In an attempt to make my computer silent, I replaced my stock Intel heat sink with a Thermaltake Silent 775D. The system is quieter but I am worried about the system temp. At idol the CPU is a nice cool 32c but the system temp is a good 10 degrees hotter at 42c. The smart setting from my BIOS has the fan turning at around 900 rpm.

Since I am running Ubuntu I really don't know how to check the temp at full load (which really shouldn't be much, the most taxing thing it does is play mp3s) I can't seem to get the lmsensors to work with the Intel945gc motherboard.

Anyway, the fan isn't kicking in to a higher speed so I think I am OK, but I am worried about the system temp. Is 42c and the ten degree difference something I should worry about?

I have a 92m Antec Tri Cool case fan running on the low setting. Some people have complained that the medium setting has a annoying whir, but in my system it doesn't seems too bad. I can hear it at full speed, but should I increase it a notch to keep the system temp down, or rely on the BIOS and CPU cooler to kick in if the system gets too hot?

Now the only sound I have is a slight high pitch sound from by 7200rpm hard drive. I guess I will have to get a 5400rpm quieter hard drive now.

System:
Shuttle K45
Intel 945GC motherboard
Intel Celeron 430
Pico 120 PSU
Thermaltake Silent 775D cooler
Now too LOUD 7200 rpm 120gig hard drive (that was given to me so I can't complain too much).

42c for the northbridge is perfectly fine, and 32c for the CPU is great (actually overkill, you could lower the fan speed on the CPU and be fine).

DOOH!

Not a good way to start with my first post.

I would love those #'s on my 1.8 Celery cube. I am sure the Thermaltake cooler is the key. With the stock cooler mine runs around 41-43 at idle and upper 40's when doing WP/email/web stuff.

WELCOME to SPCR!!!

Turn those fans down...
As others have said, plenty of headroom with those temps.

I was worried because the Thermaltake cooler sits up kind of high in the little K45 case and partially blocks the case fan. I knew the CPU was cool but I was worried about hot spots on the motherboard. I do not think heat pumps blow as much air down to the motherboard.

In the K45 case, even without the stock PSU, there isn't much room for the pipes on the Thermaltake Sielent 775d, so I am not sure I would recommend it. It only fits one way and it actually touches the plastic casing around the Ethernet plug. Actually, I think with a Celeron 430, it is overkill and any PMW four pin heat sink will be as quiet.

In general do heat pipes circulate less air down to the motherboard?

Have you run sensors-detect (/use/sbin/sensors-detect) - your should be able to run it as a user and it updates /etc/sysconfig/lm_sensors for you. Going through and accepting all the defaults should be fine. Then you should restart the sensors service - there is a simple way without a reboot but because I can never remember it I just reboot. If all is well you should get something like

Code: Select all

xxx@Dukla:~> sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +38.0Â°C  (crit = +90.0Â°C)

w83627dhg-isa-0290
Adapter: ISA adapter
VCore:       +0.99 V  (min =  +0.00 V, max =  +1.74 V)
in1:         +0.90 V  (min =  +0.80 V, max =  +0.98 V)
in2:        +12.10 V  (min = +11.37 V, max = +12.59 V)
in3:        +12.04 V  (min = +11.37 V, max = +12.59 V)
in4:         +1.21 V  (min =  +0.03 V, max =  +1.70 V)
in5:         +1.10 V  (min =  +0.65 V, max =  +1.66 V)
in6:         +4.99 V  (min =  +4.76 V, max =  +5.25 V)
in7:        +11.92 V  (min = +11.37 V, max = +12.59 V)
in8:        +12.04 V  (min = +11.37 V, max = +12.59 V)
Case Fan:    852 RPM  (min =    0 RPM, div = 16)
CPU Fan:       0 RPM  (min =    0 RPM, div = 128)
Aux Fan:       0 RPM  (min =    0 RPM, div = 128)
Sys Temp:    +26.0Â°C  (high = +66.0Â°C, hyst = +57.0Â°C)  sensor = thermistor
CPU Temp:    +38.0Â°C  (high = +75.0Â°C, hyst = +70.0Â°C)  sensor = diode
AUX Temp:    +46.0Â°C  (high = +75.0Â°C, hyst = +70.0Â°C)  sensor = thermistor
cpu0_vid:   +0.375 V

You can then use something like Gkrellm for a sexier display.

So... Where is the virus?

+1. I was thinking the same thing...

versus vs. virus

??

I think there's a mising 's'.

Posted: **Sun Jan 18, 2009 8:37 am**

Alright

virus = versus
idol = idle
their = there

I need a spell check that knows what word I meant to write, not the one I did write.
