weird temp reading on AMD athon xp 2400

[dirtfarmer]

i have a little point to bring up, about CPU temp on a AMD athon xp 2400 (2 Ghz), i download SiSoftSandra, and fresh diagnose, speedfan, and motherboard monitor, just to see what heat range is,
i seen to be get confusing high and low temp reading from all of them, went i test it under light and heavy load, and some reading are above the normal for what a AMD athon xp 2400 should be, which is
i recently just install the cpu useing cheap heatsink paste, and wondering about heat on CPU, which the Maximum operating temperature is 85 C

i try testing the differnt program at different time, and one right after another
light load
bios 58 c
sisoft 59 c
speed fan 57 c
fresh 57 c
mother borad 57 c
but then after a bit i retest, and it was not under not must of a load
sisoft when to 95 c
fresh when 89 c
i did not test the other at this time but i reboot, and test temp in BIOSs and it was 57 c
.....................

i let sit for a while, had other thing to do and play a game of HALO, and after i was finsish i test useing the 4 prgram a gain
fresh 81
sisoft 100 c
speed fan 92 c
MBN 5 93 c
now that is weriod, at that temp w you would thing some thing would go very w rong

in wrting this post i stop and test again
sisoft 57 c
speed fan 56 c
mbm5 56 c
fresh 56 c


but i notice even now as im trypeing, temp reading on the ,b,5 that i have runing is rasieing

how question,, are the prgram totla out in left field, or is my cpu really heating up

[saphalline]

You mentioned you just recently installed that CPU. Did you upgrade from a slower one? Did you update the BIOS?

Whenever I see abnormal temps in the BIOS, I think of an update. Afterall, the software you're using is based on the diodes and/or BIOS readings anyway!

[dirtfarmer]

i upgraded from a amd duron 1 Ghz, and i did update BIOs from gigabyte,\ther have a beta for bios, but it look like ther are never going to finish it,, to old a MOBO for them to now any more from 2002

PS

i went from a F4 to F5 on this site http://www.gigabyte.com.tw/Support/Motherboard/BIOS_Model.aspx?ClassValue=Motherboard&ProductID=1313&ProductName=GA-7VTXH+

Was the BIOS reset for the new CPU? What HSF unit did you use? How long ago did you install it?

The temps are definitely high for an AthlonXP 2400+. Something is wrong. We just have to find out what.

[dirtfarmer]

(****)---Was the BIOS reset for the new CPU?

....no, other then install a new BIOS, from gigabyte, i went from a f4 to a f5, i hardly look at bios after, only to see if the bus move from 100 to 133 mhz

(****)--- How long ago did you install it?
..... i just install it a couple day ago, i had it a week a go, but was waiting for arctic silver 5 thermal paste to come but it never did, so i finally install iy useing the paste ther send with the heat sink , cheap white paste



as i was writing this note i was also watching the temp, to what is what, after finsihig this note i reboot to biso and check, it was 57 c and fan speed 6026 to 7031 RPM ( that about all the keep the same on on prgram is the RPM )
sisoft 58 c
speed fan 57 c
MBM5 57 c
fresh 85 c ( higher then the rest for some reason ) ( re tested the other )
sisoft 85 c
speed fan 84 c
MBM5 87 c
rebooted to BIOS,, it was 57 c

but any way my case does not have a fan, but it build for one and my MOBO does have a plug for it, so i have a 80 mm case fan comeing, but more noise i gluess, but a cooler case, gluess it a trade off

just as i was finish up her i just watch MBM5 go from 91 c to 57 c
this is so strange, one would think if the reading are correct, some thing would stop working or burn up

Ok, I see a couple things going on here...

First of all, a new HSF installation with fresh thermal grease will take awhile to reach full effectiveness. Those temps will probably drop 2-5C in the next two weeks from thermal settling alone. Gotta wait for the thermal grease to squish into all the nooks and crannies.

Second of all, the fact that you have no other case cooling is your primary heat problem. I'm sure that the old Duron 1GHz ran just fine without extra cooling, but that's because it's a relatively slow CPU from a different era. The new AthlonXP you bought needs a bit more! You definitely need a few case fans in there for added cooling. You cannot rely on the CPU fan and PSU fan alone - not anymore, not for modern hardware. Until you get more fans for your case, I'd suggest you run the system with the side panel off and a house fan blowing into it. Test your temps after that, and watch them sink like a leaky boat!

Thirdly, the fact that your CPU's fan is running at 6000-7000rpm, well beyond its rated speed, is further evidence that your CPU is overheating. Your mobo is sensing the added heat and is cranking up the CPU fan to try and compensate. But with the dead air inside your case, the heat from the CPU is just being pushed around and recycled. Cool air needs to get in there in order for the CPU HSF to do its job properly.

