Thanks for all the replies. I checked all the hardware, the Fans are working, there's enough thermal paste applied... I just don't get that windows keeps my CPU cooler (about 10°) (even when idle).. I've tried recompiling the kernel with ACPI support, and DO_CPU_IDLE Calls, no result... I just don't get it...:-(

Hello All, Well I am an Athlon master, I've been over clocking and modifying Athlons for a very long time, and I have about 5 box's running Athlon processors... Now they all run relatively hot about 52@idle and 62@Full it the normal temp range for me. but there is an outliner in my ranks... it's an MSI Board, K7T Turbo-R Limited Edition, there is nothing special about this board the only thing that is different is award bios and some more options you can mess with, and this really cool red pcb board. And that sucker runs at 62@idle and 75@full, and that it way too high for some ppl, but so far it's the most stable athlon board Ive seen, and it works with sblive, something that abit and asus have problems with, I really don't trust abit now... cause it melted on me, I had this abit KA7-100, that just melted on me... literally... the capacitors blew off... it was 750 Classic Athlon @ 925, with a good peltier. It was my test board and my bios mess around board.... Now back to my point every kind of board shows different kind of temperatures... Here are my Test Boards..... Abit KT7E-Raid MSI K7T Turbo-R Limited 1.2 Ghz (266) Boxed 1.2 Ghz (266) Boxed TNT2 M64 32 MB TNT2 M64 32 MB Sblive Mp3+ Sblive Mp3+ 20.4 Gig Maxtor 20.4 Gig Maxtor Intel Pro NIC 3com 3c905c-TX NIC Win2k & SuSE Linux 6.4 Win2k & SusE Linux 6.4 Stock Athlon Fan Stock Athlon Fan Win2k 53 @ Idle Win2k 62 @ Idle Linux 57 @ Idle Linux 65 @ Idle Win2k 62 @ full win2k 75 @ full Linux 70 @ full Linux 76 @ full So as you can see there is a difference between the temps of these motherboards, we all can see that the MSi Runs very hot... I think it's due to the core voltage on default it being a litle too high... now I've used the bios to monitor the temps and the digitaldoc 5 tool to monitor the heatsink temps... I think MSi runs hotter, or seems to run hotter, because the cpu temp probe is touching the underside of the cpu in the Zif socket... here is the technical drawing of it in text. ;) ####################### ####################### <- Fan %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% <- Heatsink %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% %% ^^%%%%%%%%%%%%%%%%%%%%% <- Bottom of Heatsink *******^^^^^^^^******** <- Copper Shim and Core with Copper Goop $$$$$$$$$$$$$$$$$$$$$$$ <- CPU Boad @!@!@!@!@!@!@!@!@!@!@!@ <- Zif Socket and Heat Sensor It's touching CPU On the abit and almost every other board the heat sensor is not touching the back of the cpu, and thus kinda measures the ambient temp of the air, and not the actual cpu. It would be really cool if AMD finally got around to putting heat sensors inside the cpu like Intel Does... sure would make my job more fun... and accurate. So like I said your Athlon is not hot until it's around 85 Celsius, and then I would think about getting a new mobo or a better HSF... If you think your cpu runs too hot, I would suggest lovering your core temp and getting some better HSF and if that does not help and you are not a faint hearted person you can try using a peltier to cool it down, I would suggest to get an alpha cooler for your amd... and if that does not cool you... well then peltier all the way... and maybe a delta fan on that HSF... but it might be your case... poor ventilation is the key to all heat problems with athlons... If you have any questions please direct them to me via email and phone or voice.... I can also be found on rshakin @ toc.oscar.aol.com or as many ppl refer it to as aim... I wish you luck with your board and may it stay stable for a long time... long live Athlons --Roman PS: Yeah I know I do have too much time on my hands... On Tue, Aug 14, 2001, Dave Smith wrote:

Athlon 4 does contain an on-CPU thermister on the models I've seen. AFAIK, lm_sensors and the likes don't support this yet. regards, Dave. -- | Dave Jones. http://www.suse.de/~davej | SuSE Labs
Hey all, Just a quickie - On the old AMD thread of things: I have an AMD Athlon 1GHz on a K7VZA mobo. This is linux related as I run linux on that machine - but is more of a hardware question. If the computer has been on for any length of time, there is about a 90% chance the following will happen when I turn the machine off and on again: The machine doesn't "turn on" - We have power, but it doesn't get to the Graphics card init, and the processor QUICKLY heats up![I turn it off in a matter of seconds, and the heatsink is difficult to hold due to the temp]. If I remove the heatsink and cool it down with a desk fan and then refit it, then about 80% of the time it will work straight away when I turn the machine on... And then if I go into BIOS temperature readings, the temperature rapidly decreases as the heatsink does its job... it has been as high as 70 degrees!!! Otherwise the CPU runs at about 34 deg Celcius after running Linux or Windows for hours on end. Oh, the case is open and has a desk fan blowing into it until I get to the shop for a few case fans! "System Temperature" stays at around 25% celcius at the moment. And ideas? Flaky mobo or procesor maybe? I hope not as I can't really afford to shell out on a new one!!! If needs must though....

