Appreciate your input EmishOrc but having read the thread you should already be aware that removing the side of the case has helped with the cooling and that dan7brit is now waiting on a new PSU, nothing more to be done until the junk PSU has been swapped out.

 

If you check the Speccy report you will note that the memory controller reading is 1.672 V, in the case of a CPU that has an integrated memory controller the voltage should not exceed that of the CPU and for older MBs that have a Northbridge chip the voltage should not exceed or be below that of the Ram, 1.3V / 1.35V and 1.8V respectively.

 

Off topic here but in reply to the reply #31 of EmishOrc above;

 

If correctly applied and as long as the HS and cooling fan have not been removed or disturbed for some reason thermal paste will normally last the lifetime of the computer and/or the processor and should not need reapplying.

 

As for Arctic Silver being the best, it is what I always use but only because it is my preference and there are equally as good products out there.

Hi, I have taken another look at the PSU and it seems to be encased without any switch opening. Withy all those leads and what looks like a fiddly replacement,  I think I may just approach a hardware engineer to do the job for me.

 

One other question I have is if overheating is a problem, then has it not fried or damaged my CPU? If that is the case then a new motherboard will be needed as well.

Excuse the title of the guide but see here for how to swap out a PSU.

 

If your computer has been ok since taking the side off and the clean out then your hardware would appear to be ok.

 

Would it be possible for you to take a picture of the back of your case and upload it for us.

Hi, see attached

Have you got a model name or number for the computer so we can look for a user manual.

 

It is a standard ATX PSU but it would appear that it is held in place by TORX screws, commonly four in number but only two can be seen in your photo, you will need to borrow a TORX (star) driver to get the screws out.

The one thing that the manual does not show you is how to swap out the PSU, take a look here in case I missed it.

[dan7brit]

Hi, maybe this is a silly question, but does the new PSU have to have the same dimensions as the old one?  Evga and Corsair seem to be bigger than my old one.

[phillpower2]

Not a silly question at all, quite the opposite in fact 

 

Your PSU is a standard ATX type (have checked this here) most PSUs are around the same size and shape nowadays unless the computer is a small form factor or cube etc, you mention Corsair and EVGA but not the Seasonic here that I suggested, why pay more than you have to.

 

BTW: I still suggest that you have the present PSU tested before making any purchase.

[dan7brit]

Thanks. I may just go for a straight replacement because of what I have read about Bestec PSUs being referred to as “Worstec”, due to problems with their transistor based  circuits which cause the voltage to go way over the safe level after a few years of use and cook the motherboard. This seems to be the case for my PC.

[phillpower2]

A wise decision 

 

To help further with keeping the internal temps down I would also suggest that you fit a rear exhaust fan, this would expel the hot air and help with keeping dust build up to a minimum, if you measure the dimensions for us we can suggest one for you.

 

To summarize before making any purchase/s you should;

 

Measure the space that you have available for any replacement PSU.

 

Measure the dimensions that any rear exhaust fan must be, see my attachment below for where you need to measure.

 

Get back to us with the dimensions of both.

As per the above.

[dan7brit]

PSU length is 14cm, 10cm wide and 14cm high

 

As I mentioned previously, the Seasonic, Evga and Corsair are all slightly bigger

 

 

Rear exhaust fan is 8.5cm high by 8cm wide

It is the space that you have inside of the case that you need to measure.

 

PSUs are measured (L) X (H) X (D).

 

The (H) and (W) are fine going by your measurements but you need to check that a PSU that is the equivalent of 15cm long will fit in your case, see new attachment below.

I have ordered the Seasonic PSU and await its delivery. It is a bit longer than my old PSU, but there is a couple of centrimetres spare which should make it fit OK.
