1.3ghz Duron on an Abit AT7: 43C idle with a Alpha 8045, does that sound right?

Anyone know of any sensor problems with the AT7 or the Abit Hardware Doctor? It's showing 43C idle on a Duron 1.3ghz. Running an Alpha 8045, ASII, 49cfm YS Tech fan. Wasn't aware of Duron's putting out so much heat. HSF has been taken off/re-applied several times with no reduction in temp (to make sure it wasn't from improper installation). Anyone know what could be causing it, or are those normal temps? Probably looking at something like 20-22 C case.

I have a Duron 1ghz system that runs at about 38c to 41c idle so that sounds about right. I think the durons are still on the .25m process, and thats why they run so darn hot

what is your case temp? I know you said 20-22C, but is that what hte system temp sensors are reading?

Does the AT7 read the internal diode, or does it use a socket-thermistor? 1.3ghz Durons should be "morgan" core durons, so they should have an internal diode.

Of course it is just a "socket thermistor", but I have a 1GHz Morgan at 1.85v 1209MHz. Idle 32c, 41c under full load. 90mm blowhole over the heatsink (golden gate/30cfm fan) two 80mm exhaust.

No, Durons use the 0.18um process. I have a Duron 900 and every piece of diagnostic software have no problem deciding this (hell, even mIRC clients figure it out right) so a Duron 1.3GHz with the newer morgan core should be lower than 0.25um.

Also, how do you know that the motherboard isn't reading the internal temp diode on this Duron??? All Durons at 1GHz or greater have internal temp diodes and all decent new motherboards should be able to read it.

actually, not all 'newer" and decent motherbords read the diode.

In fact, here's a fairly comprehensive list of common consumer boards that do:

Asus A7V333
MSI KT3-and variants
Soltek DRV5 (possibly?)
Various dual boards

Durons run hot compared to Athlon XP's. I had an athlon XP 1800+ that on avrage ran almost the same exact temps as my 1ghz Duron system. Very odd, no matter how many times I applied ASII the durons Idle temp never gets below 38c, the XP usualy stays around 36c.

well, there a couple of factors as to why you can't compare duron to athlon XP temps, including different PCB for slower durons versus AthlonXPs, and slightly different die "size" which can cause variability in socket-thermistor readings.

In addition, the small contact surface of the Duron hurts its cooling, similiar to how it might hurt tbred cooling.

That looks about normal for idling. If you want to lower your temps try WPCREdit and change registry 52 to EB. This not only puts my idle temp at about 29ºC (vs 43ºC), but it also eliminated lock-ups I was having while playing Counter-Strike. Download a CPU load utility and you'll notice that at idle your CPU goes from 20-50% load. After the registry hack the load on the CPU at idle was 5-13% and also it helped the performance when many programs were running at once.

Hey guys, sorry for taking so long to reply to this and letting it drop. I just wanted to say thanks for the replies, I think we got it figured out. This was for a hsf I sold to a guy. I should have thanked you dudes sooner; it's the entire reason I come here.

What I've pretty much figured out:
Durons run hotter than XPs
Smaller contact area means less room to disapate the heat
High case temp (28-30)
Mobo based sensor (not on chip)

With those factors it looks right about where he should be. XPs (for me) have been 10C higher roughly than the case. So if the Duron runs hotter, that should look about right.

Thanks again guys, appreciate it much.
