As some of you know i just built my buddies pc for him, heres the specs:

Pentium 4 1.8GHZ
512MB SDRAM
GF4 TI4200 128MB
Maxtor 7200RPM 70GIG HDD
UltraCool ATX 12FAN Case

Anyway, i want to ensure that this thing can take the heat, so to speak. All graphics settings are stock and i 3dMARK'd it at 7093, not too shabby. I need some sort of stress test that just slams this thing with graphics/cpu usage for like 30min to an hour and allows me to monitor cpu heat and such(i can do that in the bios but i mean while running.)

I think i member having one before, cpuburn or some crap, can anyone reccomend one too me? preferable within the 20mb range, please.
