Need help diagnosing overheating issue.

[metroplex]

I'll try to provide as much info as possible:

Skyhawk aluminum black case:
80mm intake
60mm exhaust

Enermax 650W Power supply: 90mm + 80mm thermally controlled fans

Thermalright AX7 + Thermaltake Smart Fan (47-53 cfm depending on temperature)

Abit KX7-333 mobo
AMD Athlon XP 2100+, 13 x 141, PC2100 DDR at CL2
Stock voltages
Artic Silver 2 on the GeForce 3 core and the KT333 chipset
GeForce 3 has OEM heatsink + fan, and ramsinks

KT333 has the Abit fan + heatsink

Crucial PC2100 DDR

I have two HDs,
IBM 75GXP and Maxtor D740x. both run fairly warm (IBM is cooled down to 32-38C thanks to the alum chassis), Maxtor runs 42-50C typically


NOW the problem is:

When I built this comp a few days ago, the weather was cool - 50-70F.
Now the temp SKYROCKETED to 90F+ and my computer has been crashing every few minutes.

I am running XP Pro SP-1. I get no BSOD, it just crashes. I hit the reset and it reboots.

My system temp is around 38-40C
My CPU temp:
idles 49C
peak is about 53C

Short of throwing on a SK-6 plus a Delta 8000 RPM fan, what should I be doing?

I seriously dont think its the CPU getting too hot, because it runs 50-52C even in 60F weather and its rock solid stable.

When the ambient temp rose to 90F, the problems started.

Abit never applied thermal compound to the KT333, so I applied AS2 (Since I found I could squeeze an additional 13 MHz for the core and memory using AS2 on my GeForce 3) - but it still crashes.

What should I do???

141 MHz FSB is not high at all, I wanted to build a quiet but decent performing system (I get 9300-9400 3dmarks, with 141 FSB and GeForce at 243/543)

as you can see I'm overclocking the system but not by a whole lot.

Is my KT333 overheating?

Any ideas?
Thanks

Perhaps the chipset is overheating. You may want to check the thermal grease on the Northbridge. Abit is notorious for scrimping on the goop.

Obviously little more case ventilation would help. Have you tried running the system without the side panel on>

 

[metroplex]

As stated before Abit never bothered to put goop.

I used ASII but its still crashing with the panels on.

I took off the panels and its running better, but the whole point is to keep the panels on, make it run quiet and clean (no dust). I guess its not going to happen???

I dont see how running the stock FSB would help either. Its got to be something in there that needs cooling.

Sorry, apparently my reading skills are impaired. Sounds like more case ventilation is the answer.

 

[metroplex]

So its not the chipset overheating?

What do you suggest I do?

Right now:

I have the lower front portion cut for the 80mm intake (has a grille plus filter)

in the back towards the CPU there's a Delta 19cfm 60mm fan acting as the exhaust

and there's a slot cooler below the GF3 for venting out hot air

the Enermax exhaust fan is really slow (thermal controlled) so i dunno if its even doing anything worthwhile.

Yeah, you need a little bit better case ventilation
