Xp-CPU Temp ???

[PPAALL]

Hi;
Running an amd-xp 1600 cpu.In the Ami- bios diagnostic I find the following readings:
cpu temp:53 C / 127 F
Sys temp:27 C / 80 F
But when I check that with Sys Sandra I get the following readings:
cpu temp : 28 C / 82 F
Sys temp : 53 C / 127 F
MB temp : 14 C / 57 F
Please advise which readings to beleive ?
Any reliable temperature monitoring utility if any which can be downloaded?
thanks

If you see CPU temps much over 65 C Then your toooooo hot, does your Bios report temps? as far as software D/L for temp. measuring? IMHO I think there about as good as using Kerosene to get rid of hemeroids.How many fans do you have and what type of Heatsink? But if you rely on D/L you could try this,http://mbm.livewiredev.com/
try this again

Sandra is just reversing your cpu and system temps...it is choosing the wrong thermistor reading...

CPU temps vary greatly depending on what kind of heatsink/fan you use and what kind of airflow you have in your case...

I have an XP1600, overclocked to 1506mhz, with the core voltage set .025V higher than stock and my temps, under load, have been as high as 45C. However, I have a huge heatsink with a 5000rpm fan, 4 case fans, and rounded IDE cables.

As Yoda suggests, MBM is an excellent program for software monitoring, much better than what I got with my board.

You're ok with 53C, but it could be lower...how warm is the room the computer is in? That has a huge effect on cpu temperature. What kind of hs/fan are you using, did you use thermal grease/pad? Are you sure the heatsink is flush with the cpu die (it's gotta be almost perfect already, cause otherwise the chip would cook) it helps to put the heatsink on before you put the mobo in the case...

Hi Yoda & Hiredgoonz;
The xp was bought in the retail package & the heat sink +fan came out of it from AMD I suppose . But I have my doubts -- that a company like AMD will ship that expensive cpu with that noisy fan+heatsink.Well it really sounds loud at 5500 rpm's.
Well Yoda I do have MBM 5 & supposedly running but I can find anything in the settings or dashboard which reads the cpu temp.All three sensors at the top read 32 deg F. The voltages are ok.Fan 1---3183rpm;fan 2---2636rpm & the cpu at 1596 mhz's.Nothing which gives me the cpu or anyother temps.I am going to send you an email with an attatchment of the description of the heatsink/fan which the AMD just puts their sticker on it.I think so.
And HG-- the room is pretty cold at about65--70 deg F.Well since I assembled the pc 4 months ago it is running ok & stable except for the noise of the fans which really gives me a headache after some hours of study.Well HG which would be good heatsink & without noisy fans.
Pal

[hiredgoonz]

To be honest, I don't mind the noise, so I just buy a big heatsink with a fast fan...try overclockers.com for some ideas of good fans...

And is your chip a XP1600+ or a 1600mhz XP1900+ ?

Sometimes you have to mess around with MBM to find the right sensors for it to read correctly...the forums on the website where you got it may have some posts that give you the correct settings for your board?

I wish I had more info on this but there's a new fan design out recently which is supposed to be significantly quieter. Instead of having a motor at the center it gets pushed along at the edges, it sounded interesting I can't find the link, maybe someone else knows.

Hi HG & Gallaeglagh ;
Yes the AMD is Xp-1900 running at 1600 mhz.I found out that at the mbm the cpu at bottom does gives the gauge for temp & I see the needle almost at half of the red area;which is a cause for concern? The temp is at 51 deg C / 124 deg F .
I was confused all the time when I kept checking Sys sandra with a reading at 25-- 28 deg C for Cpu.I thought I was doing ok with the cpu temp !! Untill today when I checked the reading in bios.
So what should be a optimal working temp for this cpu if the pc is running 8--10 hrs a day?
Please post if you find about the heatsink/fan if you find about that--Gallaeglagh;thanks.

First thing. Many of the temp reading programs have a temp adjustment control in them. MBM has one for each temp probe in the configuration screen.

The safest way to adjust these is using the BIOS temp monitor reading and adjust the temp reading to get a close match (+ or - 3C ) with that reading.

I have all my AMD systems setup to run at or below 50C under full load.
By replacing the stock CPU HSF and adding case fans to aid air flow.