Let this be a learning experience. Never run a modern system without at least two case fans! My own gaming system has 4, and I'm thinking of adding one or two more.

dirtfarmer rely------yes i have read some where it take a while for the thermal paste to set up, but as soon as i get my Arctic Silver 5 , i plan to change the thermal paste to it, it suppose to be better then the white silicone paste paste that i use and what came with the heatsink, but accord to there web site it take a lot longed to set up (the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability.)(Performance: 3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads when measured with a calibrated thermal diode imbedded in the CPU core.)
we shell see, but then most any thing would be better then the cheap white stuff

dirtfarmer rely------im begining to think i had a problem even with the old duron 1 GHz cpu, as it was reading at 80 c,, when i test it before, when max is at 90 c,

i have a problem with my case, i only have room for a front bottom case fan, it has the hole ther for one, but never was one. no other room for any other, one the max i can have with this case, and my top or cover you would call it it a 3 shape upside down U, or horse shoe shape lol, so no help there

ther is one thing, i do dislike the way the power supply PSU is so close to my CPU fan and heat sink, just barely over 4 CM (1 Inch space beween them, but the olf fan and heatshink was a lot worst, it was a AMD type, big, and ther was even less space beween cpu fan and psu
see picture of old and new heat sink

well you well right about thakng the cover off and puting a house fan, blowing air in to compter, temp drop like a rock
Bios cpu 43 c system 30 fan 6026-7071 RPM
fresh cpu 42 c system 31 c fan 6308 RPM
sisoft cpu 43 c system 30 c fan 6308 RPM
speedfan cpu 42 c system 31 c fan 6308
MBM5 cpu 42 c system 31 c fan 6367

dirtfarmer rely------ yes i agree with that, i have been thinking about that for a while, that why i order a 80 MM case fan, i did notice esp with new athon xp cpu that ther seem to be more heat when i open case and heatsink is very warm to the touch

[dirtfarmer]

picture are worth a thousand word\\pic of old amd heat sink, very close to psu

new heat sink a bit more space from psu, but not over a inch

and the hole for my case fan when i get it

[dirtfarmer]

one thing i did find out, and it was done by a couple people, stateing that the hole reduce air comeing through, was to cut out the the spot where the fan is to be place, to help with air, well, it should work, and from what i can see the hole can reduce the air flow


all so the wire and cable, it a mess in there, should find a way to tire them up so it does not look like some thing the cat drag home

i had look at the round cable, sure look a lot better the the flat one

[Fruss Tray Ted]

What is this pc, an eMachines?

If compatible, I would seriously consider replacing the case with a full sized atx instead of the micro atx your system is 'incarcerated' in right now. That alone will bring temperatures down because the power supply won't be blocking airflow.

[dirtfarmer]

it a custom build case from chips pcmand it a tall one , it has 3 bay for cd rom

[Fruss Tray Ted]

A regular atx case has four 5-1/2 inch drive bays for cdrom's.

The pictures you provided show the power supply on it's side in the way of good airflow in an extremely crucial spot.

That configuration is terrible. Your test results removing the side panel and using a house fan is all the proof you should need. That case design is JUNK!

Notice how the power supply is out of the way of the CPU's heatsink and fan in this pic (http://www.bigbruin.com/reviews/silent2l/images/installed%20large.jpg) as is ALL 3 of my atx cases.

[saphalline]

Ugh! That case is horrible! What sort of AT-to-ATX hack job is that?? The design is reminiscent of the old Pentium II era, and not suited at all for modern systems. I suggest you replace that cr@ppy case with a good one. And use the old one for "aggression therapy". :p :D

[dirtfarmer]

saphalline
you are right it did come from the intel pentuim age, when i first got the case it has a intel celeron slot 1 CPU 433 MHz, of which i burn out trying to over clock

i then got a pentium 2 800 MHz slot one cpu, but had a problem with and repair guy talk me in to get a gigabybe MOBO and a AMD duron 1 GHz cpu, of which i have now replace, with a AMD athlon xp 2400 2 GHz

yes the case, i would say is not build for a amd cpu

i had the compter to 3 differnt repair people over the time ,i had the amd cpu in, and not one mention any thing about the case

just finding out now with new athlon xp cpu installed

so i gluess ther really no need to think of puting a case fan in the old case, you would just get a new one--

ok
question would all case work for any MOBO, and what would be a good one. and would you go for plain jane model, or one with famcy LED light

[Fruss Tray Ted]

Any old atx case should do you just fine.

I don't know what you have available for prices or quality in your area. Cheap ones are noisier usually, because of thin aluminum components and the walls just resonate the sounds of fans within.

What I would look out for first is:
Do NOT buy one with the power and reset switches on the top of the case. Any time something is placed on top, including a hand or elbow, the pc restarts when you least want it to. :o

Front usb or Firewire is nice if your mobo supports it. Front sound, ehh, :rolleyes: not needed.

Other than that, if your current power supply isn't all that good or could use upgrading, get a case with a known good PSU, or get them separately.

Case lighting is personal. Kind of like Christmas lights. You can consult Tim Allen from Home Improvement on the trials and errors of that, or Chevy Chase even,, from National Lampoon's 'Christmas Vacation' (http://www.youtube.com/watch?v=75JGdeM2nAQ&mode=related&search=),,

I prefer mine on a tree. ;)
