In-Socket CPU Temp. Compensation?

[WillysNut]

After reading some of the articles regarding MBM4 and AMD mobo's w/ in-socket temp probes...I'm a little confused as to how much I should be compensating for the in-socket temps.

The articles seemed to say that the topside CPU temps (temp of the core touching the heatsink) when measured w/ a drilled probe were on average 5-10C higher than the bottom-side temp (in-socket temp).

I'm new to AMD chips so I made sure I pulled up the probe (KT7A Raid) so it would contact the bottom of the chip. I added a tiny dab of AS2 to assure proper heat transfer. After about an hour of Folding@Home (I know...not the highest utilization but...) Via HW Monitor v2.04 showsa CPU temp of 43c. That has to be low...I'm currently adding 5c to MBM4 and running 48c load. Sound better? I'm running a Duron 750 @ 1000 ([email protected]) with a CAK38 and AS2 for cooling...along w/ really good case ventilation. Ambient temp is 23-24c.

Any input? Can people w/ similar setups post their temps (along w/ processor, multiplier, volts, etc) Tx

If you look at the purely mathematical model for the Duron at 1000 @ 1.85V and CAK-38, for an ambient of 24C, the perfect result would be a temp of 40C. If you did a good mounting job, 43C is a very realistic temperature. The only thing for sure with in-socket thermistors is they may vary from one board to the next and the temperature you get from them may vary from the actual temperature measured with a drilled HSF using an accurate thermocouple. Mine is off by only a scant .5C once transition from cold to hot has stabilized. During transition, it is off by as much as 2.5C.

Many thanks Hoot! I thought this post was lost for a minute
