case fans

[DB]

hi
can some tell which direction the air on case fans should be flowing?
Ihave a P4 system 18.ghz 512 rdram geforce 3 ti 200 video intel 850mv mb
40 ghz wd hard drive . have 1 fan in front blowing into case and 1 rear fan
blowing out of case. both 80 mm fans. is this correct ? reason for this question my P4 processor is overheating and locking up everything
temp reaches 33'c on monitor from intel. do i need more fans?

What type of heat sink is on this?
Did this just start happening?
Is this a new system?
Have you been trying to overclock this?If it is freezing up at that temp. you got some serious problems here.
You should have two fans at the rear sucking air out One blowing in should be sufficiant for what you have.I run an ATHLON with no fans in this case only the heat sink.

P4 boxed heat sink that came with processor.
new installation, new system ,not overclocking!

[YODA74]

Did you Install this your self If not you need to take it back to the person that did becouse it is under warrenty.And you will void this warrenty trying to do this your self.

yes i built the system from bottom up !
but the fan thingys GET ME EVERYTIME!!!!!

[YODA74]

In that case you may want to go with a bigger heat sink fan. What is getting me here is the 18ghz??? no such animal,Did you mean PENTIUM 4 1.8A GHZ PGA2-478

Did you install the fan and the heat sink or did it come attatched at the factory? Why I am asking is that this processor should not be freezing up at that temp.If you installed what did you use Like Artic silver or an off the wall material that came with this?

33ºC/91.4ºF is low for a Intel 1.8 GHz.

As for the fans, you have it setup correctly.
Front fan blowing in, and other fans in back blowing out, including the PSU fan.

Either the temp monitor is setup incorrectly, or something else is causing the lockups.

or an off the wall material


LOL. First thought that came to me was someone using wall plaster on a heatsink. http://www.PCGuide.com/ubb/biggrin.gif

As stated above, 33*c is a good average temp for a Pentium; they'll actually outlast an Athlon at higher than that, so i doubt that's your problem.

If memory serves me correctly, the i850 board is RDRAM, so it's possible you have a bad stick of memory. If you have two sticks, try working with just one at a time to verify each.

If the memory isn't the problem then i'd lean towards the power supply for the P4; it has to have the extra lead plugged in to suply it with the necessary extra juice-make sure you have both leads plugged in-one for MB power and the extra lead for the P4 itself.

Other than that, i can't think of anything else.

RDRAM in pairs right?

I agree, doesn't sound like CPU temp to me either. 33°C is weel under the trouble range for that CPU. I'd say look at things like power supply, memory and video card heat.

BIOS settings could be causing trouble too, see if your BIOS has an Optimum Default or Performance Default setting and try that. After resetting it go back and check hard drive and floppy settings, make sure they stay the same but don't change anything else. For troubleshooting purposes look for Fail Safe Defaults, that should always run, but possibly not with great performance. You can go back and set Optimum or Performance later if Fail Safe works.

That said...I'm leaning toward memory or video card heat.

How many RAM slots do you have? If you have four, do you have the RDRAM installed correctly, that is, one stick in slot 1 and one stick in slot 3? Do you have those fake memory thingys in the empty slots? Sorry, can't think of the name of them right now.

It's called a continuity module, and since the machine was already working without one, I doubt one is needed. I could swear I remember hearing, however, that one is needed whenever ALL the slots are not full.

according to motherboard instructions rdram is to be in slot 0 & slot 1
and the other to thingys in slots 3&4

I agree, check the RAM and video card first. 33C is way too low to lock up a P4.

For a comparison, I have an Athlon Thunderbird 1.2GHz (266MHz bus) with a GlobalWin WBK38 heatsink/fan on it with Arctic Silver II as my thermal paste. The Arctic Silver cost me $6 and the WBK38 cost me $19, so I spent $25 extra on my CPU cooling and its temp still higher than yours: 48C. Now, if my Athlon machine can run solid at this temp, your P4 should have no problems running 15C lower, which is quite significant for CPU temps.
