Idle 52C - Full Load 60C

I've overclocked my 2600 barton to be a 2800 barton.
Are thet temps too high or pretty much ok? By idle I mean internet browsing,
MP3's playing, word processing... just general use. Full load was an hour of
Prime95 running the CPU at 100%. It maxed out at 60C by about minute 20 and
the temp never went higher.

 

60C is not cool by any means, but is tolorable according to the AMD site, I
have a 2500+ clocked to 3200+ and it sometimes reaches 60C, It kinda worries
me but AMD says max die temp is usually around 85 to 90 C depending on
chip...now this is not including the MP chips which I did not look up...go
to amd.com to find the max die temp for your particular chip. A little
research before asking goes a long way.......I found this info in less than
2 minutes.

I was well aware of of of that info, but was more worried about long-term
use at those temps, not when it would start to melt.

 

My computer room at my house is always relatively hot. My case temps are
typically 40 C and it is cooler during the summer when the AC is running.

I have a Barton 2500 XP+, which I have been abusing. It has a good fan, but
I run at 1.8 V which means under load the socket temp is about 65-70 C. For
most of the calculations that I run it runs about 5 C cooler, and they can
be from overnight to several days. I have a $16 HSF, I can't remember the
name at the moment but it seems to do a good job compared to other fans that
I have used.

Unfortunately at 1.8 V, I can only get 200x11 on the DFI UI motherboard. At
the same voltage, I was at 209x11 on the Epox Motherboard.

These temps are obtained from the Prime95 torture test, which I like to run
whenever I am not using the computer.

I have been doing this for a year, and the CPU has not died. I had one Epox
motherboard blow its caps, but the CPU has been fine. I think I may have a
deathwish on it, so I can replace it with a mobile CPU or AMD64 3000 chip.

Why do you run want it to run at 100% so often? I'll take it off your hands
if you still have that deathwish for it

 

Temps are all relative to ambient, although 60C seems real high to me if
that's the socket temp. To assure adequate cooling, the case temp should
be no more than 10C above room temp, and cpu temp at idle shouldn't be
more than 10C above that.. For good cooling, change the 10C to 6C. And for
better, make it 3C. This would normally require software cooling also
unless you have some special cooling system. So, 20-30-40, or 30-40-50
would only be adequate IMO. Right now I'm running 22-26-30 on an A64 3000+.

 

Because I do a lot of number crunching, and when I am
not number crunching, I want to make sure that the number crunching was
correct.

The computers are going to be obsolete before they fail. I think the only
way to get your $$$ worth is to run your systems at 100% all the time.

You also want to make sure that the systems are stable. I will keep your
offer in mind, if I decide to get rid of it.

Change the 10C to 6C... I don't get it.

 

Adequate= 20C-30C-40C
Good = 20C-26C-32C
Excellent = 20C-23C-26C

 

Adequate is full load at 40C??? I must have the hottest running Athlon ever
made because mine was 50 idle with no overclocking at all. I would need
watercooling to get it to idle at 30C. That or buy a meat locker and do all
my computing in there.

 

It was at idle load.

Not if you knew what you were doing. I had an overclocked max vcore
(1.85v) Palomino idling at 28.8C using an $8 cooler.

Room temp was 24C, MB, 27.1, CPU t4emp was 28.8C at idle.

 

My bios reads the temp as 45 but the asus software and motherboard monitor
reads it as 52, is the bios off that much??

 

Contary to popular belief, the bios puts a load on the cpu. This can be
seen if one immediately goes from a cool state OS to a reboot and then
watch the temp readings rise in the bios. In your case I'd guess the
software was off, but I don't know for sure.

 

Hopefully. I just removed some panels at the back of the case and took of
the Floppy panel in front to increase air flow. Is that a good idea or not
considering dust? My temp went down 4C.

 

The more airflow the better. You really don't need more than 1 case fan
if it's efficient (Along with PSU fan(s)). I always cut out the extra
metal for the front intake fan. And then I remove excess plastic from the
front cover to allow less resistence. If it has holes in the front, I'll
make them a lot larger. One Enlight case I had had about 16 holes in the
front cover about the size of a pencil lead. After cutting away the metal
inside and making each hole 5/16", the airflow doubled (or more) and it
was quieter because the fan was no longer being starved of air and whining.

 

Good to know. I actually dont have a case fan at all. Are those PCI fans ok?
Looks easy to install at least. Can I get any significant cooling from a
case fan or is my next step going to need to be a new heatsink/fan for the
cpu. I'm at a 2800 and happy with that, but a 3200 or 3400 would be nice
too. I've been at both speeds but they idled in the mid 50's.

 

The most important case fan is the rear exhaust fan so add one if you don't
have any case fans. Front and side fans are not usually necessary except in
extreme situations - i.e. the system is pushed to the limit - as long as the
case has adequate ventilation.

are they easy to install?

 

Sorry I disagree.

20C-23C-26C = Dreaming / Using drugs. Or perhaps wrongly calibrated
sensors.

A 3C difference between idle and load means perhaps 17W/C performance from
your cooling system. Or to put it another way, 0.0588C/W.... Or to put it
another way 4 times better than a Thermalright SLK900 and 6000 rpm fan. I
think not.

To give you another example, the Thermalright SI-90 with a 90mm fan at 5000
rpm (all 77 dBA of it) can only hold the die temp 17C above ambient. That's
probably 10C above diode at idle.

The trouble is the damned motherboard sensors are so badly calibrated,
people start to believe these sorts of reading. But they are nonsense. 10C
difference between idle and load is actually pretty good. Anything less
than 10C would need water cooling at least. 3C needs a flipping river
flowing through it.

Sorry, scrub this.

I see you mean Ambient - Case - Idle, not Case - Idle - Load. My apologies.

Still, the same rules apply for Case - Idle deltas. Assuming a power
consumption of say 20w on idle, you'd still need 3/20 = 0.15 C/W from your
heatsink. That's still better than any air cooler in existance.
