   Last winter I scrounged up enough cash for a cpu upgrade, not much but I
did manage to get an xp2100+.(the older version)  Now this has been a very
mild spring so the average temps have been in the 60 to 70 degree F range.  
With the racing box in the ba***t, I didn't need to worry about cpu temps
much...even tho the average temp was 55c.   But now that summer is starting
to heat things up, I decided it was time to get a real heatsink...Slapped
it on and it actually was NOT an improvement...I must not have gotten the
heat-goop(artic silver) on properly cuz the only way I can get the system
to boot without*** is to underclock the 1700mhz cpu speed to 1300.  
Then with the lower settings I get pretty good results...so NEXT I decided
a beefier fan was in order...still can't boot at the higher setting but the  
cpu temps are avgeraging 44degrees...which is good...trouble is...this dang
high velocity 80mm turbofan is making me deaf.  
   I used to keep the box cool with a big desk fan blowing into the open
side of the system, but with the new fan I don't need that anymore..but
this turbofrickinfan is just as noisy as the desk fan and thats with the
case closed up...
  I saw case-liner noise insulation, but what real good would that do?  
since most of the noise is comming out of the slots for the front and rear
case fans.  I'm thinking it's time to move the system case under the desk
and find a nice thick quilt to throw over it...
  What you say?  Got any ideas???  WHAT????

Hey Dave, J.Simmons outlined his water-cooling install a few threads down.
I wouldnt think an XP2100 would need it, butttt. ;)

   From what I've heard locally, the older version of the 2100 is the
hottest of all the amd cpu's.  I sure hope so if I ever upgrade again. :)

There's no need to have a noisy CPU fan these days unless you're into
serious OC'ing, companies like CoolerMaser and GlacialTek both have very
quiet HS/Fan comos rated for AMD's right up to the 3000+

The GlacialTek Silent Breeze for instance is rated at 19db and covers
all AMD's up to 2700+, the Igloo 2310 is rated at 25db and covers all
AMD's up to 2600+, there's also PRO versions of the Igloo's but those
are far more noisy  

Beers and cheers

Dave...i did exactly the same as you last year and i lasted a month before i
just had to get rid of the noise.

Swapped the Delta 80mm CONCORDE fan for a Pabst 80mm 19dB fan.

System is 3 degrees hotter but at 42 degrees C im well cool overall.

Whilst on this subject my best mates story will tickle you.

He had heat problems and at about the time i suggested water cooling or
maybe an SLK800 with Delta 80mm he finished building his boat that they were
going to be living on.

So i helped him moved it all on into its ready built compartment(he built
the whole boat himself,it arrived as a steel shell),we rigged it all up and
after about 30 mins i thought i'd check his temps.

Well it was 16 degrees COOLER...!!

For the simple reason it was up against the cold cold steel that had cold
cold water outside...LOL

Needless to say it saved him a few and he hasnt lined that section as he
was going to but left it bare to aloow that cold to fight his heat.

Good luck Dave

i installed sound absorbing foam and it does help.  i went to the local foam
store and asked them what was best for my situation and got some 10mm foil
insulated foam.  the foil's to reflect heat.  AU$20 for 1mx1m.

i covered both sides, top, bottom, 1/2 the back and empty 5 1/4 bay opening on
the front.  got enough foam left to do one more case as well.  i think it
helps absorb the high frequency 'whine' from fans and HDD.

i also bought a antec truepower PSU that controls the case fan (x4 80mm)
speed.  this helps a LOT.  and i've got a vantec aeroflow HSF for my XP2400+.  
a faily quiet fan but it cools well.  i don't overclock so its perfect.

if i've got my 2 other computers running at the same time, i can't tell if the
2400+ box is on or not :)

You can't give a deaf man No for an answer.

Dave..

Seems to me that you are trying to "fix" the wrong problem.  Whatever is
making your CPU refuse to boot at normal FSB and multiplier, is probably
also the reason it is running hot.  I have an XP2100 running 42-44 degrees
with a "retail fan" and I didn't even use AS goop, just the basic garbage
that comes on the retail fan already.

If I were you, I'd go to any of the AMD/cpu tech forums and get the main
problem fixed first.....then see if the heat issue doesn't disappear
automatically?

36c, even under a full load, the PC just heats the room up so well that
I've had to install a noisy AC unit. :)

   Well with the oem fan I would boot to temps around 54c.  Then with heavy
gamming it would creep up near 58c.  But as the outside temps have begun to
get near our norms of high 80's the cpu temp was climbing too.  So I put
the new heatsink on, and I'm not very good with that sort of detail...I'll
be having one of my son's techy friends re-attach it shortly.   But now
with the turbofan, I'm averageing 41 to 44c but at the lower clock
setting.(I haven't benched the lower clock speed yet, but sim performance
is NOT that different--odd)
   I agree there is probably an underlying cause, I would suspect it's
related to my clumsy efforts to put the new heatsink on properly.  Once I
have somebody re-do that, I'll dig into the rest...thanks..

ok, sounds a bit weird. hmm....have you tried reseating the heatsink, cos if
it ain't on properly (it may be difficult to tell) it will get pretty hot :o

try reseating, but if it don't work then you may have a problem with case
airflow. I would recommend an inlet and outlet fan to get the air moved.
that will reduce temps by at least 5C.
that's all i'll say for now, but if you need more help then ask again :)

Is everything set to detect the cpu automatically?  Was wondering if
voltage settings were higher than normal.  That can push the temp up.

   It seems POWER was the problem.  I managed to get the full speed back
into the chip by upping the vcore voltage from 1.75 to 1.775.  I just did
20 laps with the cart mod and got reasonably good framerates without any
problems.  The extra fan was probably enough to tax the Antec 350 watt ps.  
so giving a little more juice seems to have solved the problem.  Now, with
the case closed up tight, and the ***y noisy fan running I am getting
temps in the upper 40's without a load and around 53c under a load.  Given
it's nightime and under 70degrees F in this room right now, So I"ll reserve
final judgement till I can measure the temps on a hot hot day.      But
this is still much better than the temps I got with the OEM fan and the
case opened up with big ol helper fan blowing in.
  Guess I'll think about a speed controller now to quiet the fan some in
low load situations.  night all....

Just a note about the paste: a common mistake is to put too much.  You
should actually put very little, a very light smoky film at beast.  It
shouldn't interfere with the contact between the HSF and the CPU, it
should only fill the microscopic "cracks".  People have this impression
that Artic Silver is a fantastic heat conductor, but in fact if you have
too much it will hamper the trasnfer of heat between your CPU and HSF.  
I've done a lot of tests myself with different amounts and definitly with
just a little too much my temps start going up siginificantly.  Lapping
your heat sink (and perhaps even your CPU) can help, but if you don't
have the right tools, don't do it because you might actually make the
contact worse.  Again, the important thing is to maximize the metal to
metal contact between your CPU and the HSF, the paste is only there to
fill the microscopic "cracks" so that contact is continuous.

Dave...are you just ignoring me..?

Swap your fan for a quiet fan...job done.

Pabst make quiet fans for 12 here in UK.

12 to cure the noise....am i still worth ignoring..?

Sheesh...
