Re: Lombard L2 failure, was Re: Lombard cooling fan

[Mike McGinnis]

	I also recently had a Lombard 400 CPU having L2 failures. I decided it 
was toast anyhow so I popped off the heat-sink on the CPU, cleaned off 
the chip, reapplied a small amount of thermal grease and reinstalled 
the heat-sink. The temperature of the CPU dropped 10-15 degrees. I 
wonder if I had done this prior to the computer having problems would 
it have saved my CPU.

I also can use a 400 CPU if anyone has one laying around.

Thanks, Mike

The reason I'm asking is that my Lombard 333 (O/C'd to 433) with 512 
MB
running X.3.2 has been running at 100% CPU and heavy disk and CD
activity for about an hour now and the fan has yet to come on even for
a second.  I lifted out the keyboard and the heat sink is 
uncomfortable
to touch, especially over the CPU.  I realize that this suggests that
the heat is being removed from the CPU, hopefully effectively, but I'm
concerned that it is getting too warm.

Now that I've had the keyboard open for a few minutes while writing
this (I have an external keyboard connected), the heat sink is
noticeably cooler.  This really makes me wonder if my fan should be
running...
	I wonder if that might be what leads to the failure of the L2 cache
in the processor, as is the problem with mine (According to Gauge Pro, 
mine
runs at 55-65 Celcius).  Is a fix possible of something like this, or 
am I
stuck with replacement of the processor?  Anyone have a spare 333 or 
other
replacement processor on hand?  TIA.
