke fun at.
They really do sound like they're about to take off :P

The huge single fan in an Onyx looks like if it was made to take off; reversing it would probably make it hover above the ground :P

Well the power supply exploded when I decided to get the system set back up again (detonated right after the keyboard lights check during boot). I'll either have to track down a replacement or find a place to repair the existing supply sometime early next year.

Ugh. Is it the black (Cherokee) or silver (Power One) model?

I had a Cherokee that blew up; that was unrecoverable (PCB charred). There are a couple of threads around with my adventures with the Power One model. IMHO the Power One PSU (usually found in PowerSeries desksides) is more reliable and much better built than the Cherokee. They're also very expensive (they're marketed in medical and nuclear markets), and I've always suspected that the switch to the Cherokee PSU (mostly found in Crimsons) was due to cost savings.

I'm pretty sure it's a Cherokee supply; I'd have to double check (it's a late model Crimson though, and I seem to recall the PS is black).

Hi,

jan-jaap wrote:Not really, but there's another way: if you engage that breaker switch and you hear a fan humming inside before you flip the on/off switch on the front you have a PowerOne PSU. If not, you have a Cherokee PSU.

Since this is a 'late' Crimson (original configuration R4400 + RE) my guess is it has the Cherokee PSU.


A fan does come on as soon as the breaker switch on the PSU is flipped on, so it must be a PowerOne. Once the front panel switch is flipped the others roar to life. The manufacture date on the card cage door is 12/94.

Yeah, that was my thinking as well - certainly didn't haggle on the asking price ;)



Earlier it was thought to be the PowerOne one...

That was just a guess of course - I haven't opened the back and actually looked at it just yet (I did say I'd have to double check). Maybe this weekend sometime.
