I have just upgraded my CPU from a Duron 700 to an Athlon 1300 and it looks like I might need some extra cooling. After about 2 hours running, I have experienced a crash. Once while playing FIFA 2002 and once when I was using 3D Mark 2001.

I do have a front case fan, but have never thought it was sucking much air in really. The rear of the case has holes for a small ( the holes are about 4cm apart) case fan but I'm not sure whether you can get them that small. I am trying to get one of those rear exhaust fans that use a PCI space at the rear.

Basically I was wondering if (a)the crashes I have experienced are likely to have damaged the CPU (it seems ok as I write this) and (b) do you think an exhaust port fan will help?

Also do you think that my heatsink fan would be sufficient given that I am not overclocking the CPU? I have a Dynatron heatsink model DC1206BM-H which in their web site is rated to 1.4/1.5/1.6 Ghz so that should be ok.

Please help. I have a fair amount of experience with PCs but have never had anything as fast as this so I'm not sure quite how much heat it chucks outand what to do about it!

My specs are:
Athlon 1.3 Ghz CPU (200 FSB)
Aopen AK33 motherboard (flashed to latest bios)
40Gb Maxtor UDMA 66
8.4Gb Seagate UDMA 66
2Gb Seagate UDMA 33
Creative Labs Geforce 2MX 32Mb AGP
plus all the usual bits & bobs
I'm running Windows XP

Only if the temps are really high (=70C) it will damage your CPU, but it can give instability when temps are over 50C.
Maybe you can find an old CPU fan that can be mounted in the small 40mm hole.
I never used a PCI-slot fan but if it sucks a lot of hot air out of your case it should help.
But also check if your powersupply is atleast 300W, because a lack of power can also make your system crash.

My case has so many fans that it hovers above the ground :eek: .

What tempatures are you running? Because it could be an inadequate powersupply like svol suggests. You've got 3 HDs going there...

Case fans, case fans, and more case fans

more air you can move through your case the better your heatsink will work.

Well I have now got a system exhaust fan, and also a 40mm Sunon fan sucking air in and also a hard disk fan sucking aire in and whilst in general use it is fine when I try & play a game after about 5 to 10 mins t crashes. I've decided to order a Taisol CGK760082 cooler to see if that helps.

I wonder whether the airflow is somehow missing the processor area?

check you PCI IRQ for all of your pci cards. get the latest mobo chipset drivers. get the latest nvida drivers. i once shared the blue screen of death problem. once i did all of those, i got no more blue screens.

Try running the games with the case open, if it fixes the problem then you are looking at a heat prob,which I suspect it is.

Hurrah! I have a new Taisol HSF, a thermaltake 37cfm intake fan, a 6cm fan off an existing CPU heatsink, an Akasa PCI exhaust fan and also a blue orb fan on my Geforce MX and finally it is working ok!!
