2500+ running cooler than 1700+ with a lot more voltage?

[Calcu]

I just switched to a 2500+ from a 1700+ and noticed at the same clock speed, 2.45GHz and with a lot more voltage(1700+ was at 1.75v and 2500+ is at 1.95v), the 2500+ idles about 5C cooler and at full load about 5C also. Nothing else in the system has changed and the sensor is touching the bottom of the CPU just like I had it on the 1700+. Has anyone else experienced this? I'm not complaining or anything, but I thought the Bartons normally run hotter and the tBred Bs but I guess not in my case :D

my 1700+ ran alot hotter then my 2100+ also..

The barton has a bigger core, so that might explain it.

Maybe its true but I suggest you take this with a grain of salt. Mobo's temp sensors always report false temps.

Maybe you just got better contact with the die this time around on your hs.

isn't the die of the barton a little bigger?
the surface area itself does make a difference considering the barton consumes about the same amount of power
some tests are needed there

I have a new AXQEA on a KT400 board (no 200+ FSB) and these new steppings (AXQDA and AXQEA) seem to be really mature. Plus I agree that the core is much bigger that a T-Bred so you are getting better contact to your HSF....

Even though the Barton has a bigger core, it has more cache, double the L2 cache at full speed therefore it would still create equal to thoroughbred if not more heat.

The updated version of my heat dissipation article will show the diffrerence between the two cores when its done.

Those 1700's run damn hot. The 0319 that I got a couple weeks back ran extremely hot in my prommy. In fact, at startup after leaving it for a day the prom temp would run up to 40°C and shutdown.

My XP2500 barton runs at least 3° or 4°C cooler at same voltage and speed. After leaving the prom off for a few days, at startup the evap temp only reached about 35°C before it starts to chill and the temps drop.. It's no myth! It Definitely runs COOLER>.
:D

I'm glad to see someone else noticed this also but the weird thing is on mine is that with about .2v more, the Barton still runs cooler. But oh well,

My 2500+ Barton runs 3-4°C cooler than the 0319 1700+. Odd as the 0319 seems to me to be a Barton with 256K L2.
