P4 3.2E (prescott) temps 2

[biosol]

Hi, anyone running a 3.2 prescott? I just upgrade my cpu today from a Celeron D 2.66Ghz to the 3.2E prescott. I've heard about cpu temps and so have been monitoring them for the first time. I'm currently running a 1.4Gh DivX movie, have one side panel of the case off and the MB temp is about 36c, the cpu1=58c, cpu2=67c. The system is stable and hasn't crashed, but I'm concerned if I use ULEAD DVD creator to render a DVD it seem it would go higher. Anyone with experience?

Thanks,

When I stopped media player playing the movie, the temps dropped to cpu1=51c, cpu2=55c very quickly. Does this seem normal?

For that cpu i would say thats probably a good temp.
but you can check at the intel site for temps for that cpu.


Good advice + great people = tek-tips

 

[biosol]

Yes, good point. They say the max for the 103W this cpu uses is about 73c. I guess mine is running fine, it's stable. I'm just kind of curious the SOYO Temp reading in the BIOS is higher close to 70c, and the hmonitor lists the 2 cpu's because of the H-T feature of the chip, but the temps are different even though there's only 1 physical chip. Seems like they should be the same??

I cant answer that part about the 2 temps, unless one temp is the ambient air in the case or another fan and one is the cpu temp. Aside from that possiblity, I dont really know. To be honest, maybe wait til someone else answers on that part.
Bcastner, the paparrazi, linney, cdogg, edfair, these are the guys who are in the know. Sure i missed a name or 2.
Still, your temp seems ok, i figured you would find that out at intel and i was right about that part anyway.

Hi biosol
check this out

http://www6.tomshardware.com/cpu/20041114/index.html

paparazi brought it to my attention.I have since added two thermaly controlled case fans a psu with two fans I also found arctic silver 5 to be better than the intel heat pad
good luck

 

[biosol]

Thanks for the info Aussie2. Intel's site says a case with a fan in the side pans is good/required. My case has 4 fan mounts and right now I've just got one in the back under the psu. I think I'll add a second to the rear and put 2 upfront to get cooler air in.

Are you using the stock (comes with the 3.2) heatsink, or the celeron one, or an aftermarket?

I would look into an aftermarket heatsink and fan if you are concerned with the temps. The 58c temp sounds about right for having a movie running, not sure what that 67 is but it is on the high end of normal under load temp..
the idle temp of ~51 seems ok, but also a little high.

My 3.0e runs ~42-43 at idle and ~51-55 under moderate load (full screen 1280x1024 game or movie).
I have 4 case fans, 1 in the top of the case pulling cool air down across the cpu and memory (and into the power supply), 1 in the front pulling cooler air in across the hard drives, 1 on the side pulling air in onto the video card, all pointing more or less towards the 1 in the back pushing warm air out. case temp is usually ambient + ~5-15 degrees.

 

[biosol]

Yes, I'm using the stock P4 heatsink that came with the cpu. I don't think I trust the temp readings in the bios. After a total cool down. I booted up checked email, replied to one, then restarted and entered the bios. It said 63c already for the cpu MB below 30c. So after restarting again, now hmonitor says 43c for the cpu1, I don't think I trust the cpu2 either (maybe it's a sensor next to the cpu or just a misreading - after all how could it be different?)

I'm going to add the extra fans anyway.

 

[biosol]

Ok, I added 3 fans, 2 cold air fronts and 1 to the existing rear for 2 in the rear plus the psu. The MB is now running at 27c, I've been doing basic work and have a DVD file playing in PowerDVD in the background and the cpu1 is about 52c. The HD temp also dropped from 33.5 to 27.

This might have done it.

Yes, anything below 65°C is considered good for a Prescott. Try to stress it out for 10 minutes or so and check the temperatures again.

[biosol]

Oh that's good to know. I ran a DivX movie for about 30-40 minutes and it went up to 57-60 (looking at my first post, I guess that's the same as before I put the extra fans in...). After quitting the movie, doing normal stuff for an hour it's at 46c. I guess I run my PVR and capture some TV show tonight and then make a DVD with ULEAD DVD MovieFactory. I guess if it stays under 65c I should be confortable it won't burn up??

Thanks

A couple of comments to help with an Intel processor.

They won't burn up; at higher temps, they simply throttle back. Your temps are fine for a prescott.

Intel ships one of the best retail coolers available with these processors; not real quiet but great coolers.

Prime95 stresses an Intel processor to the maximum. The program can be downloaded for free. An easier to use program is is Stress Prime 2004. It's also free at:

Don't be surprised is you see large temp swings between idle and full load; again, it's common with Intel P4's.

Good case cooling is essential to cool hdd's, memory, graphics chips, and the pwm circuits. Good work...looks like you're good to go.

Looks to be sorted and as SkipCox mentions, Intel P4's throttle back if they get too hot so no real fears of permanent damage.

Just as a side note and for those going the P4 route, Intel has now reworked the Prescott and addressed many of it's issues with the new 600 series.

Yeah, thanks for the info guys it ran all day today without any problems. Regular usage it's running about 45c, and gets up to near 60 when playing a DivX movie or burning a DVD movie but I guess that's normal.

 

[ceh4702]

I wonder how you are rendering the dvd. Maybe a TV Card with Hardware encoding can help. They are designed to take the load off the processor. Might even be faster.

If you do not like my post feel free to point out your opinion or my errors.

 

[biosol]

Update:
Well, after a month of working with this system it seems able to handle most everything except the 100% cpu usage stuff like backup a DVD or Rendering one. The system has restarted a couple times which I'm assuming is a temp. problem even though when it restarts it says there was a driver conflict that caused the problem.

Anyone have a suggestion for a stronger CPU heatsync and fan? Easy to install though please. Or I guess I could cut a hole in the side panel of the case and put a fan in it...? I've already got the 4 case fans going.

Thanks

I have researched after market coolers in order to solve my own prescott heat problems and it seems to me that the copper heat pipes make the most significant heat reductions but these are by no means easy to instal and most require removing motherboard and fitting a back plate alot also exceed intel and amd max weight specs it appears there is no easy fix I intend on going down the copper heat pipe path mostly because I dont like the way the 775 cooler is fitted to the cpu not a patch on the 478 socket method if I could also add a side heat tube will make your cpu fan more effective good luck

The best approach is to GET THAT COOL outside air in.

These are some of the ways to do it.

And here is the complete PDF on the cases.

[rirusstek2]

Also, the distance of the duct from the fan is very significant.

I had it at 40mm (as the case came) and the Temp was about 48ºC and when I reduced the distance to 10mm the Temp also dropped, to ~43ºC (under the same conditions of use).

So, if you do make a duct, be sure to adjust the distance between the duct and the CPU Fan.
