Ah yes the GX270...IMHO one of the worst HW releases by Dell. Dell when maufacturing the motherboards used capacitors that were manufactured incorrectly by a 3rd party supplier. This is very easy to diagnose. Open your case and look near the heatsink/fan area you will see cylinders that have an 'X' on top. If ANY of these are swollen or have orange stuff on top then you need a new mobo.

I believe that when the caps go bad that the power lvl to the CPU fan is drained and it can't keep up with the heat. I have diagnosed and repaired 100 of these units so far with 95% being this exact problem. The other test is to put your hand near the back and see if the fan is blowing at all.

Either way you are gonna need a part

Itseems to be cpu fan problem. Normally, it is caused by cpu fan that cant work with it .

yours,

The motherboard you will get will not have these issues anymore :-) They have since replaced the capacitor supplier with a good one. I know it's a pain though isn't it?

Thanks for your advise. I followed your inspection suggestions and sure enough......yukkkkkkkkk!

New mobo on order....(new & revised... :( yeah sure))

 

Anyway thanks a bunch.

 

Normally I would agree with you but the 270 has serious motherboard issues that lead to thermal events

In addition, opti_per_Plexed may check by opeing the case cover and see if capacitors re in bulge stage. cap is another common case u may find in gx270.

yours,

Thanks for all of your suggestions and help,

 

New mobo on order,  the caps where ............. Yukkkkkkkkkkkkk.

 

 

Thanks again

Thanks for all the help from this post . . . I had the exact same problem. New mobo is on order.

Paymax you didn't read high enough I recommend checking the caps. I wish Dell would do something more about this. I had to Dispatch 22 techs for our customers for 270 failures. We had 2 entire restaurants down due to this error.

I get them next buisness day with the extended warranty. No muss, no fuss.