Hello All, I get a number of emails asking "My Duron/T-Bird runs at 45-50-55-60-65 C; is this too hot?" In my faq, anything over ambient is too hot, a great goal but not realistic for air cooling. For an answer, I took a look at some AMD specs to see what AMD recommends. I'm going to look at two areas: AMD's recommended temps and the difference between cooling Durons and T-Birds. AMD's absolute temp maximum is 90 C up to 1000 MHz and 95 C over that. Anyone even close to these temps is one step away from a toasted CPU. AMD's specs contained in "AMD Thermal, Mechanical, and Chassis Cooling Design Guide" (p. 13, Publication # 23794 Rev: B Issue Date: October 2000) gives the following guidelines: CPU up to 48 watts: C/W of .55 CPU up to 55 watts: C/W of .41 CPU up to 70 watts: C/W of .32 C/W means that for every watt the CPU radiates, the heatsink is supposed to cool the core by C/W x watts plus ambient temp. AMD specs system temp at 45 C, which is on the warm side. What all this means when you run the numbers is the following: CPU up to 48 watts: 26.4* + 45 = 71.4 C CPU up to 55 watts: 22.6 + 45 = 67.6 C CPU up to 70 watts: 22.4 + 45 = 67.4 C So if you just adhere to AMD's spec, anything over 67 C is not recommended. Hopefully you do better than 45 C case temp, so you should knock at least 10 and better yet 15 C off the 45; this gives you something like 50 C, assuming a 30 C case temp. That's about the upper end of "acceptable" from my perspective. It's no surprise that we are seeing a lot of heatsinks coming with Delta 38s - how else can they deliver cooling temps that we consider acceptable with older heatsink designs? This new crop of "screamers" is pushing C/Ws into the 0.25 range; this means, with a case temp of 30 C, CPU temps of 47.5 C at 70 watts is achievable. But if you are really concerned about your core temp and your case temp, I would suggest you get a 50+ watt peltier and not worry about your processor being too hot anymore.... and worry about your processor being too cold... :) I happen to have a MSi K7T Turbo-R Limited Edition, and as most of the overclocking community knows that this motherboard is a power hog. This is it's current output... 8/21/2001 | 1:46:16 PM | 1207 MHz | 72° C | 30° C This is using a 1.2 ThunderBird 266FSB Boxed CPU and Stock Cooling... Yeah not too fun... I am forced to use peltiers on this board... because it's very hot... I've used this CPU in Abit Kt7-Raid and had Temps at 55@idle and 66@full load, and on this board I have this temp range 62@idle and 75+80@ full on a hot day, with no ac running... Right now it's at 67, while I am writing this and working in Gimp and Running X and Bunch of other Stuff... but not at full load. And it's stable as a rock... I think it's all depends on the motherboard you are using and how close the temp probe to the core of the cpu... i have one of those flat ones and It's right under the cpu... # # # # # # # # # # # # # # # # # # # # # # # # ####################### <--- Heatsink *******^^^^^^^^******** <--- Copper Shim and Thermal Tape with CPU Core !@!@!@!@!@!@!@!@!@!@!@! <--- Socket A, and Cpu Sensor As you can see from my crappy asci art... yeah I know I am not good at it I get more accurate temp readings by having the sensor touch the back of the cpu core... and thats maybe why it's shows it at being hot... I also have a Digital Doc 5 that monitors my Case Temp and My Heatsink Temp... And it says that the Temp on the CPU heatsink is 43C@ Full and 35C@Idle... So for everyone who thinks that your CPU is running too hot, it's probably is running too hot... So if you are really concerned about it... put a Peltier on it and you won't have to worry about it being too hot... but you might have to worry about it being too cold... :) If you have any questions feel free to email to me.... or call or page... and even use snailmail if you really like to :) --Roman PS: If anyone has an old Abit KA7-100 and still has all the manuals and a box... would you please email me... abit won't accept my stuff withought the box... If you really want to know what happened to it... I melted the capacitors and they are nice and brown looking... I think I am one of the 5 people who did it... I think I deserve some kind of a prize for that... On Tue, Aug 21, 2001, The Purple Tiger wrote:
