High temps on an A7N8X

Hey hope some might be able to answer this. I just built up a buddys computer
around the A7N8X. The CPU is a 1600+, when running idal Motherboard Monitor
reports the CPU Diode as 42C, and the CPU Socket at 34C. When I run Prime95's
torure test, the Socket temp will only jump a little maybe 3-5 degrees however
the Diode shoots up to 70C in almost no time. I'm unfamiler with the actual
temp these chips are supposd to run with the diode since this tech is pretty
new to me (old hand at this but I've only built a few boards that have the
diode).

The parts are all comming off of an older build fo his (old mainboard went
belly up) so I'm thinking that may be a part of the problem, the CPU
heatsink/fan I belive is a coolmaster, at least thats what the sticker says on
the fan. I noticed when cleaning out the case that the dust factor was HUGE and
the fan on his video card had gotten jammed up (presummidly from the dusk) so
could this be a factor maybe with the heatsink fan not running well? When I
transfered all the parts over I made sure to wipe off the older arctic silver
and apply a new thin coat of it. Right now everthing is running smooth, just
the Prime95 test peaking the temps like that has me a bit concerned.

Thanks any who can answer this

70C for a 1600+ ? yikes! Sounds like the HS/fan is not installed correctly (on backwards?) or the fan isn't moving any
air. Might want to check out the install part here just to make sure it's on right, http://tinyurl.com/3ue5

Wish that was the case, the damn thing fits on so tight when its properaly
mounted that if it were reversed I wouldnt be able to latch it. The fan is
moving some air but its spinning with a high pich, higher than I"m used to
hearing. Also the 70C is diode, not socket temp, which is why I'm wondering
just how high the diode temp can reach safely.

85C is the max die temp rating on the XP chips.
Could it be the board just isn't reading the temp correctly? (Does the HS get hot to the touch?)

My Barton (@2200Mhz) was hitting 64C so I re-did the paste (4 more times), on 2nd try it went up to 69C, my last try I
did something right cause now it runs at about 55C max. (die temps).

Huh ok I'll see about reseating and redoing the artic silver. May also try and
convince my friend to get a new heatsink/fan, since this one is a royal pain to
get off the board.
 
I find old cases have poor air exchange rate for the newer CPUs. You can use
as big of heatsink fan on the cpu as you want, but it will get hot if your
psu/case fans are not pulling in cool air. I like the new boxes with the
duct port on the side and the exhaust fan out the back. It keeps things
really cool.

Reminds me of the time when the psu fan stopped on a dual Pentium box. The
case got hot as hell and the unit was unstable. When I removed the cover,
hot air rushed out like opening a hot oven door and it smelled like hot
circuit boards. A now psu cured it. If that happened on a fast athlon, it's
a melt down for sure. Extra fans are nice!
