Max temp & normal running temp (Dual Core)?

Hi,

I have recently installed a Pentium Dual Core 5.6 Ghz processor on an Asus
P5VDC-MX motherboard, with the side cover off the PCand under light load the
CPU temp is about 40 to 45 Deg C. when the side cover is replaced the temp
rises to over 60 Deg!

What is the max temp this processor will withstand and what temp should I be
aiming to run at.

Thanks in advance

Graham

By the way, Intel does NOT produce a 5.6 GHz CPU in any flavor. (Do you
mean 2.8 GHz dual core?) But your dual core CPU has a limit of 65 C. You
need better cooling.

Follow these steps:

1) Clean out all the dust inside fans and heatsink using a can of
compressed air

If that doesn't work

2) Remove the heatsink. Scrape off the old thermal paste, apply a new
coat, and reattach the heatsink

If that doesn't work

3) Add more fans (or anything to improve cooling) and get a better
heatsink/CPU cooler

Before doing anything, run the computer with the case open and see
whether all the fans are spinning, and whether any of the wires are
making contact with a fan.
I had the same problem, only worse, my temps were around 85C! For me,
the first step reduced the temperature by 35 degrees celsius!!, Now my
temperature is good.

Hi,

I've checked most of your list, it's a new computer so no dust, all fans
work with nothing touching, I haven't tied the thermal paste yet and I have
a PCI exhaust fan on order as well as an 80mm case fan. So fingers crossed
with that lot done I'll be able to put the cover back on.

For an Pentium D system you need these fans:

CPU Fan (every new computer has one of these)
Power Supply Fan (every single computer should have one of these)
GPU Fan (a fan on your graphics card if you have a bit higher
end-256MB, etc. video card.)
80mm case fan

With all these, I got idle temperatures of around 45 degrees, and a
maximum temperature of around 53-55 degrees, and that was with the CPU
fan running at aroun 1900RPM. If I increased the threshold for the
fan, the system would be even cooler. I think you have enough fans,
but you need to reapply thermal paste. Also, was your computer custom-
built by some computer shop, or is it a brand-name computer (Compaq,
HP, Lenovo, Sony, etc.). If its custom-built, it probably needs a new
coat of thermal paste because occasionally, the people who assembled
it get sloppy with it. If its a brand-name computer, it should be
ready out of the box with no problems. Check if there was a recall if
you have a brand-name computer. Also, if you cant fix the problem, if
you have an active warranty, simply back up all your data and return
the computer. They'll either give you your money back OR they'll give
you a new computer.

Hope this helps

By the way, the MAXIMUM allowed temperature for your CPU (if it is
indeed the 2.8GHz Pentium D 820) is 63 degrees celsius. Although the
heat will not fry the processor, it will definetely decrease the
lifetime of the CPU and the fans, it will make the processor slower,
and it will make your computer a lot louder.

Also, visit http://www.heatsink-guide.com for information on
temperatures, thermal paste, and computer cooling.. I got a quote from
the site that might make it seem a bit less serious:

"Note: Pentium 4 and Pentium D temperature specifications indicate the
maximum cover temperature, which is typically lower than the
temperature reported by the internal thermal diode. Therefore, your
system may be running fine even if the reported "CPU temperature" in
the BIOS is higher than the temperature specified here. This does not
mean that you're on the safe side, though. "

Hope this helps

Thanks,

I bought the computer in parts, motherboard/CPU/fan already assembled,
seperate case etc. I've tried applying a new coat of thermal paste and this
has helped a bit but not enough. I'll try the new exhaust fan I've ordered
and if this doen't help I think the case may be the problem not allowing
enough air to be circulated, time for a few extra holes or a different case.

In general a well designed case will run cooler with the cover ON, so
the airflow goes where it should.

Lots of posts on this already...

I would add another 80mm fan if possible, which not only gives you more
air, but some reasonable failure mode if one fan dies. All fans should
be top quality ball bearing type, this is not a good place to save
money. And of course make sure there are no uncovered slots. You want
those cover plates anywhere you don't have a card, for airflow control.

I find that the cases with a fan in the side tend to cool better than
the solid side models, even though I bought the first one for the sexy
neon lights (I give demos and classes, flashy gets attention). If you
have a lot of disks you are putting more heat in, if your case has a
mount point in front of the drives for a fan, it may help.

Your later thought on "new case" may be the solution, but try a few fans
first.

Yes, add some more fans (80mm is nice, but 120mm is nicer if you have
enough room!). BTW, what is your case brand and model? The desk cases
(the horizontal ones with the monitor sitting on the top tend to have
more cooling problems than tower cases if you are using a dual-core
processor). Try and give me a link for a pic of of the case. I have
heard about some Silverstone cases having cooling problems, but not
about other brands. Also, make sure that the ventilation holes on the
back of the case (if there are any) are not clogged with dust and
provide sufficient airflow.
