my cpu is overheating when under full load its hitting 80 degrees then BSOD
and shut down. thats with case fans on. i'm using a zalman flower heatsink
and fan. should i get a new hsf? or is it the seating of the zalman?

i'm never quite sure how much artic silver to use, i use a minimal ammount
and spread is thinly over the core. is that right? i saw a vid on toms
hardware guide where they lamped loads of thermal paste on, could that be my
problem? not enough paste?

current temps (idle) according to asusprobe:
cpu 51
mb 31


any advice? thanks

Your temp should not rise that much under load - your zalman HS is
obviously not in proper contact with the CPU core .. check you put it on
the right way round (there are two options - only one works). Lack of (a
lot of) thermal paste should not make that much difference - too much is
just as bad as too little. About a matchhead's worth, spread around. No
more than a small pea, or it'll get everywhere.

51c is also a bit hot for idle, but even so it should not rise 30c from
idle to full load unless the thermal contact is cr&p. Zalman Flowers are
not wonderful HS, temperature reduction wise, but they are not THAT bad!

I don't see anything obviously wrong.

I use a different technique with grease -- squeeze out a
small dab placed centrally. That way I avoid air bubbles,
but it does take some care to squeeze parallel. Many people
report success with the thin film technique. In any case,
the heatsink should slide heavily, not scrape or be frozen
(which would indicate edge contact).

One question: How quick does it overheat? Seconds indicates
poor heatsink contact or a broken heatsink. Minutes indicates
a broken/blocked HS fan. 15+ minutes usually indicates poor
case airflow (blocked vents, external recirc, fans fighting).
Time is controlled by the thermal mass.

I'm guessing by the low MB temp that the overheat happens
fairly quickly. Check that the heatsink isn't cocked on
installation (some can be fitted the wrong way end-for-end)
and the that heatsink isn't cracked/delaminating.

its over heating in seconds... so when you say it may be on the wrong way i
turn it 180 degrees?

thanks

Essentially, yes.

Some heatsinks have a step on the base which will indicate
the proper direction of installation (if the heatsink hasn't
been disasssembled).

The real problem is that while CPU die-back is centered in
the chip carrier, it is _offcenter_ about 5mm assembled in
the ZIF socket. Heatsink mfrs know all about this, and design
clamps to provide offcenter pressure directly over the die.

The clamps are then asymmetric, and must be installed
in the correct direction. If not, the pressure point is
~10 mm offset, and the HS may lift and make edge contact,
particularly with some of the smaller die-backs.

True, but the much worse problem is if the HS 'step' is on 180 degrees
wrong, when you are guaranteed to get only glancing contact between the
HS and the chip.

A definite risk, depending on the thickness of the chip
carrier and ZIF mechanism. A step may not be necessary.

As always, you have to check carefully.

If the heatsink is as flat as it should be it should squeeze almost
all of the thermal paste out and make nearly direct contact with the
chip.

AMD has specifications for required force between the heatsink and the
chip. Check their site to see if your heatsink is AMD approved and
consider some alternatives that are bigger or have larger fans.

thanks to all who replied. i've reseated the processor and cleared all the
dust out of the case with compressed air. i used more arctic silver than i
usually do as when i removed the hsf the cpu had none left on it which was
worrying. now running, without the hairdryer noisey case fan on 100% load at
47 degrees after about 5 mins. usually would have hit 70 with the case fan
after about a minute so it looks like problem solved!

thanks again
