cpu temperature

[Speed55]

Not sure if this is an issue with bios

Running a p5n-d asus board.

Bios cpu temp is read 55*c. First it was 46*c which i thought was too high, so i removed the original thermal paste, and applied arctic silver.

Real temp is giving me a reading of 34*c and 26*c.

Is my bios screwed up or is realtemp?

edit* just installed speed fan and it's also reading 34*c and 26*c

I did upgrade from an e6400 to an e8400 so i wonder if that has anything to do with it?

BIOS is reading thermal diode temps which can be off up to 10 degrees. Realtemp reads DTS which is more accurate. Also note that thermal paste has to "cure" before it reaches full heat transfer. Depends on your usage, this can take anywhere between a day and a week.

ok thanks.

i'll keep an eye on the bios temps for the next week, also double check that the pins on the heatsink are in all the way, which i'm positive they are, but.. ehh might as well be double sure.

And Arctic Silver works better with a really fine surface. I took my heatsink and a really good lapping kit and about ten hours to work it down to a polished surface but then the heatsink had arrived with some major grooves in the surface (thanks Thermaltake). Once I was finished working it with ten micron paper (the last of a dozen sheets in the lapping kit) the final surface was a copper mirror and properly following Arctic Silvers instructions I thoroughly covered the surface with Arctic Silver and then removed it again with a coffee filter. The result was a surface that was copper with a silver sheen to it.

The final quantity of Arctic Silver was about 1/2 of a BB worth of material but of course that varies by processor. The result was a substantial decrease in temperatures from the stock heatsink. It literally takes about ayear for the Arctic Silver material to "cure" through thermal cycles and in the end if you did everything right the temperatures will drop even more.
