New HS/Fan = No Boot!

[Martoch]

Okay guys...help me out here...am I missing something or what?


Replaced my old HS/Fan with a new one.

Now all I get is an immediate short beep, followed a few seconds later by a very long continuous beep that eventually leads to my computer shutting down. This is happening right away, before my hardware is detected at all. I've checked every connection twice (even triple checked that the HS/Fan is connected to CPU1...otherwise, it would power off because of the Fan Off Control), reset the CMOS twice, reseated the HS/Fan four times...cleaned off the cpu die before applying new thin layer of Arctic Silver 5...all to no avail.
The new HS/Fan is spinning just fine as are all my other fans (to include chipset). I'm about to slap my old HS/Fan back on to make sure my comp will even boot.

Thanks!

Try hooking up your old fan to the CPU1 and a spare molex connector, or whatnot, and plug in the new one into the spare connector next to CPU1.

It's possible the new fan isn't getting a reference signal out to the motherboard ( or you crushed the processor core )

Just put the old HS/Fan back in...works like a charm.

What gives?!?!?!

That's what it seems like Red...the new HS/Fan is getting power, but my mobo isn't "seeing" it...thus powering off the protect the cpu.

Hmm...now that I'm booted back up, maybe I should disable the Fan Off Control in the bios and slap the new one back in.

Whaddya think?

[RedFury]

didya read my post?

[Martoch]

D'OH!

Um...yes, I read it...it just didn't compute until now.

Sorry, I think frustration took over for a few minutes. I'm calm again.

[Martoch]

BINGO!!!

Did what you said...old HS/Fan into CPU1, new one into CPU2.

Guess I have to disable FOC in the bios if I want to use the new HS/Fan.
Is that safe?



EDIT: WOW, temp dropped 8C with new HS/Fan! Went from 43C at boot to 35C...yay...much more quiet too!


Now...just how far should I OC my XP2000+ with the new "cool" HS/Fan?

OMG the new HS/fan is only spinning around 2500RPM!
I checked it with 2 different motherboard monitoring progams too...do I need to bump up some voltage?

NM, just saw this on the newegg link:

Quote:

Nominal Speed(RPM): 2450

Just seems slow compared to my old one...spun at 7000RPM.

well, the old volcano 6 was a screamer... I had one, and got rid of the fan pronto and got an 80mm adapter for it.

I've got the coolermaster Aero V now ( squirrel cage fan...moi excellent )

If the new fan doesn't give a signal to the MB I would think that it's faulty, perhaps get it replaced. The shut down on fan failure is a Good Thing, though I suppose it's pretty rare for a fan to fail without making that horrible squeaking sound first!
