Survey (Opteron temps)

irktruskan · n00b Joined: 02 Apr 2004 Posts: 7

I'm running a dual Opteron 240 setup; I'm not sure which details matter.

To the point, the processors are running in the mid 60s (C). Graphing the output from sensors does show some increase under load (and decrease afterward), but only of a few degrees. While within the specs handed down from AMD, this still strikes me as a bit warm.

Is this normal? Should I be worried?

I don't have an opteron, but I'm just curious, what kind of cooling setup have you put on there? If you went really hardcore about all of it and it's still running in the 60 C range, you might want to check that you got the thermal grease on there properly, and that the cables in the case are not getting in the way of the airflow.

Oh one other random question for you. Is the system (rather the fans and all) somewhat loud? I'm debating whether or not I should drop the money on getting and dual processor setup for myself, but noise is one of my sticking points.

Well i find odd that they reach such temps. I have a socket 939 3500+ wich i think is probably the closest cpu (after the FX series of course) to the opteron and it runs very cool. The highest temperature i got was after i finished installing gentoo from stage1 on a very hot day (+ 35º Celsius) and the BIOS showed the cpu beeing at 45 degrees and the system at 38.
I don't have any uber cooling system, my box has 4 fans (2 intake, 2 exhaust), i have 4 HD's (including 2 10k rpm ones) 2 CD readers a GeForce4 gfx and a 460W PSU. So i think that those values are a bit too high.

My dual opteron 246 machine is currently running at 43C and 47C (CPU0 and CPU1). Room temperature is 25C. System case temp is 34C.

I see temperatures increase 3-5C when i run 30min number crunching programs.

60C seems high, but what is your case/room temp? To a good approximation, Tcpu - Tcase = a constant (~13C in my case). This constant determines the effectiveness of the heatsink.

I I found the stock AMD fans (70mm) on my system ran at ~6000rpm and sounded like a vacuum cleaner. I switched to the Swifttech 64V heatsinks with quite 80mm fans, and now my system is practically inaudible until the CDROM drive spins up.

My Opterons:
--------------------

Idle
-----
CPU1 - 29C
CPU2 - 31C

Full Load
-----
CPU1 - 36C
CPU2 - 40C

I use the heatsink & fan that come with the MSI Master2 FAR, which supposedly are really good. No overclocking.

I also have 10 fans...
4 case fans (1 80mm side, 2 80mm front, 1 120mm back), ATI cooling fan, 2 CPU fans, VIA chipset fan, 2Power supply fans- an exhaust and an intake from in the case.

The CPU fans are never on (cool'n'quiet), same with the 2 front case ones (manually turned off, these things are as loud as a turbo jet).

sensors told me:
CPU0 Temp:+52.00 C
CPU1 Temp:+48.00 C
FAN1 (CPU0): 2532 RPM
FAN2 (CPU1): 2322 RPM

Tyan Thunder K8W
2 x 240, stock fans, BIOS 2.02

under load little higher fan speed and temperature.

I have to admit my FX-53/socket 940 gets super hot.
I have decent case airflow and a ThermalTake SilentBoost K8 with a thin amount of the thermal grease (arctic silver). I know it's not good to overdo that stuff either--just a thin coat is all one needs.

Right now, after playing a DVD, the CPU is at 55.5 deg C, which is normal for it. During the last heatwave my CPU reached 68.5 deg C. (top floor, bad airflow in the room) I've never seen the CPU get below 49 deg C even with a fan blowing cool air right into an open case at night.

The system is not loud at all compared to others I own, though the CPU fan never gets to throttle down in speed.

I just hope future Opterons have P-states to help combat this.

i think its the silent boost heatsinks. turns out on a couple threads ive read else where the silent boost dont perform as well as the stock hsf's from AMD. i have two silentboosts, and my temps arent as good as i like. But im about to watercool my dual ops anyways.

I can recommend the water blocks from Danger Den :-)

I have almost the same setup as you do.

mine never reaches above 45 and normaly sits at 35 but then i have seven case fans one of which sits right above the cpu and i have a thermaltake fan bigger than my fist sat on the cpu and the psu is a 440w tripple fan cooled thermaltake jobby.i do only use rounded cables and only have three drives and a dvd reader and a dvd burner in the case

CPU0: 56°C
CPU1: 52°C
Fan0: 1000-9000 rpm (Thermal Throtteling)
Fan1: ~5500 rpm

I killed my CPU0 Fan with a Floppy cable. Bought a new one after that.
CPU0 Gets hot very quick, but the fan speeds up at about 40°C.

I know Atlons that run at a minimum of 60 or 70°C.

I have a A64 running at currently ~2,3GHz overclocked too. My cooling is as follows : two 120mm PAPST silent case fans running at 4 volts (very silent), 80mm running silently in Zalman 400B-APS PSU and Zalman 7000B-ALCU CPU cooler that is running in the 20dB silent mode (~1300 rpm) and under load my CPU temp never goes higher than 46C. Guess the A64:s run... Well, the arch surely rocks, silent, cool and fast as hell

(cool as hell anyone??) Guess it is because of SOI technology.

I have dual 246 in a 1U case. They range from 46 to 57 degrees. They are at 46 when the room is like 25 and they are idle. They get to 57 when they are at 100% running setiathome and the case temp is 37 degrees. I say case temp in that instance, because I can only remember that number measured in the colo.

I use 3 fans per processor, they are Papst 412JHH, a 40 mm fan with 14cfm, running at 13,000 rpm. Check this out - they are supposed to last 8 YEARS. Also, I bought some no-name passive heat sinks for the CPUs. They have a big solid copper block, and lots' o thin fins. In the block there is a heat pipe that expands the area meeting the fins.

Dual opteron 242 on a Tyan Thunder K8W, cooled with enormous Zalman AlCU fans. I keep my system busy running seti@home and folding@home so the CPUs are always at their maximum temp:

I have a dual opteron setup with the MSI Master-2 FAR. I use MSI's "Cool'N'Quiet" which basically is keeping the CPU fans off, and I should also note I use the heatsink and fans supplied with the motherboard... as no other ones fit that are designed for socket 940's. I should also note that each HSF is different, the CPU2 fan runs at higher RPM's but has a much smaller heatsink.

Idle:
CPU1 - 109F
CPU2 - 116F
Ambient Temp: 93F
