AMD Athlon XP Thoroughbred Temperatures? (are they low?)

gksam · Post by **gksam** » Mon Mar 17, 2003 5:29 pm

Hello,

I was curious about the new AMD Athlon XP Thoroughbred core chips, so I used them in two systems I have built. They seem to be lower power consumption than the Palominos..(lower voltage and smaller die size I believe).

Anyhow, I built the systems, using a Gigabyte KT400 board (its great, it unlocks the multiplier). The two I got were OEM XP1700+. They seem to be stable at default voltage at XP2000+ levels (not bad for an $85 CDN CPU). Anyhow, the CPU temps seem a little low. They are 31-34oC at idle.. at load they are around 40oC. This is similar to my P4 1.6A overclocked to 2.133 (which is 34oC idle).

I measured the temps of the CPU using Motherboard Monitor. I also got low temps in bios too (in the 30's). So I am somewhat suspicious that this board may report the temperature too low. I have the latest bios as well. The cooler one one of the systems is a Volcano 7 with a Panaflo L1A @ 12V. The other one is a ThermalRight AX-7 with a Panaflo L1A @ 7V.

I have also built 2 more for friends, except based on the XP1800+ retail box CPU with retail HSF. One is going at 2200+, and is in the low 30's as well. The other is going at 2300+ and is also in the low 30's. (both of these are using the same Gigabyte GA7VAX board).

All 4 CPUs are using silver thermal paste (noname kind). These temps seem kind of low. Does anybody else have any experience with the Thoroughbred cores and what kind of temperatures they get?

Cheers

im running:
asus a7n8x
xp 2600+ 333fsb
slk 800 w. 7v panaflo L
thermal compound came with the slk

temps around 40-44C

I've got a pair of Tbreds, a 2400 and a 2100, both running SLK-800's with L1A's at 7v, they both top out at about 42C.

Seems like your temps are right in the ballpark. With the change to .13 micron as well as the added interconnects tbreds are much cooler than Tbirds or Palaminos

Thanks for the replies. Glad to know that my board isn't under reporting anything

Cheers

Don't forget that there are two kinds of Thorougbreds, A's and B's. The A's reduced dies size by a greater percentage than they reduced heat (or something like that). The B's have a die with one more layer and a larger surface area.

I believe that as a result, the B's are easier to cool. For more info on this and how to tell them apart goto http://www.overclockers.com/tips00173/.

Newegg has Athlon xp 2100 oem (tbred revision b) for $86 now, I ordered one and it should arrive sometime this week. My current rig has an Athlon 1800 palomino , alpha pal8045 with panaflo l1a. I have read that the tbred revision b run much cooler, and that the Athlon 2100 can be safely overclocked to a 2400. ...by the by, I motherboard onboard temp sensors are not very accurate, I have one of those LCD temp panels, where you tape a sensor close to the cpu core, it's alot more accurate.

Yeah they do seem very low for Athlon CPU's, I got around 55oC idle for my XP2200+ CPU using Zalman CPNS6000Cu and shot up to about 65oC under load.

What is ambient tempertures?
How is your case cooled?

Wow, that's way high.

I'd double check your thermal grease application, as well as the clip. What fan are you using?

I no longer have this setup, but when I did I think it was the Zalman cooler than anything else, it's not a good performer if you check out the AMD heatsink shootout and with a 5v fan on it, I did not expect much either. From the forums discussion with this exact HS, these kind of tempertures was not too uncommon.

But now I got a P4 1.8A now and achieve much lower tempertures.

The cost of me to get a good HS, such as the SLK-800 cost me about £50+ in the UK. The CPU I had is one of the worst to cool due it's small die area (check recommended CPU). I also had issues with the Asus board which ran the CPU at 1.7v instead of 1.65v which did not help matters much either. There was no way to undervolt it, Asus issue!

I ended deciding to buy a P4 1.8A + motherboard for £120, but I sold my Asus mobo and CPU for £110, so I did not do too bad! I let the new owner who is not concerned about noise have a jet engine.

Best of all my new setup is super quiet now.

I've also got a 2200 XP, with a Thermalright SLK 800 and a Panaflo L1A at 9V (Arctic Silver 3 heatsink compound), and I get idle temps of about 52C. Ambient temp is about 31C. I don't have a whole lot of case airflow, which may be one reason for the higher CPU temp (a Panaflo at 7V at the rear, and a Nexus NX-3000 power supply).

