Hot!

[Guest]

Hi,
as my dual athlon 1600 was getting a bit hot with mprime torture test on
1412MHz (63°C) I started chasing the cause for this. I hoovered the whole
thing (made it cooler, but also louder, maybe you can imagine how much dust
I got out of there) but as that did not lower the temp significantly I also
got two new coolers (Zalman copper coolers with large fans mounted on a
frame atached to the expansion slots) and bought some good thermal grease
(which made a difference of mere .5°!). I still get a torture test temp of
50°C on both CPUs (MB is 37) which seems a bit much to me as I have four
additional case fans (two supply and two exhaust) that case a hell of a
hurrican rushing through the case. I doublechecked them working the correct
directions and everything is absolutely clean now.
What are your experiences, what temps might I expect?
By the way idle mode temps (when bootet to bios setup and monitored) are in
the area of 35°C).
I am planning to overclock this thing to up to 1800MHz, but I might not get
this far as it looks.

PS. thanks for your answers on earlier thread.

The grease takes awhile to break in. (Prepare for anti-$grease flames.)

50C for those under torture is ok. 35C idle is very nice.

Instability can start at 60C.

Then, too, if the measurement is under the socket, not from the cores
themselves, then they may be getting near 60C.

You could try disconnecting the zalman fans and making ducts of aluminum
tape from them to case fans. Then they wouldn't eat their own hot air. It
may or may not help.

Thanks,
I thought it looked quite ok now. I can yank it up to 1639MHz at the moment,
without either overheating or instability. But one step higher and the
kernel halts at boot.
Maybe I should be content with this, it's not too bad.

I don't think those old things could overclock much, but maybe someone who
tried it will chime in.

Both the K7D and A7M266-D tend to report higher core temperatures than a lot
of uniprocessor boards. I think it's either because they are of higher
quality (more accurate temperature measurement) or possibly just so that
there's a bit more of a safety margin. On my K7D, which reports temps
similar to the ASUS, I've had both the CPUs at 70 deg C (Barton 2500's at
140x15@1.65V for this test) under Prime95 torture-test with no stability
problems. I've dropped the voltage and FSB down to 1.45V and 133MHz
respectively and currently they are in the low 60's under load (admittedly
this is with 32 deg C room temperature compared to low 20's for the previous
situation ...).

If it's stable under Prime95 and not overvolted, then it's almost certainly
not being damaged.

Yeah, well stable it is up to 1639, so maybe I shouldn't complain.

Wow, don't wanna see your central heating bill...

No central heating bill at the moment, but I wish there was an aircon bill
.... Canberra is summer can get kinda toasty