In your MBM5 configure screen you will also find a warning alarm setting.
The cpu will melt down at or above 90C
I don’t feel safe allowing the cpu to get above 60C so i set the alarms to 58C
I also added the Shutdown program to the alarm settings.

[PPAALL]

Hi Yoda;
thanks,I'l keep postings to the forum as more of us can share.I was not sure that the email got through to you ??Thanks for putting it on the board.Why can't amd get a better cooler--a noiseless ?? I see now at other forums also that everybody using amd -cpu's are concerned about the temp's in the range of 50's -- 65's.Noise might not be a problem with the gamers but to me it's a headache.
Pal

[PPAALL]

Hi Rick;
I set up alarms in the mbm sensors 1;2;3.
But I find these alarms keep coming up inconsistently at different sensors.
Although I have changed my cpu fan & it shows a reading of 49 deg C in the bios hardware monitoring.Most of us who have assembled a pc have to deal with the noise problem.But how come the pc manufactured by HP,Compaq,Sony etc etc work noiselessly?
thanks
Pal

[Rick]

The only alarms you need to set are CPU temp and FAN speed
MBM reads the sensors at 5 second intervals by default

If they keep popping up then you may have the temp for the alarm set to low.
You are showing 49C under a full load? Or is that constant ?

The companies Like HP and others use a higher temp setting for alarms
also many use over sized Heatsinks.
One HP unit I worked on has a Pipe running in from the back of the case directly to the HSF for the CPU
One old Compaq I have worked on had a HSF on a p133 that would cool an AMD 1.2 If you mounted a fan on it

[mjc]

Also HP likes using non-standard sensor configurations....I could never MBM to work correctly on my HP... http://www.PCGuide.com/ubb/rolleyes.gif, so if you are having trouble getting meaningful data from MBM your board may not be fully supported, check the online documentation/FAQs.

[hiredgoonz]

Most home-built systems are overcooled IMO (for simple operation)...you don't need 3 case fans, or even two, really...

The PSU has a fan in it that pulls air out of the case...if the case is pretty well sealed, that will be sufficient to draw air in from the vent holes in the front and keep good airflow...

As already pointed out, huge heatsinks are common and the temp warnings aren't as much of an issue...an HP system may run the chip at 60C and not worry about it...many Compaqs don't even have temp. sensors...

Home builders are usually more careful and maybe overly concerned, but the end result is that the system runs better and more reliably than an off-the-shelf box...

If you don't have any problems with your system (lockups) then I wouldn't worry about the temp too much. I would worry if it got much over 60C...but if it ain't broke...

The only temperature read-out I really really trust is the one in the BIOS.

Yes, I have recently purchased a Zalman Flower Heatsink, CNPS6000CU, all copper unit with 92mm fan. I have been meaning to write up a little saga about my trials and tribulations with it. Maybe I can find some time this weekend to post my story. Bottom line: The Zalman cools my 1.4GHZ TBird 266Mhz FSB better than any stock HSF, but not as well as an SK-6 with a screamin Delta fan, or a Vantec CCK-6035D with a Delta screamin fan.

HOWEVER, it's quiet, compared to the Deltas. I have a more powerful 92mm fan on the way, should get it today. The 92mm fan that came with the unit is satisfactory, but I want more power Scottie. http://www.PCGuide.com/ubb/biggrin.gif

Type at yous later.

Hi Rick,MJC,HG,BB66;
thanks all for giving information.
I changed the sensors in MBM & now its steady at : Sen1-13 deg C ; Sen2-21 deg C ; Sen3-47 deg C.Well today is also cold here in NY with a temp drop of 6--8 degrees so that might effect the readings.Uptill now no random alarms.
Well this pc has been exceptionally stable.Except my concerns for the temp of the cpu & more of the noise reduction so that can help me a bit more to concentrate.I really enjoy a friends Sony desktop---Totally silent-can hear a pin drop while its running.
Well waiting to see a post for a good cpu silent cooler.
thanks to all again.
Pal

[BigBlue66]

OK, you want silent but good? Forget about the Zalman. It takes way too much tweaking to get it right.

Do you have a CompUSA near you? If so, they sell an all copper HSF that's fashioned after the Vantek CCK-6035D and rated up to 2.0GHz. And the best part is, it has an extremely quiet fan. Cost = $20 plus tax.

