All AMD K5, K6, Cyrix 6x86, 6x86L, 6x86MX should operate at 70C maximum, 60C for extended CPU life. Operating at excessive temperatures may cause CPU failures, so be careful. I found this at http://www.cpu.simplenet.com/heat.htm

TO Brad Probst: Dude I have my AMD K6-2 475 running at 87 F If your 550 Is At 143 YOUR WAY TOOOO HHHHOOOOOOTTTTTT!!!! Go to your local Computer parts supply store AND GET a BIGGER!! Heat Sink With A fan! = ) The one I have is 3inches wide and 3inches long, And 1 1/4 inehes high!!! Very Cool!! CYA L8R

Well first with my Athlon 600, it kept on freezing up on hot and humid days. I had no system fan other than the cpu fan. I put a system fan but it was in the fount of the case and the way the stupid mini case atx mother boards are designed the video card and the power supply block just bout all the air flow to the processesor. So I did my own thing with 3 diffrent system fans. I tapped to of them togeather and mounted them at about a 45 degree angle comming down from my power supply and leaning on the top of my modem (the card next to my AGP). That dropped the temp of my cpu about 10 degrees F, from about 105 to 95. Then I put a bigger system fan mounted on the other side facing my processor. That dropped the temp another 10 degrees. So with my Athlon 600, I am getting it at 84-85 degrees F. That is pretty damn good if I do say so myself. I also have my case off, it works better that way casue it works as a big exaust. With the case on, all that hot air gets trapped in, sure u can add exsust fans, but the case off is just better I think. (I would rather use the extra fans for cooling)

I just got my new K6-2 450. with just bios running (no hard drive hooked up) it sits at 140 deg F. Is this bad? Or does Windows manage CPU temp? (by raising fan RPM?) I am new to the temp thing, and this is my first attept at building my own computer.

I am running a amd athlon 750 at 1000mhz, with a dual fan and never get above 90 deg f. i can run even faster my chip stays cool, just i get fault errors with windows.

I'm new to all this. Does ambient room temperature also affect the temp of the cpu?

I think if your cpu is running over 120 deg Celcius you will have your processor for a very short time and maybe the motherboard too. I think any temp under 110 deg Celcius is good. My K62-450 runs from 25 to 32 deg farenheit thanks to Rain 1.0 very interesting program to keep your processor cool. It is free at zdnet.com, do a search in the downloads section.

Software that can help cool your processor? I hope you aren't betting the farm on that one friend. It sounds to me like that software is just making you either underclock your proc or its just straight out making your CMOS lie about the temp. I just can't conceivably think of ANY software program that could help cool the proc without underclocking it. -DRG-

ok guys seems you know pretty little RAIN is a cooling software using socalled HLT commands (implemented in NT4 - probably in win2k too) but windows9x (and ME) doesnt use them these commands turn off parts of your cpu that are currently not in use so theres no lowering of performance! but if you really want to cool a system you need to do that using fans (as gaming often causes 100% cpu usage and then RAIN wont cool anything) - first take a closer look at your case there must be a way through for the air - get a big heatsink for your socket or slot cpu (dont save money here) - manage that theres no device (card / drive) positioned near the fan - if your case is usually closed then buy a system fan blowing the hot steam OUT of your case (never blow air inside - online if you got another fan blowing it out somewhere else..) the fans should be designed to cool your special cpu - cpu fan: ~4500-5000 RPM (or better) - system fan: at least 2000 RPM i prefer cpu coolers like the GOLDEN ORB (they look damned good! ;) if your system is a high-class pc (above 1GHz or dual cpu) or a server thingie get it watercooling (not intended for home use - just too expensive) my sys... AMD Athlon socketA 1GHz 256megs PC133 60gig RAID array geforce2mx ddr ...reports (BIOS and VIAhwm): CPU: 43-55° C SYSTEM: 25-27° C (using 2 fans only - cpu and sys) btw high ambient temp. increases your system's temp. dramatically.. i haven't tested this yet but i'd never try above 26° C in your room... cause the heatsink will then have to cool your system with that warm air.. not fine.. greetx gizmo

I have Athlon 750Mhz "Socket A" CPU and it Runs At 58->61 degrees Celcius Can Any One tell me the Ideal Temprature for this Proccesor the ambient temp is about 25 degrees C Also the CPU fan Runs At 5000 Rpm Thanks.

..i haven't found any info on ideal temps yet but i think a new cpu above 600MHz will surely have about 50° C in standard working conditions if you get somethink above 60°C you should asap change your cooler or try to lower temp. by another fan hearsay: 70°C = max never compare k7 (athlon) series with a k6 k6/2 k6/2cxt k6/3 or sth similiar athlons always produce more heat if you got a k6 series cpu try keeping it under 50°C (my personal opinion - once had a k6/2cxt 300 @333overclocked w/ a huge socket7 cooler and there was nothing above 45°C) does anyone know about a newer RAIN release (>1.0) supporting athlon cpus ???

I'm trying to run a 450 Pentium II with a standard heatsink with cpu fan, a drive slot fan and a large fan blowing out on the bottom of the tower. Still getting temps in excess of 170 degrees F. Do you think this is a motherboard problem??? My original Celeron 300 ran hot as well.

you should place your system fan somewhere at the top as heat moves up! sorry - dont know exactly what °F is.. (°C+100 ???) but check whats positioned near your cpu..

Thanks For the info Gizmo.. I ran the PC with the Cabinet Open And it ran at 48 C -> 51 C . I suppose that is Okay Temperature. And I Feel a Cabinet Fan Should Help me. Ambient temp 26 C .. And The Ceiling (Room) Fan On :-)

I took the org. tape off the back of my cpu and put cooling compond on it with org.fan AMD750-1000MHz 35deg.C
