Personal fileserver overheats - bottlenecks throughput?

Hey guys, I've been having some issues with my PC fileserver at home overheating over something as simple as extracting a group of RAR files. Often times when I do some work on it remotely, temperature would sometimes rise to about 65C and stay there until restart.

In the not so distant past I was having overheating issues with this machine too, so I decided to purchase and install a XP-90 on it with some Arctic Silver 5 and it looked like the heat issue went away (even though it still idled at 50C, a little high for something like a XP-90 cooling it in my opinion).

Well apparently it's back now, and this time when it overheats it affects network activity as well. When downloading from newsgroups for example, I see my overall speed drop from 400+ Kbps to 50-20 Kbps, and accessing media from its hard drive on other machines becomes almost impossible because the throughput of information between it and other computers on my LAN becomes highly congested as well.

The computer is an IBM P4 Thinkcentre with 2GB of RAM, so it's not exactly just a 486 peice of junk that I decided to put to good use one day. I leave it in my room so I can capture Transport Streams from my cable box and have it double as a fileserver for now that connects wirelessly to my router.

I'm not looking for a solution more then I'm looking for just some ideas as to why my computer keeps overheating even with proper cooling, and why it overheating effects the network connectivity. Thanks in advance, ask questions if you want to know more about the machine.
 
How many Hard Disks do you have in it? I can't imagine that Thinkcentres were meant to have adequate air flow for more than one or maybe two hard disks.

Can you add more case fans, or redo the wiring to get better airflow?

Is it dusty; can you clean it?

Can you underclock the P4? P4's run hot, no doubt. 50C sounds fine. And a fileserver doesn't need too much CPU to run effectively.

Please post the complete specs and maybe even a picture of the computer outside and inside.

EDIT: And holy cow how do you have 14,000+ posts since 2005 😛

I have 2 HDD's; a primary 500GB SATA drive that holds all my data and such, and a 250GB IDE drive that I use for incremental backups of the 500GB.

I have an HDD cooler attached to my 500GB SATA, a 120mm exhaust fan, a 90mm fan on the XP-90. However, these fans rarely go above 2000 RPM.

I keep it clean enough with compressed air, the case isn't exactly the best but it's good enough to hold everything together.

The BIOS is a POS and doesn't let you OC a thing, I will try to underclock it with ClockGen when I get home though, that is a good idea.

I'll post screenshots of MMB5 temps, inside pics, outside pics, and specs when I get home.

Hah, I'm actually a lightweight now, my PPD used to be 30+ when I use to nef on ATOT most of the day at work.
