Hi all,  I am hoping to get your help again. 

 

I am getting a lot of fan noise coming from my pc.  My suspect is the psu causing it.

 

I am also getting random shutdowns as well.  

 

 

Is there any good software managing tools to see if the psu is outputting the correct voltages?  I don't have access to a multi meter.

Percussive maintenance around the psu location gets rid/quiets the fan noise.

Most PSU's do not report temperatures but if it is overheating it certainly might cause shut downs.

 

According to speccy your voltages were within 5% tollerances when the data was pulled:


+3.3V: 3.328 V
+5V: 4.992 V
+12V: 11.598 V
 
Which software were you using for the second image?
HWmonitor will actively monitor temps and voltages and show highs and lows if your board supports it, I would recommend you run that for a while and see if anything goes out of tollerance.
 
None of your temps in speccy looked too hot, I would still recommend dusting the computer out and while you have the case open check for blown or bulging capacitors on your mainboard and video card examples: https://www.google.com/search?q=blown+or+bulging+capacitors+motherboard&biw=1262&bih=743&source=lnms&tbm=isch&sa=X&ei=ff9sVPWfMoa8yQSAjoHIBg&ved=0CAYQ_AUoAQ

The only thing that looks not so great in speccy is your hard drive, it has 4 reallocated sectors, while this does not mean your drive is bad, drives that have reallocated sectors fail at a higher rate than drives that do not have them, I would recommend backing up your data frequently if you do not want to lose anything important.

Thanks for looking it over.  

 

I have my user profiles  being backed up to my secondary drive on a regular basis using the Windows Backup.  (I do need to test that backup tho)

 

The software used in the second one was openhardwaremonitor.   Found it at http://openhardwaremonitor.org/

Swapped out the psu.  The noise is gone as I had hoped.   (Also found out that other things in plugged into that circuit were powering off. 

 

The caps look perfectly fine.  

 

CPU cooler was taken off as well when I cleaned things up.  Do I need any of the "cream"  like artec silver when remounting the cpu cooler?

When you mount a cpu cooler you should always use new thermal paste (clean off the old and apply the new). If you do not use it, your cpu will likely run hot or overheat. That said, your temp for the cpu looks fine...

 

Your voltages look fine again:

 

+3.3V: 3.360 V
+5V: 5.040 V
+12V: 11.765 V

 

Everything looks ok in the speccy report except for the hard drive which again is showing 4 reallocated sectors.

 

Are you still experiencing shut downs with the new power supply?
