Cant get temps down ! HELP !

[LionHeartK]

Hello, im a little desperate here
i asked for help about my mem on the mem topic, but now i think my system isnt ocing cause its TOO HOT
when i put it at 166/166, my temps jumps from 38/37 idle to 42/40 idle, and nothing runs, programs give me illegal instruction errors and 3dmark wont even begin the first car chase demo without exiting on me with no error message
BUT if i cool things down with the wpcredit trick, and start 3dmark or any program, it runs fine till the temps reach around 41/39 again, then 3dmark exits and things begin to crash
i really dunno what to do, i have 4 case fans, a volcano 7 with AS3, and i removed my northbridge hsf, cleaned the thermal paste and put AS3 too, and the temps dont drop even one degree !!!!!!!!! a bud havz the same as me, case CLOSED, GENERIC fan on the cpu, and only ONE fan blowing hot air out in the back of the cpu and his temps are LOWER than mine !!!!
i tried many many many combinations for the fans, but none made the temps go down !!
HELP !!!!!!!!!!!!!!
my system:

Athlon XP 1600+ AGOIA locked
MSI Kt3 Ultra-ARU
2 sticks of 256 mb Crucial PC2700 CL 2.5
Creative Labs Geforce 4 Ti 4600
Volcano 7
generic lan card
LG 16x10x40 burner
450W PSU

my voltages are:

Idle:

Vcore = 1.74V
+5V = 4.97V
3.3V = 3.23V
+12V = 12.30V
5V Standby = 4.94V
Battery = 3.38V

load:

Vcore = 1.74V
+5V = 4.92V
3.3V = 3.22V
+12V = 12.40V
5V Standby = 4.94V
Battery = 3.38V

my fan placement is:

one 80mm fan blowing hot air out on the back of the cpu, one 80 mm on the side, above the northbridge and volcano blowing cold air in, a top 80 mm blowhole blowing air out and a 80 mm fan in the front under the HD blowing cold air in

thanks alot !!!!!!!!

idle temps mean nothing. what are your full load temps?

those temps don't seem too high anyway. shouldn't be enough to make it crash.
your volts look fine to me and your fan placement sounds pretty spot on.

i would suggest the crashing might be due to the PCI being too far out of spec. (unless that mobo has a 1/5 PCI divider. i'm not familiar with it, so i don't know)


of course without knowing your full load temps (which could rocket up to 70C for all we know) it's hard to say the temp is the cause of the problem.

full load temps are 42/40 and it begin crashing down
and yeah my 1/5 divider kicks in at 152 MHZ so at 166 everythings should be fine
maby the geforce is the villain ? or its the ram !?

i really think the problem lies elsewhere.

42 shouldn't be enough to crash it.
have you tried using less aggressive settings for your ram?
it should be able to run at 166 CAS 2.5, that's what it is rated for, but maybe you have a dodgey stick?

i don't think the vid card would be the problem. with a 1/5 divider the PCI should be in spec at 166mhz. (are you sure the 1/5 divider kicks in at 152mhz? that would put the PCI below spec. but at 166mhz it puts it bang on target. maybe it doesn't take effect until you go over 166? maybe try 167mhz and see how it goes.
