thats my specs btw i am switching to quad

now before i had a asus p5b evga 320 mb 8800 and a core 2 duo 2.7 now since i got new parts and i turn on my pc everything powers on fine but the back out take fans takes like 8 seconds longer to turn on but it turns on and runs fine just a delay..is this a problem?it is connected to the mobo the pc has no issues etc just this 1 weird problem.

It could be a defective power supply or motherboard...

Is the back fan mistakenly connected to the CPU fan connector on the motherboard? I think there can be a slight delay when the CPU heatsink fan starts up when connected to its CPU motherboard connector.

Did you buy adjustable speed FANs or temp FANs that only come are at a certain delay time? Did the fans come with the case?

Look to see if the fan is turning on at the same time the computer starts POST. It may be that the speed of this fan is controlled by the BIOS and does not start until the BIOS is initialized. I've noticed that my CPU fan spins slowly at first but upon POST it goes up to normal speed.

The CPU HSF could be the wrong type or it could be defective
