Hi its not big per-say :D

just i want to replace my CPU fan from the stock one, because im
getting heats of 52*C+ when playing games like CS; S

Just the last time my bro tried to replace the stock fan in his PC it
didnt boot up.

What happenedn to his, was he repalced the stock fan, installed it
correctly, it had a heatpad on the bottom of it, im not sure whether
he put anytihng else on, and he booted up, after everything was
normal, but it didnt boot up. We took it to a proffesional and
aparnlty the bios wiped it self, or the motherbaord was gone or
something of the sort.

I don't want to risk damaging my computer, but the heat is affecting
my gameplay!! if somebody couldgive me safety precautions or what not
to do when installing a new fan, i woudl appriciate it, i woudl also
appriciate if someboy could guide me to a good AMD athlon 3200+
fan/cpu heatsink, which would birng the heat right down!!!

THANKSSS!!!

if you can help me pm me or add me to msn messenger,
(e-mail address removed)!
 
I wouldn't worry about the heat of the processor going over 52C. I've
seen mine go over 60C. The Athlon was designed to withstand a maximum
of 90-95C.

Really what is much more important than the temperature of the CPU is
the temperature of the chipset. Those chipsets aren't designed for high
heat, and I've noticed that data becomes unreliable when the chipset
goes over 40C. It's the chipset that you really should be monitoring.

Chill! [pun intended] This is not a problem. The AMD XP
3200+ is spec'd to 85'C, and even with the usual (large)
offset between die and mobo sensors, you are almost certainly
within spec. Furthermore, even if you are overwarm, AFAIK the
K7 doesn't have thermal throttling (unlike the P7 Pentium4)
so will just run hot, not slow down.

Then don't do anything beyond your skill set. One simple
thing is to feel the case back, sides and check exhaust
fan temperatures. If any of these are overwarm, then you
may have poor case airflow. Fix it by making sure all vents
have clear, fresh airflow. No carpets, papers or jamming
into corners that force recirculation.

If you feel comfortable removing case covers, you can blow
dust out from CPU & GPU heatsinks, power supply and vents.
Mine (on 24/7) need blowing every year or so. YMMV. Canned
air is sold for this purpose. You might also look at case
airflow from the inlet vents to the exhausts and make sure
there are no obstructions like flat ribbon cables. If there
are, you may be able to move them gently out of the way.

How, precisely? You're a gamer, so I presume you've got
an advanced/expensive video card. These can produce a lot
of heat, and cause lockups if they're not properly cooled.

You may also have acquired a software problem. MS-Windows
is a popular target for various trojans and worms. All
operating systems without QoS can run into trouble with
bandwidth hogs like poorly-configured P2P apps.

I'm not sure about more recent chipsets, but I know the
i440BX is spec'd for 105'C. People did report that cooling
it helped, but I'm not so sure. It might need a heatslug
more than a heatsink.

Or a problem may be voltage regulators and increased
noise/crosstalk on those 64 bit wide memory busses if
the substrate has a temperature gradient.

The gaming problems i get arnt in the online games, its all motly in
offline games, i got alot of sluggyness in half life 2 single palyer,
and the poitn was, ive repalced my GFX cards stock fan, because lets
face it, that small thing did nothing, and i have an arrctic cooling
one, and ive got the ati softmod

i tihnk itsa all down to my gfx card i suppose, an ati radeon 9500
pro, doesnt cut it now adays, the softmod has suppsoedly made it run
at 9700pro

either way ill look into it
also, just lie kto say, the cpu cooler repalcement is beyond me, im
always doing stuff in my computer, jsut after what ahppened to my
bros pc, kinda made me warey of what coudl happen.

eitherway thanks all :D

105C or 105F?

If it is 105F then that equals 41C, exactly what I was talking about.

All of them. If you start seeing a chipset start approaching 40C then
you should be worried. Most of the time, they will hover around 30-35C
they usually don't go up or down much with processor activity, but they
do go up and down with dust build up.

No, and absolute maximum of 105C Tcase. See section 2.2:
ftp://download.intel.com/design/chipsets/datashts/27321903.pdf
"The 82443BX is designed for operation at case temperatures
between 0C and 105C."

Most electronics are speced for a *least* an 85C Tjunction, with some
power devices (like the IRL3103) going to 175C Tj. 100C isn't unusual
at all for Tj on commercial grade electronics. PCs I've worked on have
a 45C Tambient temperature limit around the electronics (55C Ta for the
drives).

Nonsense. We spec. in embedded boards with VIA chipsets that'll do 60C air
temperature for example. The actual chipset runs 15C or so higher, and
they're the same chips that would be used in any motherboard. See
http://www.netcomipc.com.tw/product...=1813&osCsid=4ee9a698c5f7c499db9b7ff43202192b

If you're seeing boards become flakey when the chipset temperature reaches
40C I would suspect the board design, not the chips themselves.

Hmm, Yousuf where do you get the chipset temperature from? From what I
see, there are usually at most 3 readings, CPU, Case and PWM/VRM, all
of which can go above 40C in my environment.

I consider the case temperature to be a analogy of chipset temperature.

The systems I did stuff for had 38.6 degrees and 7000 feet altitude as
environmental maximums. I always thought of it as an un-airconditioned
office in Mexico City in the Summer.

What case? Yousuf, I think you'd better study temperature measurements a
little closer. Don't trust whatever the motherboard is telling you. The
*fact* is that an *ambient* temperature around the chips of up to 45C is
just fine. In fact it really doesn't matter what that temperature is.
It's only the chip's junction temperature that matters (much). Indeed the
junction temperature is a reliability issue and that can be traded off for
function (or marketing).

All the PC class hardware I've worked on was 45C inside the case, around
the motherboard (55C ambient around the drives). IIRC that was at a
maximum of 5K'. You've been pampered. ;-)

The 38.6 was outside the case. Class B extended to be exact. What happened
inside the case was our problem.

PC component manufacturers worry about what goes on inside the box. The
integrators have to worry about the box. Even the FCC recognized this
difference six-ten years ago.
 
Ykhan, while it's true 90 -95 deg C is the quoted maximum temp that an
XP is capable, just how long one will last at that temp is something I
certainly will not be testing on my gear.

The MP cpu will go to 95 deg C roughly 5 deg C more than the XP.

Of course if someone has the urge to experiment, along with many
others I would be interested to know how long they will last at a
constant 95 deg C.

I dare say that even with the HS fan turned off a system may still
survive if the case ventilation was up to scratch (side off) etc but
at around 75 -85 deg C as a rough guess, I have changed fans without
shutting down a system watching the temps, never went past 50 deg
C..

I doubt that any cpu would last more than 5 minutes at 95 deg C and
still survive it.

I have seen an 1800 XP pop, the builder showing me his technical skill
had failed to install to the cpu the HS still sitting on the bench, it
lasted less time than he could reach down and push the start button
and wait the 4 seconds.

Remembering that even though the system is shut dowm there would be a
lot of residual heat, so even if you pulled the cord it still may
pop.

About 5 - 6 seconds and they explode.

Interesting.
