Hey guys, my pc has shut itself down on a number of occasions of what I am certain is high temperature problems. I am trying to determine whether this is my psu overheating or my cpu, as I have heard that the fx6300 temperature is about 65 degrees before it shuts down. Also I am unsure whether this is my psu as I have the corsair gs700w and the fan does not always spin, It is temperature activated but I have never actually seen it run at all, and when my pc does shut itself down (happened on a few occasions) my psu is burning hot. There is no warning when my pc shuts itself down, it just cuts the power straight away. If this isn't caused by temperature issues what could it be and how can I determine it. I can try and replace to psu if this is the problem. Otherwise I will be buying a noctua nh-d14 cpu cooler if it is the cpu causing the problem, I am using the stock cooler on my cpu at the moment.

A PSU heats up, the fans turn on to cool it. If not then the PSU (or other parts like CPU, GPU) heat up to the point of CATCHING FIRE. Safety mechnism to prevent FIRE, shut off all power when certain temperature reached.
You need to suck it up, and replace the PSU.

if the psu fan never works it's an easy ... broken psu verdict. the end.
if it does spin eventually - you can check while it's running - then it's very very unlikely but possible that the gpu is broken. in either case, if everything was fine and after psu+gpu change it's not then it has to be one of the 2.
cpu at 65C is not a problem. and since it's not the cpu to overheat another fan on it won't do anything.
with an older gpu you could test and if shuts down with the old one too it's clear it's the psu.
You need to befriend someone like me who has spare parts to test it out man. Or, as someone said, suck it up and buy a new PSU to test. It sure sounds like a defective PSU. If it was me, I'd replace the PSU fan or take it out and test it, but that's me and I do NOT recommend you doing it. You don't have a lot of options. Sometimes good qualify PSUs sell for less than $50.
The reason why I don't want to replace psu straight away is because this might not be the problem. The fan is not meant to spin until it reaches a certain temperature, like most corsair psu. The psu is Corsair GS700w. I just haven't seen the fan spin yet, this might be because it hasn't needed to and the cpu is the component overheating. Is there anything I can do to test if the psu fan works?

STOP. It isn't "the fan spinning not spinning" as the issue. The PSU draws power, when you put power over metal parts a product is HEAT (basic science 101!). The more power the more HEAT, to the point things MELT or CATCH FIRE. To stop this two parts are mandatory: Thermal Shutoff Guage and FAN/Water cooler (depending on the system design). THE PSU Fan is designed to be ALWAYS on, it just may INCREASE in speed to compensate for more drawing of power (remember more power more heat). Your saying the FAN is not spinning at all, that means the PSU is defective. Your PSU was "BURNING HOT" means your PSU is defective.
DEFECTIVE PSU MEANS REPLACING. You may not 'want to replace psu straight away' but you HAVE TO. Think of it this way, we can talk all about bad gas milage and why your not getting all the maximum MPG you want, but it still will not help anything if you have repeatedly FLAT TIRES. You may not want to replace the tires because "this might not be the problem" but you can't resolve anything else if you have FLAT TIRES.
ALL the parts of the computer need ELECTRICITY, where do they get it from? No not the wall socket, THE PSU. If the PSU is bad, they are getting BAD electricity. I will drink fresh milk, you keep drinking soured milk, BOTH from the same cow. Why do you get sick and I do not? SAME THING, change the OBVIOUS problem first then we will see if there is any other issues.
If your that refusing NUMEROUS technically savvy peoples answer then GET RID OF YOUR PC AND GET A CONSOLE!

The above is mostly correct, but there are indeed PSUs now that do not run their fans at low loads and when they are not yet hot enough. Several Seasonic units are like that. Some of their 80+ Gold units are so efficient that they produce very little waste heat.