BTW, the CPU temp is the reading from the mobo's external diode, not the core temp reported by the CPU.

I'm not particularly worried about it, but it's another data point.

Edit: I've also got a GeForce Ti 4200 in there, which doesn't help the ambient temperature.

Hello:

I finally got my GC68 heatsinks from SVC today, and on my brandy new Athlon 2100+ Tbred 'B' I'm running 38C CPU and 34C motherboard under load! I'm running the Win2K Folding@Home console. Idle is about 31-32C. Pretty nice for a $5 HS with a fan!

BTW, I had to "lap" the heck out them -- there were very strong grinding marks and they were not all that flat! I used some wet sanding paper on a flat marble block -- 220, then 320, then 400 grit. They are no where near mirror finish, but they are flat and smooth enough to get those low temps.

XP1700+ (T-bred A.. not B). Running overclocked at 2000+. It is 39oC running folding (100% CPU) for 6 days. At idle, it is 31-32oC. The case isn't coold very much. Its closed, and the only other fan is the 7V powersupply (single fan) panaflo fan. Other component in the system is a seagate 80gig. I removed the chipset fan as well. This is using an AX7 heatsink with 7V panaflo on the CPU. Ambient around 21-23oC

Hey maybe it's that tropical weather we have in the UK

, I have almost the same readings as ez2remember!

55c idle, 62c using United Devices, 65c if I use AMD Burn program. Running an Asus A7V333 with XP2000 Palomino, no overclocking, Zalman flower heatsink and Panaflo L with duct (will soon post piccies on separate post). Ambient well I would guess 22-25c, Mobo 31c, Barracuda IV 80Gb 32c, IBM Deskstar 80Gb 34c.

Incidentally, my system works fine & smooth until I hit about 80c when the Asus COP (CPU overheat Protection) kicks in and switches the PC off. Now before anyone thinks I'm mad, this was a one off accidental finding(long story)!

My Tbred 1800+ (running @ 1666mhz -- 166 * 10 @ 1.6v) is usually around 35°C with the zalman 6000cu and the zalman fan at 5v (though it doesn't get any colder when I put it at 12v)

Mirar · Post by **Mirar** » Sun Mar 30, 2003 10:02 am

With my air cooled system I got 37°C idle, 55°C working; with my semi-passively watercooled system I get 40°C idle, 58°C working. I don't seem to get any overheat effects until I reach maybe 70°C, but I think it's the Radeon on the same water that dies then. (Idle temperatures with NB shutdown aka VCool.)

It's important to tell us what motherboard you are using... some motherboards read high, some low. I wish all of them would just display the internal diode temp, so I could tell what the REAL core temperature was...

Anyway, I have a T-Bred B 1700+ (DLT3C version, has a default 1.5vcore) running at 1870 (170x11) with default voltage on an Abit NF7-S. I've read that this board either messes up the core temps or gets them right, reading them quite a bit higher than most other boards. With a SLK-800 and a panaflo M1A at 12v (don't kill me), I'm running idle at 40C with 27C case, and roughly 21C ambient temp. Seems really low, compared to other temps I've read. Those were all heavily OC'ed, though, with like 1.85 vcore or something insane like that.

actually those temps were with the panaflo M.. 44-45 under load

you might have the revision A of the chip.. they are supposed to run a bit hotter.

when i run with the L my idle temps at 44 and about 50 under stress

nutball · Post by **nutball** » Mon Apr 14, 2003 11:30 pm

My 2000XP+ runs at 50 degrees idle, sometimes up to 64 under load. This is the Zalman copper flower HSF thingy with the fan turned to its slowest setting, on an MSI K7N420 board.

halcyon · Post by **halcyon** » Mon Apr 21, 2003 10:37 am

My case temp is now at 37 degrees and XP2100+ (thoroughbred, 1,625V) is at 47 degrees centigrade.

When my case temp ups, the highest I usually get with the CPU is c. 62 degrees Celsius.

My mobo is A7N8X and I use MBM 5.3.00 to measure temps.

regards,
Halcyon

i got palomino 1700+ undervolted @ 1.6 V, glacialtech igloo 2320. under load 48-50 degrees celsius. i'm thinking about getting the silent breeze igloo that should be more effective and 6 db more quieter. igloo 2320 must be the biggest noise source in my computer right now along with the antec trueblue 480 w.
