I recently made a new PC and my GPU fans aren't spinning. The LED light is on for the GPU.

Specs
430 watt PSU
AMD Athlon Multicore Processor
GPU: R9 380
 
Solution
1. The Strix 380 draws a helluva lot mote than 130 watts ... actually almost 200 (196)

2. Your PSU is undersized.

This is Guru3D's generic power supply recommendation for the R7 and R9 series:

AMD R9 380 - On your average system the card requires you to have a 500 Watt power supply unit.
AMD R9 380 Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

Fans not running could be many things:

a) cable from fan to PCB became dislodged

b) fans are not turning on because...

With some boards, the fans do not spin until it is under load and hot.
Do your fans ever spin?

which R9 380 ? ...what are GPU temps ? As noted above fans don't turn on until told to by the heat sensor.

The PSU is made from EVGA and I looked at PC part list and it said the r9 380 needed like a 130 watts.

My BIOS won't even boot up ether so I can't check temp.

The R9 380 is made by Strix.

That one part. And the rest of the system?

Does this thing even turn on?

I see people making this mistake over and over again. YOU SHOULD ALWAYS CHECK THE RECOMMENDED WATTAGE FOR THE CARD BEFORE BUYING PSUs.

Sorry for the caps, but I can't stress this enough as I've seen this done millions of times by now :)

If the OP can get a display and boot to Win, but the problem is simply that the card's fans are not running, the small PSU is not the problem. Starting and idle load for the GPU is minimal at those times. But yes, the PSU should be upgraded as soon as possible for best performance.

If the fans are not working there might be problems with bios or with the GPU chip itself.

I have a GTX 650ti BOOST that I got from my brother that does this. The fan turns on for a second after I power on, but never will again after that.. I can push it to the point of shutting itself off... in about 2 minutes. Bad card??

Fans not running could be many things:

a) cable from fan to PCB became dislodged

b) fans are not turning on because they are not hot enough to warrant it. Asus uses this feature on the 380x, dunno about the 380 but I woulkd assume so

Idle temperatures are fine with even the idle-fan-off feature we love so much.

c) PSU is balking at the load. The only PSU ever sold by EVGA at 430 watts is a cheap HEC made unit that rec'd a FAIL rating from HardOCP

This seems like the most likely cause of your problem.