I just built my oldest kid a system (1.2GHz) using one and another system (1.0GHz) for a co-worker that used one as well.

The clip is kinda ornery though.

Two other HSF's to consider, if your motherboard has the room, is either the Thermalright AX-7 with a medium flow Panaflo 80mm fan, or an Alpha 8045 with the same fan.

I was going to write a saga about my Zalman flower heatsink. Well here it is: Don't get one unless your processor is not much faster than 1.0GHz. It cools my 1.4 OK, but I think I could do better. My temps average around 46-48C depending on ambient temp. Temps approach 50C when I start playing games. I consider that to be unacceptable.

Tomorrow I'm going to dig out my old Thermalright SK-6 and slap an 80mm high output Panaflo fan on it. The SK-6 was designed for a 60mm fan and uses springs to hold the fan on, but you turn the 80mm fan 1/4 turn and still use the springs to hold it on. Cool, eh?

EDIT: That's 1/8 turn, not 1/4. Gotta turn it so the corners can be used for the springs. http://www.PCGuide.com/ubb/smile.gif

If that doesn't work, then I'm going to order a 80mm to 60mm adapter and dig out my Vantec CCK-6035D and use the Panaflo fan on it.

Or, maybe I'll just venture down the road to my friendly CompUSA and buy one of those HSF's that I was raving about. http://www.PCGuide.com/ubb/smile.gif

With the amount of money I have spent on fans, regular heatsinks, flower heatsinks and blowholes, I could have gotten an XP 1800+ that's supposed to run cooler than a TBird in the first place. But then, I wouldn't have anything to tinker with. http://www.PCGuide.com/ubb/biggrin.gif

Cheers

is it true that compaq MB's don't have any sensors for heat ??

Hi BB66;
thanks,I do live close to a Compusa.Do you have the make & model # for the hsf ??
Pal

[hiredgoonz]

AS far as Compaq sensors, I know of at least one board they use that doesn't have one, it was for P3s (it was a Coppermine 733) but it does not have a sensor for the CPU...

I imagine if they did it once they would do it again, would be another way for the mobo manufacturer to cut corners on an OEM product...

Not sure if 111 degrees F. is too hot for an AMD XP 1600+ but that is how hot my processor runs on a full load (idles at 105). In fact, that is cooler thn my old P2 400 MHz processor would idle at! (120+ F) But I use a stock AMD heatsink and fan on the processor.

[Rick]

Matt
120F is 50C or there about and is in the safe temp area

[BigBlue66]

No, I don't have the part no., wish I did. But all you have to do is look up a Vantec CCK-6035D HSF on the net to get an idea of what it looks like. Then go to CompUSA and look for an all copper based unit that looks like it. On the package it will say either good up to 1.7GHz or good up to 2.0GHz. Buy the 2.0 GHz one.

50C is too hot in my book for idling. Your processor will last longer if you can get that temp down five or six degrees.

BTW, I just fired up after re-installing my SK-6 with a 40cfm Panaflo 80mm fan and am running at 45C as I type this. Woohoo! Give the ASIII three days to cure and it should run even cooler. And all I hear is air whooshing about, not the angry hair dryer that I had with my Delta.

EDIT: Oh, and BTW again, I lap all my heatsinks. Except for the Zalman, it didn't need it. It was nice and purty right out of the box.

My FIC AZ31 OEM UWAVE motherboard, which was originally for a Compaq, does not have any temp sensors. In that case, you can look for CompuNurse or DigiDoc or something like that.

Hi;
thanks to all.

[PPAALL]

Hi BB66 ;
I did went to compusa after looking up the specs & pic of Vantec cck-6035D.But the compusa in Garden City,NY which is close to me doesn't have anything like Vantec with a copper base.Maybe they have different coolers at different locations.But I'l keep checking.
Right now the MBM sesors 1;2;3; show ::: 12;21;45 deg C respectively.
Although the noise is there but this cpu reading at 45 deg C is ok.
thanks again,
pal

[BigBlue66]

If you want to send me a money order for $25 to cover the cost of the HSF and shipping, I'll go pick one up for you and ship it to you. Email me if you're interested.
