208160 2004-01-18 06:50:00 the 10 degrees or so difference between room temp and case temp usually means poor case airflow. if so removeing the sides should make the case temp go down. if it dosn't then the temp sensor may be out a bit. most server cases (which is what you should already be useing) have mounting points for multiply fans, eg several front fans as well as several rear ones. makes sure ALL rear positons are filled with fans (helps stops hot air from being sucked back in)

i would change the heatsinks on the cpu's. however what i am not to sure of is the effect of install 2 very HEAVY heatsinks on the motherboard. try the find light but big ones eg stay away from the all copper heatsinks. use some decent thermal paste and it should make a big difference.

208161 2004-01-18 07:42:00 Ok, I have a question. How do you find out at what temp your cpu will shut down?

Our computer seems to be turning off all the time, I think when it reaches about 67.

The guy at the shop says the crashing is not a temperature related problem, but if we turn it off for a while, then turn it on, it is fine, untill the temperature goes up again.

I am using AIDA 32 for the temperature, but I can not find anywhere that says the cpu shutdown temp.

My case temp is 55.

208162 2004-01-18 07:51:00 mwjobloggs- 55 case temp is bloody high! a lot of cpu's run cooler than your case is. aida is not the greatest at temps, i would suggest a better program for monitoring temps.

shutdown temp is whatever you set the bios to. crash temp depends on cpu. what cpu are you useing ?

208163 2004-01-18 07:55:00 Will order a another case,with extra fans and new CPU coolers.I need the computer to be stable so will do what it takes,to make it right. Thanks for the groups suggestions and advice.

mejoebloggs...
The shut down temp on my computer is 80.c if either CPU gets this hot the system shuts down and i have to pull out the plug to reset it. These settings are found in the the bios (in the pc health menu).

208164 2004-01-18 08:30:00 I wonder if its actually hitting the 80 degree limit. I have a recent computer here that was also sounding the alarm & cutting out because it was reading the temp sensor incorrectly.

The problem was when the temp went over ~48 degrees the reported value would get much higher than it should, reading 120 degrees when it should be at ~55 deg.

I suggest installing Motherboard monitor and watching the reported temp.

208165 2004-01-18 09:23:00 I currently have motherboard monitor 5 installed. At work i have a a temp probe multi meter and also one of those laser pointer temp tester(for the lack of the correct name). I will try to check the temp with these devices. andrewc (1143)
208166 2004-01-18 09:31:00 Yeah, I might try a different program. It might be reading it wrong. Motherboard Monitor you say? Ok then. mejobloggs (264)
208167 2004-01-18 09:50:00 Ok, I couldnt get that to work.

I am pretty sure the temperatures are correct though, because the bios says the same thing.

Also, we have another computer from the same place, and that is hot as well.

Comp 1
Athlon XP 2100
Win XP
1024mb ram
Geforce 4 Ti
Case temp 55 degrees (how do you do the symbol?)
CPU temp 65

Comp 2
Athlon XP 2000
Win XP
256mb Ram
Geforce 2
Case temp 47
cpu temp 52

Computer 1 repetedly crashes, as already said, but the company says it is nothing to do with temperature, and those temps wont hard anything.

Still got warranty, so I cant go anywhere else.

If it is the temperature crashing it, can I prove it, so they will have to fix it?

Sorry for jumping onto this thread, whoever started it, some people get annoyed, but there is no point starting a new thread, when its all here.

The setting for my computer to shut down when temp is too high is set in the computer's motherboard monitor utility installed with the motherboard's drivers. This utility monitors temperature, fan speed, voltage, etc.

208169 2004-01-19 02:29:00 It doesn't matter which way the CPU fans rotate: they move air across the heatsinks . Apart from making the heatsink work, that's just stirring the air inside the case . Once that air is heated, it has to be got rid of .


What matters is having a lot of air flowing through the case to remove heated air and replace it with cooler room air .

Try comparing the flow coming out with the side panels off and on . If there is much less flow with the covers on, you need to get more air going in .

Removing a dummy disk panel cover to make a decent sized hole might be better than fans which blow air around a drive, because of the restriction caused by the drive .

Friction causing heating of the air as it passes through a fan is (a) irrespective of the direction of flow, and (b) not a problem . It's probably even less than the heating caused by compression . . . (an inch w . g . or so pressure difference does not have a very big effect) .
