Pentium 4 Temperature..

If there's a fan in the front-panel I suggest you try to turn off all case-fans ( NOT the CPU-fan ) except the one in the front and one in the back, then check the temperature readings again with closed case.

The case has 2x 80mm intake fans hidden behind that silver "mast" in front. I've got an exhast fan in the top of the case. I'll try shutting it down.

Do you suppose that reversing the top fan as an intake might help?

BTW, I really appreciate the help and welcome any suggestions!

Where are the additional fans (1*40 intake and 1*80 exhaust) you've mentioned before?

The other 80mm is the top exhast fan mentioned above. The 40mm intake is on the Aerogate II fan controller. It does not seem very powerful, so I doubt that it is having much effect beyond it immediate surroundings (DVD drive, mainly).

Not necessary.

No, don't do this.

You're welcome but it looks like I'm not really of any help at all.

One thing about the 1*40 intake on the AeroGate:
IMO you should exchange it with the Musketeer. That fan isn't really powerful at all, agree, but it looks like to me if it's cold airflow cause an overlapping with the mainflow. Put it in the upper bay, there the flow will be taken up by the cooling slots of the PSU.

Maybe you wanna try this.

I'll try that. I also may try rearranging HD's. Right now I have 2 SATA's in slots 2 & 4 (of 4) with another IDE HD ready to be installed. I separated the main HD's to keep them cool, but they are in absolutely no danger from the temp readings on them. I'll drop them to 3 & 4 and then try putting the 3rd HD in a vestigal floppy slot (w/ no front bay) just above the fans. This will give the upper of the two intake fans a clear channel to blow while the bottom fan covers both main HD's.

BTW, I figured originally the the top venting was a good idea. Nevertheless, I get the same 23.5C temp reading at the of of the case whether it's open or closed. So, either the top exhast fan is doing a great job or it's meaningless because the rear fan is pushing enough air to prevent any build-up in the top.

And, Bestia, you are definitely helping! If nothing else you've got me thinking about the issue and paying attention to the effect of any changes made! So again, thank you!

Either way, I like you.

I gotta remember to put some time aside to take some pictures of my case now that I pretter much have it done...

Yap, give it a try.
My opinion in that case is somewhat different.
I didn't/won't ever use any kind of front-panel intake fans on any system I've ever built up/I'll build up.
2 "real" exhaust-fans (no PSU-fan included) on the back with sufficient power are enough and, so my experience, much more effective.
Even if your HDs don't heat up very high, it's still no "cold" flow from the front-panel fans into the case anymore. Not mentioning the dust sucked in by these (even worse if you're smoking in front of it).
What I dislike about "your" casing is that there is only a mounting position for one 1*80 in the back, 1*90 or 2*80 would be much better (the additional top venting is meaningless).

Don't get me wrong, that doesn't mean you should take out the fans in the front-panel.
You've done a great job building it up and you should just try to optimize it.

So again, thank you!

Nothing to thank for.

So what? Nearly 2 hours since that posting. Come on, we're waiting.

I guess you could say I optimized the look and then started learning about the airflow (from Bestia). In other words, I bought the case because of it's looks... and I still stand by that decision. Now we'll just do the best we can w/ what we got!

I disabled the top fan... some small reduction in CPU temp. Then I moved the HD's to open up a better channel for the air to flow through (upper front fan is totally unabstructed) and I got a more significant drop in temps. I have not tried moving the Aerogate yet (too much work!), but after rearranging HD's the exhast fan in top of case is no longer a factor... low rpm, high rpm or off, it makes no difference to CPU temp.

I'm now showing a reading of 33.5C at "idle" and below 40C under load (though clearly not maxed). No doubt, that could be improved on, but I think I can live with it.

I also have to say, my earlier reported temps may have been a bit skewed. I realized while going through several checks that CPU temp rises when screensaver is running or in BIOS, both of which I would have expected to be the same as desktop view.

Sure, imo it looks way kewl.

Nope.
WinXP (and partially Win2k) uses some additional kind of software waterfall idle-technology to cool down the CPU a lill bit more. Temperature readings while in BIOS are usually higher, no problem there.
And running a screensaver is not idle.

Dad has the camera and my case is hidden behind my second monitor. I have to move it or the monitor to get pictures.
