Tbred vs Pally Temperatures?

[KIAman]

I have read numerous threads regarding the tbred and how they are so much cooler. I just dont get it, I have tested my 1700+ pally and tbred over and over again with my slk-800 and the pally is consistently 5c lower than the tbred (tbred rev A).
I tested at default speeds and speed and even with same overclocks.
Can people do me a favor and report

1. Which athlon core you've got and type of cooler.
2. Default and current speeds.
3. Current idle/load temps that are shown for cpu and motherboard.
4. Motherboard brand and type and whether it reads from external thermister or internal diode.

With some consistent information, this would finally be cleared up. Thanks for the help.

1. Tbred A , slk-800 84 cfm fan
2. 1400mhz, 2000mhz
3. 49c/55c, 26c/28c
4. Epox 8k3a, internal diode

If you're comparing a 1400MHz Palimino to a 2000MHz TBred, then that is your answer. Just because it is manufactured on a 130nm process doesn't make the TBred cooler at nearly a 50% increase in clockspeed. Plus, the TBred-B is much better in this respect.

I cant really compare temps for you, but I ran my Pally at 1600mhz, 7.25v. Idle temp was 40 to 41 C. I'm running a 1800+ T-Bred(1.675v) on the same bored but 300mhz higher getting the same exact temps, but load temps never pass 46 to 47 C with the T-Bred. Pally got to 48 or 49 c on average. I use an AX-7 and 40cfm sunon in an antec 1030B. The biggest thing that gave me problems temp wise were those stupid pads included on every Athlon XP now, they raise temps pretty bad, for me anyway. T-Breds DO run hotter though, this has already been established by many, there is not enough surface area to keep the chip as cool as an XP. I don't have a bored that reads accurate temps (epox a-holes screwed with the diode reading ability on their 8RDA boards), chances are mine are even higher and I'm having no problems, your temps are fine for sure.

If you read my first post, I stated that I compared the pally with the tbred at the same speeds. I compared at default both running at 1400mhz all the way up to 1826mhz. My pally at 1826mhz would be 41c/44c while the tbred at 1826mhz is 45c/49c.

BD231 so from your own experience your tbred is actually cooler than your pally? That is what I am talking about. My pally is cooler than my tbred. People all over are excited how nice and cool their tbreds are when in actuality (personally) it is not true. Maybe it is just my own chip.
Oh and the pads, you mean the 4 pads on the corners of the cpu? Arent those to protect the cpu core? Or does it matter?

i had a pally 1700 in a K7S5A that ran at 117F idle, i then replaced it w/ an 1800 tbred which ran at 96F idle, quite a bit difference. Both on same board same cooling.

There's no real way to tell if my chip is running cooler since the 8RDA I'm using dose not report temps correctly. I talked to an epox tech and he said to add 10c to 15c to the temp reported on my 8RDA BIOS, so I'm getting the same temps as you are for the most part. Chances are not even your bored is reporting correct temps so there's a huge margin of error between our boards. Your probably giving that T-Bred to much juice or something because your cooling solution is quite a bit beefier than mine, default voltage for a 1700+ is 1.50v. A user error sounds like the problem .

a commmon misnomer is that because the tbred gives off less heat it will be cooler. that not neccesarily true.

the size differences of the cores make the palimino much easier cool since it bigger (almost 1.5x) therefore a tbred might put out less heat but it much harder to cool because of it small die and requires a much better cooling solution....
