Overheating possibly help

Hi i am new here. Looked at the board previously but never signed up until now.

I have been running my old Asus K7V33 motherboard and AMD Athlon XP 2500+ cpu for a while now in an old case i have lying around.
It always used to run quite hot, the system wasn't overclocked and ran at 63c at idle (using Asus Probe)
I purchased a new artic cooling silentium case and inserted all these components into it. The idle temp now is 71c with the side panel off!

when running games such as battlefield 2, doom 3 etc.. the computer will switch off at random times and there will be nothing to make me assume that the cpu has overheated except when switching the computer back on the motherboard reports "the cpu has failed system check". If i restart the computer once more it will go back into windows but it may crash again.

Any ideas why i have this problem? i am using the same components and the fan constantly runs at 7000+ RPM.

I previously could run my cpu at 2Ghz without any problems and another 30mhz on my graphics card. I thought this case would make it cooler somehow with the sides on.
 
The cpu cooler is a large copper heatsink, it has 2 heat transfer pipes out of one side that run through the fins, its a pretty big beast, the fan is a high speed unit that came with it, i aquired this from a friend who bought something even larger.

The fan is plugged into the motherboard directly and i can monitor its speed with the asus probe.

I will buy some more thermal paste and reattach it.

I need a silent fan as my pc sounds like it has a jet engine inside, any reccomendations?
 
I think its a 2" fan, currently the PC is pretty quiet. The hard drive sits in its aluminium caddy and doesn't make a whisper and the 4 other fans don't appear to make any noise whatsoever.

The CPU fan makes all the noise in this case unfortunately.

Is it worth replacing the heatsink at the same time? There seem to be some interesting designs out now.
 
Well i am just about to order some new thermal compound, Arctic silver 5 is currently the best stuff about at the moment isn't it?

i can get it for £4.64inc VAT + £3.30 shipping, know anywhere cheaper.

I guess once i have cleaned it up then i can take a look at replacing the fan, never know if it runs cooler the fan may not need to turn itself on full, the asus motherboard apparently can adjust the fan speed itself and does slow down to 5000rpm sometimes, usually only on booting.
 
After cleaning up the CPU and using arctic silver 5 my cpu is running at 51c, the motherboard is running at 30c, the CPU temp has crept up since switching it on (it started at 41c) but it seems to have stablised.

The fan isn't even kicking in at maximum speed :)
4500rpm is my idle speed.

These temps are a lot better than what i was getting before, maybe i can go back to overclocking it again.

what do you think is acceptable with the motherboard/cpu combination.
