Yeah I saw you had an Antec 900 and should have excellent
idle temperatures unless you're majorly ovrclocking the idle speed or
the BIOS is overvolting Vcore or something.
Oh another possibility -- check to see if you're using some kind of
automatic thermal management on the CPU fan RPM. It's possible
the CPU fan isn't spinning at full speed (or at all!). I'd always set the BIOS
or fan control program to run the CPU fan at at least 2200 RPM if not full
speed of whatever it can do that's higher.
Unfortunately there's only two ways to tell what the best thickness and application
technique of thermal paste is:
a) Try it, check your load temperatures, take it all apart, retry with a different
thickness, and keep doing that until you get the low temperature you expect.
b) You can sort of tell how much thermal paste is right by looking at the
imprint shape and thickness in the thermal paste residue left over after you
take the heatsink off the CPU.
Basically ideally you want to see a thick 'crater wall' of paste around PAST the
edge of the area where the border of the CPU IHS prints on the heatsink
assuming the heatsink is bigger than the CPU IHS size.
Then in the middle of the HS where the CPU IHS was in contact you want
to see a thinner "pressed down" layer of paste where you can tell that
it was actually pressed and deformed by physical contact between the
CPU IHS and the HS. Like leaving a foot print in soft mud. But if the
mud is too shallow (the paste is too thin), you'll see a print of your
heel and toe but the arch of your foot won't leave as much or at all of
a print in the mud because that's higher than the thickness of the mud where
it curves up and so it doesn't really disturb / imprint the mud where it's
too high in the tread / arch to make contact.
So if you first apply a really thin layer of paste, assemble, tighten, then remove
the HS without ever firing up the PC, you'll see that it only might make contact
in a few spots and not at all in a few other spots unless it's all dead flat and
totally in contact (which would be GOOD but doesn't always happen!).
Then if you put the paste on thicker it'll spread out more and more and more
parts of the CPU IHS and HS will imprint to each other in the paste and then
it'll be as thick as you want it.
That's probably one advantage of using the method of application where you
apply a very thick 'line' of paste across the IHS top and then just let the
CPU to IHS pressure spread it out across the space between them.
Only problem is if you have any really thick gaps in places between the
CPU IHS and HS in which case it'll be unlikely to even go into or past those
areas of relative warpage. But in those cases you really pretty much need
to sand them flatter for best results.
Anyway try putting them together a few times, look at the imprints, and then
you'll have a better idea of if they can make good contact with thin paste
or not.
Good luck.

QuixoticOne thanks for the major input I am going to remove the HSF today and check it but I am pretty sure it is not warped at all....I used a CC to apply the paste is there a way to tell the right thickness at all? Also don't know if I am quite ready to do the sanding thing that is a little much for now....the antec nine hundred has soo many fans that is one reason I assumed I would have lower temps. Unfortunatly I dont think I was getting an accuarte reading w/ the stock HSF but when I used speedfan the overall temps I remember were lower I just was not reading it right until after I made the change ...I have always used speedfan also
Couple hours and I am off work and will re-apply the paste .....whole situation just sucks I guess i am just not confident I am applying the paste at the right thickness although I know there should not be much
