GA-MA790XT-UD4P and Backplate

[MrRight]

Hello,
is the  GA-MA790XT-UD4P's backplate in metal?

[absic]

The backplates are usually made from thin pressed metal.

Thanks, is there any possibility that the backplate is not well positioned ?, I have high temperatures and ont of the thing it could be a problem with the backplate

If we are talking about the same thing the Backplate is the part that fits into your PC chassis (case) where the Back Panel connectors of the motherboard are. If you haven't fitted this properly into your chassis it might cause problems when you connect USB or other external devices but it wouldn't normally cause increased temperatures.

When you say you have high temperatures is this within the chassis or being reported for your CPU?

If it is from inside the chassis then you might need to increase the airflow by adding some cooling fans or double checking that any installed fans are working properly.

If it is from the CPU then you need to make sure that you have installed the CPU heatsink correctly and that you have applied thermal paste properly.

Could you post a few more details about your chassis, CPU and other components, as it would make helping you a little easier.

ok:
Case: CM690
CPU:955 C2 (daily 3.6 Ghz, target 3.8Ghz)
HeatSink: Noctua NH-D14 without ULNA

MaxTemp:54°C  OCCT test @3.6Ghz (1.375v or 1.4v)/NB 2.6Ghz(1.3V)
MaxTemp:>58°C  OCCT test @3.8Ghz (1.5v)/NB 2.6Ghz (1.3V)

I have big concerns about how I have applied the thermal paste.
I was asking about the CPU-backplate, cause I heard that a metal one is better in dissipating heat.

Looking at the figures you are posting and, as I am using the same cooler, I too think your temps are a bit on the high side, even for overclocking.

When I was overclocking an X4 965 C2 140W CPU with this heatsink I was maxing out around 50° C. I think your main problem is probably with the mounting of the cooler.

I would suggest taking it off and cleaning all of the old thermal paste away. Be careful when you remove the cooler as it may have become stuck to the CPU. Once you have undone the screws gently twist the cooler to break the seal before lifting it away. I have had occasions where lifting the cooler has also pulled the CPU out of the socket.

Then reapplying some new thermal paste and remounting the cooler. Again, be careful at this stage, as too much thermal grease can cause as many problems as too little. You only need a small bead, about 2-3mm from the tube that you get with the cooler. Apply this to the centre of the base of the heatsink then, when you first put the heatsink onto the CPU give it a little twist to help spread the paste before re-tightening the mounting screws.

The CPU backplate is really there to spread the load of the heatsink as well as a cooling solution for the underside of the motherboard. I am not sure what your mobo is suplied with but it would be standard. If you have a heat problem it is nothing to do with this plate. The heatsink on the CPU should be sat on a very thin layer of thermal compound. It is only there to take upo any irregularity between the two sufaces.

Damnit absic beat me again.

Thank you very much for your suggestions. I'll try asap these afternoon
