Is the TBird a lot hotter than the P3?

I was just helping my friend build a system and I noticed that the temp reading on his system, the 1Ghz TBird, is 50C+ while my P3 system is reading 35C. System temp is only 28C. I am afraid to stress test the system. The temp here is only idle.
At what temp is it too hot for the TBird. What is your average readings?
The heatsink that he's using is the old Alpha PFH model with the big global win on top. Here is the link
Should I set the fan to suck or to blow on this heatsink? The heatshink has rods instead of fins. The temp has now gone up to 68C and I am beginning to get errors. I also use artic silver.

What should I do guys?

Thanks.
 
My tbird is at 39 celcius, overclocked and running RC5. If his isn't doing anything in the background and running completely idle, I would say that is a tad warm. What kinda heatsink and fan is on it?
 
Bad_Dude,

As I said in hte other post, the MSI board is horrible. It uses one of the SMD resistors in the socket to try to measure temp. For that board, 50C is usually the
limit.

T-birds Run warmer than p3s. If you're comparing both at 1ghz, 1.8V, the p3 gives off 31W, whereas the t-bird will give off some 57W. So, let's assume a taisol, which would mean the p3 about 15C over ambient, whereas the t-bird some 28C over ambient. If you could actually measure core temp on a t-bird, i think most people would be in for a huge shock as to how hot they realy run.

JJ650, Depending on your motherboard, that isn't even a tad warm. I would hazard a guess, and say that it is pretty cool.

Also, any temp comparison with socket-a(socket-thermistors) setups is invalid. MB version/Bios revision, thermistor placement are some of the factors that come into play. For example, a KT7 cannot be compared to an MSI board. The KT7 UL bios and Later adds 10C to the reading. The MSI does not. The KT7 Uses a thermistor that at least touches the cpu backside, the MSI board uses an SMD resistor that rests in the base of the socket.
 
Well if I'm idle it is even cooler but crunching does warm it up and it's only a 900. I'm running 1 c cooler than he is under full load (Abit Kt7-riad mobo btw) and I assume he is idle.
My heatsink fan job is a Taisol.
 
If you're brave you can try desoldering that thermistor from the middle of the socket and replacing it with the thin film thermistor. This is the one that ABIT would package with their BX boards that couldn't read the diode on Intel cpu's. I also found them in KA7 slot A boards.

I wouldn't have an interest in this because the blue bead thermistor on my KT7A is touching the bottom of the cpu with a little bit of arctic silver on it. That's about as close to the core as you can get.

Mike, I remember an article on Tom's:

<< The AMD760 reference board gave us the chance to determine the CPU temperature very precisely using a sensor inside the socket462. >>



Everyone is being mislead!

Cheers!
 
Yes, the T-Bird does run hotter than the P3. The good news is that this doesn't affect system stability in the slightest. And TBirds overclock at least as good as P3's. AMD specs their chips to theoretically withstand up to 90`C.

So get an AMD-approved HSF, install it properly, and fuggedaboudid 😉

Well well, that explains why my CPU temp jumped up by 10C when upgrading from MSI K7TPro2A to Asus A7Pro (v1.02 motherboard has built-in Asus Thermal probe) 🙂
 
Why can't they just use a really long, thin one that you could bend up and stick between the core and the heatsink (or at least stick it to the thermal compound)?

Sometimes motherboard manufacturers are so dense. One hope is that, considering the low power goals of Palomino, it may feature an on-die thermosistor ala Intel. But then we stil have to rely on motherboard manufacturers to read it.

What you can still measure accurately is your CPU core voltage AND the ambient temperature inside your case! Use a program called radiate to determine your power dissipation of your cpu. Hopefully you can find the °C/W rating of your HSF. By doing this, you can determine the temperature of your cpu core.


Yes this is theoretical AND it would only be this high when truly 100% loaded. BurnK6.exe is a program that will make that CPU get really hot as well.

Summary: If your HSF has a °C/W rating higher than 0.50°C/W, you should look for a better one!

Cheers!
 
Any one got any idea why is the TBird is running so hot? It is now up to 55C. The reading inside the motherboard BIOS is pretty much the same. Should I change hs/f on this? Can a bad power supply do this to your CPU?
 
My Duron has been running mid 50's since Aug, although I have an external thermal probe that touches the side of the core. Which brings me to this question: I have a 1.01 rev A7V using the 1005b bios. How much, if any, does the A7V fudge the temps in order to compensate for the sub-processor probes in later revisions?
 
I have a Asus AV7 with TB 1.1GHz with Chrome Orb and it runs hot, too. I get Core temps of 55C idle and 65C while gaming. I am finding out that my Chrome orb is not as good as I was told it was.

I did find out that the TB 1.1 is can run in a CASE up to 90C.
 
Alpha's should always suck off the heatsink BTW.
That's quite a lot of heat...I dunno what's up with that....shouldn't be that high.
Check your CPU contact (proper contact).
The clip may not be applying enoguh pressure.
 
One bad thing about sticking a thermal probe/diode between the core and the heatsink is that leads for bad cooling. The probe shouldnt be a good heat conductor so the parts it is touch will run a little hotter.
