XPS M1530 (BIOS A11): Vista Home Premium SP1
T9300/LG 1680x1050/256MB 8600GT/3GB/200GB FFS/DVDRW
Hi Deathrider, thanks fro the information i tried looking in task manager and the CPU is only a 3% and i've just done a fresh install of WIN Vista Ultimate 64bit
I thought it mght be the fans wires where connected directly to the PSU as a result making the fan run at a constant full speed but it doesnt seem that way as on the motherboard teh fans wires are plugged into the small socket labelled CPU FAN, looks like im going to do some more research and find out more!
Thanks any more help would be apprciated
The problem is likely a malfunctioning temp sensor or bios flash memory problem but the OP was lucky in that his system at least booted into the os.
In my case the bios post seemed to hang and the fan would go full speed while boot would not progress. This occurred on two of my dell machines a couple of years ago but as i was planning to replace them i didn't worry to much.
Bad Capacitors or improperly mounted heatsink can cause the fan to go into airplane mode.
Keep in mind however that the cooling system in dell's is passive. There are no refrigeration units.
If the room is 72 -80 degrees or warmer the fan is not going to cool the machine much.
